Host Configuration
Redis warns at startup if memory overcommit is disabled, as background saves (which fork the process) may then fail under low memory. This is a kernel-wide setting so it cannot be changed from inside the container - set it on the Docker host instead:
sudo sysctl vm.overcommit_memory=1
echo 'vm.overcommit_memory = 1' | sudo tee /etc/sysctl.d/99-overcommit.conf
