I have reactjs app running on my pod and I have mounted source code from the host machine to the pod. It works fine but when I change my code in the host machine, pod source code also changes but when I run the site it has not affected the application. here is my manifest, what I'm doing wrong?

what Rico has mentioned is correct, you need to patch or rebuild with every changes, but you can avoid that by running minikube without vm-driver here is the command to run minikube without vm-driver only works in Linux, by doing this you can mount host path to pod. hope this will help
sudo minikube start --bootstrapper=localkube --vm-driver=none --apiserver-ips 127.0.0.1 --apiserver-name localhost -v=1Basically, you need to reload your application everytime you change your code and your pods don't reload or restart when you change the code under the /code directory. You will have to re-create your pod since you are using a deployment you can either:
kubectl delete <pod-where-your-app-is-running>or
export PATCH='{"spec":{"template":{"metadata":{"annotations":{"timestamp":"'$(date)'"}}}}}'
kubectl patch deployment webapp -p "$PATCH"Your pods should restart after that.
