Install Rancher with Let's Encrypt on Kubernetes

Centralized Multi-Cluster Kubernetes Management

SUSE Rancher provides a unified control plane for importing, provisioning, and governing multi-cluster Kubernetes fleets across cloud and on-premises environments.

Step-by-Step Deployment

1. Install cert-manager for Automated TLS

helm repo add jetstack https://charts.jetstack.io
helm repo update

helm install cert-manager jetstack/cert-manager \
  --namespace cert-manager \
  --create-namespace \
  --set crds.enabled=true

2. Install Rancher with Let’s Encrypt Ingress TLS

helm repo add rancher-latest https://releases.rancher.com/server-charts/latest
helm repo update

kubectl create namespace cattle-system

helm install rancher rancher-latest/rancher \
  --namespace cattle-system \
  --set hostname=rancher.mkbn.in \
  --set bootstrapPassword=admin \
  --set ingress.tls.source=letsEncrypt \
  --set letsEncrypt.email=admin@mkbn.in \
  --set letsEncrypt.ingress.class=nginx

Monitor the rollout using kubectl -n cattle-system rollout status deploy/rancher until all replicas are healthy and the Let’s Encrypt Certificate resource reaches Ready=True.
