环境描述：
192.168.0.63为k8s集群主节点，保证你的集群里dns与ingress已经安装了

编译打包就不叙述了，主要流程就是：
编译打包-> build镜像 -> 上传镜像到私服 -> 使用ansible-playbook拷贝模板文件到集群主节点 -> 更改模板文件 -> create pod，service，ingress

模板yaml文件
templet.yaml用来创建pod，service的文件，需要替换里面的项目名和环境名（#不能出现下划线）

[root@jenkins-master templet]# cat templet.yaml

Ingress文件是相当与nginx一样的功能

[root@jenkins-master templet]# cat ingress_templet.yaml 
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: projectname-environment-ingress
  namespace: default
spec:
  rules:
  - host: environment-projectname.xxxx.com
    http:
      paths:
      - path: /
        backend:
          serviceName: projectname-environment-service
          servicePort: 80

#
#
#

#
#
#

#

kubectl create -f test.yaml --record

#
#

#

kubectl create -f ingress-test.yaml

#

#

#

curl -v http://192.168.120.17 -H 'host: dev-platform-business.xxxx.com'

//如果是测试写上host   192.168.120.17 dev-platform-business.xxxx.com

#
#
#

#
#

kubectl rollout history deployment                                                             //查看deployment更新记录历史
kubectl rollout history deployment/sk-platform-business-dev-deployment

#
#

kubectl set image deployment/sk-platform-business-dev-deployment sk-platform-business-dev-pod=basic-repository.xxxx.com/xxxx/sk_platform_center_dev:master
///更新指定deployment的镜像，可以通过此命令来更新发版

#
#

#
#

kubectl rollout undo deployment/sk-platform-business-dev-deployment --to-revision=1
//undo参数为回滚命令，所以在创建时--record参数很重要

#
#

#
#

//这个步骤在install_docker.yml已经添加此命令，但是Jenkins应该是不会显示，应该通过ansible命令在最后执行：

ansible 192.168.0.63 -m shell -a '/data/kubernetes/bin/kubectl rollout history deployment/sk-platform-business-dev-deployment'
