To release a new version

Build in the docker image (make sure you have Docker installed!)

Set the version to the next semantic version after the version posted at our co-op cloud's packages site under "mapbattle":

version=<specify-version>
docker build --platform linux/amd64 -t git.coopcloud.tech/rtm/mapbattle:$version .

Push the image to gitea registery

Check out this documentation for how to login with gitea registery.

# If not in the same terminal session, rerun `version=...` line from last step
docker push git.coopcloud.tech/rtm/mapbattle:$version

At our co-op cloud's packages site, click on "mapbattle" and check that the version mentioned is the version you specified!
