setting up your own digital-ocean cyber-dojo server

These instructions are obsolete.

The cyber-dojo server now runs inside a docker-container.
See the new instructions on how to run your own cyber-dojo server.








































Is a simple 6 step process:

1. start from the right image

From http://cloud.digitalocean.com
  • Image: One-click Apps: [Docker 1.9.1 on 14.04]
  • Size: choose $10/month or more


2. install the cyber-dojo github repo

This will take about a minute. As root (making sure you type cyber-hyphen-dojo and not cyberdojo in the git clone command)...
$ cd /var $ mkdir www $ cd www $ git clone https://github.com/JonJagger/cyber-dojo

3. install cyber-dojo as the default rails server and all the necessary gems

This will take 5+ minutes. As root...
$ cd /var/www/cyber-dojo/admin_scripts $ ./setup_digital_ocean_server.sh


4. install pre-built cyber-dojo-foundation docker-images

As root...
$ cd /var/www/cyber-dojo/languages $ ./docker_list_all_images.rb
will tell you the names of the docker-images held in the cyber-dojo-foundation docker hub
For example:
... cyberdojofoundation/clangpp_googletest == C++ (clang++), GoogleTest cyberdojofoundation/coffeescript_jasmine == CoffeeScript, jasmine cyberdojofoundation/csharp_nunit == C#, NUnit cyberdojofoundation/csharp_specflow == C#, SpecFlow cyberdojofoundation/d_unittest == D, unittest cyberdojofoundation/erlang_eunit == Erlang, eunit cyberdojofoundation/fortran_funit == Fortran, FUnit cyberdojofoundation/fsharp_nunit == F#, NUnit cyberdojofoundation/gcc_assert == C (gcc), assert ...


Now do a
$ docker pull <image>
for each image of your choice. For example,
$ docker pull cyberdojofoundation/clangpp_googletest


Alternatively, you can simply pull them all (typically takes 15+ minutes)
$ cd /var/www/cyber-dojo/languages $ ./docker_pull_all_images.rb


Note that whenever you pull new images you will need to repeat step 5.

5. refresh the caches

As root...
$ cd /var/www/cyber-dojo/caches $ ./refresh_all.sh


6. start your server

As root...
$ service apache2 restart

  1. In trying to do step 5, I'm not seeing the refresh script anywhere. Has something changed since these instructions were written?

  3. An update ... I found a refresh_all script in the caches directory, and ran that. It ran the languages script and the exercises script, then I got an error "docker is NOT installed!".
    I can get to my site, but when I click on "Create a practice session" I get an error on the show_languages_and_tests page.

  4. Hmmm. If it's not seeing docker things are definitely not right.
    You might try a [git pull] in the var/www/cyber-dojo directory and then try the script.
    Are you running as root?
    At the terminal what does [docker --version] say?
    Probably won't have any time to look at this till Sunday... Sorry

  5. I've found the problem and fixed it.
    It you go to /var/www/cyber-dojo and do a [git pull] and then repeats steps 5 and 6 you should be ok.
    Thanks for reporting the problem.

  7. Shouldn't the clone url be https://github.com/JonJagger/cyber-dojo.git?
