Docker-ExpressJS

Dockerfile to quickly make ExpressJS app with API on port 8080

Install

1. Clone this repo to a folder in your system

• git clone https://github.com/Codypinto23/Docker-ExpressJS.git

To Run Dockerfile

1. First build the docker image (we'll name it 'express-image')

• docker build . -t express-image

2. Now run a container using that image (we'll name it 'express-demo'). We'll map our port 80 to the container's port 8080

• docker run -it --rm -p 80:8080 --name express-demo express-image

Notes:

1. To exit out of the docker and keep it running, type ctrl-p, ctrl-q
2. The -i tag means we run the docker container in interactive mode, which lets us keep it open, even if it's not attached
3. The -t tag means we allocate a psuedo-terminal
