iris00:~/packages/elog> 

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/

<html>redir</html>
HTTP/1.1 200 Document follows
HTTP/1.1 200 Document follows
Server: ELOG HTTP 3.1.5-23df00d
Content-Type: text/html;charset=ISO-8859-1

Pragma: no-cache
Cache-control: private, max-age=0, no-cache, no-store
 

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!

Best,
Enrico

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.

Best,
Enrico

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

Hi Laurent,

Thanks, good point! I'm building a vanilla version (no extra options enabled as I'm using Webserver authentication).

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 :

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.

I'm trying to run elog behind haproxy, but get the error "Invalid Content-Length in header" on posting.

As stated in the manual, haproxy rewrites all headers to lower case.

elogd parses the content-length header case sensitive which is against the HTTP RFC. This might also apply to other headers that get parsed.

For now I'm using the workaround from the manual:

global
  h1-case-adjust content-length Content-Length
  h1-case-adjust content-type Content-Type

backend elog
  option h1-case-adjust-bogus-server
  server elog 127.0.0.1:8080

But as the manual states, this should not be  used as a permanent solution.
