Set org, space, and app limits

Table of Contents

Org Managers are free to configure your org’s quota capacity among your spaces and applications as you see fit. This enables Org Managers to limit usage and corresponding costs.

Org

See more about how to manage your orgs’ quotas.

Space

Org Managers can create and modify space quota plans to limit the resources used by spaces. See the CF CLI documentation for create-space-quota to create the quota plan, and create a space with that quota plan using create-space (which has the option [-q SPACE_QUOTA]).

App

Space Developers can specify application limits in your application manifest or as cf push command line options.

Application limit options

memory: / -m

• Default: 1GB
• Minimum: Based on the app's usage and runtime requirements
• Maximum: Based on organization's quota and its provisioned apps

The application memory limit. This setting has a dual-purpose, as your application compute limit is derived from its memory limit. This relationship is explained in detail here.

disk_quota / -k

• Default: 1GB
• Minimum: Based on the app's source and dependencies disk size
• Maximum: 7GB

The maximum amount of disk space available to your app.

instances: / -i

• Default: 1
• Minimum: 0
• Maximum: Based on organization's quota and its provisioned apps

Sets the number of application instances to launch. Each additional instance receives the same memory and disk reservation. An application with a manifest specifying memory: 256M and instances: 4 would reserve 1GB (256M x 4) total.

Limited:

The application cannot access more than the specified amount of memory.

Application limit options: sizing

• The environment default of 512MB memory: is sufficient for most applications. Static sites and utility applications such as schedulers or loaders may require less. Use cf app APPNAME to check your application’s current memory and compute utilization.

• Any application which exceeds its memory limit will be automatically restarted. Use cf events APPNAME to look for ‘out of memory’ crashes.
