Dockerizing React, Express app using MongoDb database.

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 CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 2575365b3107 mongodb-app "docker-entrypoint.s…" About a minute ago Up About a minute 0.0.0.0:3000->4000/tcp mongoDbv1 6903f4a94373 mongo "docker-entrypoint.s…" 25 minutes ago Up 25 minutes 27017/tcp mongoDb 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 request at postman get request http://localhost:4000/favorites post request http://localhost:4000/favorites mock data { "name": "A new Hope", "type": "movie", "url": "http://swapi.dev/api/films/1/" } // From thses we will now try to multiple containers with each talking to each other via the Network. Keep learning :)
