Ansible Recipes to Install Kubernetes on CloudStack
=====================================

Basic recipes using the ansible cloudstack module to create ssh keys, sec group etc and deploy [Kubernetes](http://kubernetes.io) on [CoreOS](http://coreos.com).

Prerequisites
-------------

You will need Ansible and [cs](https://github.com/exoscale/cs) :)

$ sudo apt-get install -y python-pip libssl-dev
    $ sudo pip install cs
    $ sudo pip install sshpubkeys
    $ sudo apt-get install software-properties-common
    $ sudo apt-add-repository ppa:ansible/ansible
    $ sudo apt-get update
    $ sudo apt-get install ansible

Setup cs
--------

Create a `~/.cloudstack.ini` file with your creds and cloudstack endpoint:

[cloudstack]
    endpoint = <cloudstackapiendpoint>
    key = <apiaccesskey> 
    secret = <apisecretkey> 
    method = post

We need to use the http POST method to pass the userdata to the coreOS instances.

We can also use variables:

CLOUDSTACK_ENDPOINT=<cloudstackapiendpoint>
    CLOUDSTACK_KEY=<apiaccesskey>
    CLOUDSTACK_SECRET=<apisecretkey>
    CLOUDSTACK_METHOD=post

On CloudStack server you have to install libselinux-python

yum install libselinux-python

Clone the repository
---------------

$ git clone https://github.com/apachecloudstack/k8s
    $ cd ansible-kubernetes

Create a Kubernetes cluster
---------------------------

$ ansible-playbook k8s.yml

Some variables can be edited in the `k8s.yml` file.
This will start a Kubernetes master node and a number of compute nodes.
This is all setup via coreOS instances and passing userdata.

Check the tasks and templates in `roles/k8s`

If you retrieve an error during the ssh key copy:

"msg": "file (/root/.ssh/id_rsa_k8s) is absent, cannot continue",

Please run the Playbook a second time [(related issue)](https://github.com/apachecloudstack/k8s/issues/5)

Create etcd cluster
-------------------

That's a bonus to this work, there is a playbook to create an independent etcd cluster.

$ ansible-playbook etcd.yml

Edit some of the variables in the `etcd.yml` file directly.

Important Notice
-------------

If you want to run it on a CloudStack environment with VMware ESX hosts cluster. You have to comment the lines refer to secgroups and secgroup_rules (specific to KVM) :
    k8s.yml
    k8s/tasks/main.yml
    k8s/tasks/create_vm.yml
    etcd.yml
    etcd/tasks/main.yml

k8s
