Also, you have the option to rebuild RPM from SRPMS or SOURCES via ELOG buildrpm script.

You will need to install rpmbuild tools...

Options (ldap, kb5, etc) can be set from options or by editing defaults.

Enrico,

When using RPM in OpenShift, I guess all the RPM dependencies are correctly installed.

FYI, I met a problem with elogd docker built with alpine Linux image and running on Synology NAS (x86_64). The ImageMagick dependencies libs provided by alpine for X86_64 are optimized for better CPU than mine with AVX2 (or something like that), and elogd failed to save a log with any enclosure (core exit, bad instruction), as some thumbnails are generated while saving.

As I didn't find any easy workaround w/o rebuilding all IM libs, so I switch to Debian images more conservative in CPU optimization, but bigger :-( before to switch to minideb that's run fine in my case.

It's not easy to debug in container w/o making one specially for that, so you should try to build a docker based on alma9 image, compiling elogd from sources (you can follow https://github.com/loll31/elog-ldap for the process).

Good luck

 

NB : The ldd result from my minideb Docker :

Hey Enrico,

Do you activate also all options with your build ? (pam/ldap/kb5/ssl)

Can you compare ldd command results on elogd binaries builded by yourself and the one from RPM ?

$ ldd /path/to/elogd

Also, size of both elogd files.

Regards

Sorry for posting again but something else came up.

Actually, building from source (elog-3.1.5-1.tar.gz) works just fine on OpenShift too.

The problem described below only happens when installing the packaged binary elog-3.1.5-20240226.el9.x86_64.rpm.

Enrico

Hello!

We're setting up ELOG on OpenShift. ELOG is installed on a Alma Linux 9 image. The container and the elog demo works fine executing the docker image locally.

When deployed on OpenShift, we get a weird response, that results in a 502 Bad Gateway. The broken response looks like:
 

# curl -v -H 'X-Forwarded-User: enrico.gamberini@cern.ch' https://psi-elog-container2-elisa-epdtdi.app.cern.ch/demo/

Notice the HTML tag before the HTTP header, as well the duplicate HTTP header.

I understand that it might be difficult to reproduce, but any input would be very welcome!

Thanks!
