Redis: `Cannot assign requested address` with default config in Ubuntu 18.04 docker image

[ShockwaveNN]

Hi there, I'm not pretty sure that is bug in redis and not in Ubuntu image or Docker itself, but I feel like I should start from this bug tracker

I have a very simple dockerfile:

FROM ubuntu:16.04
RUN apt-get update && apt-get -y install redis-server
CMD service redis-server start && \ 
    redis-server --version && \
    tail -f /var/log/redis/redis-server.log

It's working fine in ubuntu 16.04:

$ docker run -it e1f
Starting redis-server: redis-server.
Redis server v=3.0.6 sha=00000000:0 malloc=jemalloc-3.6.0 bits=64 build=687a2a319020fa42

      `-._    `-.__.-'    _.-'                                       
          `-._        _.-'                                           
              `-.__.-'

20:M 22 Jun 09:31:04.781 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.

But if I change base image to ubuntu 18.04

FROM ubuntu:18.04
RUN apt-get update && apt-get -y install redis-server
CMD service redis-server start && \ 
    redis-server --version && \
    tail -f /var/log/redis/redis-server.log

I get:

$ docker run -it 87d
Starting redis-server: redis-server.

17:M 22 Jun 09:32:51.117 # Creating Server TCP listening socket ::1:6379: bind: Cannot assign requested address

and redis server fails to start

Found workaround - disable IPv6 for redis by
sed -i "s/bind .*/bind 127.0.0.1/g" /etc/redis/redis.conf

Dupe of #3894 I think.

Now fixed in Redis 5 and unstable. Just merged into 4.0 branch as well. Closing.
