resources: 
  # We usually recommend not to specify default resources and to leave this as a conscious
  # choice for the user. This also increases chances charts run on environments with little
  # resources, such as Minikube. If you do want to specify resources, uncomment the following
  # lines, adjust them as necessary, and remove the curly braces after 'resources:'.

# 测试打包
cd ..
helm lint ./myapp
helm package myapp/

# 创建代理，注意这里需要在 myapp-0.0.1.tgz  同级上执行，这里会启动一个web服务，端口为 8879
helm serve

# 新开一个终端，安装
helm install --name myapp1 local/myapp

# 测试，访问 ClusterIP
curl 10.102.91.53
#运行结果，正常：
Hello MyApp | Version: v1 | <a href="hostname.html">Pod Name</a>

# 查看 myapp1 的状态
helm status myapp1
