openshift laravel 5.0 uploaded images deleted after pushing the changes

Every time I push something in openshift, all my uploaded files are deleted. I'm not sure where openshift moved them. All i see on the admin panel is broken images. Anyone encountered this problem?

I've tried linking the public/uploads folder to OPENSHIFT_DATA_DIR using the deploy script, unfortunately it didn't work. What's wrong with my deploy script?

ln -sf ${OPENSHIFT_DATA_DIR}uploads   ${OPENSHIFT_REPO_DIR}public/uploads
ln -sf ${OPENSHIFT_DATA_DIR}levels   ${OPENSHIFT_REPO_DIR}public/levels
ln -sf ${OPENSHIFT_DATA_DIR}messages   ${OPENSHIFT_REPO_DIR}public/messages
ln -sf ${OPENSHIFT_DATA_DIR}cards   ${OPENSHIFT_REPO_DIR}public/cards
