Kubernetes cookbook

Kubernetes cookbook that let you easy to deploy Kubernetes environment on RHEL/CentOS 7.x.

Intro

You should at least give below information:

• Etcd server address list

The Etcd server and Kubernetes master can be located on same node, a list usually only contains one ip address which is the Kubernetes master's ip address.

• Kubernetes master ip address

The Kubernetes master ip address, a string.

• Kubernetes minion ip address list and the interface where the IP is located on

The ip address list and interface(eth0, eth1...).

Quick start

Suppose your Kubernetes nodes are(You should make the nodes' hostname resolvable):

Role	Hostname	Interface	IP Address
Kube Master	kuber-master	eth0	192.168.122.10
Kube Minion	kuber-minion1	eth0	192.168.122.11
Kube Minion	kuber-minion2	eth0	192.168.122.12
Kube Minion	kuber-minion3	eth0	192.168.122.13

Checkout code:

# git clone https://github.com/chenzhiwei/kubernetes-cookbook kubernetes
# vim kubernetes/environments/kubernetes.json

The sample environments/kubernetes.json file content:

{
  "name": "kubernetes",
  "override_attributes": {
    "kube": {
      "api": {
        "host": "192.168.122.10"
      },
      "kubelet": {
        "machines": ["192.168.122.11", "192.168.122.12", "192.168.122.13"]
      },
      "interface": "eth0"
    },
    "etcd": {
      "host": ["192.168.122.10"]
    }
  }
}

Upload the Kubernetes role/environment/cookbook to Chef server:

# knife role from file roles/*.json
# knife environment from file environments/kubernetes.json
# knife cookbook upload kubernetes

Start boostraping your nodes:

# knife bootstrap 192.168.122.10 -E kubernetes -r 'role[kubernetes-etcd],role[kubernetes-master]'
# knife bootstrap 192.168.122.11 -E kubernetes -r 'role[kubernetes-minion]'
# knife bootstrap 192.168.122.12 -E kubernetes -r 'role[kubernetes-minion]'
# knife bootstrap 192.168.122.13 -E kubernetes -r 'role[kubernetes-minion]'

Login Kubernetes master:

# kubecfg list minions
