@irreleph4nt said in Documentation on kopano-web (kweb):

@longsleep It looks like the approach you mentioned injects additional parameters into the kopano caddy vhost configuration. Is there a way to actually define another vhost alltogether and run it via kweb? I am thinking about this as I’d want PHP FPM / FastCGI as an example if not for kopano, then for other vhosts at least.

The example from earlier does just that. It ends the configuration for the kopano vhost, and starts a new one for nextcloud. Its a hackish way but works.

irreleph4nt

I missed the closing breaket just above the example.com string - my apologies. What it looked like to me was that everything would hence go into the same vhost but of course, you are right. This way a new vhost is added to the config kweb uses. Kinda neat, but hacky. :)

@irreleph4nt said in Documentation on kopano-web (kweb):

when I use caddy mode I have to turn off tls for kweb entirely

that mas maybe easy to misunderstand. kweb has a native option to turn off tls. you do only need to use the “caddy mode” when you want to completely use your own configuration file. In which case you will no benefit from the builtin configuration for meet, konnect, …

@irreleph4nt said in Documentation on kopano-web (kweb):

Does proxying to kweb have any negative impact on it serving everything I need for kopano to work?

since you add another hop this will probably give a small performance penalty.

irreleph4nt

@fbartels Thank you for clearing up my misunderstanding. One last question, please:
Does kweb come with default configration for z-push built-in or do I need to add z-push configuartion myself, through the extra.conf file for example?

fbartels

@irreleph4nt no, there is no native configuration for z-push yet (only the legacy proxy option). If you have a working setup we are of course open to include it.

irreleph4nt

@fbartels @longsleep

So this is where my experiement with kweb ends. I am pretty disappointed because I can’t even get it to start (aka, “serve”). As you can see in below systemctl output, the “setup” command in ExecStart finishes successfully but the “serve” fails with a coredump.
In case you want to debug this, I’ll dump a truckload of info below, including my build script on Arch Linux, relevant filesystem hierarchy and systemctl output as well as a dump file.

OS: Arch Linux x64
Software: minimal base install as per ArchWiki: base group, openssh, network, time and locale config
Kopano packages (all compiled from source; git master): kopano-core, kopano-grapi, kopano-kapi, kopano-kdav, kopano-konnect, kopano-kweb, kopano-kwmserver, kopano-meet, kopano-webapp, kopano-webapp-plugins (all), libkcoidc, php-kopano-smime, z-push
kweb configuration: vanilla, no changes to .cfg file

Thanks for getting back to us. Unfortunately the core file is not really useful without the exact binary and even if i had it i doubt it would yield more information. You did not post the output of the actual command (like from systemd journal) - is that because it did not give any output?

From your build script i see that you use the systemd service file shipped with the source tree. I find it much more likely that the problem is t there since it uses systemd features like sandboxing and dropping of caps. Please check that the systemd service parameters there are compatible with your distro and the environment/kernel you are running inside.

irreleph4nt

@longsleep
Thanks for replying!

I have restarted the machine in question and issues another “systemctl start kopano-kwebd”, which produces the following in the journal, kwebd log files remain empty: link to bpaste (expires 2019-03-25 19:57:14).

Regarding the systemd service file, I am investigating this and asking for help on my distro’s channels. kwebd 's behaviour does not change though, even if I am calling the binscript directly with “/usr/sbin/kopano-kwebd serve”. The terminal only reads

Trace/Breakpoint triggered (core dump written)

EDIT: In hope this helps at all, I have uploaded another core dump as well as the binary to my nextcloud. See here: link to folder

irreleph4nt

EDIT:
The below is fixed. After some investigation and multiple re-compiles of kweb, the problem revealed was that your software does not support PIC/PIE (see Wikipedia for some additional background and why PIC/PIE is a good idea). Compared to my build script posted above, I have exchanged go-pie with go but left the GOFLAGS untouched. I have also tried the -buildmode=pie flag in combination with vanilla go, but that resulted in the same segfault as compiling with go-pie directly. My next post in this thread will be about kweb configuration.

@longsleep @fbartels

You probably don’t have to look into this much further. I have done something that on the surface seems very stupid: replacing my own binaries for kweb and konnect (which exhibited the same issues) with the pre-compiled ones from the community Debian packages. And … surprise … they “work”, i.e. both services start in a more or less operational state.

I must have done something wrong in my build script by following my distro’s go packaging guidelines. Unfortunately, I am not a go developer so I am having a hard time spotting what exactly causes my binaries to misbehave. Compared to your instructions on github, I have introduced only a very small number of changes:

I am calling dep ensure before I start the build
I have built towards go-pie instead of go to create secure binaries
I have introduced additional GOFLAGS to enable RELRO support and trimed the build path from binaries, all in one command:
export GOFLAGS="-gcflags=all=-trimpath=${PWD} -asmflags=all=-trimpath=${PWD} -ldflags=-extldflags=-zrelro -ldflags=-extldflags=-znow"
(this is obviously issued before the build itself starts)

If you can see anything in the above list that is likely to cause issues, please by all means shout. :)
I’ll keep tinkering with this for a bit, maybe I find something by accident?

Thanks for following up. I had a look and this is because kweb (and all most other Go software by Kopano) is built as self contained static binaries with zero external dependencies. If you look at the Makefile you will see that various additional flags are passed when building to create reproducable binaries with zero (not even libc) dependencies.

So your exact issue is caused by -extldflags -static which is used in the Makefile. This is not compatible with -buildmode pie and the resulting binary is broken since PIE relies on features of the external linker.

