Management endpoints

Management endpoints

Spring boot actuator exposes a number of management endpoints.

The acl-service instance is configured by default to expose the application itself on port 8080 and the management API on port 8081, and are under the same /acl context path as the application’s API.

So, if the application API is located at http://localhost:8080/acl/api, the Spring Boot Actuator API is at http://localhost:8081/acl/actuator.

The management port can be changed with the standard management.server.port configuration property, including the spring-boot style environment variable alternative MANAGEMENT_SERVER_PORT.

Note however, the environment variable is preferred as it’ll be catch up by the health-check configured in the Docker image:

CMD curl -f -s -o /dev/null localhost:$MANAGEMENT_SERVER_PORT/acl/actuator/health || exit 1

The /actuator/health endpoints, including the liveness and readiness probes /actuator/health/liveness and /actuator/health/readiness are accessible without authentication.

All other management endpoints require authentication with a ROLE_ADMIN user, and will result in a basic auth challenge if accessed anonymously.
