Quotas Management

Quotas limit how many resources a project can consume in Safespring Compute. They prevent any single project from accidentally using more resources than intended and help ensure fair distribution across the platform.

This page includes OpenStack CLI commands. See the API Access documentation for instructions on how to install and configure the command line client.

What is quota-controlled

Each project has quotas for the following resource types:

Resource Description
Instances Maximum number of virtual machines
VCPUs Total number of virtual CPU cores across all instances
RAM Total memory across all instances (in MB)
Volumes Maximum number of block storage volumes
Volume storage Total storage across all volumes (in GB)
Volume snapshots Maximum number of volume snapshots
Security groups Maximum number of security groups
Security group rules Maximum number of rules across all security groups

Public IP addresses and networking

Safespring uses Calico as its networking engine, which does not use the floating IP concept found in traditional OpenStack deployments. To give an instance a public IP address, attach it to the public network when launching it. To remove public access, detach the instance from the public network and use the default network instead.

Never attach more than one network interface to an instance

Each network assigns a default gateway to the instance via DHCP. If an instance is attached to multiple networks (for example both public and default), it will receive two default gateways, leading to asymmetrical routing and unstable network connectivity. Always attach exactly one network interface per instance.

If you need the instance's IP address to survive instance recreation (for example during a restore process or a flavor change), consider creating a Network Port instead of assigning a network directly. The port retains its IP address independently of the instance. See Persistent IP addresses for details.

For more details on the available networks, see the Network section in Getting Started. For a deeper understanding of how networking works on the Safespring platform, see the blog post Networking at Safespring.

Viewing quotas in the dashboard

The Overview page in the Horizon dashboard shows your current resource usage as pie charts, with each chart comparing usage against the quota limit. This is the quickest way to check how much headroom you have in a project.

For more details on the dashboard overview, see the Getting Started documentation.

Viewing quotas with the CLI

Compute quotas

To see your compute quotas (instances, VCPUs, RAM):

openstack quota show

Storage quotas

To see your volume quotas:

openstack quota show --volume

Current usage

To see how much of each resource you are currently using:

openstack limits show --absolute

This shows both the limit and current usage for each resource type, making it easy to identify which quotas you are approaching.

Requesting a quota increase

Quotas are set by Safespring and cannot be changed by the customer directly. If you need more resources than your current quotas allow, contact Safespring support at support@safespring.com.

When requesting a quota increase, include:

  • The project name (e.g., prod.company.com)
  • Which resource type needs to be increased
  • The desired new limit
  • A brief description of why the increase is needed

See Getting support for more information on how to contact support.

Tips for managing quota usage

  • Clean up unused snapshots regularly, as they count against your storage quota. See the Snapshots HOWTO for more details.
  • Delete volumes that are no longer attached to any instance and no longer needed. Detached volumes still count against your quota.
  • Remove unused security groups and their rules if they are no longer in use.
  • Use openstack limits show --absolute to periodically check your usage before launching new instances, to avoid hitting a quota limit unexpectedly.
