Hello,
we have a cluster with 3 nodes on the same vlan.
We try to remove one node of this cluster to add a new node from another vlan on an other datacenter.
We have open these flows between the 2 vlan's :
Step to do this :
- Update custom certificate with new SAN for the future new node : vracli certificate ingress --sha256 7431e5f4c3xxxxxxxx --set vrodit_my_certificate.pem
- Update deployment :/opt/scripts/deploy.sh
- remove node 3 of the cluster :vracli cluster leave
- Add new node in the cluster : vracli cluster join primary_node_hostname_or_IP
- Update deployment :/opt/scripts/deploy.sh
Below our error :
