Invalid Locale_Name on latest image 7.2.5

[yisraelU]

Environment

• docker-redis-cluster version: 7.2.5
• docker compose : v2.26.1-desktop.1

Service declaration in docker compose file

  RedisCluster:
    restart: always
    image: grokzen/redis-cluster:7.2.5
    ports:
      - "30001:30001"
      - "30002:30002"
      - "30003:30003"
      - "30004:30004"
      - "30005:30005"
      - "30006:30006"
    environment:
      - IP=0.0.0.0
      - INITIAL_PORT=30001
      - DEBUG=true
     ```


### Steps to Reproduce

1. docker-compose up


Expected : The container to run with redis-server services running per cluster config


Happened: The container runs and I can see all 6 redis-server instaces start up and they all fail with 
```RedisCluster-1  | 67:M 20 Aug 2024 16:54:16.502 # Failed to configure LOCALE for invalid locale name.

I can also see this warning upon startup

I believe that is the cause .

The locale is not successfully installed at

docker-redis-cluster/Dockerfile

Line 17 in 7922e1f

RUN locale-gen en_US.UTF-8

If I exec into the container and run the same locale-gen command it fails.

To rectify it , I needed to run this instead

echo "en_US.UTF-8 UTF-8" >> /etc/locale.gen
echo "LANG=en_US.UTF-8" > /etc/locale.conf
locale-gen en_US.UTF-8

Once running that and restarting the container , everything worked correctly.

Summary: locale-gen en_US.UTF-8 is failing because it is not found in the config files, therefore this results in the servers not starting

We have the same issue, and the above fix did seem to solve it for us, as well. Thanks @yisraelU

Any chance to get this fixed in the main image? @Grokzen

You can find it here, tag 7.2.5 https://hub.docker.com/r/neohq/redis-cluster/tags

I created a MR though I'm not sure it's enough?

Edit: @neohq just saw your code. Maybe if you created a PR it would speed up the fix?

I'm also running into this.
