I am working on an app which is deployed to a Docker environment using read-only filesystems. Prior to deployment we are clearing then warming the cache with:
php bin/console cache:clear --no-debug --no-warmup --env=sandbox
php bin/console cache:warmup --no-debug --env=sandbox
This works for most aspects, and the app functions as expected. However, the logs are filling with warnings about not being able to write entries for OrderedHashMap into the cache:
