helm

Description

Specify a Helm chart (either in your repository or remote from a registry) to deploy. Refer to the Helm guide for usage instructions.

Below is the full schema reference. For an introduction to configuring Garden modules, please look at our Configuration guide.

The first section contains the complete YAML schema, and the second section describes each schema key.

helm modules also export values that are available in template strings. See the Outputs section below for details.

Complete YAML Schema

The values in the schema below are the default values.

# The schema version of this config (currently not used).
apiVersion: garden.io/v0

kind: Module

# The type of this module.
type:

# The name of this module.
name:

# Specify how to build the module. Note that plugins may define additional keys on this object.
build:
  # A list of modules that must be built before this module is built.
  dependencies:
    - # Module name to build ahead of this module.
      name:

      # Specify one or more files or directories to copy from the built dependency to this module.
      copy:
        - # POSIX-style path or filename of the directory or file(s) to copy to the target.
          source:

          # POSIX-style path or filename to copy the directory or file(s), relative to the build directory.
          # Defaults to the same as source path.
          target:

  # Maximum time in seconds to wait for build to finish.
  timeout: 1200

# A description of the module.
description:

# Set this to `true` to disable the module. You can use this with conditional template strings to disable modules
# based on, for example, the current environment or other variables (e.g. `disabled: ${environment.name == "prod"}`).
# This can be handy when you only need certain modules for specific environments, e.g. only for development.
#
# Disabling a module means that any services, tasks and tests contained in it will not be deployed or run. It also
# means that the module is not built _unless_ it is declared as a build dependency by another enabled module (in which
# case building this module is necessary for the dependant to be built).
#
# If you disable the module, and its services, tasks or tests are referenced as _runtime_ dependencies, Garden will
# automatically ignore those dependency declarations. Note however that template strings referencing the module's
# service or task outputs (i.e. runtime outputs) will fail to resolve when the module is disabled, so you need to make
# sure to provide alternate values for those if you're using them, using conditional expressions.
disabled: false

# Specify a list of POSIX-style paths or globs that should be regarded as the source files for this module. Files that
# do *not* match these paths or globs are excluded when computing the version of the module, when responding to
# filesystem watch events, and when staging builds.
#
# Note that you can also _exclude_ files using the `exclude` field or by placing `.gardenignore` files in your source
# tree, which use the same format as `.gitignore` files. See the [Configuration Files
# guide](https://docs.garden.io/v/acorn-0.12/using-garden/configuration-overview#including-excluding-files-and-directories)
# for details.
#
# Also note that specifying an empty list here means _no sources_ should be included.
#
# If neither `include` nor `exclude` is set, and the module has local chart sources, Garden
# automatically sets `include` to: `["*", "charts/**/*", "templates/**/*"]`.
#
# If neither `include` nor `exclude` is set and the module specifies a remote chart, Garden
# automatically sets `ìnclude` to `[]`.
include:

# Specify a list of POSIX-style paths or glob patterns that should be excluded from the module. Files that match these
# paths or globs are excluded when computing the version of the module, when responding to filesystem watch events,
# and when staging builds.
#
# Note that you can also explicitly _include_ files using the `include` field. If you also specify the `include`
# field, the files/patterns specified here are filtered from the files matched by `include`. See the [Configuration
# Files
# guide](https://docs.garden.io/v/acorn-0.12/using-garden/configuration-overview#including-excluding-files-and-directories)
# for details.
#
# Unlike the `modules.exclude` field in the project config, the filters here have _no effect_ on which files and
# directories are watched for changes. Use the project `modules.exclude` field to affect those, if you have large
# directories that should not be watched for changes.
exclude:

# A remote repository URL. Currently only supports git servers. Must contain a hash suffix pointing to a specific
# branch or tag, with the format: <git remote url>#<branch|tag>
#
# Garden will import the repository source code into this module, but read the module's config from the local
# garden.yml file.
repositoryUrl:

# When false, disables pushing this module to remote registries.
allowPublish: true

# A list of files to write to the module directory when resolving this module. This is useful to automatically
# generate (and template) any supporting files needed for the module.
generateFiles:
  - # POSIX-style filename to read the source file contents from, relative to the path of the module (or the
    # ModuleTemplate configuration file if one is being applied).
    # This file may contain template strings, much like any other field in the configuration.
    sourcePath:

