Sonic image is not working in Kubernetes

[RomanKlosSecurrency]

Hello,
I have tried to put sonic server in kubernetes. I want my application and sonic server to be located in the same space.
I have got errors pointing me that sonic image does not have some files like /etc/hosts, /etc/hostname, /etc/resolve.conf. Honestly I stopped trying to make it work after that. Exploring the image I saw that no /etc directory is present.

I have tried to build new image from master branch. Got another error on build step:

Because of lack of knowledge I could not resolve it.
Is it possible to create new images with Kubernetes support, so it can just work "from the box" ?

I think there is no problem about k8s.It's only a compile problem? so can I see your DockerFile? it hint your " rustup target add x86_64-unknown-linux-gnu" in your DockerFile. You can also build it prev and Copy the bianry file sonic into the base image which fix your production environment..so if you have problem, we can have a discussion. ps: My English is poor, hope to help you!
