none: oracle-db deployment causes: etcdserver: request timed out

[tstromberg]

From Arlan on #minikube Slack:

• AzureVM
• Standard_D16s_v3
• UbuntuServer 18.04-LTS

$ sudo minikube start --vm-driver none
devstackuser@arlan-testerTFVM:~$ sudo minikube start --driver none
�  minikube v1.8.2 on Ubuntu 18.04
✨  Using the none driver based on user configuration
�  Running on localhost (CPUs=16, Memory=64401MB, Disk=29598MB) ...
ℹ️   OS release is Ubuntu 18.04.4 LTS
�  Preparing Kubernetes v1.17.3 on Docker 19.03.6 ...
    ▪ kubelet.resolv-conf=/run/systemd/resolve/resolv.conf
�  Launching Kubernetes ...
�  Enabling addons: default-storageclass, storage-provisioner
�  Configuring local host environment ...

Then:

sleep 60 #for minikube to start
kubectl run --image=wnameless/oracle-xe-11g-r2 oracle-db
watch -d kubectl get pods -A

After about 20-30 seconds of oracle-db deployment.

kubectl get pods will start timing out
Error from server: etcdserver: request timed out

kube-controller-manager will fail then kube-scheduler will fail. (edited)

Curiously, I was not able to reproduce this on hyperkit:

minikube start --memory 20000  --driver=hyperkit --cpus 4                                                                                          
kubectl run --image=wnameless/oracle-xe-11g-r2 oracle-db  

Oracle has been running for 17 minutes without issues:
