Tips on how to trace executables with podman buildx build via Podman Desktop on macOS?

[sanmai-NL]

I want to use e.g., QEMU_STRACE or plain strace to trace calls to libc functions by a process launched as part of the build. But I'm not sure how to make this happen without experimenting too much. Who knows already?

The following doesn't work when issued from the remote side (macOS).

podman \
  --log-level debug \
  buildx \
    build \
      --cap-add=SYS_PTRACE \
      --cache-from=localhost/test \
      --file=Containerfile \
      --logfile=podman-build.log \
      --tag localhost/test:dummy \
      .

+ strace pdm build --no-clean --verbose
/usr/bin/strace: test_ptrace_get_syscall_info: PTRACE_TRACEME: Function not implemented
/usr/bin/strace: ptrace(PTRACE_TRACEME, ...): Function not implemented
/usr/bin/strace: PTRACE_SETOPTIONS: Function not implemented
/usr/bin/strace: detach: waitpid(353): No child processes
