Single Node - Letsencrypt - Auto Renew


just started Rancher with this command for a single node installation:
docker run -d --restart=unless-stopped
-p 80:80 -p 443:443
–acme-domain <YOUR.DNS.NAME>

The letsencrypt cert is now valid for 3 months.

Is there a way to renew the cert automatically oder do i have to stop the process and start again?
Thanks for advice.

With both single node and HA Rancher, cert-manager takes care of renewing the cert 30 days before it expires.

Important note: Single node Rancher is not designed/recommended for Production use.

Do i have to install cert-manager and deploy a config or is it enough to install cert-manager?
