# Builds the Docker image and pushes it to Gitea's built-in container registry
|
|
# on every push to main. Tags each build as :latest and :<commit-sha>.
|
|
#
|
|
# PREREQUISITES on your Gitea instance:
|
|
# 1. Actions must be enabled (app.ini: [actions] ENABLED = true) and at least
|
|
# one act_runner registered.
|
|
# 2. The runner must be able to build images. act_runner needs access to a
|
|
# Docker daemon — either run the runner with the host Docker socket mounted
|
|
# (-v /var/run/docker.sock:/var/run/docker.sock) or in docker-in-docker mode.
|
|
# 3. The Package Registry must be enabled (it is by default).
|
|
#
|
|
# TOKEN: the workflow tries the auto-injected GITHUB_TOKEN first. If your Gitea
|
|
# version does not grant it package-write scope, create a Personal Access Token
|
|
# with "write:package" scope and add it as a repository secret named
|
|
# REGISTRY_TOKEN (Repo > Settings > Actions > Secrets).
