Docker images for cp-base-lite

This repo provides build files for the new base image for Confluent lightweight Docker images. This will build the image cp-base-lite, which is the lighter version of cp-base-new. cub-dub commands aren't supported in this image as Python is not installed. Instead of JDK, the JRE is being installed.

Properties

This project contains a Dockerfile for building cp-base-lite, the common base image for new Confluent lightweight Docker images.

Properties are inherited from a top-level POM. Properties may be overridden on the command line (-Ddocker.registry=testing.example.com:8080/), or in a subproject's POM.

  • docker.skip-build: (Optional) Set to false to include Docker images as part of build. Default is 'false'.
  • docker.skip-test: (Optional) Set to false to include Docker image integration tests as part of the build. Requires Python 2.7, tox. Default is 'true'.
  • docker.registry: (Optional) Specify a registry other than placeholder/. Used as DOCKER_REGISTRY during docker build and testing. Trailing / is required. Defaults to placeholder/.
  • docker.tag: (Optional) Tag for built images. Used as DOCKER_TAG during docker build and testing. Defaults to the value of project.version.
  • docker.upstream-registry: (Optional) Registry to pull base images from. Trailing / is required. Used as DOCKER_UPSTREAM_REGISTRY during docker build. Defaults to the value of docker.registry.
  • docker.upstream-tag: (Optional) Use the given tag when pulling base images. Used as DOCKER_UPSTREAM_TAG during docker build. Defaults to the value of docker.tag.
  • docker.test-registry: (Optional) Registry to pull test dependency images from. Trailing / is required. Used as DOCKER_TEST_REGISTRY during testing. Defaults to the value of docker.upstream-registry.
  • docker.test-tag: (Optional) Use the given tag when pulling test dependency images. Used as DOCKER_TEST_TAG during testing. Defaults to the value of docker.upstream-tag.
  • docker.os_type: (Optional) Specify which operating system to use as the base image by using the Dockerfile with this extension. Valid values are ubi8. Default value is ubi8.
  • docker.skip-security-update-check: (Optional) The Dockerfile.ubi8 will run a security update check. If left to the default (false) and there is a pending security update that is not installed, then the build will fail, enforcing good security practices. If set to true, the check will pass no matter what. NOT ADVISABLE USE AT YOUR OWN RISK. Default value is false.

Build arguments

  • CONFLUENT_VERSION: (Required) Specify the full Confluent Platform release version. Example: 5.4.0
  • See Dockferfile for more.

Building

This project uses maven-assembly-plugin and dockerfile-maven-plugin to build Docker images via Maven.

To build SNAPSHOT images, configure .m2/settings.xml for SNAPSHOT dependencies. These must be available at build time.

mvn clean package -Pdocker -DskipTests # Build local images
