This project is aimed to help Kubernetes adminitrators define resource limit ranges dynamically for all namespaces.

Limit Operator

A Kubernetes Operator based on the Operator SDK for cluster level resource configuration.

Current status

This is a PoC / alpha version. Most functionality is there but it is higly likely there are bugs and improvements needed

Supported Custom Resources

The following resources are supported:

• ClusterLimit

ClusterLimit

Represents a LimitRange and a namespace Selector for the Operator to install this LimitRange to.

Test it locally

Refer to the Operator SDK docs in order to setup local development environment and spin up operator.

Deploying to a Cluster

Before the Limit Operator can be deployed to a running cluster, the necessary Custom Resource Definitions (CRDs) must be installed. To do this, run kubectl apply -f deploy/crds/.

Then run

• kubectl apply -f deploy/service_account.yaml
• kubectl apply -f deploy/role.yaml -n <NAMESPACE>
• kubectl apply -f deploy/role_binding.yaml
• kubectl apply -f deploy/operator.yaml -n <NAMESPACE>

Create a ClusterLimit

• kubectl apply -f examples/default.yaml
