New start-point Architecture

There's been a major change to the cyber-dojo start-points architecture.
Start-points are now docker images rather than docker volumes.

Do an update

On your server, do an update:

$ ./cyber-dojo update

Bring up a server with named start-point images

When you bring up a cyber-dojo server, you can name start-point docker images.
For example, in this command:

$ ./cyber-dojo up \ --custom=acme/my-custom \ --exercises=acme/my-exercises \ --languages=acme/my-languages

the three start-point images are named acme/my-custom, acme/my-exercises, and acme/my-languages.
You can omit any of these three -- options and it will use a default.
The default --custom image name is cyberdojo/custom
The default --exercises image name is cyberdojo/exercises
The default --languages image name is cyberdojo/languages-common which holds start-points for the more common language+testFrameworks (C#, C++, Java, Javascript, Python).
These three default start-point images were created using, respectively:

$ ./cyber-dojo start-point create \ cyberdojo/custom \ --custom \ https://github.com/cyber-dojo/custom.git $ ./cyber-dojo start-point create \ cyberdojo/exercises \ --exercises \ https://github.com/cyber-dojo/exercises.git $ ./cyber-dojo start-point create \ cyberdojo/languages-common \ --languages \ $(curl --silent https://raw.githubusercontent.com/cyber-dojo/languages/master/url_list/common)

The image cyberdojo/languages-all holds start-points for all the language+testFrameworks. It was created using:

$ ./cyber-dojo start-point create \ cyberdojo/languages-all \ --languages \ $(curl --silent https://raw.githubusercontent.com/cyber-dojo/languages/master/url_list/all)

To see more help on the up command:

$ ./cyber-dojo up --help

Create your own start-point images

The --dir option was one way, in the old architecture, to create your own start-point volume. For example:

$ ./cyber-dojo start-point create \ tutorials \ --dir=/Users/fred/custom-tutorials

The --dir option is no longer supported. You must now explicitly name the start-point type (--custom, --exercises, --languages) and provide a list of git-repo URLs. For example, the command:

$ ./cyber-dojo start-point create \ tutorials \ --custom \ /Users/fred/custom-tutorials

now creates a --custom start-point image named tutorials and each URL must be git cloneable and contain at least one manifest.json file adhering to the start-point json format.

The --git option was another way, in the old architecure, to create your own start-point volume. For example:

$ ./cyber-dojo start-point create \ tdd \ --git=https://github.com/org/repo/exercises-tdd.git

The --git option is no longer supported. You must now explicitly name the start-point type (--custom, --exercises, --languages) and provide a list of git-repo URLs. For example, the command:

$ ./cyber-dojo start-point create \ tdd \ --exercises \ https://github.com/org/repo/exercises-tdd.git

now creates an --exercises start-point image named tdd and each URL must be git cloneable and contain at least one manifest.json file adhering to the start-point json format.

The --list option was the last way, in the old architecture, to create your own start-point volume. For example:

$ ./cyber-dojo start-point create \ ruby \ --list=https://raw.githubusercontent.com/org/repo/master/langs-ruby-urls

The --list option is no longer supported. You must now explicitly name the start-point type (--custom, --exercises, --languages) and provide a list of git-repo URLs. For example, the command:

$ ./cyber-dojo start-point create \ ruby \ --languages \ $(curl --silent https://raw.githubusercontent.com/org/repo/master/langs-ruby-urls)

now creates a --languages start-point image named ruby and the curl command must expand to a list of URLs each of which is git cloneable and contains at least one manifest.json file adhering to the start-point json format.

To see more help on the start-point create command:

$ ./cyber-dojo start-point create --help

Create a manifest.json file for each exercise

In the old architecture, each --exercises start-point entry was simply a file called instructions. The name associated with each instructions file (when you set up a practice session) was the name of the directory where it lived (with underscores replaced by spaces). In the new architecture, each --exercises start-point URL must be git cloneable and contain at least one manifest.json file adhering to a subset of the start-point json format:

• You must specify only the display_name and visible_filenames entries.
• visible_filenames cannot contain a file called cyber-dojo.sh

For example:

{ "display_name": "Fizz Buzz", "visible_filenames": [ "instructions" ] }

Inspect a start-point image

To show (in JSON format) each display_name (eg "C (gcc), assert"), git-repo URL+SHA and image_name.
For example:

$ docker pull cyberdojo/languages-common $ ./cyber-dojo start-point inspect cyberdojo/languages-common { ... "C#, NUnit": { "url": "https://github.com/cyber-dojo-languages/csharp-nunit", "sha": "97eb6f778b777ee7bc789a44417c3440cbe2439a", "image_name": "cyberdojofoundation/csharp_nunit" }, ... "C (gcc), assert": { "url": "https://github.com/cyber-dojo-languages/gcc-assert", "sha": "1a9724fde31295a08054d93695180d64fcf05ccd", "image_name": "cyberdojofoundation/gcc_assert" }, ... "Python, unittest": { "url": "https://github.com/cyber-dojo-languages/python-unittest", "sha": "843ebcf9e308ffb9bf686ef5e27e577f9395798b", "image_name": "cyberdojofoundation/python_unittest" }, ... }

List all start-point images

In JSON format, by type:

$ ./cyber-dojo start-point ls { "custom": [ "cyberdojo/custom:latest" ], "exercises": [ "cyberdojo/exercises:latest" ], "languages": [ "cyberdojo/languages-all:latest", "cyberdojo/languages-common:latest", "cyberdojo/languages-small:latest" ] }
