mongodb - mongo-express 不是以 docker-compose 文件开头

Question

下面是我的 docker-compose.yml 文件。

version: '3.1'
services:
  mongodb:
    image: mongo
    ports: 
      - 27017:27017
    environment:
      - MONGO_INITDB_ROOT_USERNAME=root
      - MONGO_INITDB_ROOT_PASSWORD=admin
  mongo-express:
    image: mongo-express
    ports:
      - 8081:8081
    environment:
      - ME_CONFIG_MONGODB_ADMINUSERNAME=root
      - ME_CONFIG_MONGODB_ADMINPASSWORD=admin
      - ME_CONFIG_MONGODB_SERVER=mongodb
    depends_on:
      - mongodb
    restart: on-failure

我遇到错误:

Could not connect to database using connectionString: mongodb://root:admin@mongodb:27017/" in mongo-express. PFA-1The root user is created after error shown in mongo-express. PFA-2is the issue because mongo-express executed before mongodb?

Answer 1

对我来说，正是这一部分让 mongo express 开始了:

mongo-express:
    image: mongo-express
    restart: always
    ...
