You could also add a comment like here to explain that we can set: DIRACX_SERVICE_AUTH_REVOKED_REFRESH_TOKEN_RETENTION_DAYS and DIRACX_SERVICE_AUTH_COMPLETED_FLOW_RETENTION_MINUTES to tune the clean up by the cronJob.

I think there was a confusion here. I just saw that you added the cron job in k3s/manifests, but I think it should go in diracx > templates > diracx > clean-auth-db

[HeloiseJoffe]

Yes I know I'm actually changing it

The pipeline is failing because the architecture diagram has changed with the addition of the new CronJob.
Here is the newly generated diagram:

Could someone with CERN access upload it to replace the current one?

Thanks @HeloiseJoffe, I just have very minor comments 🙂
@chrisburr could you explain me how we are supposed to upload the new diagram please?

The diracx related PR has been merged. I think we now need to wait for a new diracx release within the charts to merge this one I guess, because the cleanup function does not exist yet.
