CI/CD Engines for Embedded (GitHub Actions / GitLab CI / Jenkins)

Overview

General-purpose CI/CD platforms adapted to embedded workflows: containerized cross-compilation, hardware-in-the-loop test runners, artifact signing, OTA pipelines, and SBOM emission. GitHub Actions dominates new projects, GitLab CI for self-hosted, Jenkins for legacy and complex on-prem hardware.

Benefits

• Near-universal industry knowledge means hiring and onboarding are easy
• Container-based cross-compilation gives reproducible builds
• Self-hosted runners handle HIL test stages and licensed tooling cleanly
• Marketplace ecosystems (Actions, GitLab) accelerate setup

Limitations & Risks

• HIL test farms add operational overhead cloud-native tools don't anticipate
• Cost scales steeply with self-hosted runners and large build matrices
• Secrets, signing keys, and HSM integration need careful design

Recommended Actions

Standardize on one platform per program (GitHub Actions for cloud-friendly, GitLab CI for sovereign/self-hosted), containerize the cross-compile toolchain, and build a self-hosted runner pool for HIL stages. Buildkite is a credible alternative for self-hosted agents with cloud control-plane.

Additional Notes

Pairs with #3 Continuous Integration for Embedded practice (the why). This entry is the engine choice.
