# Woodpecker CI Pipeline
#
# Шаги:
#   1. docker-build      — сборка и push образа при push в main
#   2. docker-build-tag  — сборка и push образа при git tag
#   3. deploy            — деплой на сервер на агенте role=work_woodpecker
#
# Секреты (Settings -> Secrets):
#   forgejo_host      — хост registry
#   forgejo_image     — полный путь образа
#   forgejo_username  — пользователь registry
#   forgejo_token     — токен для push
