# Magnum openSUSE K8s driver
This is openSUSE Kubernetes driver for Magnum, which allow to deploy Kubernetes cluster on openSUSE.
## Installation
### 1. Install the openSUSE K8s driver in Magnum
- To install the driver, from this directory run:
`python ./setup.py install`
### 2. Enable driver in magnum.conf
enabled_definitions = ...,magnum_vm_opensuse_k8s
### 2. Restart Magnum
Both Magnum services has to restarted `magnum-api` and `magnum-conductor`

A Kubernetes cluster with Heat
==============================
These [Heat][] templates will deploy a [Kubernetes][] cluster that
supports automatic scaling based on CPU load.
[heat]: https://wiki.openstack.org/wiki/Heat
[kubernetes]: https://github.com/GoogleCloudPlatform/kubernetes
The cluster uses [Flannel][] to provide an overlay network connecting
pods deployed on different minions.
[flannel]: https://github.com/coreos/flannel
## Requirements
### OpenStack
These templates will work with the Kilo version of Heat. They *may*
work with Juno as well as soon as [#1402894][] is resolved.
[#1402894]: https://bugs.launchpad.net/heat/+bug/1402894
### Guest image
These templates will work with either CentOS Atomic Host or Fedora 21
Atomic or OpenSUSE Atomic.
You can enable docker registry v2 by setting the "registry_enabled"
parameter to "true".
## Creating the stack
Creating an environment file `local.yaml` with parameters specific to
your environment:
parameters:
ssh_key_name: testkey
external_network: public
dns_nameserver: 192.168.200.1
server_image: openSUSELeap42.1-jeos-k8s
registry_enabled: true
registry_username: username
registry_password: password
registry_domain: domain
registry_trust_id: trust_id
registry_auth_url: auth_url
registry_region: region
registry_container: container
And then create the stack, referencing that environment file:
heat stack-create -f kubecluster.yaml -e local.yaml my-kube-cluster
You must provide values for:
- `ssh_key_name`
- `server_image`
If you enable docker registry v2, you must provide values for:
- `registry_username`
- `registry_password`
- `registry_domain`
- `registry_trust_id`
- `registry_auth_url`
- `registry_region`
- `registry_container
## Interacting with Kubernetes
You can get the ip address of the Kubernetes master using the `heat
output-show` command:
$ heat output-show my-kube-cluster kube_masters
"192.168.200.86"
You can ssh into that server as the `minion` user:
$ ssh minion@192.168.200.86
And once logged in you can run `kubectl`, etc:
$ kubectl get minions
NAME LABELS STATUS
10.0.0.4 <none> Ready
You can log into your minions using the `minion` user as well. You
can get a list of minion addresses by running:
$ heat output-show my-kube-cluster kube_minions
[
"192.168.200.182"
]
You can get the docker registry v2 address:
$ heat output-show my-kube-cluster registry_address
localhost:5000
## Testing
The templates install an example Pod and Service description into
`/etc/kubernetes/examples`. You can deploy this with the following
commands:
$ kubectl create -f /etc/kubernetes/examples/web.service
$ kubectl create -f /etc/kubernetes/examples/web.pod
This will deploy a minimal webserver and a service. You can use
`kubectl get pods` and `kubectl get services` to see the results of
these commands.

# not contain "_" (underscore) because it will be used in the
