My cluster have many java applications running on it, I would like to take thread dump for few microservices. But as these are distroless images, I was thinking of ephemeral containers but not sure if volume can be attached to such containers. Can someone help?

Regards, Anjani

Are you using Spring Boot to build those microservices? If yes, then by using Spring Boot Admin you can get thread dumps, heap dumps and monitor your services from a single window.

Please check here to get more details about it.

Check Spring Boot actuator endpoints https://docs.spring.io/spring-boot/docs/current/reference/html/actuator.html#actuator.endpoints

There is a dedicated endpoint for thread dumps. Note that by default it returns custom JSON format, but you could request default text format.

curl 'http://localhost:8080/actuator/threaddump' -i -X GET \
-H 'Accept: text/plain'

See for more details https://docs.spring.io/spring-boot/docs/current/actuator-api/htmlsingle/#threaddump.retrieving-text
