Logcollection doesn't come out of the box, and you're kinda on your own to set it up, this article (although a bit dated) shows you what you must go through:
We may be talking about different things, but GP's comment said "unsupported" whereas in kubernetes it's just not part of the control plane offered by kubernetes itself, in exactly the same way that cloud load balancer or even cloud auto-scaling isn't provided by kubernetes itself
Having read the sibling's comment, I think I better understand the situation since Nomad isn't a container orchestrator and thus there isn't one homogeneous place from which _to_ collect the logs, but in any sane k8s setup that's not true since both dockerd and containerd have mechanisms to influence that behavior and k8s is perfectly able, and supports, scheduling per-Node utility plumbing stuff like that without drama
Yes k8s does not provide a out-of-box logging collection solution but since everything is in containers, we can piggyback on Docker or Containerd via deamonset to get all the logs.
Nomad on the other hand support various payload(native exec, exec via chroot, containers, even Firecracker VM by community support), so doing logging collection by end users is trickier.
It worth noting that Nomad UI(a official web admin panel) has log tailing utility built-in so maybe partial work has already been done. The developers may have other concerns.
I like Nomad a lot. It is even more lightweight than k3s and has served my low-budget projects very well.
A little sad to see things are going this way.
