Description

Specify one or more Kubernetes manifests to deploy.

You can either (or both) specify the manifests as part of the garden.yml configuration, or you can refer to one or more files with existing manifests.

Note that if you include the manifests in the garden.yml file, you can use template strings to interpolate values into the manifests.

If you need more advanced templating features you can use the helm module type.

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.

kubernetes 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:

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, Garden automatically sets `include` to equal the
# `files` directive so that only the Kubernetes manifests get included.
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:

# The names of any services that this service depends on at runtime, and the names of any tasks that should be
# executed before this service is deployed.
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.

  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.

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 guidearrow-up-right for details.

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

If neither include nor exclude is set, Garden automatically sets include to equal the files directive so that only the Kubernetes manifests get included.

Type
Required

array[posixPath]

No

Example:

hashtag
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 guidearrow-up-right 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.

Type
Required

array[posixPath]

No

Example:

hashtag
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.

Type
Required

gitUrl | string

No

Example:

hashtag
allowPublish

When false, disables pushing this module to remote registries.

Type
Default
Required

boolean

No

hashtag
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.

Type
Default
Required

array[object]

[]

No

hashtag
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.

Type
Required

posixPath

No

hashtag
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.

Type
Required

posixPath

Yes

hashtag
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.

Type
Default
Required

boolean

true

No

hashtag
generateFiles[].value

generateFiles > value

The desired file contents as a string.

Type
Required

string

No

hashtag
variables

Type
Required

object

No

hashtag
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 dotenvarrow-up-right.

  • .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).

Type

Type
Required

string

No

hashtag
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 guidearrow-up-right for more information.

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.
