在服务中发出http请求时，我收到此响应。

这是登录组件

export class LoginComponent {
  credentials: Credentials;

  constructor(
    private auth: AuthService,
    @Inject(UserService) private userService: UserService,
    @Inject(HttpClient) private http: HttpClient,
    private auth0: Auth0Service
  ) {}

  onLogin(credentials) {
    const sendReq = this.userService.login(credentials);
}

我在App.module的提供程序中添加了UserService

这是UserService

@Injectable()
export class UserService {
  constructor(
    @Inject(Auth0Service) private authService: Auth0Service,
    protected http: HttpClient // @Inject(HttpClient) protected http: HttpClient
  ) {}
  login(credentials): Observable<any> {
    console.log(credentials);
    console.log(credentials.username);
    this.http
      .post("http://localhost:3000/api/Users/login", {
        username: credentials.username,
        password: credentials.password
      })
      .subscribe(
        data => {
          console.log(data);
        },
        err => {
          console.log("Something went wrong!");
          console.log(err); …

我已经在 Kubernetes 上设置了一个 Node 应用程序。我正在运行一个副本，并且我希望在更新映像时停机时间为 0。我set Image在 Kubernetes 上更新了我的 Pod 。

'set', 'image', 'deployment/dev-web'

这是我的 YAML 文件

apiVersion: extensions/v1beta1

    deployment.kubernetes.io/revision: "2"

我想要回滚我的 Pod 部署。我正在set ImageCI 环境中使用更新我的 pod。当我将 Deployment/web 文件上的 maxUnavailable 设置为 1 时，我会出现停机情况。但是当我将 maxUnavailable 设置为 0 时，pod 不会被替换，容器/应用程序也不会重新启动。

另外，我在 Kubernetes 集群中有一个节点，这是它的信息

    Allocated resources:
      (Total limits may be over 100 percent, i.e., overcommitted.)
      CPU Requests  CPU Limits  Memory Requests  Memory Limits
      ------------  ----------  ---------------  -------------

    Events:         <none>

这是完整的 YAML 文件。我确实有就绪探针组。
