I'm currently using custom certificates for RKE/Rancher, how do I renew custom certificates?

337 Views Asked by At

Does renewing RKE custom certificates signed by private CA follows the same process as renewing certificates generated by RKE (e.g. rke cert-rotate)?

I think so, because they write about keeping the same CA in documentation when rotating the cert, here is the procedure:

  1. In the upper left corner, click ☰ > Cluster Management.
  2. On the Clusters page, go to the cluster you want to rotate certificates for and click ⋮ > Rotate Certificates.
  3. Select which certificates that you want to rotate: Rotate all Service certificates (keep the same CA) or Rotate an individual service and choose one of the services
  4. Click Save.

If you want to rotate RKE certs, the cluster should be "local".
