I will briefly describe how it works. The main work is performed by a server agent (https://github.com/r2dtools/agent), which is installed on the server. After installing the agent, you can register it in your account.

I am using cert-manager 0.5.2 to manage Let's Encrypt certificates on our Kubernetes cluster.

helm repo add rancher-latest https://releases.rancher.com/server-charts/latest helm repo add jetstack https://charts.jetstack.io kubectl apply -f https://github.com/jetstack/cert-manager/releases/download/v1.6.1/cert-manager.crds.yaml helm upgrade -i cert-manager jetstack/cert-manager --namespace cert-manager --create-namespace helm upgrade -i rancher rancher-latest/rancher --version 2.5.4 --create-namespace --namespace cattle-system --set hostname=rancher.zbs.local --set bootstrapPassword=bootStrapAllTheThings --set replicas=1
