mach-composer 1.2.4

Documentation: docs.machcomposer.io

MACH composer is a framework that you use to orchestrate and extend modern digital commerce & experience platforms, based on MACH technologies and cloud native services. It provides a standards-based, future-proof tool-set and methodology to hand to your teams when building these types of platforms.

It includes:

• A configuration framework for managing MACH-services configuration, using infrastructure-as-code underneath (powered by Terraform)
• A microservices architecture based on modern serverless technology (AWS Lambda and Azure Functions), including (alpha) support for building your microservices with the Serverless Framework
• Multi-tenancy support for managing many instances of your platform, that share the same library of micro services
• CI/CD tools for automating the delivery of your MACH ecosystem
• Tight integration with AWS an Azure, including an (opinionated) setup of these cloud environments

The framework is intended as the 'center piece' of your MACH architecture and incorporates industry best practises such as the 12 Factor Methodology, Infrastrucure-as-code, DevOps, immutable deployments, FAAS, etc.

With combining (and requiring) these practises, using the framework has significant impact on your engineering methodology and organisation. On the other hand, by combining those practises we believe it offers an accelerated 'way in' in terms of embracing modern engineering practises in your organisation.

Installation

• Make sure you have Terraform 0.14 installed (tip: Use tfenv to support multiple versions of Terraform)
• Create a new virtualenv with Python 3.8
• Run the following commands:

$ make install

Running MACH

To generate the files:

mach generate # generates all available configs.

mach generate -f main.yml

To init Terraform (optional):

mach init

To plan Terraform:

mach plan

To apply Terraform config:

mach apply

Checking for updates

MACH can check your components for available updates.

To do this, run:

mach update -f main.yml

Code style

The Python source code should be formatted using black and the JavaScript code should be formatted using prettier. You can use make format to run both black and prettier.

This project uses pre-commit to validate the changed files before they are committed. You can install it on MacOS using brew:

$ brew install pre-commit

In the repository you need to register the hooks in git the first time using:

$ pre-commit install

The pre-commit config (.pre-commit-config.yaml) currently runs black and flake8.
