This limitation should come as no surprise, and it’s hardly a “big” limitation.
Options include building container images which match the host distro, or using a vpp snap image on the host which corresponds to the container images. Given that there are two ways to deal with the situation, pick your favorite and move on.

This is really a big limitation.

I’ve heard that glibc changed in ubuntu 20.04 but I haven’t done any testing with it yet. Note that the binary api also makes use of svm_queue_t.

In svm_queue_t, there are mutex and condvar variables that depends on specified glibc version. When VPP run in host and VCL app run in a docker container, glibc versions maybe different between VPP and VCL app, and then result in memory access error for different size of mutex and condvar. Has anyone noticed this?
