      debug:
        msg: |
          Gitea has been restarted successfully with Redis cache enabled!
          
          Cache configuration:
          - ENABLED: true
          - ADAPTER: redis
          - HOST: redis:6379
          - DB: 0
          
          Gitea should now use Redis for caching, improving performance.
