Last I checked k3s required a min of 512mb of ram, 1gb recommended. Is this not the case?

  Yes it is. Docker's minimum requirement is 512mb with 2gb recommended. Containerd + k8s is almost the same requirements.

    Interesting, I wasn't actually aware of that. Checking my running server with 1024mb of RAM, docker appears to be consuming ~50mb of that. This is running 17 containers of nginx, postgres, nodejs, haproxy etc. I'm ok with this level of overhead for the benefits of containerization - several years ago I was running a bunch of PHP sites on Apache, one was compromised and this took down the rest as well. In addition to the isolation it also simplifies my deployment story significantly. If K3s has a similar level of overhead then I should probably move to this, something for me to look into, however my understanding was that components like etcd require a fairly significant amount of resource even for tiny one node "clusters".
