Deploy Dragonfly with crontab backup with Docker compose

使用docker compose部署dragonfly并设置定时任务备份至本地磁盘

compose file:

version: "3.8"
services:
  dragonfly:
    image: docker.dragonflydb.io/dragonflydb/dragonfly
    ulimits:
      memlock: -1
    ports:
      - TAILSCALE_IP:16379:6379
    # For better performance, consider `host` mode instead `port` to avoid docker NAT.
    # `host` mode is NOT currently supported in Swarm Mode.
    # https://docs.docker.com/compose/compose-file/compose-file-v3/#network_mode
    # network_mode: "host"
    volumes:
      - /zmain/df/data:/data:rwz
    networks:
      - dockge_default
    command:
      - dragonfly
      - --logtostderr
      - --snapshot_cron
      - "*/30 * * * *"
networks:
  dockge_default:
    external: true

注意坑点：

• dragonfly运行时使用的用户是dfly， 如果你进入容器使用id查看可以看到uid:gid是999:999
• 如果遇到save权限问题，在宿主机内对目标目录进行chown -R 999:999 TARGET_FOLDER这样挂载后能识别为dfly:dfly并成功保存
