Can't get folder inode inside docker container

I’m experiencing some issues with the Travis docker infrastructure.
Calling ls -i or stat inside the archilinux docker image results in Operation not permitted while on my local machine it works fine {os:archlinux,docker:19.03}.
Here’s some tests I’ve made
And the errors they causes
This prevents me from building lib3ds wich has this crazy check in the configure

ac_pwd=`pwd` && test -n "$ac_pwd" &&
ac_ls_di=`ls -di .` &&
ac_pwd_ls_di=`cd "$ac_pwd" && ls -di .` ||
  { echo "$as_me: error: Working directory cannot be determined" >&2

Find out which system call is responsible for that and give the container the necessary permissions.

Thanks, now it’s so oblivious :smirk:
For the time being, I’ve added --privileged to docker run here to have the Arch-Linux container behave congruent with local system build.

You can see system calls with strace. It will make it clear which one returns “operation not permitted”.

Thanks Already did this. Smal caveat was that to be able to use strace inside a container I have to first add CAP_SYS_PTRACE capability to docker run.
