Cognos Analytics

With version 11 I installed and used CA jupiter notebook with RHEL 7 and docker-ce. It was easy to install and worked well.
For CA 12 I decided to go with RHEL 8 and to use Podman. Installation seems easy.

The first problem is that when launching starrtup.sh (as root) at the end I get the message "chown: cannot access '/var/run/docker.sock': Permision denied".
But the two images launch fine and when I type in the browser http://localhost:8000 (or FQDN of the server) I see a nice message: "You are connected to Cognos Analytics for Jupiter Notebnook!".
Great.
Now I'm trying to enable access from my CA server (under Windows).
I added my jupyter server in CA_IIS... script, deleted the gateway configuration in IIS and re-ran the script (IIS configuration looks good). 

Subsequently I opened the rights to the notebook to all authenticated people.
I have a blue wheel that spins for a long time and I get the message: "An unexpected error occurred.Check the Jupyter server logs.".
And there is nothing in the logs folder :(.
I don't really know how to get out of it.
The problem is related to chown on ca_user which does not work in startup?
Otherwise in config.conf there is a new parameter COGNOS_HOST.
In the documentation it is written to initialize it with the same content as "Dispatcher URI for External Application" and as an example we have http://cognos-host:9300, or in Cognos Configuration we have http://cognos-host :9300/bi/v1/disp.
The two servers ping each other. I checked the procedure and configuration several times. I don't work with SSL. Port 8000 is open on the jupyter server. CAF is off.
Has anyone ever run CA 12 (with gateway) and Jupiter on RHEL 8?

Thanks for your help

We're running 11.2.4.1 on podman on RHEL with proxy

We had to make sure that

• hostname part of COGNOS_HOST. in config.conf and 'Jupyter service location' in system config is the same
• proxy forward rules were added: https://www.ibm.com/docs/en/cognos-analytics/11.2.0?topic=cahshs-configuring-apache-http-server-http-server-cognos-analytics
• as for logs, we monitored: podman logs --follow=true  ca_jupyter_hub (e.g. we found a 'cross site scripting' error on starting the notebook server, which led to a timeout in the browser)

Does the notebook container start on trying to open/create a notebook ?

Is there any old containers left that may interfere ?

Or any sock processes  active tha t should not ?

Hi Thomas,

My CA version is 12.0.1
For the host name I use the $hostname variable which returns the same value as the one I have in the system configuration
I use Microsoft IIS and to initialize it I used the script provided by Cognos. I later checked the rules are OK
I have only CA containers. 

When I execute startup.sh at the last I have a message "chown: cannot access '/var/run/docker.sock': Permission denied" and it's very strange because I start it as root. 
With podman logs I have too somme strange "Permission denied". 

I installed the RHEL server twice for testing and both times I got the same result.

Any idea ?
