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
|
|
|
|
sudo docker ps -a # grab the container id (this will be the first one in the list)
|
|
sudo 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`` binary.
|
|
|
|
.. 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`` binary.
|
|
|
|
.. 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
|
