Agents

The Cloudify Agent is a component that is installed on hosts that are part of your blueprint. The Cloudify Agent communicates with the Cloudify Manager.

The Agent execute orchestration operations locally, and collects metrics and report them to the Cloudify Manager.

If your blueprint does not require these functions, you can exclude the agent installation from the Cloudify Manager installation process.

Agent Packages

Cloudify Agent is supported over the following platforms:

• RHEL / CentOS 7.x (Python 3.6)
• RHEL / CentOS 8.x (Python 3.6)
• Ubuntu 16.x / 18.x (Python 3.6)
• Windows 2012 and later (Python 2.7)

In addition, you can use the Cloudify Agent Packager in case you need an agent package for other Linux platforms.

Notes:

• For Linux platforms, you must have Python installed on the image at the time of the agent installation.
  • If your image does not include Python, you can use initialization scripts supported by Cloudify (userdata on OpenStack, Customization Scripts on AWS etc.) to install Python.
• For Windows, the agent installer is bundled with a Python interpreter.

Communication with the manager

The agent requires access to the manager with these services:

1. TCP Port 53333 (REST API; HTTPS)
2. TCP Port 53229 (file server; HTTPS)
3. TCP Port 5671 (RabbitMQ; AMQP over TLS)

By default, the Cloudify Agent connects to the private IP of the Cloudify Manager as specified in the Manager installation. You can change the ports used by these services if necessary, such as in a multi-cloud environment.
