Troubleshooting

Plugin Not Appearing

Check plugin directory:

# macOS
ls -la ~/Library/Application\ Support/Headlamp/plugins/headlamp-sealed-secrets/

# Linux
ls -la ~/.config/Headlamp/plugins/headlamp-sealed-secrets/

# Should show: main.js and package.json

Verify Headlamp version:

headlamp --version  # Should be >= v0.13.0

Check browser console:

1. Open Headlamp
2. View → Toggle Developer Tools
3. Look for errors in Console tab

Controller Not Found

Verify controller is running:

kubectl get pods -n kube-system -l name=sealed-secrets-controller
# Should show: Running pod

Check controller service:

kubectl get svc -n kube-system sealed-secrets-controller
# Should exist with ClusterIP

Reinstall if needed:

kubectl apply -f https://github.com/bitnami-labs/sealed-secrets/releases/download/v0.24.0/controller.yaml

Permission Errors

Check RBAC permissions:

# Can you list SealedSecrets?
kubectl get sealedsecrets --all-namespaces

kubectl get svc -n kube-system sealed-secrets-controller

Verify CRD exists:

kubectl get crd sealedsecrets.bitnami.com
