We are reviewing the possibility of installing KernelCare on the VMs that we have running a Kubernetes Cluster using Docker. Prior to doing this, we want to know if KernelCare would have any impact or security issues. Has it been testing on servers running Containerization? Doing due diligence prior to moving forward.
Yes, it is very popular in environments with containers. We have a lot of people using it with their Virtuozzo install, as well as Proxmox VE.
It helps as otherwise, you need to restart tons of containers (or migrate them, which is not always possible)
We have quite a few Docker customers as well, but it is impossible for us to know if you are running RHEL7 kernel for docker or not.
The main reason people using it is to remove the need to to reboot the server due to security issues.
