Chapter 5. Performing health checks on Red Hat Quay deployments
Health check mechanisms are designed to assess the health and functionality of a system, service, or component. Health checks help ensure that everything is working correctly, and can be used to identify potential issues before they become critical problems. By monitoring the health of a system, Red Hat Quay administrators can address abnormalities or potential failures for things like geo-replication deployments, Operator deployments, standalone Red Hat Quay deployments, object storage issues, and so on. Performing health checks can also help reduce the likelihood of encountering troubleshooting scenarios.
Health check mechanisms can play a role in diagnosing issues by providing valuable information about the system’s current state. By comparing health check results with expected benchmarks or predefined thresholds, deviations or anomalies can be identified quicker.

-
On your web browser, navigate to
https://{quay-ip-endpoint}/health/instance. You are taken to the health instance page, which returns information like the following:
{"data":{"services":{"auth":true,"database":true,"disk_space":true,"registry_gunicorn":true,"service_key":true,"web_gunicorn":true}},"status_code":200}For Red Hat Quay,
"status_code": 200means that the instance is health. Conversely, if you receive"status_code": 503, there is an issue with your deployment.
