Docker Login Error: No Such Host

Hey there, my gitlab-ci.yaml attempts to establish a connection to the project’s docker image registry in order that it can then build and push an image to the registry. Howver, when the pipeline runs I get the following error:

 $ docker login -u gitlab-ci-token -p $CI_JOB_TOKEN $CI_REGISTRY
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
Error response from daemon: Get https://my.gitlab.server:1234/v2/: dial tcp: lookup my.gitlab.server on no such host
ERROR: Job failed: exit code 1

I tried putting a ping to my.gitlab.server in to my gitlab-ci.yaml to test, and it was able to successfully hit my server so I don’t know why docker is unable to resolve the hostname.

This problem has been solved…my runner was hitting an device on the network which was lacking an entry for the gitlab server in /etc/hosts and was therefore unable to resolve the hostname.
