I put all resources related to the Dashboard into the namespace where the Dashboard lives. Now let us create a ClusterIssuer, cluster-issuer.yaml. Important: this secret needs to be in the same namespace as cert-manager is in, otherwise it will be unable to read the secret. I need to create a secret with my Cloudflare API Token, cf-secret.yaml: apiVersion: v1 I use Cloudflare, and therefore it makes sense for me to use a DNS01 Challenge Provider instead of HTTP01 moreover, cert-manager supports CLoudflare out of the box. Issuers, and ClusterIssuers, are Kubernetes resources that represent certificate authorities (CAs) that can generate signed certificates by honoring certificate signing requests. The next step would be to setup an Issuer or a ClusterIssuer. VERSION_KUBE_DASHBOARD=$(curl -w '%/cert-manager.yaml If the Kubernetes Dashboard has not yet been installed, you will obviously need to install it.įor microk8s, this is as easy as running microk8s enable rbac dashboardįor k3s, this will be a bit more difficult: GITHUB_URL= To /etc/rancher/k3/config.yaml and restart k3s (e.g., systemctl restart k3s). To disable Traefik, you will need to add disable: I have tested the configuration provided in this post on k3s (Rancher) and microk8s clusters.Ī note to k3s users: k3s ships with Traefik ingress controller in this post, I am using nginx ingress controller.
The only prerequisite is to have a running Kubernetes cluster.

Sometimes it is convenient to expose the Kubernetes Dashboard to manage the cluster instead of using the console and kubectl.
