Possible to run k3s on one node (server and agent together)?

[dannyyy]

Is it possible to run the k3s server and agent on the same node like minikube or microk8s?

If yes, how is the setup / configuration process different? What is to consider?

[udanpe]

This is default behavior. But if you want run pod on the master with kubeadm its not a problem too. Just run
kubectl taint nodes --all node-role.kubernetes.io/master-

Would k3s + k3d meet your needs?

When you install K3s with the curl script like below, the node will be both a server and agent.

curl -sfL https://get.k3s.io | sh -

So, by default the server and agent are deployed together on the same node.

The current way of dealing with it is using labels, not taints - what @udanpe suggested does at least no longer work.

I commented this here rancher/k3os#624 (comment) with an alternatives using labels - if anybody runs into this issue like i have 👍 Thanks for all the hints here!

On K3s by default, all servers are also agents.
