The only way to interact with it is using talosctl (no ssh, very minimal console, etc.) It is pretty slim and designed only to use k8s. Ubuntu on the other hand is general purpose that can be made to use k8s.
Basically the idea being that your nodes are also cattle.
It’s very interesting. I’m debating moving from fedora coreos to it. About to spin up a test cluster whenever I have free time.
Keycloak is very much lighter actually. Can run under half a gig ram whereas authentik uses about 1GB.
Authelia is king though in running with just about 30MB of ram.
