Using CentOS 7
[stack@droctagon4 devstack]$ cat /etc/redhat-release
CentOS Linux release 7.3.1611 (Core)
Following the steps using video in this article
I clone devstack, and create a stack user...
Here's my local.conf
[stack@droctagon4 devstack]$ cat local.conf

And we need a dockerfile & and this simple python server
[stack@droctagon4 devstack]$ cat demo/Dockerfile
FROM alpine
RUN apk add --no-cache python bash openssh-client curl
COPY server.py /server.py
ENTRYPOINT ["python", "server.py"]
[stack@droctagon4 devstack]$ cat demo/server.py
import BaseHTTPServer as http
import platform
class Handler(http.BaseHTTPRequestHandler):
def do_GET(self):
self.send_response(200)
self.send_header('Content-Type', 'text/plain')
self.end_headers()
self.wfile.write("%s\n" % platform.node())
if __name__ == '__main__':
httpd = http.HTTPServer(('', 8080), Handler)
httpd.serve_forever()
Run ./stack.sh, and get a total run time, 2890 (about 50 minutes?)
This is your host IP address: 192.168.1.26
This is your host IPv6 address: ::1
Horizon is now available at http://192.168.1.26/dashboard
Keystone is serving at http://192.168.1.26/identity/

Getting pretty in the video until the VM...
[stack@droctagon4 devstack]$ source openrc

So I guess let's spin up something like what is shown.
[stack@droctagon4 devstack]$ curl -o /tmp/cirros.qcow2 http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img

[stack@droctagon4 devstack]$ nova boot --flavor m1.tiny --image cirros testvm
[stack@droctagon4 devstack]$ openstack subnet list --network private -c ID -c Name

Looks pretty close. Continuing on...
Sooooo... stiking again, no kubelet, huh?
[stack@droctagon4 devstack]$ kubectl get nodes
{ ...empty... }
And in screen 28 for kubelet... Just an empty prompt.
[stack@droctagon4 devstack]$
And of course if I try to run a pod, it fails to schedule.
[stack@droctagon4 devstack]$ kubectl get nodes
[stack@droctagon4 devstack]$ kubectl run demo --image=demo:demo
