Review comment:
typically something like `chmod -R u-w /pulsar` is very expensive from
diskspace consumption perspective since Docker's copy-on-write (COW) solution
must copy the file also when the file permissions are modified. This would
double the disk space if /pulsar contained the files. However, it seems that
files are copied to /pulsar after this command.
