Debugging Docker applications may require thread or heap dumps. By using simple commands within Docker, developers can find process IDs and execute dumps efficiently.
To capture a thread dump, execute 'ps -fea | grep -i java' inside the container to find the PID of the Java process running your application.
After locating the Java process, you can use tools like jstack or jmap to capture the thread dump directly from the running Docker instance.
Once the dump is created, you can easily copy the file from the container to the host machine, enabling detailed analysis.
