ArgoCD pipeline integration with GitHub

Docker and Kubernetes are both popular technologies in the world of containerization and container orchestration. Integrating GitHub with ArgoCD allows you to automate the deployment of your Kubernetes applications by using Git repositories as the source of truth for your application manifests. - Docker and Kubernetes Training

Here's a step-by-step guide on how to integrate GitHub with ArgoCD:

Prerequisites:

1. ArgoCD Installed: Ensure that ArgoCD is installed and running in your Kubernetes cluster.

2. GitHub Repository: Have a GitHub repository that contains your Kubernetes manifests and configuration files. - Kubernetes Online Training

Integration Steps:

1. Create a GitHub Repository: If you don't already have a GitHub repository, create one and push your Kubernetes manifests (e.g., YAML files) to this repository.

2. Access ArgoCD Web UI: Open the ArgoCD web UI by accessing the ArgoCD server's URL. You might need to port-forward or expose the ArgoCD service to access the UI.

3. Add a New Application in ArgoCD:

 Click on the '+ New App' button in the ArgoCD UI.

 Provide a name for your application. - Docker Online Training

 In the 'Project' field, select the appropriate project or create a new one.

 In the 'Source' section, select 'Git' as the repository type.

 Enter your GitHub repository URL in the 'Repository URL' field.

 Enter the path to your Kubernetes manifests within the repository (e.g., `/path/to/manifests`).

 Configure other settings as needed (e.g., sync policy, auto-sync).

4. Sync the Application: After adding the application, click on the application name in the ArgoCD UI.

Click on 'Sync' to manually sync the application. Alternatively, you can enable auto-sync during the application creation. - Kubernetes Training Hyderabad

5. GitHub Webhook Configuration: In your GitHub repository, go to Settings > Webhooks.

Click on 'Add webhook'.

Set the Payload URL to your ArgoCD server's webhook endpoint    

Set the Content type to 'application/json'.

Choose individual events or set it to send 'Just the push event'.

Save the webhook.

6. Verify the Integration: Make changes to your Kubernetes manifests in the GitHub repository. Commit and push the changes. Check the ArgoCD UI to see if the application syncs automatically or manually initiate a sync.
