Hetzner Setup

Setup cloud instance and firewall with the following ports 22, 80 and 443.

After that connect to the instance over ssh and in update + upgrade everything:
apt update -y && apt upgrade -y

To install k3s run the following command:
curl -sfL https://get.k3s.io | sh -

To get the kube config execute the following command:
scp root@remoteHost:/etc/rancher/k3s/k3s.yaml ~/.kube/k3s-config

Accessing The Cluster

To get acces to the cluster make a safety copy of your current ~/.kube/config and rename the copied config from your setup. After that you have to forward the kubernetes API-Port from your server to your local machine:
ssh -L 6443:remoteHost:6443 root@remoteHost
Now you should be able to run kubectl commands on your cluster.

cert-manager Setup

Since cert-manager is part of our helm chart we have to make sure the crd is installed beforehand so we have access to all resources. We do that with the following command:
kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.1.1/cert-manager.crds.yaml

Starting the chart

If we want to run the chart in its own namespace we can do so by creating one and switching to it. Here we create the namespace prod:
kubectl create namespace prod && kubectl config set-context --current --namespace=prod
We should also make sure that our DNS is pointing to the correct IP so cert-manager can fetch the certificate without a problem. Now we can just run our chart and we should be good to go :)
