Whenever we do publish settings with updated key/value pairs in Tridion Sites 9 we have to do /admin/refresh to clear the cache. It works fine when application is running on single container, but when application is running on multiple containers /admin/refresh will not work as its going to invalidate cache from single container.
Is there anyway I can do cache clear for all the containers?
We are using DXA 2.0.5 Java with Site 9.
In my understanding, DXA caches the resources (jsons and other files) on the filesystem of the webserver. By doing an admin/refresh you instruct the application to reload those resources from the DB. But, this is not a global operation, it only applies to that specific server. Having that in mind, the most straight forward solution is to call the admin/refresh on all the nodes.
If you wish, you could write custom logic to do that for you (you hit a single endpoint, then your code hits the refresh endpoint on all), or logic which would delete the specific resource files from the filesystem (which subsequently makes the framework re-save it to the file system), or some other custom solution.
