Greetings friends. I am trying to install RKE2 on 3 centos8 servers. When i configure the first node with the config.yaml in /etc/rancher/config.yaml it causes the node to crash and not start clean. Ive tried to get the system to recognize the other server nodes but simply cant get it to work. I can get it to work with a single node. Any help would be greatly appreciated.

hey @bored-rain-98291 are you trying to get a 3-node HA master setup?
and it’s CentOS 8 Stream I assume 🙂

when it’s crashing is it the rke2-server service?

and would you be able to put your 
config.yaml
here? I have a working 3-master RKE2 deployment on CentOS 8 Stream
so may be able to help you

sure one moment
standby
I assume the first node gets this config.yaml as well? not just 2 & 3?

so 2&3 will need an extra attribute called 
server
that essentially tells RKE2-server that they are replicated masters
Master A
          cloud-provider-name: aws
          cluster-cidr: 10.0.0.0/12
          service-cidr: 10.96.0.0/12
          node-taint:
            - "CriticalAddonsOnly=true:NoExecute"

ah i see. Sorry im in an air-gapped environment so i have to take special steps to copy configs out.
So that config is what you have on every server node?

Master B / C
          server: https://<LOAD BALANCER DNS>:9345
          cloud-provider-name: aws
          cluster-cidr: 10.0.0.0/12
          service-cidr: 10.96.0.0/12
          node-taint:
            - "CriticalAddonsOnly=true:NoExecute"
np there isn’t much to the configs

mine is self-installed
no cloud yet

but honestly it’s the 
server
that’s the main difference

ok cool - thanks! i will try that

bare-metal?
I have not tried RKE2 on bare metal yet, so you most likely will need a LoadBalancer service like MetalLB

Its in vmware i believe
setup by another team 😉
i was hoping it would be aws but not yet apparantly
yes i figured we would need something for the lb
The last time i setup rancher was years ago and you deployed it to a vanilla kubernetes cluster.

yup! there’s also some tie-in with k3s in the RKE2 project as well but I’m not 100% sure what that relationship to k3s is yet
**I believe
could be wrong but I think the automated installation may come from k3s
