We have docker files which based on alpine linux. I want for the built container to check the version of the musl library , I mean run the container and and in RT check the musl version how can I do that ?

I've tried something like

libc itself is an executable. You can run it and the usage message will print out the version:

/ # /lib/libc.musl-x86_64.so.1
musl libc (x86_64)
Version 1.1.24
Dynamic Program Loader
Usage: /lib/libc.musl-x86_64.so.1 [options] [--] pathname [args]
