Use terminal

Install mongo docker image

docker run -d \
-p27017:27017 \
--name mongo \
--network mongo-network \
-e MONGO_INITDB_ROOT_USERNAME=admin \
-e MONGO_INITDB_ROOT_PASSWORD=password \
mongo

Install mongo-express docker image

docker run -d \
-p8081:8081 \
--name mongo-express \
--network mongo-network \
-e ME_CONFIG_MONGODB_ADMINUSERNAME=admin \
-e ME_CONFIG_MONGODB_ADMINPASSWORD=password \
-e ME_CONFIG_MONGODB_URL="mongodb://admin:password@mongo:27017/" \
mongo-express

• Make sure the mongo and mongo-express username and password are the same.

Use name.yaml file

.env file setup

MONGO_USERNAME=admin
MONGO_PASSWORD=password
MONGO_URL=mongodb://<username>:<password>@localhost:27017
MONGO_DB=database-name

name.yaml file setup

# docker compose -f mongodb.yaml up -d => start the containers in detached mode
# docker compose -f mongodb.yaml down => stop the containers
version: "3.8" # optional, specify the version of the docker-compose file format

services:
    mongo:
        image: mongo
        ports:
            - "27017:27017"
        environment:
            - MONGO_INITDB_ROOT_USERNAME=${MONGO_USERNAME} # MONGO_INITDB_ROOT_USERNAME: username
            - MONGO_INITDB_ROOT_PASSWORD=${MONGO_PASSWORD}
            - MONGO_INITDB_DATABASE=${MONGO_DB}
        volumes:
            - /c/Users/path-dir/Desktop/data:/data/db # persist data in a named volume (host_directory:/container_directory) (mongodb data path = /data/db)

    mongo-express:
        image: mongo-express
        ports:
            - "8081:8081"
        depends_on:
            - mongo
        environment:
            - ME_CONFIG_MONGODB_ADMINUSERNAME=${MONGO_USERNAME}
            - ME_CONFIG_MONGODB_ADMINPASSWORD=${MONGO_PASSWORD}
