NetworkConfiguration Schema

Updated: April 3, 2014

The NetworkConfiguration element of the service configuration file specifies Virtual Network and DNS values. These settings are optional for cloud services.

You can use the following resource to learn more about Virtual Networks and the associated schemas:

The following example shows the NetworkConfiguration element and its child elements.


<ServiceConfiguration>
  <NetworkConfiguration>
    <AccessControls>
      <AccessControl name="aclName1">
        <Rule order="<rule-order>" action="<rule-action>" remoteSubnet="<subnet-address>" description="rule-description"/>
      </AccessControl>
    </AccessControls>
    <EndpointAcls>
      <EndpointAcl role="<role-name>" endpoint="<endpoint-name>" accessControl="<acl-name>"/>
    </EndpointAcls>
    <Dns>
      <DnsServers>
        <DnsServer name="<server-name>" IPAddress="<server-address>" />
      </DnsServers>
    </Dns>
    <VirtualNetworkSite name="<site-name>"/>
    <AddressAssignments>
      <InstanceAddress roleName="<role-name>">
        <Subnets>
          <Subnet name="<subnet-name>"/>
        </Subnets>
      </InstanceAddress>
    </AddressAssignments>
  </NetworkConfiguration>
</ServiceConfiguration>

The following table describes the child elements of the NetworkConfiguration element.

 

Element Description

AccessControl

Optional. Specifies the rules for access to endpoints in a cloud service. The access control name is defined by a string for name attribute. The AccessControl element contains one or more Rule elements. More than one AccessControl element can be defined.

Rule

Optional. Specifies the action that should be taken for a specified subnet range of IP addresses. The order of the rule is defined by a string value for the order attribute. The lower the rule number the higher the priority. For example, rules could be specified with order numbers of 100, 200, and 300. The rule with the order number of 100 takes precedence over the rule that has an order of 200.

The action for the rule is defined by a string for the action attribute. Possible values are:

  • permit – Specifies that only packets from the specified subnet range can communicate with the endpoint.

  • deny – Specifies that access is denied to the endpoints in the specified subnet range.

The subnet range of IP addresses that are affected by the rule are defined by a string for the remoteSubnet attribute. The description for the rule is defined by a string for the description attribute.

EndpointAcl

Optional. Specifies the assignment of access control rules to an endpoint. The name of the role that contains the endpoint is defined by a string for the role attribute. The name of the endpoint is defined by a string for the endpoint attribute. The name of the set of AccessControl rules that should be applied to the endpoint are defined in a string for the accessControl attribute. More than one EndpointAcl elements can be defined.

DnsServer

Optional. Specifies the settings for a DNS server. You can specify settings for DNS servers without a Virtual Network. The name of the DNS server is defined by a string for the name attribute. The IP address of the DNS server is defined by a string for the IPAddress attribute. The IP address must be a valid IPv4 address.

VirtualNetworkSite

Optional. Specifies the name of the Virtual Network site in which you want deploy your cloud service. This setting does not create a Virtual Network Site. It references a site that has been previously defined in the network file for your Virtual Network. A cloud service can only be a member of one Virtual Network. If you do not specify this setting, the cloud service will not be deployed to a Virtual Network. The name of the Virtual Network site is defined by a string for the name attribute.

InstanceAddress

Optional. Specifies the association of a role to a subnet or set of subnets in the Virtual Network. When you associate a role name to an instance address, you can specify the subnets to which you want this role to be associated. The InstanceAddress contains a Subnets element. The name of the role that is associated with the subnet or subnets is defined by a string for the roleName attribute.

Subnet

Optional. Specifies the subnet that corresponds to the subnet name in the network configuration file. The name of the subnet is defined by a string for the name attribute.
