Loading module during build is not working on Apple M1

[bridge-jithesh]

Below is my Dockerfile:

FROM redis
ARG MASTER_AUTH
COPY redis.conf /usr/local/etc/redis/redis.conf
RUN mkdir -p /usr/local/etc/redis/modules
COPY ./modules /usr/local/etc/redis/modules
RUN chmod +x /usr/local/etc/redis/modules/librejson.so
RUN chmod +x /usr/local/etc/redis/modules/redisearch.so
CMD [ "redis-server", "/usr/local/etc/redis/redis.conf" ]

as you can see I am copying all my modules into the container during the build. But I am getting the below error when trying to start the container.

Now the reason I put Apple M1 on the title is that the same Dockerfile is working fine on all other platforms. I've tested it with Ubuntu 20 LTS, WSL2 on Windows. Works absolutely fine. I have the error only on my Apple M1.

How I should debug this?

This sounds like your modules are compiled for amd64, but for the M1 they need to be arm64v8 (or you need to run with amd64 emulation enabled instead, which will be slower).

Closing since this seems resolved, if you need further help you could also try asking over at the Docker Community Forums, Docker Community Slack, or Stack Overflow
