Running development cluster

You can use KIND to get a local cluster for development.

cat <<EOF > kind-poc-cluster.yaml
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
name: poc
nodes:
- role: control-plane
- role: worker
- role: worker
featureGates:
  InPlacePodVerticalScaling: true

kind create cluster --config kind-poc-cluster.yaml

Deploying development version

1. Install CRDs on a cluster

   make install

2. Build docker image

   make docker-build IMG=kube-startup-cpu-boost:dev

3. Load docker image to development cluster

   kind load docker-image --name poc kube-startup-cpu-boost:dev

4. Enable development logging and other options if needed

   In config/default/kustomization.yaml uncomment the dev patch:

   # Uncomment below for development
   - manager_config_dev_patch.yaml

   Adapt the config/default/manager_config_dev_patch.yaml if needed.

5. Deploy controller on a cluster

   make deploy IMG=docker.io/library/kube-startup-cpu-boost:dev
