The vCloud plugin enables you to use a vCloud-based infrastructure for deploying services and applications.

Plugin Requirements

  • Python version 2.7.x

vCloud Configuration

The vCloud plugin requires credentials in order to authenticate and interact with vCloud.

The information is gathered by the plugin from the following sources. Each source might partially or completely override values gathered from the previous ones.

  • JSON file at ~/vcloud_config.json or at a path specified by the value of an environment variable named VCLOUD_CONFIG_PATH.
  • Values specified in the vcloud_config property for the node thats operation is currently being executed. (In the case of relationship operations, the vcloud_config property of either the source or target nodes are used if available, with the source node’s property taking precedence).

The structure of the JSON file in the first bullet, and of the vcloud_config property in the second bullet, is as follows:

  
{
    "username": "",
    "password": "",
    "url": "",
    "org": "",
    "vdc": "",
    "service": "",
    "service_type": "",
    "api_version": "",
    "instance": "",
    "org_url": "",
    "ssl_verify": ""
}

  • username - The vCloud account username.
  • password - The vCloud account password.
  • url - The vCloud URL.
  • org - The organization name. Required only for the ondemand and subscription service types.
  • instance - The instance UUID. Required only for the ondemand service type.
  • vdc - The virtual datacenter name.
  • service - The vCloud service name.
  • service_type - The service type. Can be subscription, ondemand, vcd or private. Private is an alias for vcd and both types can be used with a private vCloud environment without any difference. Defaults to subscription.
  • api_version - The vCloud API version. For Subscription, defaults to 5.6. For OnDemand, defaults to 5.7.
  • region - The region name. Applies to OnDemand.
  • org_url - The organization URL. Required only for private service type.
  • edge_gateway - The Edge gateway name.
  • ssl_verify A boolean flag for disabling the SSL certificate check. Only applicable for a private cloud service with self-signed certificates. Defaults to True

Tip

The vCloud Manager blueprint stores the vCloud configuration used for the bootstrap process in a JSON file (as described in the first bullet of this section) at ~/vcloud_config.json. Therefore, if they have been used for bootstrapping, the vCloud configuration for applications is not mandatory, because the plugin defaults to these same settings.

Misc

vApp template

The template requires a VM with root disk with OS, SSH server and VMware Tools installed.

The template must not have any networks connected.

Types

Tip

Each type has a vcloud_config property. It can be used to pass parameters for authentication. You do not need to override this property and, by default, the authentication uses the same credentials that were used for the Cloudify bootstrap process.
