##Deploy a production ready kubernetes cluster
|
||||
|
||||
If you have questions, you can [invite yourself](https://slack.kubespray.io/) to **chat** with us on Slack! [](https://kubespray.slack.com)
|
||||
|
||||
- Can be deployed on **AWS, GCE, 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 <br>
|
||||
**vagrant** by simply running `vagrant up` (for tests purposes) <br>
|
||||
|
||||
|
||||
* [Requirements](#requirements)
|
||||
* [Getting started](docs/getting-started.md)
|
||||
* [Vagrant install](docs/vagrant.md)

Versions
|
||||
--------------
|
||||
|
||||
[kubernetes](https://github.com/kubernetes/kubernetes/releases) v1.3.0 <br>
|
||||
[etcd](https://github.com/coreos/etcd/releases) v3.0.1 <br>
|
||||
[calicoctl](https://github.com/projectcalico/calico-docker/releases) v0.20.0 <br>

[docker](https://www.docker.com/) v1.10.3 <br>
|
||||
|
||||
|
||||
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
|
||||
* **Copy your ssh keys** to all the servers part of your inventory.
|
||||
* **Ansible v2.x and python-netaddr**
|
||||
|
||||
|
||||
## Network plugins
|
||||
You can choose between 3 network plugins. (default: `flannel` with vxlan backend)
|
||||
|
||||
* [**flannel**](docs/flannel.md): gre/vxlan (layer 2) networking.
|
||||
|
||||
* [**calico**](docs/calico.md): bgp (layer 3) networking.
|
||||
|
||||
* **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`

Kargo's roadmap
|
||||
=================
|
||||
|
||||
### Self deployment (pull-mode) [#320](https://github.com/kubespray/kargo/issues/320)
|
||||
- the playbook would install and configure docker and the etcd cluster [#321](https://github.com/kubespray/kargo/issues/321)
|
||||
- the following data would be inserted into etcd: certs,tokens,users,inventory,group_vars.
|
||||
- a "kubespray" container would be deployed (kargo-cli, ansible-playbook, kpm)
|
||||
- to be discussed, a way to provide the inventory
|
||||
- **self deployment** of the node
|
||||
|
||||
### Provisionning and cloud providers
|
||||
- Terraform to provision instances on **GCE, AWS, Openstack, Digital Ocean, Azure**
|
||||
- On AWS autoscaling, multi AZ
|
||||
- On Azure autoscaling, create loadbalancer [#297](https://github.com/kubespray/kargo/issues/297)
|
||||
- On GCE be able to create a loadbalancer automatically (IAM ?) [#280](https://github.com/kubespray/kargo/issues/280)
|
||||
- **TLS boostrap** support for kubelet [#234](https://github.com/kubespray/kargo/issues/234)
|
||||
(related issues: https://github.com/kubernetes/kubernetes/pull/20439 <br>
|
||||
https://github.com/kubernetes/kubernetes/issues/18112)
|
||||
|
||||
### Tests
|
||||
- Run kubernetes e2e tests
|
||||
- migrate to jenkins
|
||||
(a test is currently a deployment on a 3 node cluste, testing k8s api, ping between 2 pods)
|
||||
- Full tests on GCE per day (All OS's, all network plugins)
|
||||
- trigger a single test per pull request
|
||||
- single test with the Ansible version n-1 per day
|
||||
- Test idempotency on on single OS but for all network plugins/container engines
|
||||
- single test on AWS per day
|
||||
- test different achitectures :
|
||||
- 3 instances, 3 are members of the etcd cluster, 2 of them acting as master and node, 1 as node
|
||||
- 5 instances, 3 are etcd and nodes, 2 are masters only
|
||||
- 7 instances, 3 etcd only, 2 masters, 2 nodes
|
||||
- test scale up cluster: +1 etcd, +1 master, +1 node
|
||||
|
||||
### Lifecycle
|
||||
- Drain worker node when upgrading k8s components in a worker node. [#154](https://github.com/kubespray/kargo/issues/154)
|
||||
- Drain worker node when shutting down/deleting an instance
|
||||
|
||||
### Networking
|
||||
- romana.io support [#160](https://github.com/kubespray/kargo/issues/160)
|
||||
- Configure network policy for Calico. [#159](https://github.com/kubespray/kargo/issues/159)
|
||||
- Opencontrail
|
||||
- Canal
|
||||
|
||||
### High availability
|
||||
- (to be discussed) option to set a loadbalancer for the apiservers like ucarp/packemaker/keepalived
|
||||
While waiting for the issue [kubernetes/kubernetes#18174](https://github.com/kubernetes/kubernetes/issues/18174) to be fixed.
|
||||
|
||||
### Kargo-cli
|
||||
- Delete instances
|
||||
- `kargo vagrant` to setup a test cluster locally
|
||||
- switch to Terraform instead of Ansible for provisionning
|
||||
|
||||
### Kargo API
|
||||
- Perform all actions through an **API**
|
||||
- Store inventories / configurations of mulltiple clusters
|
||||
- make sure that state of cluster is completely saved in no more than one config file beyond hosts inventory
|
||||
|
||||
### Addons (with kpm)
|
||||
Include optionals deployments to init the cluster:
|
||||
##### Monitoring
|
||||
- Heapster / Grafana ....
|
||||
- **Prometheus**
|
||||
|
||||
##### Others
|
||||
|
||||
##### Dashboards:
|
||||
- kubernetes-dashboard
|
||||
- Fabric8
|
||||
- Tectonic
|
||||
- Cockpit
|
||||
|
||||
##### Paas like
|
||||
- Openshift Origin
|
||||
- Openstack
|
||||
- Deis Workflow
|
||||
|
||||
### Others
|
||||
- remove nodes (adding is already supported)
|
||||
- being able to choose any k8s version (almost done)
|
||||
- **rkt** support [#59](https://github.com/kubespray/kargo/issues/59)
|
||||
- Review documentation (split in categories)
|
||||
- **consul** -> if officialy supported by k8s
|
||||
- flex volumes options (e.g. **torrus** support) [#312](https://github.com/kubespray/kargo/issues/312)
|
||||
- Clusters federation option (aka **ubernetes**) [#329](https://github.com/kubespray/kargo/issues/329)
