Run a one off container

Build and run a container in one command, automatically cleaning up when done:

docker run --rm -it $(docker build -q .)

Breakdown

• docker build -q . - Builds image from current directory (quiet mode, returns only image ID)
• $(...) - Command substitution to capture the image ID
• --rm - Automatically remove container when it exits
• -it - Interactive mode with TTY allocation

Use cases

• Quick testing of a Dockerfile
• Running build scripts in a clean environment
• One-time data processing tasks

Alternative: If you need to pass arguments or mount volumes:

docker run --rm -it -v $(pwd):/app $(docker build -q .) /bin/bash
