##Deploy a production ready kubernetes cluster
|
|
|
|
If you have questions, join us on the [kubernetes slack](https://slack.k8s.io), channel **#kargo**.
|
|
|
|
- Can be deployed on **AWS, GCE, Azure, OpenStack or Baremetal**
|
|
- **High available** cluster
|
|
- **Composable** (Choice of the network plugin for instance)
|
|
- Support most popular **Linux distributions**
|
|
- **Continuous integration tests**
|
|
|
|
|
|
To deploy the cluster you can use :
|
|
|
|
[**kargo-cli**](https://github.com/kubespray/kargo-cli) <br>
|
|
**Ansible** usual commands and [**inventory builder**](https://github.com/kubernetes-incubator/kargo/blob/master/contrib/inventory_builder/inventory.py) <br>
|
|
**vagrant** by simply running `vagrant up` (for tests purposes) <br>

Supported Linux distributions
|
|
===============
|
|
|
|
* **Container Linux by CoreOS**
|
|
* **Debian** Jessie
|
|
* **Ubuntu** 16.04
|
|
* **CentOS/RHEL** 7
|
|
|
|
Note: Upstart/SysV init based OS types are not supported.
|
|
|
|
Versions of supported components
|
|
--------------------------------
|
|
|
|
[kubernetes](https://github.com/kubernetes/kubernetes/releases) v1.5.1 <br>
|
|
[etcd](https://github.com/coreos/etcd/releases) v3.0.6 <br>
|
|
[flanneld](https://github.com/coreos/flannel/releases) v0.6.2 <br>
|
|
[calicoctl](https://github.com/projectcalico/calico-docker/releases) v0.23.0 <br>
|
|
[canal](https://github.com/projectcalico/canal) (given calico/flannel versions) <br>
|
|
[weave](http://weave.works/) v1.8.2 <br>
|
|
[docker](https://www.docker.com/) v1.12.5 <br>
|
|
[rkt](https://coreos.com/rkt/docs/latest/) v1.21.0 <br>
|
|
|
|
Note: rkt support as docker alternative is limited to control plane (etcd and
|
|
kubelet). Docker is still used for Kubernetes cluster workloads and network
|
|
plugins' related OS services. Also note, only one of the supported network
|
|
plugins can be deployed for a given single cluster.
|
|
|
|
Requirements
|
|
--------------
|
|
|
|
* The target servers must have **access to the Internet** in order to pull docker images.
|
|
* The **firewalls are not managed**, you'll need to implement your own rules the way you used to.
|
|
in order to avoid any issue during deployment you should disable your firewall.
|
|
* The target servers are configured to allow **IPv4 forwarding**.
|
|
* **Copy your ssh keys** to all the servers part of your inventory.
|
|
* **Ansible v2.2 (or newer) and python-netaddr**
|
|
|
|
|
|
## Network plugins
|
|
You can choose between 4 network plugins. (default: `flannel` with vxlan backend)
|
|
|
|
* [**flannel**](docs/flannel.md): gre/vxlan (layer 2) networking.
|
|
|
|
* [**calico**](docs/calico.md): bgp (layer 3) networking.
|
|
|
|
* [**canal**](https://github.com/projectcalico/canal): a composition of calico and flannel plugins.
|
|
|
|
* **weave**: Weave is a lightweight container overlay network that doesn't require an external K/V database cluster. <br>
|
|
(Please refer to `weave` [troubleshooting documentation](http://docs.weave.works/weave/latest_release/troubleshooting.html)).
|
|
|
|
The choice is defined with the variable `kube_network_plugin`. There is also an
|
|
option to leverage built-in cloud provider networking instead.
|
|
See also [Network checker](docs/netcheck.md).