    # POSIX-style filename to write the resolved file contents to, relative to the path of the module source directory
    # (for remote modules this means the root of the module repository, otherwise the directory of the module
    # configuration).
    #
    # Note that any existing file with the same name will be overwritten. If the path contains one or more
    # directories, they will be automatically created if missing.
    targetPath:

    # By default, Garden will attempt to resolve any Garden template strings in source files. Set this to false to
    # skip resolving template strings. Note that this does not apply when setting the `value` field, since that's
    # resolved earlier when parsing the configuration.
    resolveTemplates: true

    # The desired file contents as a string.
    value:

# A map of variables scoped to this particular module. These are resolved before any other parts of the module
# configuration and take precedence over project-scoped variables. They may reference project-scoped variables, and
# generally use any template strings normally allowed when resolving modules.
variables:

# Specify a path (relative to the module root) to a file containing variables, that we apply on top of the
# module-level `variables` field.
#
# The format of the files is determined by the configured file's extension:
#
# * `.env` - Standard "dotenv" format, as defined by [dotenv](https://github.com/motdotla/dotenv#rules).
# * `.yaml`/`.yml` - YAML. The file must consist of a YAML document, which must be a map (dictionary). Keys may
# contain any value type.
# * `.json` - JSON. Must contain a single JSON _object_ (not an array).
#
# _NOTE: The default varfile format will change to YAML in Garden v0.13, since YAML allows for definition of nested
# objects and arrays._
#
# To use different module-level varfiles in different environments, you can template in the environment name
# to the varfile name, e.g. `varfile: "my-module.${environment.name}.env` (this assumes that the corresponding
# varfiles exist).
varfile:

# Whether to set the --atomic flag during installs and upgrades. Set to false if e.g. you want to see more information
# about failures and then manually roll back, instead of having Helm do it automatically on failure.
atomicInstall: true

# The name of another `helm` module to use as a base for this one. Use this to re-use a Helm chart across multiple
# services. For example, you might have an organization-wide base chart for certain types of services.
# If set, this module will by default inherit the following properties from the base module: `serviceResource`,
# `values`
# Each of those can be overridden in this module. They will be merged with a JSON Merge Patch (RFC 7396).
base:

# A valid Helm chart name or URI (same as you'd input to `helm install`). Required if the module doesn't contain the
# Helm chart itself.
chart:

# The path, relative to the module path, to the chart sources (i.e. where the Chart.yaml file is, if any). Not used
# when `base` is specified.
chartPath: .

# List of names of services that should be deployed before this chart.
dependencies: []

# Specifies which files or directories to sync to which paths inside the running containers of the service when it's
# in dev mode, and overrides for the container command and/or arguments.
#
# Note that `serviceResource` must also be specified to enable dev mode.
#
# Dev mode is enabled when running the `garden dev` command, and by setting the `--dev` flag on the `garden deploy`
# command.
#
# See the [Code Synchronization guide](https://docs.garden.io/v/acorn-0.12/guides/code-synchronization-dev-mode) for
# more information.
devMode:
  # Override the default container arguments when in dev mode.
  args:

  # Override the default container command (i.e. entrypoint) when in dev mode.
  command:

  # Specify one or more source files or directories to automatically sync with the running container.
  sync:
    - # POSIX-style absolute path to sync the directory to inside the container. The root path (i.e. "/") is not
      # allowed.
      target:

      # Specify a list of POSIX-style paths or glob patterns that should be excluded from the sync.
      #
      # `.git` directories and `.garden` directories are always ignored.
      exclude:

      # POSIX-style path of the directory to sync to the target. Can be either a relative or an absolute path.
      # Defaults to the module's top-level directory if no value is provided.

      defaultGroup:

  # Optionally specify the name of a specific container to sync to. If not specified, the first container in the
  # workload is used.
  containerName:

