What is Argo CD Argo CD UI not loading

Understanding Argo CD

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. It automates the deployment of the desired application states in the specified target environments. Argo CD continuously monitors running applications and compares the current, live state against the desired target state (as specified in the Git repository). If there is a drift, it can automatically or manually synchronize the application to the desired state.

Steps to Fix the Issue

1. Check Argo CD Server Logs

Start by checking the logs of the Argo CD server to identify any errors or warnings. You can do this by executing the following command:

kubectl logs -n argocd deploy/argocd-server

Look for any error messages that might indicate what is causing the UI to not load.

2. Verify Service Configuration

Ensure that the Argo CD server service is correctly configured. Check the service details using:

kubectl get svc -n argocd

Ensure that the service type and ports are correctly set up. For more information on service configuration, refer to the Argo CD Ingress Documentation.

3. Check Network Policies

If network policies are in place, ensure they allow traffic to the Argo CD server. You can list network policies with:

kubectl get networkpolicy -n argocd

Review the policies to ensure they are not blocking access to the Argo CD server.

4. Inspect Kubernetes Resources

Check the status of the Argo CD pods to ensure they are running correctly:

kubectl get pods -n argocd

If any pods are not running, describe them to get more details:

kubectl describe pod -n argocd
