+# ubuntu 16.04 openstack ocata neutron controler node
+
+## How to build the docker image.
+```
+docker  build . -t="hpc/neutroncontroller"
+```
+
+## How to bootstrap the service.
+Before we can take the container into service we need accounts in keystone.
+We also need an initial database. Both of these tasks are performed by the bootstrap script.
+```
+docker run --rm --it --add-host="controller:<keystone_ip>" hpc/neutroncontroler /etc/bootstrap.sh
+```
+
+## How to run
+This image needs a lot of environment variables. It should be run via the `hpc-cloud` ansible repository.
+
+
+## Notes
+This image is designed to be deployed from the [hpc-cloud repo](https://git.webhosting.rug.nl/HPC/hpc-cloud)
+The -p option is added to the run command to make the container accessible from (containers on ) other hosts than the container host.
