Overview :-

In the fast-evolving landscape of DevOps and Kubernetes, managing deployments efficiently is key. This Medium article provides a step-by-step guide on setting up ArgoCD, a popular GitOps tool, within a Minikube environment. From installation to deployment, we’ll explore the seamless process of orchestrating application releases using ArgoCD.

To install Argocd on Minikube and deploy a application on argocd:-

• First, start the Minikube using a driver to create a minikube cluster. I am using the docker driver to start the minikube.

• Command to start the minikube using a driver;

minikube start --driver=docker

Create a Namespace for argocd and apply ArgoCD manifest installation file from ArgoCD github repository.

• Namespace: command to create a name space

kubectl create ns argocd

Apply the file: comand to apply the installation file

kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/v2.5.8/manifests/install.yaml

• Check the objects installed in Argocd Namespace using the below command -

kubectl get all -n argocd

• Argocd had a user interface. It has a dashboard which shows the current applications and their health. To access the web GUI of ArgoCD, we need to do a port forwarding. For that we will use the argocd-server service

• Run below command to port the argocd –server service

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

• Now, Go to the browser and open localhost: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.

• To login to the argocd interface, we need to enter the credentials. The default username is admin and initial password will get from argocd through minikube terminal -

• Command to get the initial password -

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

• Once u get the password, copy it and paste in the argocd GUI then click on sign in.

• After logging in the argocd interface will looks like below -

Deploying a test application in Argocd :-

• To Deploy a test application in argocd, we have to connect with our Github to get the source code. so, I will connect with my Github.

• Click on the settings icon in the argocd interface and then click on the Repositories as shown in the below picture -

• Now, For the connection method, choose HTTPS, for Project choose default, and enter your github repo as repository URL. Finally, hit on connect.

• connect to the Repository as shown in below figure

• After connecting with the Github repo, u can able to see the added repository on your settings icon.

• Now, click on the three dots which is present just before the successful message. The pop up menu will have a create applicationoption. As shown in the below image

• Choose create application option from the the popup menu.

• Enter test as the application name, choose default for Project Name, and choose Automatic for Sync Policy.

• once you have entered the details, click on create. Then the details of the app is shown in applications icon.

• The application is shown in below figure

• Click on the app to get a detailed view of the application.

Conclusion :-

• Finally, we have setup the Argocd on minikube and Deployed an application and Also we have seen the work flow the argocd in the above document.
