13.3.2. Cartridge-Version

The Cartridge-Version element identifies the release version of a cartridge. The value uses the format:

<number>[.<number>[.<number>[...]]]

For example:

Cartridge-Version: '1.0.3'

When you publish a new version of a cartridge, OpenShift Enterprise uses the Cartridge-Version value to determine upgrade requirements for applications that use the cartridge. YAML treats number.number as a float but OpenShift Enterprise requires a string for this value, so the value must be enclosed in single quotes (').
