# RKE2 Cluster Configuration HOWTO
|
|
|
|
The package warewulf4-overlay-rke2 provides a configuration template
|
|
to share a connection token - a shared secret - and the hostname of
|
|
the first server endpoint across an RKE2 cluster.
|
|
To use it,
|
|
|
|
- create a profile `rke2-config-key`:
|
|
|
|
```
|
|
wwctl profile add rke2-config-key
|
|
token="$(printf 'K'; \
|
|
for n in {1..20}; do printf %x $RANDOM; done; \
|
|
printf "::server:"; \
|
|
for n in {1..20}; do printf %x $RANDOM; done)"
|
|
wwctl profile set --tagadd="connectiontoken=${token}" \
|
|
-O rke2-config rke2-config-key
|
|
```
|
|
- create a profile `rke2-config-first-server`:
|
|
|
|
```
|
|
server=<hostname_of_first_rke2_server>
|
|
wwctl profile add rke2-config-first-server
|
|
wwctl profile set --tagadd="server=${server}" -O rke2-config rke2-config-first-server
|
|
|
|
```
|
|
- add the `rke2-config-key` profile to the server node:
|
|
|
|
```
|
|
wwctl node set -P default,rke2-config-key $server
|
|
|
|
```
|
|
- finally, add both profiles to the agent nodes:
|
|
|
|
```
|
|
agents="<agent_list>"
|
|
wwctl node set -P default,rke2-config-key,rke2-config-first-server $agents
|
|
```
|
|
|
|
In case the RKE2 server node is not deployed by Warewulf, you will
|
|
have to grab the connection token (see variable `token` above) from
|
|
the file `/var/lib/rancher/rke2/server/node-token` on the running
|
|
server.
