docker: Error response from daemon: Get https://registry-1.docker.io/v2/: Service Unavailable. IN DOCKER , MAC

Solution 1:

Here are few suggestions:

1. Try restarting your Docker service.

2. Check your network connections. For example by the following shell commands:

   </dev/tcp/registry-1.docker.io/443 && echo Works || echo Problem
   curl https://registry-1.docker.io/v2/ && echo Works || echo Problem
   

3. Check your proxy settings (e.g. in /etc/default/docker).

If above won't help, this could be a temporary issue with the Docker services (as per Service Unavailable).

I had this problem for past days, it just worked after that.

You can consider raising the issue at docker/hub-feedback repo, check at, Docker Community Forums, or contact Docker Support directly.

Solution 2:

I tried running on Windows, and got this problem after an update. I tried restarting the docker service as well as my pc, but nothing worked.

When running:

curl https://registry-1.docker.io/v2/ && echo Works

I got back:

{"errors":[{"code":"UNAUTHORIZED","message":"authentication required","detail":null}]}
Works

Eventually, I tried: https://github.com/moby/moby/issues/22635#issuecomment-284956961

By changing the fixed address to 8.8.8.8:

Which worked for me! I still got the unauthorized message for curl https://registry-1.docker.io/v2/ but I managed to pull images from docker hub.

Solution 3:

docker logout
docker login

This might solve your problem

Solution 4:

For me I had this issue when I first installed Docker and ran

docker run hello-world

I got an authentication required error when I ran

curl https://registry-1.docker.io/v2/ && echo Works

All I needed to do was to restart my MacOS and then run the command again, it just started pulling the image and i got the message

Hello from Docker!
This message shows that your installation appears to be working correctly.

Solution 5:

It's clearly a proxy issue: docker proxies https connections to the wrong place. Bear in mind that docker proxy settings may be different from the operating system (and curl) ones. Here's how I managed to solve the issue:

First of all, find out where are you proxying your docker https requests:

# docker info | grep Proxy
Http Proxy: http://<my.proxy.server>:8080
Https Proxy: https://<my.proxy.server>:8080
No Proxy: localhost,127.0.0.1

and double check your https settings.

In my case, I realized that the "Https proxy" was set to https://... instead of http://..., so I corrected it in /etc/sysconfig/docker file (I'm using RHEL7) and, after a docker restart with:

# systemctl restart docker

the proxy variable shows up succesfully updated:

# docker info | grep Proxy
Http Proxy: http://<my.proxy.server>:8080
Https Proxy: http://<my.proxy.server>:8080
No Proxy: localhost,127.0.0.1

and everything works fine :-)
