Readiness Probe - CI/CD Glossary Definition
Readiness Probe: A readiness probe checks whether an instance is ready to accept work; if it fails, the instance stays running but receives no new traffic until it passes.
A readiness probe checks whether an instance is ready to accept work; if it fails, the instance stays running but receives no new traffic until it passes.
Readiness answers "can this instance take requests right now?". A pod still warming up caches is alive but not ready, so it should not get traffic yet.
In CI
A containerized runner exposes a readiness endpoint that passes only after its toolchain is installed, so the scheduler does not assign a build before the runner can actually run it.
