hadolint

Description

Runs hadolint on the specified Dockerfile.

Note: In most cases, you'll let the 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 for details on how to configure it.

Below is the full schema reference. For an introduction to configuring Garden modules, please look at our .

The contains the complete YAML schema, and the describes each schema key.

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

Complete YAML Schema

The values in the schema below are the default values.

Configuration Keys

kind

type

The type of this module.

Example:

name

The name of this module.

Example:

build

Specify how to build the module. Note that plugins may define additional keys on this object.

build.dependencies[]

A list of modules that must be built before this module is built.

Example:

build.dependencies[].name

Module name to build ahead of this module.

build.dependencies[].copy[]

Specify one or more files or directories to copy from the built dependency to this module.

build.dependencies[].copy[].source

POSIX-style path or filename of the directory or file(s) to copy to the target.

build.dependencies[].copy[].target

POSIX-style path or filename to copy the directory or file(s), relative to the build directory. Defaults to the same as source path.

build.timeout

Maximum time in seconds to wait for build to finish.

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).

Note: This maps to the buildAtSource option in this module's generated Build action (if any).

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 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.

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.

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

Example:

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.

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.

Example:

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:

allowPublish

When false, disables pushing this module to remote registries via the publish command.

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

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.

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

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

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:

• .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.

• .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).

Example:

dockerfilePath

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

Outputs

Module Outputs

The following keys are available via the ${modules.<module-name>} template string key for hadolint modules.

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

The build path of the module.

Example:

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

The name of the module.

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

The source path of the module.

Example:

${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:

Service Outputs

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

Task Outputs

The following keys are available via the ${runtime.tasks.<task-name>} template string key for hadolint 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.
