Controlling resource consumption using LimitRanges

This is another way of control resource allocation in OpenShift at the project level, but unlike ResourceQuotas, they are different in certain ways:

• They are applied to individual pods, containers, images, or image streams
• They don't control some resources such as secrets, ConfigMaps, ResourceQuotas, services, and ReplicationControllers
• They can be created from a raw definition only

Depending on the type of resource they are applied to, LimitRanges control various computing resources and objects:

Resource type	Computing resources/attributes controlled
Pod	CPU RAM
Container	CPU RAM
Image	Size of an image pushed into an internal registry
ImageStream	Number of unique image tags as per image stream's spec Number of unique image references as per the image stream's status
PersistentVolumeClaim...
