jib-container

Description

Extends the container module type to build the image with Jib. Use this to efficiently build container images for Java services. Check out the jib example to see it in action.

The image is always built locally, directly from the module source directory (see the note on that below), before shipping the container image to the right place. You can set build.tarOnly: true to only build the image as a tarball.

By default (and when not using remote building), the image is pushed to the local Docker daemon, to match the behavior of and stay compatible with normal container modules.

When using remote building with the kubernetes provider, the image is synced to the cluster (where individual layers are cached) and then pushed to the deployment registry from there. This is to make sure any registry auth works seamlessly and exactly like for normal Docker image builds.

Please consult the Jib documentation for how to configure Jib in your Gradle or Maven project.

To provide additional arguments to Gradle/Maven when building, you can set the extraFlags field.

Important note: Unlike many other module types, jib modules are built from the module source directory instead of the build staging directory, because of how Java projects are often laid out across a repository. This means build.dependencies[].copy directives are effectively ignored, and any include/exclude statements and .gardenignore files will not impact the build result. Note that you should still configure includes, excludes and/or a .gardenignore to tell Garden which files to consider as part of the module version hash, to correctly detect whether a new build is required.

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.

jib-container 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/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.
#
# If neither `include` nor `exclude` is set, and the module has a Dockerfile, Garden
# will parse the Dockerfile and automatically set `include` to match the files and
# folders added to the Docker image (via the `COPY` and `ADD` directives in the Dockerfile).
#
# If neither `include` nor `exclude` is set, and the module
# specifies a remote image, Garden automatically sets `include` 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

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

variables:

# Specify a path (relative to the module root) to a file containing variables, that we apply on top of the

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

The chosen version will be downloaded by Garden and used to define JAVA_HOME environment variable for Gradle and Maven.

To use an arbitrary JDK distribution, please use the jdkPath configuration option.

build.jdkPath

build > jdkPath

The JDK home path. This always overrides the JDK defined in jdkVersion.

build.tarFormat

build > tarFormat

Specify the image format in the resulting tar file. Only used if tarOnly: true.

build.gradlePath

build > gradlePath

Defines the location of the custom executable Gradle binary.

If not provided, then the Gradle binary available in the working directory will be used. If no Gradle binary found in the working dir, then Gradle 7.5.1 will be downloaded and used.

Note! Either jdkVersion or jdkPath will be used to define JAVA_HOME environment variable for the custom Gradle. To ensure a system JDK usage, please set jdkPath to ${local.env.JAVA_HOME}.

build.mavenPath

build > mavenPath

Defines the location of the custom executable Maven binary.

If not provided, then Maven 3.8.8 will be downloaded and used.

build.extraFlags[]

build > extraFlags

Specify extra flags to pass to maven/gradle when building the container image.

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.

If neither include nor exclude is set, and the module has a Dockerfile, Garden will parse the Dockerfile and automatically set include to match the files and folders added to the Docker image (via the COPY and ADD directives in the Dockerfile).

If neither include nor exclude is set, and the module specifies a remote image, Garden automatically sets include to [].

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.

  • .yaml/.yml - YAML. The file must consist of a YAML document, which must be a map (dictionary). Keys may contain any value type.

  • .json - JSON. Must contain a single JSON object (not an array).

NOTE: The default varfile format will change 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:

varfile: "my-module.env"

buildArgs

Specify build arguments to use when building the container image.

Note: Garden will always set a GARDEN_MODULE_VERSION argument with the module version at build time.

extraFlags[]

Specify extra flags to use when building the container image. Note that arguments may not be portable across implementations.

image

Specify the image name for the container. Should be a valid Docker image identifier. If specified and the module does not contain a Dockerfile, this image will be used to deploy services for this module. If specified and the module does contain a Dockerfile, this identifier is used when pushing the built image.

hotReload

Specifies which files or directories to sync to which paths inside the running containers of hot reload-enabled services when those files or directories are modified. Applies to this module's services, and to services with this module as their sourceModule.

hotReload.sync[]

hotReload > sync

Specify one or more source files or directories to automatically sync into the running container.

hotReload.sync[].source

hotReload > sync > source

POSIX-style path of the directory to sync to the target, relative to the module's top-level directory. Must be a relative path. Defaults to the module's top-level directory if no value is provided.

Example:

hotReload:
  ...
  sync:
    - source: "src"

hotReload.sync[].target

hotReload > sync > target

POSIX-style absolute path to sync the directory to inside the container. The root path (i.e. "/") is not allowed.

Example:

hotReload:
  ...
  sync:
    - target: "/app/src"

hotReload.postSyncCommand[]

hotReload > postSyncCommand

An optional command to run inside the container after syncing.

Example:

hotReload:
  ...
  postSyncCommand:
    - rebuild-static-assets.sh

dockerfile

POSIX-style name of Dockerfile, relative to module root.

services[]

A list of services to deploy from this container module.

services[].name

services > name

Valid RFC1035/RFC1123 (DNS) label (may contain lowercase letters, numbers and dashes, must start with a letter, and cannot end with a dash), cannot contain consecutive dashes or start with garden, or be longer than 63 characters.

services[].dependencies[]

services > dependencies

The names of any services that this service depends on at runtime, and the names of any tasks that should be executed before this service is deployed.
