3 Musketeers

What

The 3 Musketeers is a pattern for developing software in a repeatable and consistent manner. It leverages Make as an orchestration tool to test, build, run, and deploy applications using Docker and Docker Compose. The Make and Docker/Compose commands for each application are maintained as part of the application’s source code and are invoked in the same way whether run locally or on a CI/CD server.

Why

Consistency

Run the same commands no matter where you are: Linux, MacOS, Windows, CI/CD tools that supports Docker like GitHub Actions, Travis CI, CircleCI, and GitLab CI.

Control

Take control of languages, versions, and tools you need, and version source control your pipelines with your preferred VCS like GitHub and GitLab

Confidence

Test your code and pipelines locally before your CI/CD tool runs it. Feel confident that if it works locally, it will work in your CI/CD server.

Demo

The demo was generated with VHS using the 3 Musketeers (source).
