# hadolint

{% hint style="warning" %}
Modules are deprecated and will be removed in version `0.14`. Please use [action](https://docs.garden.io/bonsai-0.13/using-garden/actions)-based configuration instead. See the [0.12 to Bonsai migration guide](https://docs.garden.io/bonsai-0.13/guides/migrating-to-bonsai) for details.
{% endhint %}

## Description

Runs `hadolint` on the specified Dockerfile.

> Note: In most cases, you'll let the [provider](https://docs.garden.io/bonsai-0.13/reference/providers/hadolint) create this module type automatically, but you may in some cases want or need to manually specify a Dockerfile to lint.

To configure `hadolint`, you can use `.hadolint.yaml` config files. For each test, we first look for one in the module root. If none is found there, we check the project root, and if none is there we fall back to default configuration. Note that for reasons of portability, we do not fall back to global/user configuration files.

See the [hadolint docs](https://github.com/hadolint/hadolint#configure) for details on how to configure it.

Below is the full schema reference. For an introduction to configuring Garden modules, please look at our [Configuration guide](https://docs.garden.io/bonsai-0.13/using-garden/configuration-overview).

The [first section](#complete-yaml-schema) contains the complete YAML schema, and the [second section](#configuration-keys) describes each schema key.

`hadolint` modules also export values that are available in template strings. See the [Outputs](#outputs) section below for details.

## Complete YAML Schema

The values in the schema below are the default values.

```yaml
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: 600

# If set to true, Garden will run the build command, services, tests, and tasks in the module source directory,
# instead of in the Garden build directory (under .garden/build/<module-name>).
#
# Garden will therefore not stage the build for local modules. This means that include/exclude filters
# and ignore files are not applied to local modules, except to calculate the module/action versions.
#
# If you use use `build.dependencies[].copy` for one or more build dependencies of this module, the copied files
# will be copied to the module source directory (instead of the build directory, as is the default case when
# `local = false`).
#
# Note: This maps to the `buildAtSource` option in this module's generated Build action (if any).
local: false

# 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 build, deployed or run.
#
# 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/bonsai-0.13/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
# guide](https://docs.garden.io/bonsai-0.13/using-garden/configuration-overview#including-excluding-files-and-directories)
# for details.
#
# Unlike the `scan.exclude` field in the project config, the filters here have _no effect_ on which files and
# directories are watched for changes. Use the project `scan.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 via the publish command.
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
    # ConfigTemplate 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.

    # 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:
#
# * `.yaml`/`.yml` - YAML. The file must consist of a YAML document, which must be a map (dictionary). Keys may
# contain any value type. YAML format is used by default.
# * `.env` - Standard "dotenv" format, as defined by [dotenv](https://github.com/motdotla/dotenv#rules).
# * `.json` - JSON. Must contain a single JSON _object_ (not an array).
#
# _NOTE: The default varfile format was changed 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:

# POSIX-style path to a Dockerfile that you want to lint with `hadolint`.

### `local`

If set to true, Garden will run the build command, services, tests, and tasks in the module source directory, instead of in the Garden build directory (under .garden/build/).

Garden will therefore not stage the build for local modules. This means that include/exclude filters and ignore files are not applied to local modules, except to calculate the module/action versions.

If you use use `build.dependencies[].copy` for one or more build dependencies of this module, the copied files will be copied to the module source directory (instead of the build directory, as is the default case when `local = false`).

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 build, deployed or run.

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.

| Type      | Default | Required |

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/bonsai-0.13/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.

| Type               | Required |

Example:

```yaml

### `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](https://docs.garden.io/bonsai-0.13/using-garden/configuration-overview#including-excluding-files-and-directories) for details.

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

| Type               | Required |
| ------------------ | -------- |
| `array[posixPath]` | No       |

| `posixPath` | No       |

### `generateFiles[].targetPath`

[generateFiles](#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).
