HAProxy Blueprint

This blueprint deploys an HAProxy Load Balancer. This blueprint is part of the End-to-end Solutions Package, which demonstrates functionality in Cloudify using a Database, Load Balancer, and several front-end applications. Before installing this deployment, install the MariaDB Blueprint, then continue with the solution package by installing the Drupal Blueprint.

Compatibility

Tested with:

  • Cloudify 4.3.1

Pre-installation steps

Please note the following requirement for manager configuration.

This example requires configuration of multiple management (agent) networks upon installation of your Cloudify Manager.

The required name of the agent network is external, and should map to a public IP address. For example:

[centos@ip-10-10-4-47 ~]$ sudo grep "networks" /etc/cloudify/config.yaml 
    networks: {default: 10.10.4.47, external: 54.67.45.103}

Upload the required plugins:

Check the relevant blueprint for the latest version of the plugin.

Install the relevant example network blueprint for the IaaS that you wish to deploy on:

In addition to the pre-requisites for your example network blueprint, you will need the following secrets:

  • agent_key_private and agent_key_public. If you do not already have these secrets, can generate them with the keys.yaml blueprint in the helpful blueprint repo.

Install the MariaDB Blueprint

  • After installation is successful, check the deployment outputs. There is a single deployment output called cluster_addresses, which is a list of IP addresses. Select a single IP, this will be the value for your application_ip input in this blueprint, as a seed-IP.

Installation

On your Cloudify Manager, navigate to Local Blueprints select Upload.

Right-click and copy URL. Paste the URL where it says Enter blueprint url. Provide a blueprint name, such as lb in the field labeled blueprint name.

Select the blueprint for the relevant IaaS you wish to deploy on, for example aws.yaml from Blueprint filename menu. Click Upload.

After the new blueprint has been created, provide the seed application_ip input (see Install the MariaDB Blueprint above) click the Deploy button.

Navigate to Deployments, find your new deployment, select Install from the _workflow_s menu. At this stage, you may provide your own values for any of the default deployment inputs.

For example, the openstack.yaml blueprint requires that you provide a value for image. This is the ID of a Centos 7 image. You may also need to override the default flavor as the default value 2 may not be available in your account or appropriate.

Uninstallation

Navigate to the deployment and select Uninstall. When the uninstall workflow is finished, select Delete deployment.
