I am student and so new in Rancher, I installed Rancher on a single node using Docker. I have DNS record (rancher.mydomian.com) and used these commands for install Rancher(v2.5.5) :
docker run -d --restart=unless-stopped \ -p 80:80 -p 443:443 \ --privileged \ rancher/rancher:latest \ --acme-domain <YOUR.DNS.NAME>
Certificate will expire soon and I could not find way the renew it.
Letsencrypt certificate chain of trust looks like :
DST Root CA x3 → R3 → rancher.mydomian.com
I could not find the exact path for the certificate in my server (centos8) and rke command is not working(probably I did not install it).
How can I trigger a certificate refresh?
