Hi Team, when I run but got some error:

I already set proxy

$sudo systemctl show --property=Environment docker
Environment=HTTP_PROXY=http://192.168.10.233:7890 HTTPS_PROXY=http://192.168.10.233:7890

When I pull the image manually it succeeds.

$docker pull containrrr/watchtower:latest
latest: Pulling from containrrr/watchtower
Digest: sha256:6dd50763bbd632a83cb154d5451700530d1e44200b268a4e9488fefdfcf2b038
Status: Image is up to date for containrrr/watchtower:latest
docker.io/containrrr/watchtower:latest

It looks like watchtower is not using the proxy config?

[iarthit]

me too，May I ask how to solve this

[Seriainme]

docker run -d --name watchtower -v /var/run/docker.sock:/var/run/docker.sock -e DOCKER_REGISTRY_MIRROR=https://register.librax.org containrrr/watchtower -i 60

I encountered the same issue.I restarted the wathchtower container using the command above with a setting on parameter DOCKER_REGISTRY_MIRROR. ck if https://register.librax.org works for you without proxy.if not ,change it to some other mirror domain.

@Seriainme 嘿哥们，我加上了DOCKER_REGISTRY_MIRROR变量，不知道为啥容器的镜像地址还是https://index.docker.io/v2吗？很奇怪

试试删掉本地镜像重新pull 再run呢？
还有观察下你监控的运行中的镜像是否有更新到最新版本，有时候日志可能是错的，你看容器的运行结果就行了。
