+## MERN-Docker - Starter for building MERN Apps using Docker
+
+![MERN DOCKER diagram](https://github.com/sujaykundu777/mern-docker/blob/master/3-tier-diagram.png?raw=true)
+### Prerequisites:
+
+You must have Docker Installed in your System !
+
+### How to run the App :
+
+Article - ![Tutorial](https://dev.to/sujaykundu777/utilizing-the-power-of-docker-while-building-mern-apps-using-mern-docker-4olb)
+
+##### In Development Mode :
+
+First copy the content of **docker-compose-dev.yml** to **docker-compose.yml**
+
+and also copy the content of **server/src/index.dev.js** to **server/src/index.js**
+
+Run the app using :
+
+`$ docker-compose up --build --remove-orphans`
+
+or
+
+`$ docker-compose up -d`
+
+Above command will start the services on (-d) detach mode (similar like running the app in background)
+
+Then you can check the status of the containers by running:
+
+`$ docker ps`
+
+The App should be App :
+
+visit client : http://localhost:3000
+
+visit server : http://localhost:8080
+
+To check the status of the running containers :
+
+`docker-compose ps`
+
+##### In Production Mode :
+
+First copy the content of **docker-compose-prod.yml** to **docker-compose.yml**
+
+and also copy the content of **server/src/index.prod.js** to **server/src/index.js**
+
+Run the app using :
+
+` $ docker-compose up --build -remove-orphans`
+
+The App should be up at http://localhost:8080
+
+### Build the image for server :
+docker build -t myapp-server:1 .
+docker images
+docker run --name "myapp-server" -p 80:8080 myapp-server:1
+docker ps
