Docker Debug

Debugging slim images and containers with Docker Debug

At the time of this writing, Docker Debug is a new tool and requires a Pro, Team, or Business subscription. It’s a widely accepted good practice to deploy small images containing only app code and dependencies. This means no shell or debugging tools and is a big part of making images and containers small and secure. However, it also makes it difficult to debug them when things go wrong.

This is where Docker Debug comes to the rescue by allowing us to get shell access to images and containers that don’t include a shell and seamlessly injecting powerful debugging tools into them.
