Task
Upload an OVF Package to Create a vApp Template
A vCloud API client that has access to an OVF package can use a standard workflow to upload the package
and create a vApp template.
The initial configuration of a vApp is established in the OVF package on which its source template is based.
In the vCloud API, vApp templates are based OVF 1.0, an open standard format. For more information
about OVF and how the vCloud API uses it, see “About OVF,” on page 89.
An OVF package includes several kinds of files.
An OVF descriptor
An XML file that contains metadata that describe a virtual machine or
collection of related virtual machines and the deployment environment they
require. By convention, this file has the suffix .ovf.
Virtual disk files
The descriptor lists these files and includes information about their format.
An optional certificate
You can use this file to certify the authenticity of the package.
An optional manifest
Contains a SHA-1 digest of each of the files in the package.
Upload Workflow
The upload workflow for OVF packages uses a combination of vCloud API requests and standard HTTP file
transfer requests.
1 The client makes a POST request to the catalog chosen to hold the template derived form the uploaded
OVF. The request body specifies a name, description, and other parameters used when creating the
template.
2 The server returns a CatalogItem that references a vApp template.
3 The client makes a GET request to the entity reference in the CatalogItem to retrieve the VAppTemplate,
which includes an upload URL for the OVF descriptor. Because the template is not yet complete, the
VAppTemplate element has status="0".
4 The client makes a PUT request to the upload URL and supplies the OVF descriptor in the request
body.
5 The server processes the descriptor and modifies the vAppTemplate to include an upload URL for each
file listed in the References section of the descriptor. While the server is modifying the vAppTemplate,
the client makes periodic requests for it and examines the response for additional upload URLs. When
the response contains additional upload URLs that were not present in the initial response, template
construction is complete.
6 The client uses PUT requests to upload each of the files.
