I was trying to test my recent docker install on Debian 9 but the following error appeared:
root@gsdpuma:~# docker run hello-world Unable to find image 'hello-world:latest' locally docker: Error response from daemon: Get https://registry-1.docker.io/v2/: dial tcp: lookup registry-1.docker.io on 126.96.36.199:53: no such host. See 'docker run --help'.
I had clear it was related to our corporate proxy and I was focused on that.
I’ve tried searching for the error but it had multiple solutions, reading the comments I’ve started digging in the filesystem looking for any docker related file, and I found this one:
/etc/systemd/system/multi-user.target.wants/docker.service #which is just a symlink to: lrwxrwxrwx 1 root root 34 Feb 10 14:53 docker.service -> /lib/systemd/system/docker.service
And added this on the file under the [Service] section:
[Service] #proxy added by mortiz Environment=HTTP_PROXY=http://12345.66.777:1234
After that restarted docker:
root@grrrrrr:/etc/systemd/system# service docker restart
Executed docker info to see that the proxy had been loaded correctly:

And I succeeded running the test:
