Redirect to knowage-vue doesn't work

[taurus227]

I managed to get it to run with docker-compose up -d by making the following changes:

Our external port 11081 is redirected to 8081 on this host.
The secretRequired="false" added to AJP was needed to fix this exception:

30-Apr-2021 05:58:53.721 SEVERE [main] org.apache.catalina.core.StandardService.startInternal Failed to start connector [Connector[AJP/1.3-8009]]
        Caused by: java.lang.IllegalArgumentException: The AJP Connector is configured with secretRequired="true" but the secret attribute is either null or "". This combination is not valid.

This got me to the login screen.
The host_url was an attempt to fix the problem described below, but it didn't do anything.

After I login as biadmin, I get redirected to http://my.domain.com:11081/knowage-vue and get the error:

The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

How to fix this?

Hi Robert,

thank you for you report: we have seen the same problem in our test environments and you are working on it.

As you can guess, the -SNAPSHOT version could have this type of problem. In particular I will check the content of the image because I suppose that the CD process is having a wrong behavior.

Just a note: the host_url variable is deprecated and we did a lot to remove all references from our code.

I will evaluate your patch but I'm pretty sure we already have problems before the runtime.

Hi Robert,

if you pull the new 8.0.0-SNAPSHOT I think we have resolved the problem.

[taurus227]

OK, so now it's running, everything is up:

I cannot see any errors in the console output of docker-compose up, but if I try to log in as biadmin I still get redirected to /knowage-vue and all I see is this:

Also, it keeps outputting the same 6 messages from knowager_1 and knowagepython_1 in what seems like an infinite loop:

Logs from knowager_1 and knowagepython_1 are perfectly normal because of the health checks in Python's Dockerfile and R's Dockerfile.

About the UI, you are using a custom hostname different from localhost:8080, isn't it? We will investigate, probably you could see some errors in your browser's console.

Previously there was an error related to quartz, but executing "the creation scripts provided for the DBMS in use" fixed it. At this moment the logs do not show errors, but

[zengxc-1996]

I also encountered this problem during deployment. How can I solve it?

[kerny3d]

Thank you for all your report.

Please remember that the 8.0.0-SNAPSHOT version is a development version and we use it to discover and work on issues.

And please remember that if you want a production-ready version please use a non SNAPSHOT version.

[zengxc-1996]

Thank you for your reminding. It is very important to me.

Should I use this mirror:
docker pull knowagelabs/knowage-server-docker:latest
Instead of:
docker pull knowagelabs/knowage-server-docker:8.0.0-SNAPSHOT

[kerny3d]

I would suggest you the last non-SNAPSHOT major tag like 7.4 then:
docker pull knowagelabs/knowage-server-docker:7.4

[zengxc-1996]

Thank you for your advice. I'm trying my best.
