Kubernetes Quotas

Overview

K8SaaS enforces per-project cluster quotas independent of compute quotas. A cluster quota limits the total number of clusters a project can create. Cluster nodes also consume compute quota (vCPU, RAM, and storage) — both quota systems must have sufficient headroom for cluster creation to succeed. This page covers setting K8SaaS quotas, monitoring usage, and coordinating limits across both services.

Prerequisites

Cloud administrator role
Project IDs for the projects you wish to quota

Default Quota

By default, K8SaaS applies a platform-wide quota of 20 clusters per project. Projects without an explicit quota record use this default.

Set a Project Quota

Dashboard
CLI

Navigate to Quotas

Navigate to Container (admin view) > Quotas.

Create or edit quota

Click Create Quota and fill in:

Field	Description	Example
Project	Target project	`production-team`
Hard Limit (Clusters)	Maximum clusters allowed	`10`

Save

Click Create. The quota takes effect immediately for the selected project.

Project quota is set and visible in the quota list.

Create a quota for a project

openstack coe quota create \
  --project <project-id> \
  --hard-limit 10 \
  kubernetes

Show quota for a project

openstack coe quota show \
  --project <project-id> \
  kubernetes

List all project quotas

openstack coe quota list

Set conservative limits for development projects (3–5 clusters) and higher limits for production projects (10–20). Coordinate with compute quota to ensure sufficient resources for the maximum expected cluster footprint.

Compute Quota Coordination

K8SaaS cluster nodes consume compute resources. Use the following formula to estimate the compute quota needed for a project’s K8SaaS allocation:

Total vCPU needed = (master_flavor_vcpu × master_count + worker_flavor_vcpu × worker_count) × max_clusters
Total RAM needed  = (master_flavor_ram_gb × master_count + worker_flavor_ram_gb × worker_count) × max_clusters

Example: 5 clusters × (3 masters × 8 vCPU + 6 workers × 4 vCPU) = 5 × (24 + 24) = 240 vCPU

Check current project compute quota

openstack quota show --detail <project-id>

Increase compute quota for a project

openstack quota set \
  --cores 240 \
  --ram 491520 \
  <project-id>

Monitor Quota Usage

Dashboard
CLI

Navigate to Container (admin view) > Quotas to view current usage versus limit for all projects. Click a project to see individual cluster details.

Show quota usage for a specific project

openstack coe quota show \
  --project <project-id> \
  kubernetes

The output shows hard_limit and in_use values:

hard_limit = 10
in_use = 3

Count active clusters in a project

openstack coe cluster list --all \
  | grep <project-name> | wc -l

Update an Existing Quota

Update an existing cluster quota

openstack coe quota update \
  --project <project-id> \
  --hard-limit 20 \
  kubernetes
