# Setup Ingress and HTTPS

Follow [this quick start guide](https://docs.cert-manager.io/en/latest/tutorials/acme/quick-start/index.html) and install certmanager via helm and tiller:

```text
$ 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.

```bash
# 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:

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

Check the ingress server is working correctly:

```bash
$ 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:

```bash
$ 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`.

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

Delete the former secret to force a refresh:

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

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