Differences betw RHEL 8 & 7 in terms of hardenings & impact to its container VMs
Q1:
Is there any hardening guide for RHEL 8?
If there's none, can I assume it's very close to RHEL 7's hardenings?
Then I'll ask vendors to harden RHEL 8 as per CIS RHEL7's benchmark.
Q2:
We're hosting docker/microservices in an RHEL host: previously the
vendor tested using RHEL7: can I safely say it makes no difference/
impact to the services/app whether we use RHEL 7 or 8?
Q3:
at the VMs level is there any difference/impact? The docker
instances is spinned from the various Ubuntu, Debian images,
so I'm guessing it doesn't matter which version of RHEL runs
on the VMs

>RHEL 8 uses a Kernel with correct namespace implementation, which all container systems require.
Can point me to a link/article which indicates container systems require this namespace implementation?
