# Woodpecker CI for ZDDC.
#
# Triggers on `zddc-server-v*` tag pushes. Builds the runtime container
# image and publishes it to Codeberg's container registry with channel
# tags that cascade downward, so that pinning to `:stable` always gets
# the most recent stable, `:beta` always tracks the most recent beta-or-
# stable, and `:alpha` always tracks the most recent alpha-or-newer.
#
# Tag conventions
# ---------------
#   zddc-server-vX.Y.Z              → stable release
#   zddc-server-vX.Y.Z-beta.N       → beta release
#   zddc-server-vX.Y.Z-alpha.N      → alpha release
#
# Image tags applied (cascading)
# ------------------------------
#   stable release:   :X.Y.Z         + :stable, :beta, :alpha, :latest
#   beta release:     :X.Y.Z-beta.N  + :beta, :alpha
#   alpha release:    :X.Y.Z-alpha.N + :alpha
#
# `:latest` is kept as an alias for `:stable` (Docker convention).
#
# To enable: in the Woodpecker dashboard at https://ci.codeberg.org →
# repo → Settings → Secrets, add codeberg_user (your Codeberg username)
# and codeberg_token (a personal token with package:write scope from
# https://codeberg.org/user/settings/applications). Restrict both
# secrets to the `tag` event for safety.

    image: docker.io/alpine:3.20
    commands:
      # 1. Assemble zddc/dist/web/ from the landing + archive built outputs.
      #    build.sh now skips the (host-side) podman binary build when
      #    podman is absent, which is the case in CI — the runtime
      #    container image's own builder stage produces linux/amd64.
      - sh build.sh
      # 2. Compute the image tags. Grammar:
      #    zddc-server-vX.Y.Z              → stable
      #    zddc-server-vX.Y.Z-alpha.N      → alpha (cascade: alpha)
      #    zddc-server-vX.Y.Z-beta.N       → beta  (cascade: beta, alpha)
      #    Anything else is rejected by the `when:` filter; nothing to
      #    handle here.
