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.

# 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/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 `Γ¬nclude` 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/using-garden/configuration-overview#including-excluding-files-and-directories)

#
# Unlike the `modules.exclude` field in the project config, the filters here have _no effect_ on which files and

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 Γ¬nclude to [].

Type

Required

array[posixPath]

No

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.

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.

Type

Required

object

No

serviceResource.kind

​serviceResource > kind

The type of Kubernetes resource to sync files to.

Type

Allowed Values

Required

string

"Deployment", "DaemonSet", "StatefulSet"

Type

Required

string

No

serviceResource.podSelector

​serviceResource > podSelector

Type

Required

object

No

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. ''. 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.

Type

Required

string

No

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.

Type

Required

string

No

Example:

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

serviceResource.hotReloadArgs[]

​serviceResource > hotReloadArgs

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.
