About

Idem plugin with built-in functions

What is POP?

This project is built with pop, a Python-based implementation of Plugin Oriented Programming (POP). POP seeks to bring together concepts and wisdom from the history of computing in new ways to solve modern computing problems.

Getting Started

Prerequisites

• Python 3.7+

• git (if installing from source, or contributing to the project)

Installation

Note

If wanting to contribute to the project, and setup your local development environment, see the CONTRIBUTING.rst document in the source repository for this project.

If wanting to use idem-core-functions, you can do so from source.

Install from source

# clone repo
git clone git@<your-project-path>/idem-core-functions.git
cd idem-core-functions

# Setup venv
python3 -m venv .venv
source .venv/bin/activate
pip install -e .

Usage

This Idem plugin functions can be executed with exec.run state that can then be used with other idem plugin like idem-aws, idem-k8s etc as arg-binding.

Setup

After installation, the idem-core-functions execution modules will be accessible to the pop hub.

You are ready to use idem-core-functions!!!

Exec Module

Exec modules can be run from SLS using the “exec.run” state. The return from the exec module is put in the state’s “new_state”, so it can be used in arg_binding. The desired state of a resource can be specified in sls file. The “core.encoding.base64encode” to apply Base64 encoding to a string. The “core.encoding.base64decode” takes a string containing a Base64 character sequence and returns the original string. The “core.conversion.to_json” to serialize an object to a string of JSON The “core.collection.distinct” to return a new list with any duplicate elements removed for a given list. The “core.collection.flatten” to eplaces any elements that are lists with a flattened sequence of the list for a given list. The “core.collection.element” to retrieve a single element from a list. The “core.collection.length” to determine the length of a given list, map, or string.
