Streamlining Your Kubernetes Deployments with Argo CD CLI and UI

Argo CD is a powerful and flexible GitOps tool for Kubernetes deployments that automates the deployment and management of applications. It follows the GitOps principles, which means that it uses Git repositories as the single source of truth for the desired state of the applications and the cluster. Argo CD continuously monitors the Git repository for any changes, and compares the current state of the cluster with the desired state defined in the repository.

Now let's walk through step by step how Argo CD can be install in local Ubuntu machine . This can be also applied in any VM or Image belongs to AWS,Azure or GCP .

1. Open a terminal window on your Ubuntu machine.
2. Download the latest version of the Argo CD CLI by running the following command:

$ curl -sSL -o argocd-linux-amd64 https://github.com/argoproj/argo-cd/releases/latest/download/argocd-linux-amd64
        

1. Make the downloaded binary executable by running the following command:

$ chmod +x argocd-linux-amd64
        

1. Move the binary to a directory in your system’s PATH by running the following command:

$ sudo mv argocd-linux-amd64 /usr/local/bin/argocd
        

1. Verify that the installation was successful by running the following command:

$ argocd version
        

6. To view the pods in the argocd namespace, run the following command:

$ kubectl get pods -n argocd
        

7. To view the services in the argocd namespace, run the following command:

$ kubectl get services -n argocd
        

8. To view the deployments in the argocd namespace, run the following command:

$ kubectl get deployments -n argocd
        

9. Log in to the Argo CD server by running the following command:

$ argocd login <ARGOCD_SERVER> --username admin --password <ARGOCD_PASSWORD>         

10. You can extract the Argo CD admin password by running the following command:

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

11. For Minikube only changed the type as NodePort instead of Cluster IP to browse externally

12. Then execute the below steps to get the local host with port binding to launch the Argo CD UI

13. Copy the above local host URL and it will appear as external browser

14. Post login using Admin privileges and navigate to Application icon you will fill up all of the below CLI arguments and Argo CD application sets will be launched .

15. To create an application via Argo CD CLI . There is a reference of GitHub Repo which you folks can walk through

https://github.com/argoproj/argocd-example-apps.git        

16. Now create the application use the below command

argocd app create guestbook --repo https://github.com/argoproj/argocd-example-apps.git --path guestbook --dest-namespace default --server https://kubernetes.default.svc        

17. Now navigate to same UI and it will display Application set successful launch .
