Step 1: Create docker network

docker network create mongo-network 

Step 2: Start mongodb

docker run -d -p 27017:27017 -e MONGO_INITDB_ROOT_USERNAME=admin -e MONGO_INITDB_ROOT_PASSWORD=password --name mongodb --net mongo-network mongo    

Step 3: Start mongo-express

docker run -d -p 8081:8081 -e ME_CONFIG_MONGODB_ADMINUSERNAME=admin -e ME_CONFIG_MONGODB_ADMINPASSWORD=password --net mongo-network --name mongo-express -e ME_CONFIG_MONGODB_SERVER=mongodb mongo-express   

NOTE: creating docker-network in optional. You can start both containers in a default network. In this case, just emit --net flag in docker run command

Step 1: start mongodb and mongo-express

docker-compose -f docker-compose.yaml up

You can access the mongo-express under localhost:8080 from your browser

Step 2: Open mongo-express from browser

http:https://localhost:8081

Step 3: Create eric-db db and eric-collection collection and document with {some_id: 1, data: "some dynamic data loaded from db"} in mongo-express
