running your own cyber-dojo Docker server on a Mac

These instructions are intended for individuals wishing to run cyber-dojo locally on their Mac laptop.
Note that these instructions are for running Docker-Toolbox for Mac.
Running Docker Desktop for Mac may or may not work.

install Docker-Toolbox for Mac

From here.

---

open a Docker-Quickstart-Terminal

---

get your cyber-dojo server's IP address

In the Docker-Quickstart-Terminal, type:

$ docker-machine ip default

It will print something like 192.168.99.100

---

ssh into your cyber-dojo server

In the Docker-Quickstart-Terminal, type:

$ docker-machine ssh default

---

setup directory permissions

cyber-dojo saves the practice sessions to /cyber-dojo
You need to set the correct permissions for this directory.
The user-id for the saver service is 19663, and its group-id is 65533.
In the cyber-dojo server terminal, type:

docker@default:~$ sudo mkdir /cyber-dojo docker@default:~$ sudo chown 19663:65533 /cyber-dojo

---

install the cyber-dojo script

In the cyber-dojo server terminal, type:

docker@default:~$ curl -O https://raw.githubusercontent.com/cyber-dojo/commander/master/cyber-dojo docker@default:~$ chmod 700 cyber-dojo

Now use this cyber-dojo script, from a (default VM) cyber-dojo server terminal, to run your own cyber-dojo server.
