Docker 带有 Nexus 的注册表：503 服务不可用

Question

I want to use a Nexus as private registry to push docker image but I'm not able to login

When I try this:

docker login xxx.xxx.com:8500

I have this message:

Error response from daemon: login attempt to http://xxx.xxx.com:8500/v2/ failed with status: 503 Service Unavailable

I set up my /etc/docker/daemon.json like this:

{
  "insecure-registries": [
    "xxx.xxx.com:8500",
    "xxx.xxx.com:8501"
  ]
}

And when I try this:

curl http://xxx.xxx.com:8500/v2/_catalog

I have a response:

{"repositories":[]}

Thanks for your help

Answer 1

I solved my issue with modifying the /etc/sysconfig/docker file. I added NO_PROXY="xxx.xxx.com" then exec "systemctl restart docker" and it worked.