We might want to expose better control to the build parameters though environment variables in the future - i need to think about that a bit. For now, you have to patch the Makefile to get rid of the part which forces static self contained binaries if you want to build a PIE.

If you build with PIE you rely on the cgo runtime which is also mostly disabled for Kopano Go software for the same static binary reasons. So make sure to also set CGO_ENABLED=1 when building to avoid potential problems.

you do not really need to extract these from the debian packages btw. you could also simply grab them from https://download.kopano.io/community/kweb:/ and https://download.kopano.io/community/konnect:/

irreleph4nt

@longsleep
Thank you so much for this detailed explanation! Once I have my setup running I’ll definitely return to the PIE problem and apply all the knowledge you have shared here. :)

@fbartels
You are right, I could have used the relevant tar files on the community server as well. That was probably my brain demanding a nap. Thanks for pointing it out!

I have hit another road block by now that might have to do with kweb, so I am shamelessly plugging it in this thread.

This seems ok - why would it return something else? That URL is not a valid endpoint of the gc API. Try an endpoint with exists - for example /api/gc/v1/me (it will return 403 unless you pass a valid access token with bearer auth).

Maybe this is related to systemd sandboxing. The kapi systemd service shipped with the source tree uses full isolation and drops all caps. From the systemd docs ProtectSystem=full should only make /usr /boot and /etc read-only though. So not exactly sure what is going on here.

Good point, We should probably add this use case to the docs somewhere or even include it by default.

In the meanwhile, kweb has learned (0.6.0 and later) some additional configuration directives which make it easier to configure fastcgi apps like Kopano webapp. Use something like this:

alias /webapp/ /usr/share/webapp/
fastcgi2 /webapp/ 127.0.0.1:9000 php {
  without /webapp/
  root /usr/share/webapp/
}
folderish /webapp

Add these directives (and potentially others, as desired) to the extra.cfg which by default (if you use the binscript from the source tree) is loaded from /etc/kopano/kweb/extra.d/extra.cfg. Of course this requires a running php-fpm in this example at 127.0.0.1:9000. Unix sockets also would work. Take a look at the Caddy server fastcgi directive which is mostly the same as kweb’s fastcgi2.

Thank you very much for helping me figure all of this out. I really do appreciate it!
Meanwhile I have great news, as with your help I have gotten the following packages to work:

kapi
grapi
konnect
kweb
kwmserver (and by extension, meet)

kweb makes setting all these up a very easy exercise and I am impressed by it’s performance so far! I have also collected some feedback which may be useful to you:

The “scope” files (i.e. the yaml files) that are used between some of the kopano packages, what they are needed for and how to set them up correctly is not documented anywhere. Readmes of several packages you provide mention that working examples should have been provided with the docs of the package but I have had a very hard time actually finding any files that did not just contain dummy data. Setting up some dedicated documentation for them would be very useful.
The endpoints and rewrites built into kweb are not documented which made it very hard to figure out how to access any of the webapps. Had you not helped me on the forums here, this would have been impossible to figure out. Documentation in general is very scarse when it comes to kweb.
Even though you do not support subdomains out of the box, making the ACME request you use for letsencrypt automation configurable would be a huge win.
The new grapi repository, or rather its Readme and requirements.txt, are not calling out all the python dependencies to make the software work. python-xapian for example is not mentioned.

The only thing remaining for now is kdav, which for the life of me I can not get to work with kweb or without. Using an alias directive similar to the ones you suggested before doesn’t work. Via the apache example config on github I was able to access the SabreDav landing page but even then there is a bug which prevents it’s usage:

The docs and config make you change the DAV URI but when set to the path that leads to kdav (i.e. /usr/share/webapps/kopano-kdav/), the example apache setup errors out after login prompt with something along the lines of The requested path '/' is outside of the base URI of '/usr/share/webapps/kopano-kdav/'which I assume happens due to the rewrite in the apache config. When the DAV URI is changed to /, I can get to the SabreDAV overview. However, trying to add a contact via CardDav in Evolution then comes back with an access denied error:

192.168.0.1 - testu [24/Mar/2019:23:12:22 +0100] "PUT /9321199165cf935314012bbf955dd0c94f13f18c.vcf HTTP/1.1" 403 330 "-" "Evolution/3.30.5"

Hi @irreleph4nt,

great to hear that you got it running on Arch.

The documentation at the moment indeed focuses on getting stuff running based on our packages (which then auto create the needed files for you). Endpoints for Meet itself are documented in its manual. The endpoints of the rest api are indeed not explicitly documented (well they are actually mentioned in https://stash.kopano.io/projects/KC/repos/kapi/browse/README.md), but these are also not really relevant for the normal end user.

I don’t think grapi itself depends on python-xapian. this could come from python-kopano.

The best thing would be if you could open a pr with your proposed documentation addition (e.g. to the individual readme files). I am not quite sure if you pull your code directly out of our Bitbucket instance, but we also mirror our code to github (at https://github.com/kopano-dev) where you can easily open a pr (or an issue if something isn’t directly clear).

The only thing remaining for now is kdav

I would recommend to open a dedicated topic for this, Kdav has primarily been tested with the apple client suite, it may be an off standard behaviour of Evolution you are tripping over.

PS: not quite sure if I mentioned this before but a good learning piece are the docker images at https://github.com/zokradonh/kopano-docker. for konnect and kwmserver this is using the official docker containers, which means that a lot of the configuration is then done in the dockerfile or the accompanying startup script. kdav is also part of this setup.
