在阿里云的ECS下（centos系统）安装k8s
相信部署过或者了解过k8s部署的同学都知道，k8s很好但是安装起来比较复杂，所以给大家整理了如下快捷的安装方法
1.yum install -y etcd kubernetes
2.vim /etc/sysconfig/docker
# 内容改为如下 OPTIONS='--selinux-enabled=false --insecure-registry gcr.io'
3.vim /etc/kubernetes/apiserver 去掉–admission-control中的ServiceAccount
4.systemctl start etcd.service
5.systemctl start docker
6.systemctl start kube-apiserver.service
7.systemctl start kube-controller-manager.service
8.systemctl start kube-scheduler.service
9.systemctl start kubelet.service
10.systemctl start kube-proxy.service
11.yum install python-rhsm-certificates
避免k8s下载镜像出错
12.运行wget http://mirror.centos.org/centos/7/os/x86_64/Packages/python-rhsm-certificates-1.19.10-1.el7_4.x86_64.rpm 手动下载
13.chmod +x python-rhsm-certificates-1.19.10-1.el7_4.x86_64.rpm
14.运行 rpm2cpio python-rhsm-certificates-1.19.10-1.el7_4.x86_64.rpm | cpio -iv --to-stdout /etc/rhsm/ca/redhat-uep.pem | tee /etc/rhsm/ca/redhat-uep.pem
15.运行 ll /etc/docker/certs.d/registry.access.redhat.com/redhat-ca.crt 指向正确
16.docker pull XXXX
17.编写yaml文件：
XXXX.yaml:
apiVersion: v1
kind: ReplicationController
metadata:
name: myname
labels:
name: myname
spec:
replicas: 2
selector:
name: myname
template:
metadata:
labels:
name: myname
spec:
containers:
- name: myname
image: helloWord
imagePullPolicy: IfNotPresent
ports:
- containerPort: 8080
18.kubectl create -f xxxxx.yaml
19.kubectl get rc
20.kubectl get pods
21.kubectl describe pod helloworld-7jpm5
22.kubectl logs helloworld-7jpm5
通过yum的安装方式可以很简单的安装，但是部分功能不支持
