About

Katharsis is a simple GUI for the Kathara computer network emulation framework. It allows you to start and stop labs and connect to the containers in a convenient way. It allows you to conveniently open multiple container terminals next to each other. Katharsis requires Docker to be installed in rootful mode, and you have to be in the docker group.
