What I want should be relatively simple:
Prerequisites:
- Spring Boot project with Gradle build file (already generated from start.spring.io)
- version in gradle.properties, with snapshot suffix (ex: 1.0.1-SNAPSHOT)
In the Gitlab CI pipeline:
using
./gradlew clean build release publish
build the jar myapp-1.0.1.jar, and push it to the Gitlab package registry
- extract the release version into a variable
- build the Docker container with the released jar (not the SNAPSHOT)
- tag the Docker container with the release version obtained before
- push the Docker container to the Docker registry
I have the prerequisites. I can release the project and I get the non-snapshot jar, but when I try to publish, it publishes the SNAPSHOT jar (if the release was 1.0.1, 1.0.2-SNAPSHOT is the jar pushed to the registry).
I can push the Docker container to the registry, but not sure how to go about for the tagging.
