mysql-tuner / perl error message: diagnostics

[jonasjonas]

Hi, thanks for providing the mysql-tuner docker file.

At the moment I am unable to run it, because its seems that some perl dependency is missing:

couldn't find diagnostic data in /usr/share/perl5/core_perl/pods/perldiag.pod /usr/local/lib/perl5/site_perl /usr/local/share/perl5/site_perl /usr/lib/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib/perl5/core_perl /usr/share/perl5/core_perl /mysqltuner.pl at /usr/share/perl5/core_perl/diagnostics.pm line 259, <POD_DIAG> line 711.
Compilation failed in require at /mysqltuner.pl line 45.
BEGIN failed--compilation aborted at /mysqltuner.pl line 45.

All I could find was, that the perl installation would be incomplete. But reinstalling perl did not seem to help.

Maybe it is a problem with the latest alpine version?

Ah, too early:
It seems, that there is a dependency missing.

If one adds perl-doc to the Dockerfile it works again.

apk --update add mysql-client perl perl-doc

@jonasjonas sorry for the late reply on this -- looks like I didn't have notifications enabled for this repo.

Thanks for the issue report and for finding the solution here! I've just pushed a changeset for adding perldoc (23a59b5) which should be live on Dockerhub shortly. Please let me know if you continue to have issues!
