OnlyOffice Integration via Subfolder (Seafile and OnlyOffice Document Server running in Docker)

Seafile Server
1

Hi,

I am running Seafile and OnlyOffice Document Server in Docker. Both have different ip addresses in the same subnet.

As web server nginx is used. Nginx is running as a reverse proxy for Seafile (SSL) and different other services.
nginx is running in a seperate container.

Seafile and OnlyOffice Document Server are running fine.

I followed the instructions in manual for the integration Seafile and OnlyOffice Document Server.

I tried first via Subdomain but the result was alyways a blank page opening a document.

So I tried via Subfolder method. The funny thing what happens is that when opening the OnlyOffice Document Server page via https://seafile.mydomain.com/onlyofficeds/ or https://seafile.mydomain.com/onlyofficeds/welcome as a test, I am being redirected to https://seafile.mydomain.com/welcome and then Seafile is saying web page could not be found.

I checked many times nginx configuration and seafile configuration, restarted both services many times and even docker service itself.

Any help or hint is appreciated.

Thank you
Hubertus

Frankly I think the setup is harder than it looks. Can we check the basics and see if you got on first base?

For example, did you setup your Docker container to run on port 88? Can you see seafile.mydomain.com:88 in a browser?

Also, even if you do not speak German take a look at this video. I found it very useful even though I was still not able to successfully integrate OnlyOffice with Seafile using the Subfolder method.

Just by giving your summary I think you webserver config is wrong.
Please post the only office nginx part.

Hi,

thank you for your help.

As per the Manual do you need

IMPORTANT ! - Trailing slash !

      proxy_pass http://127.0.0.1:88/;

rather than just

proxy_pass http://lan_ip_address/;

in the OnlyOffice Subfolder block?

It depends where the docker container is running. What port is the docker container running on? Why does the reverse proxy have to be on another host?

Hi,

thank you for your answers.

The docker container for the Only Office Document Server is running on port 80. I have an nginx server as a central reverse proxy server running for several services.

The manual recommends port 88 just for the reason that the nginx reverse proxy is running in the same container/vm as the Seafile Server.

Seafile Server, Only Office and nginx are running in its own docker container. All are in the same LAN and “lan_ip_address” stands for the IP address of the OnlyOffice LAN IP address.

Does anybody see a general error in the configuration? It is only altered regarding the port of the Only Office Dcument Server. I tried with port 88. But I got the same result.

Thank you for your help.

Hi,

I tried port 88 and port 80 and both times I could see the Only Office Document server running.

Please try all connection scenarios with nmap and check routes to see if routing works properly.
I guess you are running your containers in a dedicated network, otherwise it’s a serious security flaw.

11

Hi,

the routing works. Thank you for the hint.

I got curious what exactly you mean by security flaw? Thank you for your help.

12

Typo here?

client_max_body_size 100; # Limit Document size to 100MB

Should be:

client_max_body_size 100M; # Limit Document size to 100MB

13

Sorry, I don’t follow. Can you clarify this for me?

Are you saying that Nginx, Seafile and OnlyOffice are running in their own container? I was imagining a plain vanilla setup where Nginx/Seafile were collocated with a Docker container running OnlyOffice DS. Is that what you’re running?

On the other hand, are you running the OODS Docker container on another host on the network?

14

This was still not corrected on the manual? \o/

15

Hi,

nginx, seafile and only office are running in their own containers. nginx is not included in the plain vanilla docker seafile.
All docker containers are in the same network on the same host.

Thank you for your help.

16

thank you for pointing that out. I corrected this in the config.

17

Would you mind, for completeness, putting up the Onlyoffice-related parts of seahub_settings.py that you are using? -Thanks

Have you tried using the Developer Tools (Web Console; Javascript Console) in your web browser(s) to detect the error in the link? In diagnosing blank pages from the Seafile-OODS integration I found many instances of https CallBack errors and other resultant 404 pages. It might be useful in your case to pin point where the error is originating.

Here is a little background on the Callback and the transactions between OODS and server from the OwnCloud/NextCloud perspective. It seems the OwnCloud folks have the same problems integrating OODS as the Seafile folks.

“seafile.domain.com” is substituted with my domain.

Thank you for your help.

I will have a look into it and report.

Thank you for your help.
