Scalar-Operator

Scalar-Operator is a Kubernetes Operator designed to simplify scaling up deployments effortlessly.

Getting Started

To get started with the Scalar-Operator, follow the steps below:

1. Clone the repository from GitHub:

   git clone https://github.com/YashPimple/scalar-operator.git
   cd scalar-operator
   

2. Generate the Kubernetes manifests:

   make manifests
   

3. Apply the Custom Resource Definition (CRD):

   kubectl apply -f config/crd/bases/api.scalaroperator.io_scalars.yaml
   

4. Deploy an nginx deployment on your cluster (or any other deployment you wish to scale):

   kubectl create deployment nginx --image=nginx
   

5. Check the number of replicas running:

   kubectl get pods
   

6. Scale up the replicas using the Scalar-Operator:

   make run
   

7. Open another terminal and apply the Scalar custom resource to scale up the replicas:

   kubectl apply -f config/samples/api_v4alpha1_scaler.yaml
   

8. Finally, check the number of replicas:

   kubectl get pods
   

9. Output You should see an output similar to the following:

   yashpimple@Yashs-Air ~ % kubectl get pods
   NAME                    READY   STATUS              RESTARTS   AGE
