@smunir Thank you for your reply - I agree with your sentiments regarding support in corporate environment. Xibo is used extensively in the corporate world due to it running on on-premise, supportable hardware/software and this wont change.
Off topic, but Docker EE (enterprise edition) is available on RHEL (and Docker CE is available on CentOS). So the CMS host stack is supportable in the corporate environment. The containers themselves are “black boxes” and therefore should hopefully be permissible.
