Yes, you are right.
afiter fix this, the redis can boot with warning like this,
WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
follow the message to fix it and it's done.

Thanks a lot for this file, it saved me literally hours of work! One correction: Line 76 should be:
entrypoint: redis-server --maxmemory 512mb --maxmemory-policy allkeys-lru- The double dash for the second argument is missing.
