ETCD HA - RKE config file

[qdupuy]

Hello,

Is it necessary to put the etcd configuration in the config.yaml file on each rke2 master node?

[brandond]

Yes, all nodes need to be configured.

[brandond]

All the nodes that you want to have register with the cluster, yes? How else would they find it?

[qdupuy]

I currently have 3 master nodes.

The first one does not have the "server" variable, should I put it in? For the other two servers this will be the case

[brandond]

No, the first server node starts the cluster. All other nodes must join the cluster via connecting to an existing server.

Thank you, I have just created a LB.

Small question, on the canal pods I have this error:

k -n kube-system logs -f rke2-canal-wm4xd kube-flannel
I1021 09:44:56.166674       1 main.go:212] Could not find valid interface matching netk8s03@eno2: error looking up interface netk8s03@eno2: route ip+net: no such network interface
E1021 09:44:56.166906       1 main.go:236] Failed to find interface to use that matches the interfaces and/or regexes provided

My network configuration was done via netplan on ubuntu.

The iface variable of flannel does not take into account the @ ?

Apparently not? Have you tried allowing it to find the correct interface automatically, instead of specifying it?
