What is BuildCharts?

buildcharts is a framework for defining and generating CI/CD pipelines using declarative metadata (build.yaml) and templated pipeline definitions stored as OCI artifacts (similar to Helm charts). It enables scalable, centralized, and consistent build processes.

Features

• Scaling: Handle 150+ similar apps with shared pipeline logic.
• Control: Centralize logic like adding Datadog agents or custom validation to all builds.
• Extensibility: You can write dependency resolution plugins to block known-bad versions.

Core Concepts

• build.yaml: Project-specific metadata.
• build.lock.yaml: Lock file that pins exact templates/versions used (like package-lock.json or Chart.lock).
• Chart Templates: Stored as OCI images with Helm-like templates (but for CI/CD instead of K8s). You use a custom renderer (buildcharts) instead of real Helm.
• Dynamic Pipeline Generation: Pipelines (e.g., GitHub Actions or Azure DevOps) are generated dynamically based on the metadata file and templates.
• Artifact Output Support: Supports Docker images, NuGet packages, test results, etc.

Templates support:

• 🐳 Docker image builds
• 🧪 Test runners
• 📦 NuGet packaging
• 📂 Artifact collection
• 🧰 Custom plugins (versioning, summaries, contributors, etc.)

🔄 Dependency Updates & Channels

• Integrated with Renovate (or Maestro) to update build.yaml/Chart.lock via PRs when templates/dependencies change.
• Uses OCI tags and optional channel: fields to control release flows (e.g., dev/staging/prod templates or NuGet channels).
• Renovate can track changes like it does with Helm or NuGet and trigger the pipeline generator accordingly.

CLI

Supports dynamic generation at runtime (e.g., pipeline generates new pipelines via API or buildx bake).

buildcharts
  init         # scaffold
  update       # resolve templates + create lock
  generate     # render CI/CD pipelines
  run          # trigger or test the pipelines
  diff         # show changes vs lock
  validate     # schema and template check
  clean        # remove generated artifacts
  version      # version info
  package      # package chart
  pull         # pull chart
    - helm pull oci://docker.io/buildcharts/dotnet-build --version 0.0.1
