Docker in Docker with gradle

Docker in docker with Gradle. Used for CI.

Usage

1. Trivial: If you do not want/need to create your own special gradle-jdk combo, feel free to grab any of the images that we have created and pushed over the years here https://hub.docker.com/r/dtforce/dind-gradle/tags

2. Easy (still): If none of our combos suit your needs, find the base image with Gradle, OS and JDK combo you would like to use here https://hub.docker.com/_/gradle/ & see the Howto section bellow.

Howto (with example)

Example based on Gradle 8.10.2 with Alpine Linux and JDK 17

1. Touch the Dockerfile in this repo accordingly (i.e. use gradle:8.10.2-jdk17-alpine in FROM)

2. Build and push (change the dtforce for your own dockerhub organization)

docker build . -t dtforce/dind-gradle:v8.10.2-alp-jdk17-py
docker push dtforce/dind-gradle:v8.10.2-alp-jdk17-py

3. Use the built image in you CI/CD pipeline and enjoy
