How can i change /proc/sys/kernel/core_pattern file inside the docker container with out privileged mode? Are there any flags to be passed to docker daemon or docker run or anything related to Dockerfile?

The kernel does not support per-container patterns. There is a patch for this, but it is unlikely to go in any time soon. The basic problem is that core patterns support piping to a dedicated process which is spawned for this purpose. But the code spawning it does not know how to handle containers just yet. For some reason a simplified pattern handling which requires a target file was not deemed acceptable.
