ArgoCD Demo
Install Kubernetes locally
Install 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 (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.
