第8章 Using greenboot for application and workload health checks

Greenboot health checks are helpful on edge devices where direct serviceability is either limited or non-existent. You can use greenboot health checks to assess the health of your workloads and applications. These additional health checks are useful for software problem detection and automatic system rollbacks.

Workload or application health checks can use the MicroShift basic health check functions already implemented for the MicroShift core services. Creating your own comprehensive scripts for your applications is recommended. For example, you can write one that verifies that a service has started.

You can also use the microshift healthcheck command, which can run checks that the basic functions of the workload are operating as expected.
