Jolokia endpoint is not exposed through spring boot actuator in open shift

Question

I have a camel application which is running in spring boot 2 and camel routes are visualized through hawtio. And all actuator endpoints are exposed including jolokia endpoint

this application is completely working in local and when I try to access actuator endpoints in local http://localhost:8080/actuator/, i could see below endpoint along with other 16 endpoints (such as health, info and so on)

"jolokia": {
"href": "http://localhost:8080/actuator/jolokia",
"templated": false
}

I have deployed the in same Openshift, but when i try to access actuator endpoints in Openshift i could see only 16 endpoints without jolokia endpoint

Application start up logs in local

INFO : Registered '/actuator/jolokia' to jolokia-actuator-endpoint is missing in Openshift logs, so clearly its not registered with spring boot actuator

Any idea why jolokia is not exposed via spring boot actuator ?

because of this hawtio is not able to access camel routes (JMX).

Issue is resolved Solution : Disable the default OpenJDK8 jolokia in Openshift

In Local

Application is not running in Openshift / Docker as an image, running as normal spring boot application in tomcat so I didn't face this issue.

In Openshift

Application is running in openshift / Docker as an image instance. The image is created with base openJDK 8 which has default jolokia enabled Red hat openshift reference

I have disabled it by overriding it with AB_JOLOKIA_OFF:true in openshift environment variables.

or either if you are using maven fabric8 plugin in pom for building image then you can override jolokia properties it in pom itself (i haven't try it but its possible as per documents).
