Gitlab 完成k8s的CD

使用gitlab完成k8s的CD的上线操作

• 1.创建k8s的编排yaml，放在仓库中

• 2.写CD脚本

• 3.在web界面上进行操作，添加参数

配置参数的地方：

stages:
- deploy

deploy_dev:
when: manual

 - master
 - /^feature\/.*$/
 - /^feature-.*$/
tags:
 - kun
script:
 - envsubst < storm.yaml  | kubectl apply -f  -

variables:
 IMAGE: harbor.example.com/default/hello-world-$CI_COMMIT_REF_SLUG:$CI_COMMIT_SHA
 SERVICE_NAME: hello-world-$CI_COMMIT_REF_SLUG
 NAMESPACE: default
 NODE_ENV: development
