Development for LHC@home

For me, it looks as if it is working fine,

The BOINC-Client is configured to use my local Squid-Proxy, which worked fine in the last years with ATLAS- and THEORY-Native-Tasks

Now when running Theroy (docker) 7.6.2 I get following messages in the WU-Result-File:

I don't know who has the responsibilty to pass the proxy-setting "down" to the docker / Theory app

Forward a proxy via environment variable.

Thanks Stefan, but first I think it is the job of the Project to enshure that the Master-Configuration from the BOINC-Client is carefully handed over to the Project-App. This has been the same when LHC started to use VirtualBox so I think, they shouldn't do the same mistake a second tine

Second, as an interim-solutions this may be okay, but I'm to stupid to do it as described:

1. Define an environment variable, here: http_proxy=http://proxy:port
2. Export that variable, here via containers.conf
3. Create a script inside the container that reads the variable and does the necessary steps
here: add CVMFS_HTTP_PROXY="http://proxy:port;DIRECT" to /etc/cvmfs/default.local

The script is already available in the Linux app_version.
The Windows app_version just needs an update.

I tried to do this, but I was not able to follow it.

I'm running Windows 11 with Podmann, but

1. Where should I define the environmanet variable ?
   
2. Where can I find the correct containers.conf ? I have 4 of these in different path
   
3. in my boinc-buda-runner I don't have a /etc/cvmfs/default.local. Couldn't find any cvmfs-directory
   

Any ideas ?

It's just one out of many open points that need to be solved before docker/podman based apps are ready for production.
