How to Run a Docker Container From a Dockerfile

Sometimes it's just annoying to build a docker image, then run the container from that image. Even if it's only two 2 commands, it can become very annoying when done repetitively.

Luckily, there is a command to run a container directly from a Dockerfile.

docker run $(docker build -q .)

The -q option suppresses the build output and prints image ID on success.

If you have to expose a port for your container, you can just add the -p flag to your command, and there you go!

docker run -p 8000:8000 $(docker build -q . -t image-name:tag)

                |    'port in your container'
                |
                'port in your computer'
