A Docker build focused on security testing...
There's quite a few of these around now, this one is mine :)
using this is fairly easy
docker run -i -t --name <container_name> raesene/sectest /bin/bash
will give you an interactive shell with tools installed the <container_name> should be a name for the instance (for example the name of a test you're doing). If you exit the shell you can then restart the conainer with
docker start -a -i <container_name>
