# ArgoCD Demo

## Install Kubernetes locally

Install [Docker Desktop](https://www.docker.com/products/docker-desktop) first and enable Kubernetes in the preferences. This will give you a local Kubernetes cluster to work with.

## Install ArgoCD on your Kubernetes cluster

First, clone this Git repository.

Create a namespace for ArgoCD to live in.

```

kubectl create namespace argocd

```

And install ArgoCD into the namespace.

```

kubectl -n argocd apply -f ./argocd/install.yaml

```

Instead of using the install yaml from this repository, you can also deploy the latest one from ArgoCD.

```

kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

```

## Port forward the dashboard

Because this is a demo I'm not gonna bother with a proper load balancer or ingress controller - I'm just going to temporarily port forward the dashboard.

```

kubectl port-forward svc/argocd-server -n argocd 8080:443

```

You can now access the dashboard via [localhost](http://localhost:8080/) (ignore any SSL warnings).

The default username is `admin` and the password is the name of the ArgoCD API pod, for example: `argocd-server-6744f57d55-26ctk`. 

You can look up the pod name using:

```

kubectl get pods -n argocd

```

## Deploy Nginx

Now we can deploy the example deployment I created, it will deploy Nginx.

```

kubectl apply -f ./argocd/nginx.yaml

```

Any changes that you push to the Git repository will be automatically deployed because ArgoCD constantly watches for changes. ArgoCD will also self-heal all parts of the deployment if it detects anything is out of sync.
