-vagrant-k8s
-===========
-Scripts to create libvirt lab with vagrant and prepare some stuff for `k8s` deployment with `kargo`.
+[![Build Status](https://travis-ci.org/ansibl8s/setup-kubernetes.svg)](https://travis-ci.org/ansibl8s/setup-kubernetes)
+kubernetes-ansible
+========
 
+Install and configure a Multi-Master/HA kubernetes cluster including network plugin.
 
-Requirements
-============
+### Requirements
+Tested on **Debian Wheezy/Jessie** and **Ubuntu** (14.10, 15.04, 15.10).
+Should work on **RedHat/Fedora/Centos** platforms (to be tested)
+* The target servers must have access to the Internet in order to pull docker imaqes.
+* The firewalls are not managed, you'll need to implement your own rules the way you used to.
+* Ansible v1.9.x and python-netaddr
 
-* `libvirt`
-* `vagrant`
-* `vagrant-libvirt` plugin
-* `$USER` should be able to connect to libvirt (test with `virsh list --all`)
+### Components
+* [kubernetes](https://github.com/kubernetes/kubernetes/releases) v1.1.3
+* [etcd](https://github.com/coreos/etcd/releases) v2.2.2
+* [calicoctl](https://github.com/projectcalico/calico-docker/releases) v0.13.0
+* [flanneld](https://github.com/coreos/flannel/releases) v0.5.5
+* [docker](https://www.docker.com/) v1.9.1
 
-How-to
-======
+Quickstart
+-------------------------
+The following steps will quickly setup a kubernetes cluster with default configuration.
+These defaults are good for tests purposes.
 
-* Prepare the virtual lab:
+Edit the inventory according to the number of servers
+```
+[downloader]
+localhost ansible_connection=local ansible_python_interpreter=python2
 
-```bash
-export VAGRANT_POOL="10.100.0.0/16"
-git clone https://github.com/adidenko/vagrant-k8s
-cd vagrant-k8s
-vagrant up
+[kube-master]
+10.115.99.31
+
+[etcd]
+10.115.99.31
+10.115.99.32
+10.115.99.33
+
+[kube-node]
+10.115.99.32
+10.115.99.33
+
+[k8s-cluster:children]
+kube-node
+kube-master
 ```
 
-* Login to master node and deploy k8s with kargo:
-
-```bash
-vagrant ssh $USER-k8s-01
-# Inside your master VM run this:
-sudo su -
-./deploy-k8s.kargo.sh
+Run the playbook
 ```
+ansible-playbook -i inventory/inventory.cfg cluster.yml -u root
+```
+
+You can jump directly to "*Available apps, installation procedure*"
+
+
+Ansible
+-------------------------
+### Variables
+The main variables to change are located in the directory ```inventory/group_vars/all.yml```.
+
+### Inventory
+Below is an example of an inventory.
+Note : The bgp vars local_as and peers are not mandatory if the var **'peer_with_router'** is set to false
+By default this variable is set to false and therefore all the nodes are configure in **'node-mesh'** mode.
+In node-mesh mode the nodes peers with all the nodes in order to exchange routes.
+

