Appliance Kit › Appliance Cookbook › Creating a VDS Template

Creating a VDS Template

This recipe builds on the Blank Appliance one, and adds the following customizations, appropriate for using the appliance as a general purpose virtual server:

• An internet-accessible network interface.
• Secondary SSH login with its own configuration file and access key setup, independent of the automatic setup performed by APK for the benefit of the ssh command of the CA 3Tera AppLogic shell.
• Configuration properties to facilitate the use of the VDS appliance class for easy provisioning (That is simple/automated making of copies of the VDS to rent out to clients).

The first step is to create the OS image for the future VDS template. The Blank Appliance recipe described above can be used, or one can start from an existing blank appliance class. Here is what needs to be set up differently:

• Larger disk volume, with more software pre-installed
• The appliance class will not become a catalog class, instead the entire application containing the VDS component is saved as a template.
• The root password is set to empty before saving the application as a template - this is used as an indication to the startup script to initialize the password (see VDS Server Configuration for more on root password configuration).
• The external interface is enabled in the component descriptor (Edit Class, Interfaces, External interface).