# Configures the local application which will send and receive network requests instead of the target resource
# specified by `serviceResource`.
#
# Note that `serviceResource` must also be specified to enable local mode. Local mode configuration for the
# `kubernetes` module type relies on the `serviceResource.kind` and `serviceResource.name` fields to select a target
# Kubernetes resource.
#
# The `serviceResource.containerName` field is not used by local mode configuration.
# Note that `localMode` uses its own field `containerName` to specify a target container name explicitly.
#
# The selected container of the target Kubernetes resource will be replaced by a proxy container which runs an SSH
# server to proxy requests.
# Reverse port-forwarding will be automatically configured to route traffic to the locally deployed application and
# back.
#
# Local mode is enabled by setting the `--local` option on the `garden deploy` or `garden dev` commands.
# Local mode always takes the precedence over dev mode if there are any conflicting service names.
#
# Health checks are disabled for services running in local mode.
#
# See the [Local Mode guide](https://docs.garden.io/v/acorn-0.12/guides/running-service-in-local-mode) for more
# information.

      local:

      # The remote port to be used for reverse port-forward.
      remote:

  # The command to run the local application. If not present, then the local application should be started manually.
  command:

  # Specifies restarting policy for the local application. By default, the local application will be restarting
  # infinitely with 1000ms between attempts.
  restart:
    # Delay in milliseconds between the local application restart attempts. The default value is 1000ms.
    delayMsec: 1000

    # Max number of the local application restarts. Unlimited by default.
    max: .inf

  # The name of the target container. The first available container will be used if this field is not defined.
  containerName:

# A valid Kubernetes namespace name. Must be a valid RFC1035/RFC1123 (DNS) label (may contain lowercase letters,
# numbers and dashes, must start with a letter, and cannot end with a dash) and must not be longer than 63 characters.
namespace:

# Manually specify port forwards that Garden should set up when deploying in dev or watch mode. If specified, these
# override the auto-detection of forwardable ports, so you'll need to specify the full list of port forwards to
# create.
portForwards:
  - # An identifier to describe the port forward.
    name:

    # The full resource kind and name to forward to, e.g. Service/my-service or Deployment/my-deployment. Note that
    # Garden will not validate this ahead of attempting to start the port forward, so you need to make sure this is
    # correctly set. The types of resources supported will match that of the `kubectl port-forward` CLI command.
    resource:

    # The port number on the remote resource to forward to.
    targetPort:

    # The _preferred_ local port to forward from. If none is set, a random port is chosen. If the specified port is
    # not available, a warning is shown and a random port chosen instead.
    localPort:

# Optionally override the release name used when installing (defaults to the module name).
releaseName:

# The repository URL to fetch the chart from.
repo:

# The Deployment, DaemonSet or StatefulSet or Pod that Garden should regard as the _Garden service_ in this module
# (not to be confused with Kubernetes Service resources).
#
# This can either reference a workload (i.e. a Deployment, DaemonSet or StatefulSet) via the `kind` and `name` fields,
# or a Pod via the `podSelector` field.
#
# Because a Helm chart can contain any number of Kubernetes resources, this needs to be specified for certain Garden
# features and commands to work, such as hot-reloading.
serviceResource:
  # The type of Kubernetes resource to sync files to.
  kind: Deployment

kind

type

The type of this module.

Example:

type: "container"

name

The name of this module.

Example:

name: "my-sweet-module"

build

Specify how to build the module. Note that plugins may define additional keys on this object.

build.dependencies[]

build > dependencies

A list of modules that must be built before this module is built.

Example:

build:
  ...
  dependencies:
    - name: some-other-module-name

build.dependencies[].name

build > dependencies > name

Module name to build ahead of this module.

build.dependencies[].copy[]

Specify one or more files or directories to copy from the built dependency to this module.

build.dependencies[].copy[].source

build > dependencies > copy > source

POSIX-style path or filename of the directory or file(s) to copy to the target.

build.dependencies[].copy[].target

build > dependencies > copy > target

POSIX-style path or filename to copy the directory or file(s), relative to the build directory. Defaults to the same as source path.

build.timeout

build > timeout

Maximum time in seconds to wait for build to finish.

description

A description of the module.

disabled

Set this to true to disable the module. You can use this with conditional template strings to disable modules based on, for example, the current environment or other variables (e.g. disabled: ${environment.name == "prod"}). This can be handy when you only need certain modules for specific environments, e.g. only for development.