+kube-node
+kube-master
+```
+
+### Playbook
+```
+---
+- hosts: downloader
+  sudo: no
+  roles:
+    - { role: download, tags: download }
+
+- hosts: k8s-cluster
+  roles:
+    - { role: kubernetes/preinstall, tags: preinstall }
+    - { role: docker, tags: docker }
+    - { role: kubernetes/node, tags: node }
+    - { role: etcd, tags: etcd }
+    - { role: dnsmasq, tags: dnsmasq }
+    - { role: network_plugin, tags: ['calico', 'flannel', 'network'] }
+
+- hosts: kube-master
+  roles:
+    - { role: kubernetes/master, tags: master }
+
+```
+
+### Run
+It is possible to define variables for different environments.
+For instance, in order to deploy the cluster on 'dev' environment run the following command.
+```
+ansible-playbook -i inventory/dev/inventory.cfg cluster.yml -u root
+```
+
+Kubernetes
+-------------------------
+### Multi master notes
+* You can choose where to install the master components. If you want your master node to act both as master (api,scheduler,controller) and node (e.g. accept workloads, create pods ...), 
+the server address has to be present on both groups 'kube-master' and 'kube-node'.
+
+* Almost all kubernetes components are running into pods except *kubelet*. These pods are managed by kubelet which ensure they're always running
+
+* For safety reasons, you should have at least two master nodes and 3 etcd servers
+
+* Kube-proxy doesn't support multiple apiservers on startup ([Issue 18174](https://github.com/kubernetes/kubernetes/issues/18174)). An external loadbalancer needs to be configured.
+In order to do so, some variables have to be used '**loadbalancer_apiserver**' and '**apiserver_loadbalancer_domain_name**' 
+ 
+
+### Network Overlay
+You can choose between 2 network plugins. Only one must be chosen.
+
+* **flannel**: gre/vxlan (layer 2) networking. ([official docs](https://github.com/coreos/flannel))
+
+* **calico**: bgp (layer 3) networking. ([official docs](http://docs.projectcalico.org/en/0.13/))
+
+The choice is defined with the variable '**kube_network_plugin**'
+
+### Expose a service
+There are several loadbalancing solutions.
+The one i found suitable for kubernetes are [Vulcand](http://vulcand.io/) and [Haproxy](http://www.haproxy.org/)
+
+My cluster is working with haproxy and kubernetes services are configured with the loadbalancing type '**nodePort**'.
+eg: each node opens the same tcp port and forwards the traffic to the target pod wherever it is located.
+
+Then Haproxy can be configured to request kubernetes's api in order to loadbalance on the proper tcp port on the nodes.
+
+Please refer to the proper kubernetes documentation on [Services](https://github.com/kubernetes/kubernetes/blob/release-1.0/docs/user-guide/services.md)
+
+### Check cluster status
+
+#### Kubernetes components
+
+* Check the status of the processes
+```
+systemctl status kubelet
+```
+
+* Check the logs
+```
+journalctl -ae -u kubelet
+```
+
+* Check the NAT rules
+```
+iptables -nLv -t nat
+```
+
+For the master nodes you'll have to see the docker logs for the apiserver
+```
+docker logs [apiserver docker id]
+```
+
+
+### Available apps, installation procedure
+
+There are two ways of installing new apps
+
+#### Ansible galaxy
+
+Additionnal apps can be installed with ```ansible-galaxy```.
+
+ou'll need to edit the file '*requirements.yml*' in order to chose needed apps.
+The list of available apps are available [there](https://github.com/ansibl8s)
+
+For instance it is **strongly recommanded** to install a dns server which resolves kubernetes service names.
+In order to use this role you'll need the following entries in the file '*requirements.yml*' 
+Please refer to the [k8s-kubedns readme](https://github.com/ansibl8s/k8s-kubedns) for additionnal info.
+```
+- src: https://github.com/ansibl8s/k8s-common.git
+  path: roles/apps
+  # version: v1.0
+
+- src: https://github.com/ansibl8s/k8s-kubedns.git
+  path: roles/apps
+  # version: v1.0
+```
+**Note**: the role common is required by all the apps and provides the tasks and libraries needed.
+
+And empty the apps directory
+```
+rm -rf roles/apps/*
+```
+
+Then download the roles with ansible-galaxy
+```
+ansible-galaxy install -r requirements.yml
+```
+
+#### Git submodules
+Alternatively the roles can be installed as git submodules.
+That way is easier if you want to do some changes and commit them.
+
+You can list available submodules with the following command:
+```
+grep path .gitmodules | sed 's/.*= //'
+```
+
+In order to install the dns addon you'll need to follow these steps
+```
+git submodule init roles/apps/k8s-common roles/apps/k8s-kubedns
+git submodule update
+```
+
+Finally update the playbook ```apps.yml``` with the chosen roles, and run it
+```
+...
+- hosts: kube-master
+  roles:
+    - { role: apps/k8s-kubedns, tags: ['kubedns', 'apps']  }
+...
+```
+
+```
+ansible-playbook -i inventory/inventory.cfg apps.yml -u root
+```
+
+
+#### Calico networking
+Check if the calico-node container is running
+```
+docker ps | grep calico
+```
+
+The **calicoctl** command allows to check the status of the network workloads.
+* Check the status of Calico nodes
+```
+calicoctl status
+```
+
+* Show the configured network subnet for containers
+```
+calicoctl pool show
+```
+
+* Show the workloads (ip addresses of containers and their located)
+```
+calicoctl endpoint show --detail
+```
+#### Flannel networking
+
+Congrats ! now you can walk through [kubernetes basics](http://kubernetes.io/v1.1/basicstutorials.html)
