Draft: Support list of hosts and IPs that will be injected into the build pod's hosts file

Horatiu Eugen Vlad requested to merge hvlad/gitlab-runner:feature/build_pod_hostaliases into master

What does this MR do?

Support configuration for list of hosts and IPs that will be injected into the build pod's hosts file, introduced with gitlab-org/gitlab-runner!1570 (closed)

Why was this MR needed?

Provide the capability to configure the hostAlias for the build instances started on a kubernetes cluster using the --kubernetes-extra-hosts option of the kubernetes executor.

What's the best way to test this MR?

Try to start a job using k8s runners with extra_hosts configured:

  • the extra hosts should be part of the build pod hostAlias
  • the extra hosts should be injected in /etc/hosts file in the build contianer.

What are the relevant issue numbers?

Add support for gitlab-org/gitlab-runner#2818 (closed)