Disabling a module means that any services, tasks and tests contained in it will not be deployed or run. It also means that the module is not built unless it is declared as a build dependency by another enabled module (in which case building this module is necessary for the dependant to be built).

If you disable the module, and its services, tasks or tests are referenced as runtime dependencies, Garden will automatically ignore those dependency declarations. Note however that template strings referencing the module's service or task outputs (i.e. runtime outputs) will fail to resolve when the module is disabled, so you need to make sure to provide alternate values for those if you're using them, using conditional expressions.

include[]

Specify a list of POSIX-style paths or globs that should be regarded as the source files for this module. Files that do not match these paths or globs are excluded when computing the version of the module, when responding to filesystem watch events, and when staging builds.

Note that you can also exclude files using the exclude field or by placing .gardenignore files in your source tree, which use the same format as .gitignore files. See the Configuration Files guide for details.

Also note that specifying an empty list here means no sources should be included.

If neither include nor exclude is set, and the module has local chart sources, Garden automatically sets include to: ["*", "charts/**/*", "templates/**/*"].

If neither include nor exclude is set and the module specifies a remote chart, Garden automatically sets ìnclude to [].

Example:

include:
  - Dockerfile
  - my-app.js

exclude[]

Specify a list of POSIX-style paths or glob patterns that should be excluded from the module. Files that match these paths or globs are excluded when computing the version of the module, when responding to filesystem watch events, and when staging builds.

Note that you can also explicitly include files using the include field. If you also specify the include field, the files/patterns specified here are filtered from the files matched by include. See the Configuration Files guide for details.

Unlike the modules.exclude field in the project config, the filters here have no effect on which files and directories are watched for changes. Use the project modules.exclude field to affect those, if you have large directories that should not be watched for changes.

Example:

exclude:
  - tmp/**/*
  - '*.log'

repositoryUrl

A remote repository URL. Currently only supports git servers. Must contain a hash suffix pointing to a specific branch or tag, with the format: #<branch|tag>

Garden will import the repository source code into this module, but read the module's config from the local garden.yml file.

Example:

repositoryUrl: "git+https://github.com/org/repo.git#v2.0"

allowPublish

When false, disables pushing this module to remote registries.

generateFiles[]

A list of files to write to the module directory when resolving this module. This is useful to automatically generate (and template) any supporting files needed for the module.

generateFiles[].sourcePath

generateFiles > sourcePath

POSIX-style filename to read the source file contents from, relative to the path of the module (or the ModuleTemplate configuration file if one is being applied). This file may contain template strings, much like any other field in the configuration.

generateFiles[].targetPath

generateFiles > targetPath

POSIX-style filename to write the resolved file contents to, relative to the path of the module source directory (for remote modules this means the root of the module repository, otherwise the directory of the module configuration).

Note that any existing file with the same name will be overwritten. If the path contains one or more directories, they will be automatically created if missing.

generateFiles[].resolveTemplates

generateFiles > resolveTemplates

By default, Garden will attempt to resolve any Garden template strings in source files. Set this to false to skip resolving template strings. Note that this does not apply when setting the value field, since that's resolved earlier when parsing the configuration.

generateFiles[].value

generateFiles > value

The desired file contents as a string.

variables

A map of variables scoped to this particular module. These are resolved before any other parts of the module configuration and take precedence over project-scoped variables. They may reference project-scoped variables, and generally use any template strings normally allowed when resolving modules.

varfile

Specify a path (relative to the module root) to a file containing variables, that we apply on top of the module-level variables field.

The format of the files is determined by the configured file's extension:

  • .env - Standard "dotenv" format, as defined by dotenv.

  • .yaml/.yml - YAML. The file must consist of a YAML document, which must be a map (dictionary). Keys may contain any value type.

  • .json - JSON. Must contain a single JSON object (not an array).

NOTE: The default varfile format will change to YAML in Garden v0.13, since YAML allows for definition of nested objects and arrays.

