Kwok in Cluster

Deploy kwok in a Cluster #

This document walks you through how to deploy kwok in a Kubernetes cluster.

Variables preparation #

# Temporary directory
KWOK_WORK_DIR=$(mktemp -d)
# KWOK repository
KWOK_REPO=kubernetes-sigs/kwok
# Get latest
KWOK_LATEST_RELEASE=$(curl "https://api.github.com/repos/${KWOK_REPO}/releases/latest" | jq -r '.tag_name')

Render kustomization yaml #

Firstly, generate a kustomization template yaml to the previously-defined temporary directory.

cat <<EOF > "${KWOK_WORK_DIR}/kustomization.yaml"
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
images:
  - name: registry.k8s.io/kwok/kwok
    newTag: "${KWOK_LATEST_RELEASE}"
resources:
  - "https://github.com/${KWOK_REPO}/kustomize/kwok?ref=${KWOK_LATEST_RELEASE}"
EOF

Next, render it with the prepared variables.

kubectl kustomize "${KWOK_WORK_DIR}" > "${KWOK_WORK_DIR}/kwok.yaml"

kwok deployment #

Finally, we’re able to deploy kwok:

kubectl apply -f "${KWOK_WORK_DIR}/kwok.yaml"

Next steps #

Now, you can use kwok to manage nodes and pods in the Kubernetes cluster.
