Valkey socket bind permission denied

[aliismayilov]

It seems to be there is a permission issue when trying to use a socket for valkey server container:

$ docker run -it --rm valkey/valkey valkey-server --unixsocket /run/valkey.sock
1:C 07 Oct 2024 07:24:29.919 # WARNING Memory overcommit must be enabled! Without it, a background save or replication may fail under low memory condition. Being disabled, it can also cause failures without low memory condition, see https://github.com/jemalloc/jemalloc/issues/1328. 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.

/run/valkey.sock is the current default suggestion.

We need to mount a volume and use a valkey.conf file to run the server with the configs and the also a valkey.soc file with the right permissions to use a socket for valkey server container:

I make a tmp/valkey.conf file like

unixsocket valkey.sock
unixsocketperm 700

also created tmp/valkey.soc and change file permission to 700

chmod 700 tmp/valkey.soc

you can run the following commands

docker run -d \
-v /tmp:/usr/local/etc/valkey \
valkey/valkey valkey-server /usr/local/etc/valkey/valkey.conf;

valkey-server logs:
