Module Template Configuration

Below is the schema reference for ModuleTemplate configuration files. To learn more about module templates, see the Module Templates guide.

The reference is divided into two sections:

YAML Schema contains the config YAML schema
Configuration keys describes each individual schema key for the configuration files.

Also check out the templated module type reference.

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: ModuleTemplate

# The name of the template.
name:

# Path to a JSON schema file describing the expected inputs for the template. Must be an object schema. If none is
# provided, no inputs will be accepted and an error thrown if attempting to do so.
inputsSchemaPath:

# A list of modules this template will output. The schema for each is the same as when you create modules normally in
# configuration files, with the addition of a `path` field, which allows you to specify a sub-directory to set as the
# module root.
#
# In addition to any template strings you can normally use for modules (see [the
# reference](./template-strings/modules.md)), you can reference the inputs described by the inputs schema for the
# template, using ${inputs.*} template strings, as well as ${parent.name} and ${template.name}, to reference the name
# of the module using the template, and the name of the template itself, respectively. This also applies to file
# contents specified under the `files` key.
#
# **Important: Make sure you use templates for any identifiers that must be unique, such as module names, service
# names and task names. Otherwise you'll inevitably run into configuration errors. The module names can reference the
# ${inputs.*}, ${parent.name} and ${template.name} keys. Other identifiers can also reference those, plus any other
# keys available for module templates (see [the module context reference](./template-strings/modules.md)).**
modules:
  - # 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.
    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
