Understanding the Package Structure
Your .zpk package contains the data, scripts, and an XML descriptor file for your application.
74
Data - Your application (all the source code files of your application).
Descriptor File - This XML file, which is defined by an XSD file, describes all necessary
information in order to deploy your application using Zend Server’s deployment feature. For an
example of the descriptor template see The XML Descriptor File.
It contains three parts:
1. General information about the package:
name - (Required) The application's name.
summary - The application's short description.
description - The application's long description.
version - (Required) The application's version number.
eula - The EULA file.
appdir - (Required) The applications directory. By default, this is the data folder of
your package.
docroot - The alias will point to the directory you specify.
scriptsdir - The directory in which your scripts are located. By default, this is the
scripts folder of your package.
variables - Define environment variables for the deployment scripts.
2. Dependencies which need to be satisfied in order for the application to function correctly.
For example, PHP version and PHP directive values.
3. User parameters that are required for the application’s deployment. For example,
database name. These, along with the values you define, will appear in the User
Parameters dialog during deployment. For more information see Deploying an
Application.
• Scripts (PHP hook scripts) - Zend Serverdeployment consists of four actions: two for deployment,
and two for removal. Two hook scripts are provided for each action (pre and post), allowing you to
customize the actions according to your needs.
2. Deploy:
Stage - Place the contents of the .zpk application package on the server or on
the cluster nodes.
• Pre-stage - All customized actions that must be executed before the
staging process begins.
• Post-stage - All customized actions that must be executed after the
staging process ends.
Activate - Perform the final steps necessary to make a staged application public.