To use different module-level varfiles in different environments, you can template in the environment name to the varfile name, e.g. varfile: "my-module.${environment.name}.env (this assumes that the corresponding varfiles exist).

Example:

varfile: "my-module.env"

atomicInstall

Whether to set the --atomic flag during installs and upgrades. Set to false if e.g. you want to see more information about failures and then manually roll back, instead of having Helm do it automatically on failure.

base

The name of another helm module to use as a base for this one. Use this to re-use a Helm chart across multiple services. For example, you might have an organization-wide base chart for certain types of services. If set, this module will by default inherit the following properties from the base module: serviceResource, values Each of those can be overridden in this module. They will be merged with a JSON Merge Patch (RFC 7396).

Example:

base: "my-base-chart"

chart

A valid Helm chart name or URI (same as you'd input to helm install). Required if the module doesn't contain the Helm chart itself.

Example:

chart: "ingress-nginx"

chartPath

The path, relative to the module path, to the chart sources (i.e. where the Chart.yaml file is, if any). Not used when base is specified.

dependencies[]

List of names of services that should be deployed before this chart.

devMode

Specifies which files or directories to sync to which paths inside the running containers of the service when it's in dev mode, and overrides for the container command and/or arguments.

Note that serviceResource must also be specified to enable dev mode.

Dev mode is enabled when running the garden dev command, and by setting the --dev flag on the garden deploy command.

See the Code Synchronization guide for more information.

devMode.args[]

devMode > args

Override the default container arguments when in dev mode.

devMode.command[]

devMode > command

Override the default container command (i.e. entrypoint) when in dev mode.

devMode.sync[]

devMode > sync

Specify one or more source files or directories to automatically sync with the running container.

devMode.sync[].target

devMode > sync > target

POSIX-style absolute path to sync the directory to inside the container. The root path (i.e. "/") is not allowed.

Example:

devMode:
  ...
  sync:
    - target: "/app/src"

devMode.sync[].exclude[]

devMode > sync > exclude

Specify a list of POSIX-style paths or glob patterns that should be excluded from the sync.

.git directories and .garden directories are always ignored.

Example:

devMode:
  ...
  sync:
    - exclude:
        - dist/**/*
        - '*.log'

devMode.sync[].source

devMode > sync > source

POSIX-style path of the directory to sync to the target. Can be either a relative or an absolute path. Defaults to the module's top-level directory if no value is provided.

Example:

devMode:
  ...
  sync:
    - source: "src"

devMode.sync[].mode

devMode > sync > mode

The sync mode to use for the given paths. See the Dev Mode guide for details.

devMode.sync[].defaultFileMode

devMode > sync > defaultFileMode

The default permission bits, specified as an octal, to set on files at the sync target. Defaults to 0600 (user read/write). See the Mutagen docs for more information.

devMode.sync[].defaultDirectoryMode

devMode > sync > defaultDirectoryMode

The default permission bits, specified as an octal, to set on directories at the sync target. Defaults to 0700 (user read/write). See the Mutagen docs for more information.

devMode.sync[].defaultOwner

devMode > sync > defaultOwner

Set the default owner of files and directories at the target. Specify either an integer ID or a string name. See the Mutagen docs for more information.

devMode.sync[].defaultGroup

devMode > sync > defaultGroup

Set the default group on files and directories at the target. Specify either an integer ID or a string name. See the Mutagen docs for more information.

devMode.containerName

devMode > containerName

Optionally specify the name of a specific container to sync to. If not specified, the first container in the workload is used.

localMode

Configures the local application which will send and receive network requests instead of the target resource specified by serviceResource.

Note that serviceResource must also be specified to enable local mode. Local mode configuration for the kubernetes module type relies on the serviceResource.kind and serviceResource.name fields to select a target Kubernetes resource.

The serviceResource.containerName field is not used by local mode configuration. Note that localMode uses its own field containerName to specify a target container name explicitly.

The selected container of the target Kubernetes resource will be replaced by a proxy container which runs an SSH server to proxy requests. Reverse port-forwarding will be automatically configured to route traffic to the locally deployed application and back.

Local mode is enabled by setting the --local option on the garden deploy or garden dev commands. Local mode always takes the precedence over dev mode if there are any conflicting service names.

