I'm currently working on deploying Drupal8 on Openshift to achieve horizontal scaling, but I hit a problem.
On a single pod (ie: "server" running drupal"), everything seems to be ok so far. But when I'm deploying a new pod, it tries to load the private files (/sites/default/files) using the same path as the first pod.
I guess it's because something is cached in the DB since "Clearing all cache" fixes it.
Is there something in the configs I can do to prevent this behaviour ? And do you think of something I should be warned about when trying to achieve horizontal scaling ?
