This repo is responsible for creating the confluence docker image used for our on-prem confluence.
There's not a lot going on in repo itself other than defining a Dockerfile and gitlab-ci.yml file for the CI/CD pipeline.
To build an image for confluence, simply trigger a new run of the default pipeline for this repo via the GitLab UI
Set a variable DEFAULT_RELEASE_TAG to configure the image version to build.
Ensure you only use semVer format for the DEFAULT_RELEASE_TAG variable, or simply leave it unset to run a build against whatever image is currently present at the latest tag from the upstream Docker Hub repo
The resulting new image will be automatically saved into this Project's Container Registry and should be pullable with Docker CLI from there.
