Recreating compose_app_1         ... done
Docker development environment setup complete.

@piotrkwiecinski You may also remove the below redis setting part

echo "Enabling Redis for cache..."
bin/clinotty bin/magento setup:config:set --no-interaction --cache-backend=redis --cache-backend-redis-server=redis --cache-backend-redis-db=0

echo "Enabling Redis for Full Page Cache..."
bin/clinotty bin/magento setup:config:set --no-interaction  --page-cache=redis --page-cache-redis-server=redis --page-cache-redis-db=1

echo "Enabling Redis for session..."
bin/clinotty bin/magento setup:config:set --no-interaction --session-save=redis --session-save-redis-host=redis --session-save-redis-log-level=4 --session-save-redis-db=2
