Hi @sybghat ,
There is no “official guide” for supporting CentOS 8; so as @amitta suggests, your best bet is to share your issues and experiences with the community.
The core team use a few difference operating systems, as well as different docker containers, but most of our test environments are based on Ubuntu 18.04. I am curious to know what is motivating you to switch to CentOS 8?
Kind regards,
Phil
