# To run mongo db container 

docker run mongo   

# docker run -d --name mongoDB mongo 

docker container inspect mongoDb  

under Networking setting you will find "IPAddress": "172.17.0.2",

replace the connection string in  the appjs file with ip address like below

eg   'mongodb://172.17.0.2:27017/mymongodb',

then build the image again

docker build -t mongodb-app .

docker run -d -p 4000:80 --name mongoDbv1 mongodb-app

# Now we check docker run we see two containers running

docker ps

should see below

PS Z:\nodes\myTutorials\docker\dockerAppMongoDB> docker ps

PS Z:\nodes\myTutorials\docker\dockerAppMongoDB> 

# From the above you will see two containers running

one the mongo image container from docker hub

second is the our app container running on our host machine

# from the above we are running two containers mongo container and app container (mongodb-app)

docker build -t mongodb-app .

docker run -d -p 4000:80 --name mongoDbv1 mongodb-app

// From thses we will now try to multiple containers with each talking to each other via the 

Network. Keep learning :)
