How to setup Docker container with Redis (Stack) server to use a configuration file?

I need to run a Docker container with Redis Stack pre-configured to use a config file and ACL file. My Dockerfile (placed in the same folder as the redis.conf and users.acl) is as follows:

FROM redis/redis-stack:latest
WORKDIR /db
COPY redis.conf ./redis-stack.conf
COPY users.acl ./users.acl
ENV PORT=6379
EXPOSE 6379

I run the container with docker run -p 6379:6379 --mount type=volume,source=database-vol,target=/db,readonly=0 container_name, using a named volume.

After this, the Redis server starts, but instead of using these config/acl files, uses a default .conf, seemingly placed in the /opt/redis-stack/etc folder. Using COPY in the Dockerfile to place my files in that folder instead doesn’t help: the files are there, but the server doesn’t use them: redis-cli command acl list returns the default user only, meaning my .conf file is ignored.

I understand there is a possibility to pass arguments in docker run with --env REDIS_ARGS="", but I am not sure if/which arguments would setup the configuration file.

How do I point the redis server in the container to use my files? Is it possible for them to be in an arbitrary location?

    After some trying, figured it out. redis-stack-server (or redis-server if you're using the non-stack image) executable is already configured in PATH, so it's possible to CMD or RUN it easily from the Dockerfile.

    To run the server with the given config file, I use CMD [ "redis-stack-server", "redis.conf" ]. The full Dockerfile is then as follows:

    FROM redis/redis-stack:latest 

WORKDIR /usr/local/db

COPY redis.conf ./redis.conf
COPY users.acl ./users.acl

ENV PORT=6379
EXPOSE 6379

CMD [ "redis-stack-server", "redis.conf" ]

    This will start the Redis Stack server with the given configuration, as well users provided in the ACL file.

    Location of acl file is configured with aclfile parameter.

    So, based on your Dockerfile, adding --env REDIS_ARGS="envfile /db/users.acl" should do the trick.

    Somehow related, pass arguments via the command line
