Unfortunately, an external system that is shared by all application instances is common, and you have to make a judgement call: Include it in the readiness probe and expect that the application is taken out of service when the external service is down or leave it out and deal with failures higher up the stack, perhaps by using a circuit breaker in the caller. Other external systems might not be essential to the application (the application could have circuit breakers and fallbacks), in which case they definitely should not be included. Some external systems might not be shared by application instances, in which case they could be included in a readiness probe. If the readiness state of an application instance is unready, Kubernetes does not route traffic to that instance. With the key listed in the following table: KeyĬhecks that a connection to DataSource can be obtained.Ĭhecks that an Elasticsearch cluster is up.Īs for the “readiness” probe, the choice of checking external systems must be made carefully by the application developers.įor this reason, Spring Boot does not include any additional health checks in the readiness probe. You can also enable or disable selected indicators by configuring , When appropriate, Spring Boot auto-configures the HealthIndicators listed in the following table. Requires the SpringApplication to be configured with a BufferingApplicationStartup. Shows the startup steps data collected by the ApplicationStartup. Lets the application be gracefully shutdown.

Shows information about Quartz Scheduler jobs.ĭisplays the scheduled tasks in your application.Īllows retrieval and deletion of user sessions from a Spring Session-backed session store. Shows “metrics” information for the current application. Shows any Liquibase database migrations that have been applied. Shows and modifies the configuration of loggers in the application. Requires a dependency on spring-integration-core. Shows any Flyway database migrations that have been applied.ĭisplays HTTP exchange information (by default, the last 100 HTTP request-response exchanges). Shows the conditions that were evaluated on configuration and auto-configuration classes and the reasons why they did or did not match.ĭisplays a collated list of all properties from Spring’s ConfigurableEnvironment.
