Issue with docker deployment: Apache proxy returning 404 error

[Filipe Cunha]

Hi everyone,

I want to deploy a Docker image of Inception on my server, at example.com/inception. As port 8080 is already taken, I redirected the container port to 8081:8080. Then, I created a reverse proxy in the Apache config file:

<VirtualHost *:80>

ProxyPreserveHost On

ProxyPass /inception http://localhost:8081
ProxyPassReverse /inception http://localhost:8081

...

</VirtualHost>

I also created a settings.properties file and added the following:

wicket.core.csrf.accepted-origins[0]=example.com

wicket.core.csrf.accepted-origins[1]=https://example.com

However, when accessing example.com/inception, the website returns a 404 error and redirects me to example.com/login.php instead of example.com/inception/login.php. When I manually change the URL to example.com/inception/login.php, the Inception login page loads. However, when I attempt to login, it redirects me to example.com (another application) instead of example.com/inception.

I also tried adding the following line to the settings.properties file, but still no luck:

server.servlet.context-path=/inception

I suspect that the issue lies in how the application handles redirects, possibly ignoring the /inception path prefix. Any insights or suggestions would be greatly appreciated!

Thank you in advance for your help!

Have you checked if the settings file is actually loaded? There should be a line like this in the console/log:

```
INFO [main] [SYSTEM] boot - Settings: /path/to/inception/settings.yml (file exists)
```

Also, later, there should be a line like this:

```
[SYSTEM] boot - You can now access INCEpTION at http://localhost:8080/inception
```

In that last line, does it show `/inception` at the end or not?

Cheers,

Yes, both lines appear when starting inception.

Found the issue after some struggle: the proxy should have the /inception prefix.

<VirtualHost *:80>

ProxyPreserveHost On

ProxyPass /inception http://localhost:8081/inception
ProxyPassReverse /inception http://localhost:8081/inception

...

</VirtualHost>

It works now. Thank you, Richard!

Hi, it seems I'm having another problem that might be related to connectivity configurations. 

When I try to export my project, nothing happens, there is no loading bar and I cannot download my project.
My console is returning some errors:

I went to the administration tab and found the following:

Here you have the apache virtual host:

Any ideas?

Thank you,

Hi,

in the ProxyPassReverse, you likely have to use https for the external URL:

ProxyPassReverse /inception https://foo.bar.com/inception

Also, make sure to add the CSRF settings:

https://inception-project.github.io/releases/32.2/docs/admin-guide.html#_csrf_protection

Once done, check the Administration page again if the situation has improved.

I had already configured my CSRF. Here you have my settings.properties

I also changed the ProxyPassReverse as you requested using the external url:

 

Then I restarted the Apache server, but the errors displayed on the inception administration page remained the same :/

Any other ideas?

I was able to fix the CSRF error by correcting the settings.properties files. However, the other two errors remain. The browser console is still returning the WebSocket error.  I tried several different Apache configurations but had no luck. I'm really lost here... 

I also noticed that, even though the project export button won't allow me to download the project file, when I press it I get the following logs inception terminal: 

It seems that the server is doing something, but then nothing happens on the browser :/
