CI/CD Pipeline Documentation

This documentation provides a comprehensive overview of our GitHub Actions CI/CD pipeline, explaining how the different workflows interact and work together to build, test, and release our software.

Overview

Our CI/CD pipeline is designed to automate the process of building, testing, and releasing our software across multiple platforms and architectures. The pipeline consists of four main workflows:

1. Binary Builder: Builds binary executables for multiple platforms (Linux, macOS, Windows) and architectures (x64, arm64)
2. Binary Testing: Tests the built binaries to ensure they function correctly on each platform
3. Release Creator: Creates GitHub releases with the built and tested binaries
4. Workflow Validation: Ensures that all workflows follow our security and best practices guidelines

These workflows work together to provide a seamless and automated process from code commit to software release.

Workflow Relationships

The following diagram illustrates how our workflows interact with each other:

Loading

Workflow Triggers

• Binary Builder: Triggered on push to main/development branches or manually
• Binary Testing: Triggered after successful completion of Binary Builder
• Release Creator: Triggered after successful completion of Binary Builder on the main branch
• Workflow Validation: Triggered on pull requests that modify workflow files or manually

Artifact Flow

1. Binary Builder produces binary artifacts for each platform/architecture
2. Binary Testing consumes these artifacts to perform tests
3. Release Creator also consumes these artifacts to create GitHub releases

Key Components

Our CI/CD pipeline includes several key components:

1. Matrix Builds

We use matrix builds in the Binary Builder workflow to build binaries for multiple platforms and architectures in parallel:

• Linux (x64, arm64)
• macOS (x64, arm64)
• Windows (x64)

2. Artifact Management

Artifacts are passed between workflows using GitHub Actions artifacts:

• Binary artifacts are uploaded by the Binary Builder workflow
• These artifacts are downloaded by the Binary Testing and Release Creator workflows

3. Release Management

The Release Creator workflow:

• Creates GitHub releases with appropriate version tags
• Attaches binary artifacts to the release
• Generates release notes

4. Quality Assurance

Quality is ensured through:

• Binary testing across all supported platforms
• Workflow validation to enforce security best practices
• Automated issue creation for test failures

Workflow Documentation

Detailed documentation for each workflow:

• Binary Builder: Building cross-platform binaries
• Binary Testing: Testing binary functionality
• Release Creator: Creating GitHub releases
• Workflow Validation: Ensuring workflow quality and security

Glossary of CI/CD Terms

Term	Definition
Artifact	A file or collection of files produced during the build process that is stored for later use, such as compiled binaries or test reports.
CI (Continuous Integration)	The practice of frequently merging code changes into a shared repository, with automated builds and tests to detect problems early.
CD (Continuous Delivery/Deployment)	The practice of automatically deploying all code changes to a testing or production environment after the build stage.
GitHub Actions	GitHub's built-in CI/CD platform that allows automation of software workflows directly in a GitHub repository.
Workflow	A configurable automated process made up of one or more jobs, defined in YAML files in the .github/workflows directory.
Job	A set of steps in a workflow that execute on the same runner (virtual machine).
Step	An individual task that can run commands or actions within a job.
Runner	A server that runs GitHub Actions workflows, either GitHub-hosted or self-hosted.
Action	A reusable unit of code that can be used in workflows, either from the GitHub Marketplace or custom-built.
Matrix Build	A strategy that allows running multiple jobs with different configurations in parallel.
Environment Variables	Variables that are set in the workflow environment and can be used by steps in the workflow.
Secrets	Encrypted environment variables that are only exposed to selected actions.
Trigger	An event that causes a workflow to run, such as a push, pull request, or manual dispatch.
Concurrency	A feature that ensures only one workflow run with the same concurrency group runs at a time.
Permissions	Controls what actions a workflow can perform, following the principle of least privilege.
Pinned Action	An action that is referenced by its specific commit SHA rather than a tag, for security purposes.
Timeout	A limit on how long a job or workflow can run before it is automatically cancelled.
Artifact Retention	The period of time that artifacts are stored before being automatically deleted.
Self-hosted Runner	A runner that you host yourself, as opposed to the GitHub-hosted runners.
Workflow Dispatch	A manual trigger for a workflow.
