Simple Kubernetes Blueprint

This blueprint deploys a simple Kubernetes cluster.

prerequisites

You will need a Cloudify Manager running in either AWS, Azure, or Openstack.

If you have not already, set up the example Cloudify environment. Installing that blueprint and following all of the configuration instructions will ensure you have all of the prerequisites, including keys, plugins, and secrets.

Step 1: Install the demo application

In this step, you will first gather two pieces of information from your Cloud account: the parameters of a Centos 7.0 image and a medium sized image. This info is already provided for AWS us-east-1 and Azure us-east.

Next you provide those inputs to the blueprint and execute install:

For AWS run:

$ cfy install \
    https://github.com/cloudify-examples/simple-kubernetes-blueprint/archive/4.0.1.zip \
    -b demo \
    -n aws-blueprint.yaml

For Azure run:

$ cfy install \
    https://github.com/cloudify-examples/simple-kubernetes-blueprint/archive/4.0.1.zip \
    -b demo \
    -n azure-blueprint.yaml

For Openstack run:

$ cfy install \
    https://github.com/cloudify-examples/simple-kubernetes-blueprint/archive/4.0.1.zip \
    -b demo \
    -n openstack-blueprint.yaml -i flavor=[MEDIUM_SIZED_FLAVOR] -i image=[CENTOS_7_IMAGE_ID]

You should see something like this when you execute the command:

$ cfy install \
    https://github.com/cloudify-examples/simple-kubernetes-blueprint/archive/4.0.1.zip \
    -b demo \
    -n aws-blueprint.yaml

Step 2: Verify the demo installed and started.

Once the workflow execution is complete, get your configuration file contents from your Kubernetes master:
