Quotas and Accounting

Quotas

Each project is assigned a quota which defines how much resources that a project can use. When resource consuming operations such as virtual machine creation are performed, the request is validated against the maximum quota permitted for the current project (as set by the environment variables or Horizon dashboard).

For shared projects, you can request additional resources via change project quota.

The project quota can be checked using:

gigabytes_type Total space in the volume storage class type such as standard
injected-file-size Number of content bytes allowed per injected file.
injected-path-size Number of bytes allowed per injected file path.
injected-files Number of injected files allowed per project.
instances Number of virtual machines allowed per project.
key-pairs Number of key pairs allowed per user.
ram Total megabytes of instance ram allowed per project.
security-groups Number of security groups per project.
security-group-rules Number of rules per security group.
snapshots Total number of volume snapshots allowed per project
snapshots_type Snapshots allowed for the volume storage class type
volumes Total volumes allowed for the project
