HTTPS

Follow this quick start guide and install certmanager via helm and tiller:

$ kubectl create serviceaccount tiller --namespace=kube-system
$ kubectl create clusterrolebinding tiller-admin --serviceaccount=kube-system:tiller --clusterrole=cluster-admin
$ helm init --service-account=tiller
$ helm repo update
$ helm install stable/nginx-ingress
$ kubectl apply -f https://raw.githubusercontent.com/jetstack/cert-manager/release-0.6/deploy/manifests/00-crds.yaml
$ helm install --name cert-manager --namespace cert-manager stable/cert-manager

Create letsencrypt issuers. Change the email address in these files before running this command.

# in folder deployment/digital-ocean/https/
$ kubectl apply -f issuer.yaml

Create an ingress service in namespace human-connection. Change the domain name according to your needs:

# in folder deployment/digital-ocean/https/
$ kubectl apply -f ingress.yaml

Check the ingress server is working correctly:

$ curl -kivL -H 'Host: <DOMAIN_NAME>' 'https://<IP_ADDRESS>'

If the response looks good, configure your domain registrar for the new IP address and the domain.

Now let's get a valid HTTPS certificate. According to the tutorial above, check your tls certificate for staging:

$ kubectl describe --namespace=human-connection certificate tls
$ kubectl describe --namespace=human-connection secret tls

If everything looks good, update the issuer of your ingress. Change the annotation certmanager.k8s.io/issuer from letsencrypt-staging to letsencrypt-prod in your ingress configuration in ingress.yaml.

# in folder deployment/digital-ocean/https/
$ kubectl apply -f ingress.yaml

Delete the former secret to force a refresh:

$ kubectl  --namespace=human-connection delete secret tls

Now, HTTPS should be configured on your domain. Congrats.
