## 🍰 Pullrequest
This will migrate our assets to an objectstorage via S3.
Before this PR is rolled out, the S3 credentials need to be configured in the respective infrastructure repository. The migration is implemented in a backend migration, i.e. I expect the `initContainer` to take a little longer but I hope then it's going to be fine. If any errors occcur, the migration should be repeatable, since the disk volume is still there.
### Issues
The backend having direct access on disk.
### Todo
- [ ] Configure backend environment variables in every infrastructure repo
- [ ] Remove kubernetes uploads volume in a future PR
