Hi,

I am student and so new in Rancher, I installed Rancher on a single node using Docker. I have DNS record ([rancher.mydomian.com](http://rancher.mydomian.com)) and used these commands for install Rancher(v2.5.5) :

```auto
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](http://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?

Best regards,
