Answer 1

Changing type: Directory to type: DirectoryOrCreate works for me.

Answer 2

If by any chance you are using minikube, then don't forget that minikube itself is a container. So hostPath points to a path in that container, not to a path on your host machine. You have to mount your PC path into the minikube container and then into the POD.

Example: minikube start --mount --mount-string="/host/path:/minikubeContainer/path"

Answer 3

You are creating the docker container directly on the master node. As a result of this you could be able to run docker container with the newly created directory. But when you launch the kubernetes yaml file, it intends to run on a worker node. Since you create the directory on the master node, kubelet cannot find directory on worker node and failing. That's why "DirectoryorCreate" value on type flag is a kind of solution for this.

Answer 4

Removing type: Directory from the mongodb.yml works as expected
