running your own cyber-dojo Docker server on Linux

install docker

If docker is not already installed, install it.

• To install manually, follow the instructions on the docker website.
• To install with a script (via curl):
  
  $ curl -sSL https://get.docker.com/ | sh
• To install with a script (via wget):
  
  $ wget -qO- https://get.docker.com/ | sh

---

add your user to the docker group

Eg, something like

$ sudo usermod -aG docker $USER

---

log out and log in again

You need to do this for the previous usermod to take effect.

---

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 a terminal, type:

$ sudo mkdir /cyber-dojo $ sudo chown 19663:65533 /cyber-dojo

---

install the cyber-dojo shell script

In a terminal, type:

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

Now use this cyber-dojo script to run your own cyber-dojo server.
