Buildkite
Buildkite — hybrid CI/CD with fast builds on your own infrastructure.
Stack Components
Why
Runs agents on your hardware for speed, scales horizontally, great DX. Docker is used by 59% of professional developers per the Stack Overflow 2024 survey, and Terraform is used by 65% of organizations for IaC (HashiCorp 2024).
GitOps (ArgoCD, Flux) reduces deployment drift to near-zero by making git the single source of truth.
When
Use for teams needing fast builds on own hardware. Avoid for fully managed CI.
How
Example
Common Problems
- ⚠Agent not connecting — check BUILDKITE_AGENT_TOKEN
- ⚠Queue starvation — add more agents to queue
- ⚠Configuration drift between environments — use infrastructure-as-code (Terraform/Pulumi) to keep dev/staging/prod identical
Best Practices
- ✓Use parallel steps for independent jobs
- ✓Cache dependencies with cache plugin
- ✓Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit
FAQ
What is Buildkite and what projects is it for?
Buildkite — hybrid CI/CD with fast builds on your own infrastructure. It pairs layered technologies for end-to-end type safety and out-of-the-box deploys, fitting everything from MVPs to production SaaS.
How do I spin up a working demo with Buildkite in 10 minutes?
Two steps: (1) Sign up at buildkite.com; (2) Install agent on your machine. Get the local dev server running, then wire one real data source to verify the end-to-end loop.
What is the most common pitfall with Buildkite and how do I avoid it?
The most common pitfall is: Agent not connecting — check BUILDKITE_AGENT_TOKEN. Avoid it by adding the matching checklist to your PR template and running type-check + lint + unit tests in CI — three gates before merge.
What are the best practices for Buildkite?
Best practices for Buildkite include: Use parallel steps for independent jobs; Cache dependencies with cache plugin; Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit. The first one — "Use parallel steps for independent jobs" — should be set up at project init to avoid costly rework later.
When should I NOT choose Buildkite?
Pick something else in three cases: (1) the team has zero experience with the core framework and the deadline is tight (learning-curve risk); (2) it's a pure content/marketing site (Astro is lighter); (3) you need very high throughput (>10k RPS) or strict-consistency microservices (Go/Rust). Buildkite shines for mid-to-high complexity full-stack and API work — don't over-engineer simple static pages with it.
