For container orchestration, which is mostly what k8s provides, then you could use docker swarm or nomad.
You could use docker-compose with multiple replicas of the wanted container + a load balancer to divide the load.
In general I don’t think k8s/k3s is needed for hosting lemmy yet, but since I have a setup for k3s, it is easier for me to use it.
I have only 1 container of pictrs running(with no scaling) and are using longhorn for storage, so if the pictrs container switches node, then longhorn handles it for me.

My instance has 2 users. The domain name is endlesstalk.org
I host it on a k3s cluster with 2 nodes.
Is there a way to host with high availability? Or is that a kubernetes feature?
K8s is just a huge abstraction over your clusters, the real question is if the software/containers support HA.
I’ve been meaning to test it for a while now, but have just been running VMs/Docker. Will check it out.
You can definitely have high availibillity without kubernetes, but its easier(For me atleast) with kubernetes.
What HA options exist outside of k8s?

Nice, thanks for the info.
how do you handle the sled state for pictrs with 2 nodes? I’ve been having some trouble with it.
I have only 1 container of pictrs running(with no scaling) and are using longhorn for storage, so if the pictrs container switches node, then longhorn handles it for me.
I see, thanks. What volume(s) are you persisting that way exactly? I mean the internal path that pictrs is using.
The internal path, I’m persisting is
/mnt, but I also use an older version of pictrs(0.3.1). Think the newer version uses a different path.I also needed to add the following for the pictrs container to work correctly.
Thanks a lot!
