Kubernetes集群环境搭建on Centos7

https://docs.docker.com/linux/

CentOS裸机安装

http://kubernetes.io/v1.1/docs/getting-started-guides/centos/centos_manual_config.html

依赖环境：

CentOS7.1

Docker 1.8.2

Kubernetes: 1.2.0

Golang: 1.4.2

etcd

两台机器：

centos-master 10.10.3.184

centos-minion 10.10.3.185

全是用yum方式安装

安装Docker、etcd、kubernates

yum update

配置virt7-docker-common-testing源

---

[virt7-docker-common-testing]

name=virt7-testing
baseurl=http://cbs.centos.org/repos/virt7-docker-common-testing/x86_64/os/

gpgcheck=0

---

yum -y install --enablerepo=virt7-docker-common-testing kubernetes

yum -y install etcd galang docker

 centos-master运行kubernetes三个组件：apiserver、scheduler、controller-manager，相关配置项也只涉及这三块。

for SERVICES in etcd kube-apiserver kube-controller-manager kube-scheduler; do 
    systemctl restart $SERVICES
    systemctl enable $SERVICES
    systemctl status $SERVICES 

done

centos-minion运行kubernetes的两个组件：proxy、kubelet。

需要配置/etc/kubernetes/config

###
# kubernetes system config
#
# The following values are used to configure various aspects of all
# kubernetes services, including
#
#   kube-apiserver.service
#   kube-controller-manager.service
#   kube-scheduler.service
#   kubelet.service
#   kube-proxy.service
# logging to stderr means we get it in the systemd journal
KUBE_LOGTOSTDERR="--logtostderr=true"

# journal message level, 0 is debug
KUBE_LOG_LEVEL="--v=0"

# Should this cluster be allowed to run privileged docker containers
KUBE_ALLOW_PRIV="--allow-privileged=false"

# How the controller-manager, scheduler, and proxy find the apiserver
KUBE_MASTER="--master=http://centos-master:8080"

# Comma separated list of nodes in the etcd cluster

KUBE_ETCD_SERVERS="--etcd-servers=http://localhost:2379"

for SERVICES in kube-proxy kubelet docker; do 
    systemctl restart $SERVICES
    systemctl enable $SERVICES
    systemctl status $SERVICES
