The Github page mentions that postgres, nginx and elasticsearch aren't currently supported by the gVisor kernel (or pseudo-kernel?). Those are significant, but they shouldn't be showstoppers for a lot of deployments. They list each of these shortcomings as bugs, so hopefully there's a real effort to support the capabilities required by those applications.
Also, I'd like to see what the performance impact is like. What types of applications would suffer the worst performance running on gVisor? What applications will be the least affected?
- hacknat 8y agoIt’s likely that web apps and servers will be least affected, I cannot imagine the performance on databases being good.
- loudmax 8y agoYou're right, the Github page says as much: > gVisor may provide poor performance for system call heavy workloads. Incidentally, I find the description on Github much more interesting than the one on the Google Blog: https://github.com/google/gvisor https://github.com/google/gvisor
