集群操作方法单元测试

apps/cluster/impl/impl_test.go

加载依赖

var (
  impl cluster.Service
  ctx  = context.Background()
)

func init() {
  tools.DevelopmentSetup()
  impl = app.GetInternalApp(cluster.AppName).(cluster.Service)
}

测试创建集群信息

func TestCreateCluster(t *testing.T) {
  req := cluster.NewCreateClusterRequest()
  req.Vendor = "腾讯云"
  req.Region = "上海"
  req.Name = "生产环境"

  kubeConf, err := tools.ReadFile("F:\\go\\project\\0-shizhanxiangmu\\mpaas\\test\\kube_config.yml")
  if err != nil {

  req.KubeConfig = string(kubeConf)
  ins, err := impl.CreateCluster(ctx, req)
  if err != nil {
    t.Fatal(err)

  t.Log(ins)
