vela-stages

What problem does it solve?

This Skill addresses the need for efficient parallel execution of tasks within CI/CD pipelines, enabling faster build and deployment cycles by running independent jobs concurrently.

Core Features & Use Cases

• Parallel Stage Execution: Run multiple stages of your pipeline simultaneously to reduce overall build time.
• Dependency Management: Define explicit dependencies between stages using the needs key, ensuring correct execution order.
• Stage Isolation: Use the independent key to prevent a stage's failure from halting unrelated parallel stages, crucial for monorepos.
• Compile-Time Pruning: Understand how rulesets can cause entire stages to be removed before execution, and how to manage needs dependencies accordingly.
• Use Case: In a monorepo, you can have separate stages for building and testing the backend and frontend applications, running them in parallel. A subsequent deployment stage would then wait for both to complete successfully.

Quick Start

Use the vela-stages skill to define a pipeline with two parallel stages, 'build' and 'test', where 'deploy' depends on both.
