Description

The [runners.docker] section have extra_hosts option to configure hosts file.

https://gitlab.com/gitlab-org/gitlab-runner/blob/master/docs/configuration/advanced-configuration.md#the-runnersdocker-section extra_hosts specify hosts that should be defined in a container environment

kubernets has HostAliases to do same thing:

https://kubernetes.io/docs/concepts/services-networking/add-entries-to-pod-etc-hosts-with-host-aliases/

  hostAliases:
  - ip: "127.0.0.1"
    hostnames:
    - "foo.local"
    - "bar.local"
  - ip: "10.1.2.3"
    hostnames:
    - "foo.remote"
    - "bar.remote"

I'm using /etc/hosts to resolve my gitlab host name, and encounter Couldn't resolve host 'gitlab.myhost.com'
