On Truenas SCALE the following occurs (even with v2.0.6):

You can try adding SHOW_OUTPUT=TRUE as an environment variable from the upstream base image (tiredofit/alpine) and it should give you reasons as to whats happening with those binaries..

2022-12-18 19:49:38.743740+00:00 BackupPC should run as a dedicated user with limited privileges.  You
2022-12-18 19:49:38.743752+00:00 need to create a user.  This user will need read/write permission on
2022-12-18 19:49:38.743764+00:00 the main data directory and read/execute permission on the install
2022-12-18 19:49:38.743788+00:00 directory (these directories will be setup shortly).

2022-12-18 19:49:38.744069+00:00 BackupPC has SCGI and CGI perl interfaces that run under Apache.  You need
2022-12-18 19:49:38.744081+00:00 to pick which one to run.
2022-12-18 19:49:38.744092+00:00 2022-12-18T19:49:38.744092917Z
2022-12-18 19:49:38.744104+00:00 For SCGI, Apache uses the scgi_mod module to communicate with BackupPC_Admin_SCGI,
2022-12-18 19:49:38.744127+00:00 which handles the requests.  This allows Apache to run as a different user as
2022-12-18 19:49:38.744140+00:00 backuppc.  To use SCGI you need to set SCGIServerPort to any spare
2022-12-18 19:49:38.744152+00:00 non-privileged TCP port number.  A negative value disables SCGI.
2022-12-18 19:49:38.744163+00:00 2022-12-18T19:49:38.744163963Z
2022-12-18 19:49:38.744185+00:00 ** Important security warning!!  The SCGIServerPort must not be accessible by
2022-12-18 19:49:38.744197+00:00 ** anyone untrusted.  That means you can't allow untrusted users access to the
2022-12-18 19:49:38.744209+00:00 ** BackupPC server, and you should block the SCGIServerPort TCP port from

2022-12-18 19:49:38.744253+00:00 The traditional alternative is to use CGI.  In this case, an executable needs
2022-12-18 19:49:38.744265+00:00 to be installed Apache's cgi-bin directory.  This executable needs to run as
2022-12-18 19:49:38.744277+00:00 set-uid backuppc, or it can be run under mod_perl with Apache
2022-12-18 19:49:38.744300+00:00 running as user backuppc.
2022-12-18 19:49:38.744313+00:00 2022-12-18T19:49:38.744313412Z

2022-12-18 19:49:38.744374+00:00 BackupPC's CGI and SCGI script need to display various PNG/GIF
2022-12-18 19:49:38.744387+00:00 images that should be stored where Apache can serve them.  They
2022-12-18 19:49:38.744399+00:00 should be placed somewhere under Apache's DocumentRoot.  BackupPC
2022-12-18 19:49:38.744411+00:00 also needs to know the URL to access these images.  Example:
2022-12-18 19:49:38.744430+00:00 2022-12-18T19:49:38.744430601Z

2022-12-18 19:49:38.744454+00:00 URL for image directory: /BackupPC
2022-12-18 19:49:38.744466+00:00 2022-12-18T19:49:38.744466312Z
2022-12-18 19:49:38.744478+00:00 The URL for the image directory should start with a slash.
2022-12-18 19:49:38.744497+00:00 2022-12-18T19:49:38.744497261Z

Can zabbix be disabled?

sigmoidal commented 1 year ago

@tiredofit thanks for the hint.

Ok, I found the problem. It has to do with Perl pragma to restrict unsafe constructs being enabled, which rendered my config.pl problematic, because they did include unsafe constructs. This is because I copied the config.pl file from other systems where this is not enforced. (I've have been using these configs for 15 years, but upstream the defaults changed)

Effectively, for anyone experiencing this or similar, the config.pl has to be updated to include safer syntax. For example:

$Conf{CgiNavBarLinks} = ( .. );

will cause the docker container's backuppc daemon to hang, while updating it to:

$Conf{CgiNavBarLinks} = [ .. ];

will work. Check the upstream BackupPC config.pl to find out the right syntax of the defaults: https://github.com/backuppc/backuppc/blob/master/conf/config.pl

sidenote: for those looking, zabbix can be disabled by using the env variable: ENABLE_ZABBIX=FALSE

tiredofit commented 1 year ago

Great! Didn't realize that this is in a software catalog somewhere..

In the next versions of my base images the ENABLE_* variables are going to disappear - You may want to switch it off instead with the newer format CONTAINER_ENABLE_MONITORING=FALSE.

sigmoidal commented 1 year ago

Thanks, I switched the env variable, works nicely. If time allows, it may be useful to document on github some of these (and other) env variables that are set in the image.

tiredofit commented 1 year ago

There are quite alot. Check out the README, specifically the section where it talks about the various base images used in order to build this one..
