Not able to start embedded redis in a docker container

[msarun]

Able to start in memory redis on my mac, when i run the same build inside a docker container to start my tests, the tests fail connecting to redis.

Might be a little late, but I had the same error and found the cause, so I thought I might as well add a comment here.
The issue seems to be, that the linux redis binaries shipped with the project were linked against glibc.
This means, that it is not working on Alpine Linux (which many containers run on), because they use another implementation of the C standard library.

Changing my base image from alpine to debian / ubuntu solved the issue for me.

It doesn't work alpine

It also seems this project is not maintained anymore, but musl-based binaries of Redis exist on Alpine:

~ % docker run -it --rm alpine
/ # apk add redis
fetch https://dl-cdn.alpinelinux.org/alpine/v3.13/main/x86_64/APKINDEX.tar.gz
fetch https://dl-cdn.alpinelinux.org/alpine/v3.13/community/x86_64/APKINDEX.tar.gz
(1/1) Installing redis (6.0.11-r0)
Executing redis-6.0.11-r0.pre-install
Executing redis-6.0.11-r0.post-install
Executing busybox-1.32.1-r6.trigger
OK: 8 MiB in 15 packages
/ # redis-
redis-benchmark  redis-check-aof  redis-check-rdb  redis-cli        redis-sentinel   redis-server

But embedded-redis probably doesn't detect whether the OS uses glibc or musl as its C standard library, and the included binary only works on glibc.

Another solution would be not use embedded-redis, but run Redis in a separate Docker container.
