Docker Cloud; you can deal with different Cloud Providers through a single API! (part1)


Hi again!

How Docker is good, is attractive, is … splendid. Just after the Docker Datacenter, Docker Cloud is the new solution to create cluster nodes on different platforms like Azure, containers and Stacks (in Swarm fashion).

Ok today I will show you some steps for two scenarios on Azure:

  1. A simple Web application hosted in a single container (part1).
  2. A 3 tiers application (part 2) based on:
    1. Haproxy as a load balancer and reverse proxy hosted on a single container
    2. 4 Web applications hosted on 4 containers
    3. Redis server hosted on a single container to provide cache capabilities

Let us start with the firts scenario:

  1. First of all, you import a certificate into the settings of your Azure account to authenticate the Docker Cloud API.
  2. You create a cluster of a given number of nodes. You can resize your cluster. However according to Docker Cloud, the first node is free!!!! Yes. You have just to select the template of your service cloud.

  1. After that, you will notice that a service cloud and the corresponding virtual machine are created.

  1. Ok, now you will create a container that will host the Web Server and the application.

  1. You select the appropriate image. In my case I choose dockercloud/hello-world image. Here you will notice that you can select a deployment strategy when using a cluster of nodes. You can instanciate a given number of the containers from the same image. You can also define a stack file that draws the composed architecture.

  1. On the Ports section you have to publish the default port. In my case I define the default http port. But don’t forget to define an endpoint listening on this port for the virtual machine hosting the containers host.

  1. Now the service is created, we have just to start it.
