隨著docker使用的愈來愈多

更新管理這件事也變的重要

找到watchtower這個工具還滿方便使用的

部署方式如下

docker run -d --restart=always \

--name watchtower \

-v /var/run/docker.sock:/var/run/docker.sock \

containrrr/watchtower \

--cleanup --remove-volumes \

--interval 86400

預設檢查時間是 86400 秒可視需求調整

如果需要只email通知而不更新

docker run -d --restart=always \
