Troubleshooting

Dashboard won't connect

1. Check kubectl proxy is running:

curl http://localhost:8001/api/v1/namespaces/default/pods

Pods not appearing

1. Check if pods are running:

kubectl get pods -l app=rolling-demo
kubectl get pods -l app=canary-demo
kubectl get pods -l app=bluegreen-demo

2. Check namespace:

• Dashboard is configured for the default namespace
• Ensure deployments are in the default namespace

CORS Errors (when using HTTPS API URL)

This is common with direct API access. Solutions:

1. Use kubectl proxy instead:

kubectl proxy --port=8001

2. Or visit the API URL in your browser first and accept the certificate
