Advanced Tasks Creating Customized Containers If you wish to run one or several customized applications inside your Containers and the number of such Containers is relatively large, you may think of a way to automate the process of creating Containers that already have a number of applications installed and tuned to meet your demands. So, you do not need to manually install and customize your applications every time you create a new Container. Parallels Server Bare Metal allows you to create customized Containers having a certain set of customized applications installed inside them right after their creation in one of the following ways: • By making a customized base OS EZ template and using it as the basis for Containers. • By making a non-base OS EZ template and using it as the basis for Containers. • By making a customized application EZ template, adding it to a new configuration sample file, and using this sample file as the basis for Containers. All these operations are described in the following subsections in detail. 220
Using Customized OS EZ Templates Advanced Tasks Let us first start with making a customized base OS EZ template which can then be used to create Containers with a set of application already tuned to meet your demands. To make such a template, do the following: 1 Create a metafile that will serve as the basis for your customized base OS EZ template. Notes: 1. Detailed information on how to create metafiles is given in the Parallels Server 5 Bare MetalTemplates Management Guide. 2. While creating a metafile for a new OS EZ template, make sure that the value of either the %osname parameter or the %version parameter in the metafile differs from the names or versions of all base OS EZ templates installed on the server. 2 Create one or more scripts that will be executed on different stages of the OS EZ template lifecycle and customize your applications to meet your needs. For example, you can create a postinstall script with the name of post_install.bash and make it perform a number of customization operations on some application included in the OS EZ template after installing this application inside your Container. 3 Create a customized OS EZ template by running the vzmktmpl utility and passing the corresponding options to it. So, you can use the --post-install option and specify the path to the post_install.bash script from the example above to make an OS EZ template that will customize your application after installing it inside your Container. Note: The full list of options allowing you to specify what scripts are to be executed on what stage of the EZ template lifecycle is provided in the vzmktmpl subsection of the Parallels Containers 4.6 Line Reference Guide. 4 Install the customized OS EZ template on the server using the rpm -i command. 5 Cache the created OS EZ template by running the vzpkg create cache command. Detailed information on how you can do it is provided in the Parallels Server 5 Bare Metal Templates Management Guide. 6 Create a Container based on the OS EZ template. For example, to create a Container that will run CentOS 5 and have the customized mysql and apache applications installed right after its creation, you can do the following: 1 Create a metafile for the Cent OS EZ template, name it, for example, centos_5_customized.metafile, and save in the /root/centos_5 directory on the server. 2 Make a script that will perform a number of custom operations after applying the mysql and apache application EZ templates to the Container, and name it post_install.bash. 3 Copy the script to the /root/centos_5 directory on the server. 4 Execute the following command on the server to create the CentOS 5 OS EZ template: 221