Health checks are disabled for services running in local mode.

See the Local Mode guide for more information.

localMode.ports[]

localMode > ports

The reverse port-forwards configuration for the local application.

localMode.ports[].local

localMode > ports > local

The local port to be used for reverse port-forward.

localMode.ports[].remote

localMode > ports > remote

The remote port to be used for reverse port-forward.

localMode.command[]

localMode > command

The command to run the local application. If not present, then the local application should be started manually.

localMode.restart

localMode > restart

Specifies restarting policy for the local application. By default, the local application will be restarting infinitely with 1000ms between attempts.

localMode.restart.delayMsec

localMode > restart > delayMsec

Delay in milliseconds between the local application restart attempts. The default value is 1000ms.

localMode.restart.max

localMode > restart > max

Max number of the local application restarts. Unlimited by default.

localMode.containerName

localMode > containerName

The name of the target container. The first available container will be used if this field is not defined.

namespace

A valid Kubernetes namespace name. Must be a valid RFC1035/RFC1123 (DNS) label (may contain lowercase letters, numbers and dashes, must start with a letter, and cannot end with a dash) and must not be longer than 63 characters.

portForwards[]

Manually specify port forwards that Garden should set up when deploying in dev or watch mode. If specified, these override the auto-detection of forwardable ports, so you'll need to specify the full list of port forwards to create.

portForwards[].name

portForwards > name

An identifier to describe the port forward.

portForwards[].resource

portForwards > resource

The full resource kind and name to forward to, e.g. Service/my-service or Deployment/my-deployment. Note that Garden will not validate this ahead of attempting to start the port forward, so you need to make sure this is correctly set. The types of resources supported will match that of the kubectl port-forward CLI command.

portForwards[].targetPort

portForwards > targetPort

The port number on the remote resource to forward to.

portForwards[].localPort

portForwards > localPort

The preferred local port to forward from. If none is set, a random port is chosen. If the specified port is not available, a warning is shown and a random port chosen instead.

releaseName

Optionally override the release name used when installing (defaults to the module name).

repo

The repository URL to fetch the chart from.

serviceResource

The Deployment, DaemonSet or StatefulSet or Pod that Garden should regard as the Garden service in this module (not to be confused with Kubernetes Service resources).

This can either reference a workload (i.e. a Deployment, DaemonSet or StatefulSet) via the kind and name fields, or a Pod via the podSelector field.

Because a Helm chart can contain any number of Kubernetes resources, this needs to be specified for certain Garden features and commands to work, such as hot-reloading.

serviceResource.kind

serviceResource > kind

The type of Kubernetes resource to sync files to.

serviceResource.containerName

serviceResource > containerName

The name of a container in the target. Specify this if the target contains more than one container and the main container is not the first container in the spec.

serviceResource.podSelector

serviceResource > podSelector

A map of string key/value labels to match on any Pods in the namespace. When specified, a random ready Pod with matching labels will be picked as a target, so make sure the labels will always match a specific Pod type.

serviceResource.name

serviceResource > name

The name of the resource to sync to. If the chart contains a single resource of the specified Kind, this can be omitted.

This can include a Helm template string, e.g. '{{ template "my-chart.fullname" . }}'. This allows you to easily match the dynamic names given by Helm. In most cases you should copy this directly from the template in question in order to match it. Note that you may need to add single quotes around the string for the YAML to be parsed correctly.

serviceResource.containerModule

serviceResource > containerModule

The Garden module that contains the sources for the container. This needs to be specified under serviceResource in order to enable hot-reloading and dev mode, but is not necessary for tasks and tests.

Must be a container module, and for hot-reloading to work you must specify the hotReload field on the container module (not required for dev mode).

Note: If you specify a module here, you don't need to specify it additionally under build.dependencies.

Example:

serviceResource:
  ...
  containerModule: "my-container-module"

serviceResource.hotReloadArgs[]

serviceResource > hotReloadArgs

If specified, overrides the arguments for the main container when running in hot-reload mode.

