RedisCluster - 7.2.5 not starting #174
Description
Introduction
I've been using grokzen's RedisCluster for the past few years. It was working fine so far. However once I've tried to migrate to 7.2.5 version it stopped working and it seems he can't even form a cluster.
Environment
- docker-redis-cluster version: 7.2.5
- redis-server version: 7.x
- git hash (If applicable):
- CLI command used to build the container: docker run -e "IP=0.0.0.0" -p 7000-7005:7000-7005 grokzen/redis-cluster:7.2.5
Steps to Reproduce
It's enough to run this command: docker run -e "IP=0.0.0.0" -p 7000-7005:7000-7005 grokzen/redis-cluster:7.2.5
Expected Behavior
Fully formed/operable Redis cluster to which I can connect.
Observed Behavior
It seems that the Redis Cluster cannot be formed. Moreover, it looks like the individual Redis nodes are not starting up correctly. To support my theory, I paste the logs of Docker Redis cluster below:
docker run -e "IP=0.0.0.0" -p 7000-7005:7000-7005 grokzen/redis-cluster:7.2.5
-- IP Before trim: '0.0.0.0'
-- IP Before split: '0.0.0.0'
-- IP After trim: '0.0.0.0'
bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)
Using redis-cli to create the cluster
Could not connect to Redis at 0.0.0.0:7000: Connection refused

There are multiple strange issues. The first one which troubles me is:
Using redis-cli to create the cluster
Could not connect to Redis at 0.0.0.0:7000: Connection refused
Which would indicate that the 7000 node is not running at all. I've verified that by going into container itself and checking the open ports - there is no port opened, suggesting that all the nodes are down.
Then according to those logs, it's clear that the nodes are in some kind of a loop, trying to start but somehow it fails.
There is also this LOCALE error. However, I don't believe that it causes Redis nodes to fail.
