Now that we have a good understanding of how to make our module stateless, let's go ahead and start coding. We will split the coding into two parts. In the first part we will write the module to install and configure Docker UCP. The final topic will be to run Kubernetes as the frontend.
The first thing that we need to do is create a new Vagrant repo for this chapter. By now, we should be masters at creating a new Vagrant repo. Once we have created that, we will create a new module called <AUTHOR>-ucpconfig
and move it to our modules
directory in the root of our Vagrant repo. We will first set up our servers.yml
file by adding the code shown in the following screenshot:
As you can see, we are setting up three servers, where ucp-01
will be the master of the cluster and the other two nodes will join the cluster. We will add two more files: config.json
and docker_subscription.lic
. Here, config.json
will contain the authorization key to Docker Hub, and docker_subscription.lic
