The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

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 provides access to features for managing cartridges on devices.
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.
The Cartridges page, which displays when you choose the CARTRIDGES tab in Cisco Fog Manager, provides general information about cartridges that have uploaded to Cisco Fog Manager, and lets you import additional cartridges.
