I am running shell commands inside my Perl script, but it does not work as
expected. I am in a container with Alpine Linux as my base image.

my Perl version v5.24.0.

perl -e 'my $TEST = `ls -al`; print $TEST'

This prints nothing, but works on another system where I have Perl v5.6.1
on Red Hat Linux.

I had this problem. Some versions of Red Hat have some special kernel (I
didn't investigate what it is). This causes many other distros not to
run on Red Hat Kernel and vice versa. I solved that by running the
container in a vagrant box.
