The following problem sometimes occur:

And also, Bluechi developers suggest that it would probably be best to use some port >1024, e.g. 8420, because 842 is a privileged port. To change the port, it needs to be changed in the ffi-tools image as well:
Changing it here for the controller:
https://gitlab.com/CentOS/automotive/container-images/ffi-tools/-/blob/main/files/etc/bluechi/controller.conf.d/00-default.conf?ref_type=heads#L17
And adding ControllerPort=8420 here for the agent:
https://gitlab.com/CentOS/automotive/container-images/ffi-tools/-/blob/main/files/etc/bluechi/agent.conf.d/00-default.conf?ref_type=heads#L3

@pengshanyu in case they were running on the same pipeline #630

The disk is full and unrecoverable, so once #630 is fixed, this issue will not occur again

Hi @Yarboa, thanks for the investigation.
Bluechi developer suggested that we change the port from 842 to 8420. Do you think it is safe to change it now? @dougsland @Yarboa

This is the MR to change the bluechi controller port in ffi-tools to 8420
