Installation

To install the CRDs, apply the crds.yaml manifest for this version:

kubectl apply -f https://github.com/kubernetes-sigs/node-readiness-controller/releases/download/v0.2.0/crds.yaml

To install the controller, apply the install.yaml manifest for this version:

kubectl apply -f https://github.com/kubernetes-sigs/node-readiness-controller/releases/download/v0.2.0/install.yaml

Alternatively, to install with metrics enabled:

kubectl apply -f https://github.com/kubernetes-sigs/node-readiness-controller/releases/download/v0.2.0/install-with-metrics.yaml

To install with secure metrics enabled:

kubectl apply -f https://github.com/kubernetes-sigs/node-readiness-controller/releases/download/v0.2.0/install-with-secure-metrics.yaml

To install with webhook enabled:

kubectl apply -f https://github.com/kubernetes-sigs/node-readiness-controller/releases/download/v0.2.0/install-with-webhook.yaml

Note: secure metrics and webhook requires cert-manager crds to be installed in the cluster.

This will deploy the controller into any available node in the nrr-system namespace in your cluster. Check here for more installation instructions.