Example:

serviceResource:
  ...
  hotReloadArgs:
    - nodemon
    - my-server.js

skipDeploy

Set this to true if the chart should only be built, but not deployed as a service. Use this, for example, if the chart should only be used as a base for other modules.

tasks[]

tasks[].name

tasks > name

The name of the task.

tasks[].description

tasks > description

A description of the task.

tasks[].dependencies[]

tasks > dependencies

The names of any tasks that must be executed, and the names of any services that must be running, before this task is executed.

tasks[].disabled

tasks > disabled

Set this to true to disable the task. You can use this with conditional template strings to enable/disable tasks based on, for example, the current environment or other variables (e.g. enabled: ${environment.name != "prod"}). This can be handy when you only want certain tasks to run in specific environments, e.g. only for development.

Disabling a task means that it will not be run, and will also be ignored if it is declared as a runtime dependency for another service, test or task.

Note however that template strings referencing the task's outputs (i.e. runtime outputs) will fail to resolve when the task is disabled, so you need to make sure to provide alternate values for those if you're using them, using conditional expressions.

tasks[].timeout

tasks > timeout

Maximum duration (in seconds) of the task's execution.

tasks[].cacheResult

tasks > cacheResult

Set to false if you don't want the task's result to be cached. Use this if the task needs to be run any time your project (or one or more of the task's dependants) is deployed. Otherwise the task is only re-run when its version changes (i.e. the module or one of its dependencies is modified), or when you run garden run task.

tasks[].command[]

tasks > command

Example:

tasks:
  - command:
      - /bin/sh
      - '-c'

tasks:
  - env:
        - MY_VAR: some-value
          MY_SECRET_VAR:
            secretRef:
              name: my-secret
              key: some-key

Example:

tasks:
  - artifacts:
      - target: "outputs/foo/"

tasks[].resource

tasks > resource

The Deployment, DaemonSet or StatefulSet or Pod that Garden should use to execute this task. If not specified, the serviceResource configured on the module will be used. If neither is specified, an error will be thrown.

This can include a Helm template string, e.g. '{{ template "my-chart.fullname" . }}'. This allows you to easily match the dynamic names given by Helm. In most cases you should copy this directly from the template in question in order to match it. Note that you may need to add single quotes around the string for the YAML to be parsed correctly.

tasks[].resource.containerModule

tasks > resource > containerModule

The Garden module that contains the sources for the container. This needs to be specified under serviceResource in order to enable hot-reloading and dev mode, but is not necessary for tasks and tests.

Must be a container module, and for hot-reloading to work you must specify the hotReload field on the container module (not required for dev mode).

values

Map of values to pass to Helm when rendering the templates. May include arrays and nested objects. When specified, these take precedence over the values in the values.yaml file (or the files specified in valueFiles).

valueFiles[]

Specify value files to use when rendering the Helm chart. These will take precedence over the values.yaml file bundled in the Helm chart, and should be specified in ascending order of precedence. Meaning, the last file in this list will have the highest precedence.

If you also specify keys under the values field, those will effectively be added as another file at the end of this list, so they will take precedence over other files listed here.

Note that the paths here should be relative to the module root, and the files should be contained in your module directory.

Outputs

Module Outputs

The following keys are available via the ${modules.<module-name>} template string key for helm modules.

${modules.<module-name>.buildPath}

The build path of the module.

Example:

The current version of the module.

Example:

my-variable: ${modules.my-module.version}

${modules.<module-name>.outputs.release-name}

The Helm release name of the service.

Service Outputs

The following keys are available via the ${runtime.services.<service-name>} template string key for helm module services. Note that these are only resolved when deploying/running dependants of the service, so they are not usable for every field.

${runtime.services.<service-name>.version}

The current version of the service.

Example:

my-variable: ${runtime.services.my-service.version}

Task Outputs

The following keys are available via the ${runtime.tasks.<task-name>} template string key for helm module tasks. Note that these are only resolved when deploying/running dependants of the task, so they are not usable for every field.

${runtime.tasks.<task-name>.version}

The current version of the task.

Example:

my-variable: ${runtime.tasks.my-tasks.version}

${runtime.tasks.<task-name>.outputs.log}

The full log from the executed task. (Pro-tip: Make it machine readable so it can be parsed by dependant tasks and services!)
