# Securing Argo

[Argo](https://argoproj.github.io/projects/argo) is an open-source container-native workflow engine for orchestrating parallel jobs on Kubernetes. This guide covers how to add authentication and authorization to Argo using Pomerium.

## Install Argo

To install Argo in Kubernetes you can either follow the instructions [here](https://github.com/argoproj/argo/blob/master/docs/getting-started.md), or use [Helm](https://github.com/argoproj/argo-helm/tree/master/charts/argo). This guide will use the Helm chart.

Run the following commands:

```bash
helm repo add argo https://argoproj.github.io/argo-helm
helm repo update
helm install \
    --namespace kube-system \
    --set minio.install=true \
    --set installCRD=false \
    argo argo/argo
kubectly apply \
    --namespace kube-system \
    --file https://raw.githubusercontent.com/argoproj/argo/master/manifests/base/crds/workflow-crd.yaml
```

You should now have a working Argo installation using [Minio](https://min.io/) to store artifacts. Both Argo and Minio provide web-based GUIs. Confirm that Minio is working by running:

```bash
kubectl --namespace kube-system port-forward svc/argo-minio 9000:9000
```

You should now be able to reach the Minio UI by accessing <http://localhost:9000/minio>. If you're curious the Access Key and Secret Key are generated by the Helm chart and stored in a Kubernetes secret:

```bash
kubectl --namespace=kube-system get secret argo-minio -o yaml
```

For now though, let's terminate the Minio `kubectl port-forward` and create one for the Argo UI:

```bash
kubectl --namespace kube-system port-forward svc/argo-server 2746:2746
```

Visiting <http://localhost:2746> should take you to the Argo Workflows dashboard.

## Install NGINX Ingress Controller

We will use [NGINX](https://kubernetes.github.io/ingress-nginx/deploy/#using-helm) as our ingress controller. To install it with Helm run the following commands:

```bash
helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm repo update
helm install --namespace kube-system ingress-nginx ingress-nginx/ingress-nginx
```

## Install Pomerium

Like with Argo we will install Pomerium using the [Helm chart](https://github.com/pomerium/pomerium-helm). First create a `values.yaml` file (replacing the `email.is` and IDP `provider`/`clientID`/`clientSecret` with your own):

```yaml
config:
  routes:
    - from: https://argo.localhost.pomerium.io
      to: http://argo-server.kube-system.svc.cluster.local:2746
      policy:
        - allow:
            or:
              - email:
                  is: bdd@pomerium.io

authenticate:
  idp:
    provider: google
    clientID: REPLACE_ME
    clientSecret: REPLACE_ME

ingress:
  annotations:
    nginx.ingress.kubernetes.io/backend-protocol: https
```

Run the following commands (replacing the IDP `provider`/`clientID`/`clientSecret` with your own):

```bash
helm repo add pomerium https://helm.pomerium.io
helm repo update
helm install \
    --set config.sharedSecret="$(head -c32 /dev/urandom | base64)" \
    --set config.cookieSecret="$(head -c32 /dev/urandom | base64)" \
    --values values.yaml \
    pomerium pomerium/pomerium
```

You should now be able to reach argo by using `kubectl port-forward` with the NGINX ingress controller (binding :443 may require using sudo with kubectl):

```bash
kubectl --namespace kube-system port-forward svc/ingress-nginx-controller 443:443
```

And visit: <https://argo.localhost.pomerium.io/>.
