What is docker-nuke?

docker-nuke is a cleanup tool that wipes out every Docker container, image, and volume on your machine in one shot. Think of it as a "reset button" for your local Docker environment, it clears out everything so you can start fresh without old stuff lingering around. If you're not familiar with Docker, it's a tool developers use to package and run software in isolated environments called containers. Over time, as you build and test things, you accumulate a lot of leftover containers, images (the templates containers are built from), and volumes (storage areas). These leftovers can sometimes cause confusion or conflicts when you're trying to build something new, and they also take up disk space. This script just wipes all of that out at once. The people who would use this are developers who work with Docker regularly and want a quick way to reset their environment. For example, if you're building a new containerized app and something isn't working right, you might want to rule out interference from previous builds. Running this script ensures you're starting with a clean slate, no old containers running in the background, no cached images that might be causing issues. The tradeoff is obvious but worth stating: this script is destructive. It removes everything, not just the stuff related to your current project. There's no selective cleanup or confirmation prompts mentioned in the README, you run it, and everything Docker-related on that machine is gone. So you'd only use it when you're sure you don't need any of your existing Docker data, or when you're working on a machine dedicated to a specific task where a full reset is acceptable. The README doesn't go into much detail beyond the basic usage instructions, so there may not be additional safety features or options. It's a straightforward, single-purpose script.
