igor

Opens a shell in your favorite docker container mounting your current workspace into the container.

Install

Just download the igor.sh and store it in your $PATH like this:

sudo curl https://raw.githubusercontent.com/felixb/igor/master/igor.sh -o /usr/local/bin/igor
sudo chmod +x /usr/local/bin/igor

Usage

Without any config, igor launches a shell inside a busybox container:
