7.2

You set property bindings when you configure components in a blueprint. On the Blueprint page, you drag
your component onto the canvas and click the Properties tab. To bind a property to another property in a
blueprint, select the Bind checkbox. You can enter ComponentName~PropertyName in the value text
box, or you can use the down arrow to generate a list of available binding options. You use a tilde
character ~ as a delimiter between components and properties. For example, to bind to the property
dp_port, on your MySQL software component, you could type mysql~db_port. To bind to properties that
are configured during provisioning, such as the IP address of a machine or the host name of a Software
component, you enter _resource~ComponentName~PropertyName. For example, to bind to the
reservation name of a machine, you might enter
_resource~vSphere_Machine_1~MachineReservationName.

Creating Explicit Dependencies and Controlling the Order of
Provisioning
If you need information from one of your blueprint components to complete the provisioning of another
component, you can draw an explicit dependency on the design canvas to stagger provisioning so the
dependent component is not provisioned prematurely. Explicit dependencies control the build order of a
deployment and always trigger dependent updates during a scale in or scale out operation.
When you design blueprints with multiple machines and applications, you might have properties you need
from one machine to finish an application installation on another. For example, if you are building a Web
server you might need the host name of the database server before you can install the application and
instantiate database tables. If you map an explicit dependency, your database server starts provisioning
when your Web server finishes provisioning.
