How to disable management endpoint probing with Spring Boot Admin?

Question

We are running Spring Boot Admin in our k8s cluster. Applications with SBA client library are discovered during startup and SBA(server) is calling management endpoint during specified interval. We are actually interested to only probe i.e /health and /info endpoint without /actuator. Currently SBA is calling also management endpoint /actuator.

How to configure it to run server without calling management endpoint?

We would like to disable management endpoint for security purpose.

SBA Admin & SB version 2.6.6

I tried tweaking the settings but none of them solved my issue.

/actuator is the "meta" endpoint providing information about the available actuator endpoints. But you cannot "manage" anything there. The docs call it the "discovery page".

If you activate health and info, then /actuator will tell that these are enabled and output should be something like

GET http://127.0.0.1:8100/actuator

{
  "_links": {
    "self": {
      "href": "http://127.0.0.1:8100/actuator",
      "templated": false
    },
    "health": {
      "href": "http://127.0.0.1:8100/actuator/health",
      "templated": false
    },
    "health-path": {
      "href": "http://127.0.0.1:8100/actuator/health/{*path}",
      "templated": true
    },
    "info": {
      "href": "http://127.0.0.1:8100/actuator/info",
      "templated": false
    }
  }
}

The SBA server uses this endpoint to know which actuators are available.

However, you can disable the endpoint in the monitored apps and everything should still work fine:

management.endpoints.web.discovery.enabled=false
