Managing Cartridges

Packages for PAAS apps include only the app logic (such as Python or Java files), but not the Linux operating files or the root file system that the app requires. Cartridges provide the root file system and Python or Java files that an app requires to run.

Before you can install a PAAS through Cisco Fog Director, you must add the cartridges that the app requires. Cisco Fog Director prevents installing a PAAS app that requires cartridges if the cartridges have not been added.

Cartridges are not used by KVM apps.

The Cisco Fog Director Cartridges page provides information about cartridges and lets you manually add a cartridge to Cisco Fog Director.

To access the Cartridges page, log in to Cisco Fog Director as described in the “Accessing Cisco Fog Director” section, and then click the CARTRIDGES tab. The Devices View page displays.

This chapter includes these sections:
