Unable to connect to dockerized redis instance from outside docker - redis

Question

I have the latest docker installation (without boot2docker) and I am unable to connect to a dockerized redis instance running locally. Could you please tell me what I'm doing wrong here?
Created the docker, mapped port 6379 to 127.0.0.1:6379
bash-3.2$ docker run -p 127.0.0.1:6379:6379 --name webmonitor-redis -d redis
3291541d58ab16c362f9e0cd7017d179c0bc9aef3a1323e79f1e1ca075e171c9
docker ps output:
bash-3.2$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3291541d58ab redis "/entrypoint.sh redis" 14 seconds ago Up 6 seconds 127.0.0.1:6379->6379/tcp webmonitor-redis
Tried connecting from outside container (but the same host where container is running), connection failed:
bash-3.2$ ./src/redis-cli
Could not connect to Redis at 127.0.0.1:6379: Connection refused
not connected> exit
It works if I try to connect from another container though..
bash-3.2$ docker run -it --link webmonitor-redis:redis --rm redis sh -c 'exec redis-cli -h "$REDIS_PORT_6379_TCP_ADDR" -p "$REDIS_PORT_6379_TCP_PORT"'
172.17.0.8:6379>
Here's the docker inspect for the container:
bash-3.2$ docker inspect 3291541d58ab

Am I missing something here?

Answer 1

make sure the port 6379 on the host is forwarded to port 6379 on docker.
use -p 6379:6379 to fixed the problem:
docker run -d --name redisDev -p 6379:6379 redis

Answer 2

The VM has it's own IP 192.168.99.100 so I was able to connect by binding to 192.168.99.100:6379:6379 and then connecting as below.
0c4de9a25467:redis-stable electron$ ./src/redis-cli -h 192.168.99.100
192.168.99.100:6379>

Answer 3

docker run -p 6379:6379 -host 0.0.0.0 --name webmonitor-redis -d redis
