+# First we setup the ingress controller with helm

+helm repo update
+# Now we can install this to our cluster
+helm install --kubeconfig config.yaml traefik traefik/traefik
+```
+
+# Prove the service is present with
+
+```sh
+kubectl --kubeconfig config.yaml get svc
+```
+
+# Create the pods
+
+```sh
+kubectl --kubeconfig config.yaml -f k8s/nginx-dep.yaml

+
+# Expose on port 80
+
+```sh
+kubectl --kubeconfig config.yaml -f k8s/nginx-service.yaml

+# Create ingress on k8s
+
+```sh
+kubectl --kubeconfig config.yaml -f k8s/traefik-ingress.yaml
+```
+
+# Take the external IP from the ingress 
+
+Put that into terraform's A record for the domain since this is a load balancer
+in Vultr ( actual resource apparantly )
+
+# Configure cert-manager for traefik ingress
+
+Using the latest version from here:
+https://github.com/cert-manager/cert-manager/releases/download/v1.14.2/cert-manager.crds.yaml
+
+```sh
+kubectl --kubeconfig config.yaml \
+	apply --validate=false \
+	-f https://github.com/cert-manager/cert-manager/releases/download/v1.14.2/cert-manager.yaml
+```
+
+# Create the cert issuer and certificate
+
+
+```sh
+kubectl --kubeconfig config.yaml apply -f k8s/letsencrypt-issuer.yaml
+kubectl --kubeconfig config.yaml apply -f k8s/letsencrypt-issuer.yaml
+```
+
+Because we just have 1 cert for now we are looking for it's status to be `READY`
