Redis Service
=============
.. include:: example_header.inc
Very simple, no frills, redis service.
Open a docker container
-----------------------
.. code-block:: bash
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.
.. code-block:: bash
apt-get update
apt-get install redis-server
exit
Snapshot the installation
-------------------------
.. code-block:: bash
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.
.. code-block:: bash
sudo docker run -d -p 6379 <your username>/redis /usr/bin/redis-server
Test 1
++++++
Connect to the container with the redis-cli.
.. code-block:: bash
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.
.. code-block:: bash
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
