Note port-forwarding still has to happen for this to work.

echo "https://${CODESPACE_NAME}-8080.app.github.dev/dev/blue"

Create the red app on Development environment

kubectl create -f dev/red

Check the status of the pods and see the red and blue pods running:

kubectl get pods -n dev

Afterwards, you can visit the app via curl:

curl http://${INGRESS_IP}/dev/red

Or, reach via below URLs:
