rook: minikube 0.28+ VM dies after installing wordpress/mysql

Is this a bug report or feature request?

Bug Report

Deviation from expected behavior: After installing mysql/wordpress, the wordpress site should be functional and accessible. Instead, the entire minikube VM dies and things like minikube ssh and minikube ip just hang. kubectl commands hang as well.

Expected behavior: Minikube to be functional after wordpress/mysql are installed.

How to reproduce it (minimal and precise):

cd ${GOPATH}/src/github.com/rook/rook/cluster/examples/kubernetes/ceph
kubectl create -f operator.yaml
kubectl create -f cluster.yaml
kubectl create -f storageclass.yaml
cd ${GOPATH}/src/github.com/rook/rook/cluster/examples/kubernetes
kubectl create -f mysql.yaml
kubectl create -f wordpress.yaml

Shortly after this point, minikube and kubectl commands hang, making this very hard to troubleshoot.

Workaround

This behavior can be worked around by reverting minikube to v0.27.0 and Kubernetes 1.10.

Same problem here. I cannot reproduce it reliably. I used minikube ssh and toolbox, installed htop there and the VM uses roughly 1.5GB RAM. 800Mb of it are my own kubernetes apps. Using minikube dashboard I can see that the whole rook-ceph namespace uses about 850Mb RAM. So I’m not sure about where the crash originates from, but it’s not from a lack of resources.
