Setting redis configuration with docker in windows

Question

I want to set up redis configuration in docker.

I have my own redis.conf under D:/redis/redis.conf and have configured it to have bind 127.0.0.1 and have uncommented requirepass foobared

Then used this command to load this configuration in docker:

docker run --volume D:/redis/redis.conf:/usr/local/etc/redis/redis.conf --name myredis redis redis-server /usr/local/etc/redis/redis.conf

Next, I have docker-compose.yml in my application in maven Project under src/resources.

I have the following in my docker-compase.yml

redis:
 image: redis
 ports:
   - "6379:6379"

And i execute the command :

docker-compose up

The Server runs, but when i check with the command:

docker ps -a

it Shows that redis Image runs at 0.0.0.0:6379.

I want it to run at 127.0.0.1.

How do i get that? isn't my configuration file loading or is it wrong? or my commands are wrong?

Any suggestions are of great help.

PS: I am using Windows.

Thanks

Try to execute:

docker inspect <container_id>

And use "NetworkSettings"->"Gateway" (it must be 172.17.0.1) value instead of 127.0.0.1.

You can't use 127.0.0.1 as your Redis was run in the isolated environment.

Or you can link your containers.

Thanks for ur Reply @Aleksandr Yes it Shows 172.17.0.1. And i changed the bind at redis.conf to bind 172.17.0.1. But again when i do execute the command docker run --volume D:/redis/redis.conf:/usr/local/etc/redis/redis.conf --name myredis redis redis-server /usr/local/etc/redis/redis.conf and execute the command docker-compose up it Shows the same

So first of all you should not be worried about redis saying listening on 0.0.0.0:6379. Because redis is running inside the container. And if it doesn't listen on 0.0.0.0 then you won't be able to make any connections.

Next if you want redis to only listen on localhost on localhost then you need to use below

redis:
 image: redis
 ports:
   - "127.0.0.1:6379:6379"

PS: I have not run container or docker for windows with 127.0.0.1 port mapping, so you will have to see if it works. Because host networking in Windows, Mac and Linux are different and may not work this way

i just noticed that whenever i Change the bind or uncomment the requirepass, then i get that Connection refused, incase i Keep the ip to 127.0.0.1 or the Gateway and give Password as null in my redis.yml then it works. SO i think my redis.conf isnt loading properly though it Shows configuration loaded

Assuming you are using Docker for Windows, is your D: shared in Docker settings with the Docker VM?

yes i can see my drive being shared in docker settings

The redis bind should always be 0.0.0.0 in config. Also run docker-compose exec redis cat /usr/local/etc/redis/redis.conf to make sure the config you passed is inside the container
