jib-container

Modules are deprecated and will be removed in version 0.14. Please use action-based configuration instead. See the 0.12 to Bonsai migration guide for details.

Description

Extends the container 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 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 actions.

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 types, jib-container builds are done from the source directory instead of the build staging directory, because of how Java projects are often laid out across a repository. This means build dependency 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 Build 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.

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

# 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

# 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/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 guide](https://docs.garden.io/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.
    targetPath:

    # 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:

# Specify build arguments to use when building the container image.

platforms:

# Secret values that can be mounted in the Dockerfile, but do not become part of the image filesystem or image
# manifest. This is useful e.g. for private registry auth tokens.
#
# Build arguments and environment variables are inappropriate for secrets, as they persist in the final image.
#
# The secret can later be consumed in the Dockerfile like so:

# See also https://docs.docker.com/build/building/secrets/
secrets:

# Specify the image name for the container. Should be a valid Docker image identifier. If specified and the module

        # http://my-service:8090/some-endpoint.
        # It is common to use port 80, the default port number, so that you can call the service directly with
        # http://my-service/some-endpoint.

Configuration Keys

kind

type

The type of this module.

Example:

type: "container"

Example:

name: "my-sweet-module"

build

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

build.dependencies[]

build > dependencies

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

Example:

build:
  ...
  dependencies:
    - name: some-other-module-name

build.dependencies[].name

build > dependencies > name

Module name to build ahead of this module.

build.dependencies[].copy[]

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

build.dependencies[].copy[].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

build > timeout

Maximum time in seconds to wait for build to finish.

build.projectType

build > projectType

The type of project to build. Defaults to auto-detecting between gradle and maven (based on which files/directories are found in the action root), but in some cases you may need to specify it.

build.jdkVersion

build > jdkVersion

The JDK version to use.

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.

The value will be used as JAVA_HOME environment variable for Gradle and Maven.

Example:

build:
  ...
  jdkPath: "${local.env.JAVA_HOME}"

build.dockerBuild

build > dockerBuild

Build the image and push to a local Docker daemon (i.e. use the jib:dockerBuild / jibDockerBuild target).

build.tarOnly

build > tarOnly

Don't load or push the resulting image to a Docker daemon or registry, only build it as a tar file.

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.

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

build.mavenPhases[]

build > mavenPhases

Defines the Maven phases to be executed during the Garden build step.

build.mavendPath

build > mavendPath

Defines the location of the custom executable Maven Daemon binary.

If not provided, then Maven Daemon 0.9.0 will be downloaded and used.

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

build.concurrentMavenBuilds

build > concurrentMavenBuilds

Experimental: this is an experimental feature and the API might change in the future.

[EXPERIMENTAL] Enable/disable concurrent Maven and Maven Daemon builds.

Note! Concurrent builds can be unstable. This option is disabled by default. This option must be configured for each Build action individually.

build.extraFlags[]

build > extraFlags

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

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 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 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:

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 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

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

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:

  • .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.

  • .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).
