Docker Images for Solr
======================

Solr docker images are built using Palantir's Docker Gradle plugin, https://github.com/palantir/gradle-docker.

Common Inputs
-------------

The docker image and its 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

Building
--------

In order to build the Solr Docker image, run:

gradlew docker

The docker build task accepts the following inputs, in addition to the common inputs listed above:

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

Testing
-------

To test the docker image, run:

gradlew dockerTest

If a custom docker image name was used, via one of the common inputs described above, then the same input must be used while testing.

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.

gradlew testDocker --tests create_core,demo
gradlew testDocker --ignore demo-tini,initdb
