Introduction
A container that is running does not necessarily mean the application inside it is ready. A workflow platform may start while its database is unreachable; a local model service may respond only after its model has loaded. Health checks should test dependencies that matter to the user, not just the existence of a process.
This article focuses on readiness, not on claiming a measured time saving.
Define readiness for each service
For every container, identify a meaningful readiness condition. That might be an HTTP endpoint returning an expected status, a database accepting a connection, or a model service confirming that the required model is available. A process-level check is useful, but it should not be confused with end-to-end readiness.
Check dependencies and verify the workflow
Document which services depend on others and what the application should do while a dependency is unavailable. Startup order alone does not guarantee that a service is ready when its dependent begins work.…
