Deploying Go Application in Kubernetes using Argo CD

This repository demonstrates an example of deploying a Go application in Kubernetes using Argo CD, a declarative continuous delivery tool. Argo CD automates the synchronization of your Kubernetes cluster with the desired state defined in a Git repository, ensuring a reliable and automated deployment process.

Prerequisites

Before deploying the Go application, ensure you have the following prerequisites:

• Kubernetes cluster up and running
• Argo CD installed in your Kubernetes cluster

Getting Started

To get started with deploying the Go application using Argo CD, follow these steps:

1- Clone this repository:

git clone https://github.com/mahmoudmohamed22/GitOps.git

2- Modify the Kubernetes manifests:

Navigate to the Deployment-App directory. Update the deployment.yaml, service.yaml files with your specific application configurations.

3- Configure Argo CD:

Ensure Argo CD is configured and accessible in your Kubernetes cluster. Update the application.yaml file with the correct application and repository details.

4- Push changes to your repository:

Commit and push the modified Kubernetes manifests and the updated application.yaml file to your repository.

5- Access the Argo CD UI:

• Open the Argo CD UI in your web browser.
• Log in using the appropriate credentials.
• Create an application in Argo CD, specifying the repository and target cluster details.
• Argo CD will automatically detect the changes and begin deploying the Go application to the Kubernetes cluster.

install ArgoCD in local Kubernetes

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

get argocd pods

get SVC in k8s

to access argocd from ui , need edit service to forward

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

to get password from secrets and then decode with base64 to solve hashing password to right password

kubectl get secret  argocd-initial-admin-secret -n argocd -o yaml

To run Argocd Config "application.yaml" to run app and sync app from git

kubectl apply -f application.yaml
