Example: Jib Multi-Module

Jib is one of the supported builders in Skaffold. It builds Docker and OCI images for your Java applications and is available as plugins for Maven and Gradle.

Sometimes a project is configured to have multiple modules to create several container images. Skaffold can work with Jib to build these containers as required.

The way you configure it in skaffold.yaml is the following build stanza:

build:
     artifacts:
     - image: skaffold-jib-1
       # context is the root of the multi-module project
       context: .
       jib:
          # project is the location relative to the artifact `context`
          # For Maven, this is either the path relative to the artifact's
          # `context`, or `:artifactId` or `groupId:artifactId`.
          # For Gradle, this is the project name (defaults to the
          # directory name).
          project: moduleLocation
     - image: skaffold-jib-2
       context: .
       jib:
          project: :artifactId

There are a few caveats:

• The jib-maven-plugin must be either be configured referenced in the root module of the project. This is easily done through a pluginManagement block.

• The artifact modules must have a jib:xxx goal bound to the package phase.
