Anka Build Cloud Controller & Registry Version 1.51.0
Instance Quotas
You can limit the number of instances that a credential and/or group can use by creating a Permission Group and setting the max instance quota.

To enable this feature in your Controller configuration file, set ANKA_ENABLE_INSTANCE_QUOTAS=true and ANKA_ENABLE_AUTH="true".
IMPORTANT UPGRADE NOTE FOR HIGH AVAILABILITY SETUPS:
Quotas must remain disabled until every controller is upgraded. To disable, set ANKA_ENABLE_INSTANCE_QUOTAS=false or remove the ENV entirely.To use this feature, you need to create a new Permission Group. Then, you can specify the max instance quota for the group under the Instance Quotas page.
