Connecting to Redis running in Docker Container from Host machine

Question

I see lots of people struggling with this, sort of feel like maybe there is a bug in the redis container image, and others seem to be chasing a similar problem.

The problem is with your bind, You should set the following:

bind 0.0.0.0

This will set redis to bind to all interfaces available, in a containerized environment with one interface, (eth0) and a loopback (lo) redis will bind to both of the above. You should consider adding security measures via other directives in config file or using external tools like firewalls. because with this approach everyone can connect to your redis server.

The default setting is bind 127.0.0.1 and this setting will cause redis to only listen on loopback interface, and it will be only accessible from inside the container. (for security)

To run redis with custom configuration file:

sudo docker run -d --name redis-test -p 6379:6379  -v /path/to/redisconf/redis.conf:/redis.conf redis redis-server /redis.conf

Now to verify on docker host with redis-tools installed:

redis-cli                           
127.0.0.1:6379> 
127.0.0.1:6379> set farhad likes:stackoverflow
OK
127.0.0.1:6379> get farhad
"likes:stackoverflow"
127.0.0.1:6379> 

You can also connnect to your redis container from an external host via:

redis-cli -h 'IP-address-of-dockerhost-running-redis-container'
