Installing Wrapper Packages from External Repositories

This chapter describes the installation of wrapper packages from external repositories using software delivery functionality in detail.

Sample DSM Architecture with External Debian Repositories

Forward Inc is a mid-sized banking organization that deployed CA ITCM to manage its physical and virtual infrastructure. Forward Inc is headquartered in New York and has branch offices in US and India. Each country has a data center and has several branch offices.

The current CA ITCM implementation looks like the following:

• The DSM enterprise manager is located in the headquarters.
• A DSM domain manager is located in the data center of each country.
• A scalability server is located in major cities serving various neighboring branches.

Forward Inc has a few thousand computers that are on Debian OS and requires the ability to deploy Debian software packages from CA ITCM. The master Debian repository is located in the headquarters. The company wants to create and deploy wrapper packages on each domain manager so that deployment is faster. Here is how they do it:

• Added the external Debian repository as the master repository to the enterprise manager
• Created a mirror of the master Debian repository in each data center
• Associated the mirrors in each data center as the master repository to the respective domain managers so that wrapper packages can be created from the mirror on the data center. Wrapper packages that are applicable to the entire organization is created at the enterprise manager and distributed to the domain managers.
• Created mirrors on the scalability servers from the mirror on the data center, by configuring the respective domain managers

The following architecture diagram illustrates the DSM Architecture with the Debian repositories and mirrors:

How to Deploy Packages from External Debian Repositories

The following process describes how you configure CA ITCM to deploy packages from Debian repositories:

1. Add the external Debian repository details in CA ITCM
2. Set up mirror repositories
3. Set up HTTP and FTP shares on repository servers
4. Deploy Debian packages using software delivery
