docker-compose up -d --build
    --build: used to save image before running the container
    --detatch: to run in detatch mode

docker build . -t <image_name>

docker run -e CONFIG=<env_name> -p 3000:3000 -d --name <container_name> <image_name>

NOTE: Used to get inside a docker container run shell in container.
docker run -it <image_name> sh
