MongoDB and Mongo Express in Docker Compose

It took me some time to get that I coulnd’t use ME_CONFIG_MONGODB_URL to connect to my Mongo database so I thought I make a post so I’ll remember until next time.

First, let’s see how it is done in docker compose (docker-compose.yml).

version: '3.8'
services:
  mongo:
    image: mongo
    restart: always
    ports:
    - '27017:27017'
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example

  mongo-express:
    image: mongo-express
    restart: always
    ports:
      - 8081:8081
    environment:
      ME_CONFIG_MONGODB_ADMINUSERNAME: root
      ME_CONFIG_MONGODB_ADMINPASSWORD: example
      ME_CONFIG_MONGODB_SERVER: mongo
      ME_CONFIG_BASICAUTH_USERNAME: root
      ME_CONFIG_BASICAUTH_PASSWORD: example

That’s all, then when we run compose up we will create these containers and can go to http://localhost:8081/ to administrate our mongodb which is running the default port 27017 on localhost.
