Description:

rkdcooperative 1.0.3

Sharing snippets, plugins, packages never was so easy. rkd-coop is a GIT-based tool similar to package manager that have repositories on GIT/Github!
Uses popular and easy JINJA2 templating to render configuration files based on answers asked to the user during snippet installation.
Perfect tool to:

Share ready-to-use, customizable configuration files
Share docker-compose.yml definitions where you can parametrize database credentials, container names
Install plugins to any application (example flow: ask which version, download, unpack)

pip install rkd-snippet-cooperative

export COOP_REPOSITORIES=https://github.com/riotkit-org/riotkit-harbor-snippet-cooperative
rkd-coop :cooperative:sync # similar to apt update, huh?
rkd-coop :cooperative:install harbor/redis

Installing
# with pipenv
pipenv install rkd-cooperative

# using regular PIP
pip install rkd-cooperative

How it works?
The mechanism is using GIT repository as a central repository of content, there is a command to synchronize all repositories rkd-coop :cooperative:sync.
With rkd-coop :cooperative:install NAME a snippet can be installed from local repository.

Repository and snippets structure
Example structure
README.md

# main directory with snippets, can contain directories with snippets directly or additionally the categories
snippets/
snippets/web-servers/

# snippet main directory, maintained by a maintainers listed in a separate file
snippets/web-servers/nginx
snippets/web-servers/nginx/snippet.json # this file is mandatory for RKD-COOP to find the snippet at all

# RKD's makefile defines how to install the snippet (eg. interactive installation wizards)
snippets/web-servers/nginx/.rkd/makefile.yaml

# files to copy to "./" (current workspace), all *.j2 files are rendered and .j2 extensions are cut off
# can include subdirectories of any depth
snippets/web-servers/nginx/files/nginx.conf.j2
Example snippet.json file
{
"description": "Simplest Redis Server configuration with persistent volume",
"maintainers": ["Andrew Johnson <https://github.com/blackandred>"],
"version": "1.0"
}

Makefile - creating interactive wizards
In RKD’s Makefile you can define tasks. The RKD-COOP is expecting that you could define task :snippet:wizard,
in which you can use a Wizard to ask user questions. Of course RKD’s tasks are executed in a programming language, so you can
actually do everything you want there using Bash and Python.
Below is an example .rkd/makefile.yaml file with customized “wizard” that asks user for a domain name, and for the basic auth password.
Please notice the to_env=True - it means, that user input would be written to .env file as AUTH_PASSWORD variable.
Every attribute is exposed into *.j2 templates when those are rendered, giving a possibility to render customized files basing on user input.
version: org.riotkit.rkd/yaml/v1
tasks:
:snippet:wizard:
arguments:
"path":
help: "Path to the snippet"
steps: |
#!python
from rkd.inputoutput import Wizard

Wizard(this)\
.ask('Domain name', attribute='domain_name', regexp='([A-Za-z0-9_]+)', default='localhost')\
.ask('Basic auth password', attribute='AUTH_PASSWORD', to_env=True)\
.finish()

Makefile - advanced usage: Overriding files copying procedure
Beside the :snippet:wizard task RKD-COOP allows to customize the process of installing the snippet. The default behavior
is to copy all files from “files” directory recursively, and render *.j2 templates on-the-fly. That’s a pretty universal behavior.
:snippet:install can be implemented to override default behavior with eg. file downloading and unpacking, git cloning or other desired behavior.
version: org.riotkit.rkd/yaml/v1
tasks:
#
# Here could be defined also other tasks, including :snippet:wizard
# You can call other tasks in Bash with: %RKD% :my-task-name
# In Python: this.rkd([':my-task-name', '--some-argument=some-value'])
#

:snippet:install:
arguments:
"path":
help: "Path to the snippet"
steps: |
#!bash
wget https://github.com/riotkit-org/tunman/archive/master.zip
unzip master.zip
rm master.zip
# ...

Join it into your project or custom RKD distribution
RKD-COOP is a set of RKD tasks you can import into any project. Additionally you can define COOP_REPOSITORIES environment variable by default
so your project would use fixed repositories by default when calling sync task.
Simply set COOP_REPOSITORIES in makefile.yaml, makefile.py or in .env file.
For makefile.py (RKD Makefile.py syntax)
from rkd_cooperative import imports as CoopImports

IMPORTS += CoopImports()
For makefile.yaml (RKD Makefile YAML syntax)
imports:
- rkd_cooperative

Simplicity over complexity
Snippet cooperative is not an application store, or a package manager.
It is intended to be a simple snippet store, but we do not exclude implementation of “store-like” mechanism in the future if there will be a lot of requests for such feature.
