Yeeahh... I'm thinking (hoping) he means an alternative LDAP/IDP, like Keycloak or Authentik..? Wanting to reduce reliance on Windows = kicking AD to the curb, too.
There is Samba AD but that will very much not run in kubernetes
I'm fooling around with a few samba AD docker containers. I ask because I've phased almost everything else out of my lab environment.
The problem with Samba AD in a container or Samba in container is that Samba isn't designed to be run in a temporary environment. You could run it in a LXC container but anything beyond that will break things in the short or long term.
I figured you could get around some of the storage limitations with something like persistent volume claims. I'm testing it out at the moment. I am a big fan of LXC.
I see a few people have created docker Samba Containers and I'm giving them a whirl. Can't say much for stability but I think it's an interesting experiment.
I know in the past smb server didn't work in LXC containers because certain kernel modules caused conflicts.
A man can dream.
If you manage to create persistent containers how are you going to update them down the road? Like I have said previously, Samba isn't designed in a way that allows for effectively hot swapping system components.
It seems like it would better to create a VM template and then setup a fail over cluster. Just make sure you have a time server somewhere on the network.
If you are dead set on containers you could try LDAP in a container. I just don't think active directory was built for Linux containerization.
There are a few applications out there that I don't fully understand the deployment of but seem to work in containers.
Typically the storage is mounted outside of the container and passed through in the compose file for docker. This allows your data to be persistent. Ideally you would also want those to reside in a file system that can easily be snapshot like ZFS. When you pull down a new docker container, it should just remount the same location and begin to run.
Or at least that's how I'd imagine it would run. I feel like one would run into the same challenges people have running databases persistently in containers.
I'm also interested in these alternatives!
