Cartridges are the parts of an OPENSHIFT Enterprise application that include the application code NEEDED to run it. Programming languages, databases, monitoring services, and management are all supported by cartridges.

Adding a cartridge to an application gives you the functionality you want without having to manage or maintain the incorporated feature. When a cartridge is added to an application, it is assigned to ONE or more gears based on its specifications. Other cartridges can be deployed across several gears of an application, whereas those that listen to incoming traffic are placed on one or more gears.

WEB cartridges are available for a variety of programming languages and frameworks, and every application needs at least one to listen for HTTP requests. When creating an application, the type of web framework cartridge must be selected. Other cartridges can be deployed across several gears of an application, whereas those that listen to incoming traffic are placed on one or more gears.

Following the creation of an application with the essential web framework cartridge, a variety of add-on cartridges, such as databases, scheduled jobs, and continuous integration, can be used to enhance the functionality and CAPABILITIES of the programme. Database Cartridges and Monitoring and Management Cartridges are other types of cartridges available.

Along with the supported standard OpenShift Enterprise cartridges, downloadable cartridges are available for new and existing applications. These are user-created cartridges or cartridges accessible from the OpenShift community. The URL to the manifest of the hosted downloadable cartridge is used to download and install these cartridges.
