我正在开发一个具有两个容器的Web应用程序，第一个容器是在flask中开发的Web应用程序，第二个是mongodb映像。我想同时运行它们，所以我编写了以下docker-compose.yml
- (void)scene:(UIScene *)scene willConnectToSession:(UISceneSession *)session options:(UISceneConnectionOptions *)connectionOptions {
// Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
// If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
// This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.windowScene = (UIWindowScene *)scene;
self.viewController = [[ViewController alloc] init];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:self.viewController];
self.window.rootViewController = navController;
[self.window makeKeyAndVisible];
}
首先我运行version: '3.7'
services:
flask:
build: .
depends_on:
- mongo
ports:
- "5000:5000"
volumes:
- ./flask:/flask
mongo:
image: mongo:latest
ports:
- "27017:27017"
volumes:
- ./dump:/dump # data
- ./datos_db:/data/db # persistance database
时没有错误，然后在运行$docker-compose build时出现以下错误：
$ docker-compose up据我了解，容器等待太多时间才能mongo_1 | 2019-10-30T16:18:47.420+0000 error connecting to host: could not connect to server: server selection error: server selection timeout

practica4_mongo_1 exited with code 1
打开并决定关闭。 （我也尝试使用端口49155）
有什么我想念的东西，这使我的docker崩溃了吗？
