Not sure if this is a bug or just me being to blind to see...

On Pod templates UI I'm using the Raw YAML field with the idea of making a hosts entry within the containers:

apiVersion: v1
kind: Pod
spec:
  hostAliases:
  - ip: "127.0.0.1"
    hostnames:
    - "foo.local" 

..but this only seems to work when Yaml merge strategy is set to Override.

As we've defined quite a lot of Pod templates also inheriting from each other Override is not an option.

I've also tried to workaround by directly modifying /etc/hosts via the container's entrypoint with the help of the Command to run field like this:

/bin/sh -c "echo 127.0.0.1 foo.local" >> /etc/hosts"

...unfortunately that also doesn't work as /etc/hosts is managed by Kubernetes and above made entry gets reverted.

Any help is highly appreciated.

Thanks,
Chris
