From Portainer CE 2.6 on,
Resource Pool(s) has been renamed to
Namespace(s) to be aligned with Kubernetes lingo.
Create a Namespace/Resource Pool
The Namespaces/Resource Pools are helpful when multiple teams are using the same cluster and there is potential collision, you can prevent this by using a virtual wall between multiple clusters. In this help article, you will learn how to create a Namespace/Resource Pool using Portainer.
Creating a Namespace/Resource Pool
Go to Namespaces/Resource Pools and then click Add Namespace/Resource pool.
In the next screen, you need to name your resource pool, assign a quota (Optional), set the resource limits of that quota indicating how much memory and CPU is assigned to this Namespace/Resource Pool.
When everything is set, click Create resource pool.
If everything works as expected, you will see a pop up confirming the creation of this resource pool.
