FATAL CONFIG FILE ERROR using default redis.conf

[tayl]

Hello,

I'm running into the following issue when following the steps at https://hub.docker.com/_/redis/

*** FATAL CONFIG FILE ERROR ***
Reading the configuration file, at line 335
>>> 'rdb-del-sync-files no'
Bad directive or wrong number of arguments

if I comment out that entry, I get

*** FATAL CONFIG FILE ERROR ***
Reading the configuration file, at line 484
>>> 'repl-diskless-load disabled'
Bad directive or wrong number of arguments

My Dockerfile is taken from the Redis Docker Hub as follows

FROM redis
COPY redis.conf /usr/local/etc/redis/redis.conf
CMD [ "redis-server", "/usr/local/etc/redis/redis.conf" ]

and my redis.conf is taken from http://download.redis.io/redis-stable/redis.conf

I thought it might be a file encoding error, so I downloaded the exact bytes from the above URL but still faced this issue. Also tried redis:buster but had the same issues. The issue happens while using Docker desktop, as well as in our deployed AWS Fargate environment.

Of course, minutes after I post this I realize the issue. Redis Docker stable is 5, Redis.io stable is 6. The redis.io redis.conf file is incompatible with Stable Redis Docker.

Heh, Redis 6 only went GA today, and merged in docker-library/official-images#7914 minutes ago, so please hold out just a tiny bit longer while it builds! 😅
