Docker Images for Solr
======================
In order to build and tag a Solr docker image, merely run the following command:
gradlew docker
This calls the dockerBuild and dockerTag tasks, which have inputs that are described below.
Building
--------
In order to build the Solr Docker image, run:
gradlew dockerBuild
The docker build task accepts the following inputs, all accepted via both Environment Variables and Gradle Properties.
Base Docker Image: (The docker image used for the "FROM" in the Solr Dockerfile)
Default: "openjdk:11-jre-slim"
EnvVar: SOLR_DOCKER_BASE_IMAGE
Gradle Property: -Psolr.docker.baseImage
Github URL or Mirror: (The URL of github or a mirror of github releases. This is of use when building the docker image behind a firewall that does not have access to external Github.)
Default: "github.com"
EnvVar: SOLR_DOCKER_GITHUB_URL
Gradle Property: -Psolr.docker.githubUrl
Tagging and Pushing
-------
To tag the docker image, run the following command.
This will also ensure that the docker image has been built as per the inputs detailed above.
gradlew dockerTag
And to push the image with the given tag, run the following command.
Gradle will ensure that the docker image is built and tagged as the inputs describe before being pushed.
gradlew dockerPush
The docker image tag can be customized via the following options, all accepted via both Environment Variables and Gradle Properties.
Docker Image Repository:
Default: "apache/solr"
EnvVar: SOLR_DOCKER_IMAGE_REPO
Gradle Property: -Psolr.docker.imageRepo
Docker Image Tag:
Default: the Solr version, e.g. "9.0.0-SNAPSHOT"
EnvVar: SOLR_DOCKER_IMAGE_TAG
Gradle Property: -Psolr.docker.imageTag
Docker Image Name: (Use this to explicitly set a whole image name. If given, the image repo and image version options above are ignored.)
Default: {image_repo}/{image_tag} (both options provided above, with defaults)
EnvVar: SOLR_DOCKER_IMAGE_NAME
Gradle Property: -Psolr.docker.imageName
Testing
-------
To test the docker image, run the following command.
This will also ensure that the docker image has been built as per the inputs detailed above in the "Building" section.
gradlew testDocker
If a docker image build parameters were used during building, then the same inputs must be used while testing.
Otherwise a new docker image will be built for the tests to run with.
You can also specify an explicit list of tests to run, or an explicit list of tests to ignore.
Both inputs are optional, and by default all tests will be run.
Each input tasks a comma separated list of test names.
Run specific tests:
EnvVar: SOLR_DOCKER_TESTS_INCLUDE
Gradle Property: -Psolr.docker.tests.include
Exclude specific tests:
EnvVar: SOLR_DOCKER_TESTS_EXCLUDE
Gradle Property: -Psolr.docker.tests.exclude
