Calling redis-cli in docker-compose setup

Question

I run the official Redis image https://hub.docker.com/_/redis/ in a docker-compose setup.

myredis:   image: redis 

How can run redis-cli with docker-compose on that image?
I tried the following, but it didn't connect:

docker-compose run myredis redis-cli > Could not connect to Redis at 127.0.0.1:6379: Connection refuse 

The docs of the image says that I should run:

docker run -it --rm \ --link some-redis:redis \ redis \ sh -c 'exec redis-cli -h "$REDIS_PORT_6379_TCP_ADDR" -p "$REDIS_PORT_6379_TCP_PORT"' 

How does this translate to docker-compose run?

Answer 1

That would override the default CMD [ "redis-server" ]: you are trying to run redis-cli on a container where the redis-server was never executed.

As mentioned here, you can also test with:

docker exec -it myredis redis-cli 

From docker-compose, as mentioned in this docker/compose issue 2123:

rcli:   image: redis:latest   links:     - redis   command: >      sh -c 'redis-cli -h redis ' 

This should also works:

rcli:   image: redis:latest   links:     - redis   command: redis-cli -h redis 

As the OP ivoba confirms (in the comments), the last form works.
Then:

docker-compose run rcli 

ivoba also adds:

docker-compose run redis redis-cli -h redis works also when the containers are running.
This way its not necessary to declare a separate rcli container.

Answer 2

You can also use this command:

docker-compose run myredis redis-cli -h myredis
