Oracle RAC in Docker fails on Ubuntu Server 20.04.4 LTS with Error response from daemon: Your kernel does not support CPU real-time scheduler

Apparently, it needs a real time kernel, which involves recompiling and installing a custom kernel. However, Ubuntu claims their low latency kernel is good enough:

Possibly they will have a RT kernel soon. But, the question is. is the low latency kernel good enough? I'm am not asking for production purposes.

@Altitude-Dashboard , RAC requires RT processes as of today so better to have it. RAC on Docker is supported on OL7.x. For details, please refer following:

Can we close this issue, we know it works on OL7 which is supported. Ubuntu is not supported at the moment.
