⁠10.6.1. Networks Sub-Collection

Networks associated with a cluster are represented with the networks sub-collection. Every host within a cluster connects to these associated networks.
The representation of a cluster's network sub-collection is the same as a standard network resource except for the following additional elements:
⁠

Table 10.4. Additional network elements

Element Type Description Properties
cluster id= relationship A reference to the cluster of which this network is a member.
required Boolean Defines required or optional network status.  
display Boolean Defines the display network status. Used for backward compatibility.  
usages complex Defines a set of usage elements for the network. Users can define networks as VM and DISPLAY networks at this level.  
An API user manipulates the networks sub-collection with the standard REST methods. POSTing a network id or name reference to the networks sub-collection associates the network with the cluster.

Example 10.5. Associating a network resource with a cluster

Update the resource with a PUT request.
⁠

Example 10.6. Setting the display network status

PUT /api/clusters/99408929-82cf-4dc7-a532-9d998063fa95/networks/da05ac09-00be-45a1-b0b5-4a6a2438665f HTTP/1.1

    <required>false</required>
    <usages>
        <usage>VM</usage>
        <usage>DISPLAY</usage>
    </usages>
</network>
The required or optional network status is set using a PUT request to specify the Boolean value (true or false) of the required element.
⁠

Example 10.7. Setting optional network status

PUT /api/clusters/99408929-82cf-4dc7-a532-9d998063fa95/networks/da05ac09-00be-45a1-b0b5-4a6a2438665f HTTP/1.1

Content-Type: application/xml

<network>
    <required>false</required>
</network>
An association is removed with a DELETE request to the appropriate element in the collection.
⁠

Example 10.8. Removing a network association from a cluster

DELETE /api/clusters/99408929-82cf-4dc7-a532-9d998063fa95/networks/da05ac09-00be-45a1-b0b5-4a6a2438665f HTTP/1.1
