mysql pod remains in pending state

[manohar]

I have recently installed Seldon on a macbook pro running Yosemite 10.10.5 with 8 GB ram. I am trying to run Seldon locally on my laptop.

After following through the instructions on this page, http://docs.seldon.io/install.html, I ran the seldon-up script. After a few minutes, the script exited with this error: 

The connection to the server 192.168.99.100:8443 was refused - did you specify the right host or port?

Has anyone seen this error?

I noticed from the messages that the mysql pod was in pending state. And the documentation suggests that it could be due to lack of resources on my machine: I guess that means memory. With 8 GB ram, I did not expect that to be a problem.

Anyway, I re-started with a clean slate and ran the following commands:

$ minikube start --memory=6000

Starting local Kubernetes cluster...

Kubectl is now configured to use the cluster.

$ kubectl create -f /Users/manohar/seldon-server/kubernetes/conf/mysql.json

pod "mysql" created

service "mysql" created

After 26 minutes, the mysql pod is still in pending state. 

$ kubectl get pods

NAME      READY     STATUS    RESTARTS   AGE

mysql     0/1       Pending   0          26m

What could be the problem? There is enough memory available as also disk space. The kubectl version is 1.5.1 and minikube version is 0.14.0

I was able to find the problem and am summarizing the issue, in case someone else faces the same problem.

I had run the "minikube start" command a few days ago for some testing purposes and it had created a node. The node persists even after we stop minikube using the "minikube stop" command.

I removed the node using the "minikube delete" command. This deleted the node.

Subsequently, on running the commands listed in my previous post, I was able to get the  mysql pod up and running.
