手动的更新容器
# == docker stop AAA; docker rm AAA docker rm -f <CONTAINER> ; \ docker pull <IMAGE>; \ docker run <ARG> ... <IMAGE>
使用WatchTower
# 自动更新所有容器，包括watchtower自己
docker run -d \
--name watchtower \
-v /var/run/docker.sock:/var/run/docker.sock \
containrrr/watchtower
# --cleanup, 自动清除老旧文件
# --interval 3600 每3600秒自动检查更新，或者用cron格式，每天凌晨 2 点检查一次更新:
# --schedule "0 0 2 * * *"
# 或者只运行一次
# --run-once
docker run -d \
--name watchtower \
--restart unless-stopped \
-v /var/run/docker.sock:/var/run/docker.sock \
containrrr/watchtower \
--cleanup \
--interval 3600 \
nginx redis <CONTAINER-A> <CONTAINER-B>我采用的标准做法
# check every container every hour; use shanghai timezone;
docker rm -f watchtower; docker pull containrrr/watchtower
docker run -d \
--name watchtower \
--restart unless-stopped \
-e TZ=Asia/Shanghai \
-v /var/run/docker.sock:/var/run/docker.sock \
containrrr/watchtower \
--cleanup \
--interval 3600
# run once
docker rm -f watchtower; docker pull containrrr/watchtower
docker run -d \
--name watchtower \
--restart unless-stopped \
-v /var/run/docker.sock:/var/run/docker.sock \
containrrr/watchtower \
--cleanup \
--run-once \
