# Gitea twin of .github/workflows/docker.yml. Gitea runs only .gitea/workflows/ once this

# Publishes to IPCR on watch.nsl.sh instead of ghcr.io:
#   push  ipcr-push-watch.nsl.sh/metadec.eth/<repo>:<tag>   docker login as metadec.eth with the
#         IPCR_PUSH_TOKEN secret (the metadec.eth namespace token from the IPCR dashboard)
#   pull  ipcr-watch.nsl.sh/ipns/metadec.eth/metadec.eth/<repo>:<tag>   anonymous
# The runner's job image (node:22-bookworm) has no docker CLI, so the static one is
# installed first; buildx installs itself. No `type=gha` cache: the runner has none.
