Feature Summary

It seems like there is a lot of folks trying to find a workaround to override hosts entries. I've been trying lots of different things with ansible-builder. After working several hours on this I finally found how to do it.

It might be a good idea to document how to do this or possibly add a configuration in the UI beside customizing the pod spec override

References: https://kubernetes.io/docs/tasks/network/customize-hosts-file-for-pods/

I've been able to use the following in the Pod spec override which works great.

spec:
hostAliases:

• ip: "127.0.0.1"
  hostnames:
  • "foo.local"

Select the relevant components

• UI
• API
• Docs
• Collection
• CLI
• Other

Steps to reproduce

Glad to see that you find a solution to the problem, this might be the more relevant link to the Kubernetes doc https://kubernetes.io/docs/tasks/network/customize-hosts-file-for-pods/#adding-additional-entries-with-hostaliases

gonna change this to a docs issue, if you are looking to contribute to the doc, contribution are definitely welcome

@smalenfant - Can you send me links to the documentation you looked at that you expected to have this information, but lacked? It will give me a better idea where readers are looking for this information so I can be sure it gets referenced there.
