It is a well known fact that there exist trade-offs between fully securiting applications and the applications respective performance. But what if it was possible to have optimally performing applications and maintain proper security guards?

Recently, CRI-O has optimized handling of SELinux labeling of volumes. Before, a large volume would be relabeled for the container so it could access it, but other (potentially malicious) containers could not. This labeling delay would happen for every container creation, and caused timeouts and platform delays.

Join Sascha Grunert and Peter Hunt as they walk through the optimizations, performance implications, and trade-offs of these recent improvements. At the end of the talk, audience members should find out it can be possible get the best of boths worlds with high security and optimal performance.

Session chairs: Michal Ruprich and Lucie Vrtelova
