Does it not support container registries " jihulab.com" and "aliyuncs.com"?

[wei-z-git]

Hello,
I`m using container registries jihulab(Gitlab provider in China) and aliyun CR, and I`m sure I have docker login those two hosts, but it still can`t update containers and show errors maybe related to authorization.
But it`s ok for me when I using dockerhub.

• Command:

docker run --detach  --name watchtower -v /root/.docker/config.json:/config.json --volume /var/run/docker.sock:/var/run/docker.sock     containrrr/watchtower qiuqiu_store_latest -i 5 --debug

• config.json:

{
        "auths": {
                "https://index.docker.io/v1/": {
                        "auth": "xxx"
                },
                "registry.cn-hangzhou.aliyuncs.com": {
                        "auth": "xxx"
                },

                }
        }
}

I`d like to know if it means these two registries are not supported by watchtower?
Thanks

No, not necessarily. It just says that the repository doesn't support HEAD requests, which are just used to check for updates without pulling images. It falls back to doing image pulls and concluded that there were no new images in the log posted.

Understood, I was wrong that I thought watchtower can also help update image tag(like 1.0.0 to 2.0.0). Actually it can only update containers of same tag with different image ID.
Thank you! @piksel

Well, it respects the tags, so if you want to use the latest patch, use v1.0, the latest minor v1, or the latest major use latest.
