exec

Description

A simple module for executing commands in your shell. This can be a useful escape hatch if no other module type fits your needs, and you just need to execute something (as opposed to deploy it, track its status etc.).

By default, the exec module type executes the commands in the Garden build directory (under .garden/build/). By setting local: true, the commands are executed in the module source directory instead.

Note that Garden does not sync the source code for local exec modules into the Garden build directory. This means that include/exclude filters and ignore files are not applied to local exec modules, as the filtering is done during the sync.

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.

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

# 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

#
# Note that you can also _exclude_ files using the `exclude` field or by placing `.gardenignore` files in your source

    - build

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.

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.

This can be handy when you only need certain services for specific environments, e.g. only for development.

Disabling a service means that it will not be deployed, 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 service's outputs (i.e. runtime outputs) will fail to resolve when the service is disabled, so you need to make sure to provide alternate values for those if you're using them, using conditional expressions.

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

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

The name of the module.

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

The local path of the module.

Example:

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

${modules.<module-name>.var.*}

A map of all variables defined in the module.

${modules.<module-name>.var.<variable-name>}

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

The current version of the module.

Example:

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

Service Outputs

The following keys are available via the ${runtime.services.<service-name>} template string key for exec 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 exec 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!)
