Mongo Express服务器在http://0.0.0.0:8081上监听

Question

version: "3.3"
services:
    mongodb:
        image: mongo:latest
        container_name: "mongo"
        environment:
            MONGO_INITDB_ROOT_USERNAME: root
            MONGO_INITDB_ROOT_PASSWORD: rootpassword
        ports:
            - 27017:27017
    mongo-express:
        image: mongo-express:latest
        container_name: mongoexpressweb
        environment:
            - ME_CONFIG_OPTIONS_EDITORTHEME=ambiance
            - ME_CONFIG_MONGODB_ENABLE_ADMIN=true
            - ME_CONFIG_MONGODB_AUTH_DATABASE=admin
            - ME_CONFIG_MONGODB_AUTH_USERNAME=root
            - ME_CONFIG_MONGODB_AUTH_PASSWORD=rootpassword
            - ME_CONFIG_MONGODB_ADMINUSERNAME=root
            - ME_CONFIG_MONGODB_ADMINPASSWORD=rootpassword
            - ME_CONFIG_BASICAUTH_USERNAME=root
            - ME_CONFIG_BASICAUTH_PASSWORD=root
        ports:
            - 8081:8081
        links:
            - mongodb
        depends_on:
            - mongodb

我已经对我的docker-compose.yaml文件进行了类似的编码。之后两者都会运行。然而，mongo-express处于403禁止错误。当我在visual studio代码中检查视图日志时。我看到了这个错误：

docker-compose.yml

version: "3.3"

services:
    mongodb:
        image: mongo:latest
        container_name: "mongo"
        environment:
            MONGO_INITDB_ROOT_USERNAME: root
            MONGO_INITDB_ROOT_PASSWORD: rootpassword
        ports:
            - 27017:27017
        networks:       # Add this <--
            - random    # Add this <--
    mongo-express:
        image: mongo-express:latest
        container_name: mongoexpressweb
        environment:
            - ME_CONFIG_OPTIONS_EDITORTHEME=ambiance
            - ME_CONFIG_MONGODB_ENABLE_ADMIN=true
            - ME_CONFIG_MONGODB_AUTH_DATABASE=admin
            - ME_CONFIG_MONGODB_AUTH_USERNAME=root
            - ME_CONFIG_MONGODB_AUTH_PASSWORD=rootpassword
            - ME_CONFIG_MONGODB_ADMINUSERNAME=root
            - ME_CONFIG_MONGODB_ADMINPASSWORD=rootpassword
            - ME_CONFIG_BASICAUTH_USERNAME=root
            - ME_CONFIG_BASICAUTH_PASSWORD=root
        ports:
            - 8081:8081
        #links:         # you can remove this, deprecated
        #    - mongodb  # you can remove this, deprecated
        depends_on:
            - mongodb
        networks:       # Add this <--
            - random    # Add this <--

networks:   # Add this <--
    random: # Add this <--

现在，也许你在Visual studio上遇到了一个错误，它试图在localhost上连接，但你需要给出容器IP而不是localhost，才能找到它：

docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container_name_or_id

以防万一，在您提供的日志上，mongo-express成功连接到mongoDB (最后)
