Redis Service

Very simple, no frills, redis service.

Open a docker container

sudo docker run -i -t ubuntu /bin/bash

Building your image

Update your Docker container, install the Redis server. Once installed, exit out of the Docker container.

apt-get update
apt-get install redis-server
exit

Snapshot the installation

docker ps -a  # grab the container id (this will be the first one in the list)
docker commit <container_id> <your username>/redis

Run the service

Running the service with -d runs the container in detached mode, leaving the container running in the background. Use your snapshot.

sudo docker run -d -p 6379 <your username>/redis /usr/bin/redis-server

Test 1

Connect to the container with the redis-cli.

sudo docker ps  # grab the new container id
sudo docker inspect <container_id>    # grab the ipaddress of the container
redis-cli -h <ipaddress> -p 6379
redis 10.0.3.32:6379> set docker awesome
OK
redis 10.0.3.32:6379> get docker
"awesome"
redis 10.0.3.32:6379> exit

Test 2

Connect to the host os with the redis-cli.

sudo docker ps  # grab the new container id
sudo docker port <container_id> 6379  # grab the external port
ip addr show   # grab the host ip address
redis-cli -h <host ipaddress> -p <external port>
redis 192.168.0.1:49153> set docker awesome
OK
redis 192.168.0.1:49153> get docker
"awesome"
redis 192.168.0.1:49153> exit
