How to Deploy Application on Minikube using ArgoCD UI

In this article we are going to cover How to Install ArgoCD on Minikube and How to Deploy Application on Minikube using ArgoCD UI.

Prerequisite:

• Install minikube
• Install kubectl

Step #1:Install Argocd on Minikube

Start the minikube Kubernetes cluster on Ubuntu 22.04 LTS

minikube start --vm-driver docker

Just like other Kubernetes tools, ArgoCD requires a namespace with its name. Therefore, we will create a namespace for argocd.

kubectl create namespace argocd

ArgoCD can be installed using its manifests. First, you’ll need to download these manifests and apply them to your Minikube cluster.

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

Once the installation completes successfully, you can use the watch command to check the status of your Kubernetes pods:

watch kubectl get pods -n argocd

Step #2:Access ArgoCD UI on Browser

By default, the ArgoCD server is not exposed outside the cluster. You can expose it using port-forwarding to access the ArgoCD UI.

kubectl port-forward svc/argocd-server -n argocd --address 0.0.0.0 8080:443

The ArgoCD UI will be available at http://localhost/IP:8080. Access it through your web browser.

Now we can go to a browser and open instance_ip:8080

You will see a privacy warning. Just ignore the warning, click on Advanced and then hit on Proceed to localhost (unsafe) to continue to the GUI interface. (Your browser setting may present a different option to continue).

Get the initial password for the admin user to log in

kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d

Step #3:Deploy Application on Minikube using ArgoCD UI

Here we are going to deploy GuestBook Application from ArgoCD official example apps repository.

After logging in, click the + New App button as shown below:

Give your app the name helm-guestbook, use the project default, and leave the sync policy as Manual:

Connect the ArgoCD Example apps repo to Argo CD by setting repository url to the github repo url, leave revision as HEAD, and set the path to helm-guestbook:

For Destination, set cluster URL to https://kubernetes.default.svc (or in-cluster for cluster name) and namespace to default:

Click on SYNC

To check help-guestbook pods status using kubectl

kubectl get pods

To check help-guestbook deployment status using kubectl

kubectl get deploy

To check help-guestbook service status using kubectl

kubectl get svc

After App Heath is Healthy. To access helm-guestbook deployment on browser forward svc/helm-guestbook to port 9090 using kubectl

kubectl port-forward --address 0.0.0.0 svc/helm-guestbook 9090:80

After that Instance_ip:9090 hit on browser you will get the output
