Checking the health of Java microservices by using Kubernetes readiness and liveness probes
|
Learn how to check the health of microservices on Kubernetes using readiness and liveness probes. Configure Kubernetes to keep your microservices running smoothly with MicroProfile Health.
At a Glance
Learn how to check the health of microservices on Kubernetes by setting up readiness and liveness probes to inspect MicroProfile Health Check endpoints.
You will learn how to create health check endpoints for your microservices. Then, you will configure Kubernetes to use these endpoints to keep your microservices running smoothly.
Kubernetes provides liveness and readiness probes that are used to check the health of your containers. These probes can check certain files in your containers, check a TCP socket, or make HTTP requests. MicroProfile Health exposes readiness and liveness endpoints on your microservices. Kubernetes polls these endpoints as specified by the probes to react appropriately to any change in the microservice’s status. Read the Adding health reports to microservices guide to learn more about MicroProfile Health.
