Installing the Kairos Operator

Deploying the operator

To deploy the operator, you can use kubectl (provided that the git command is available):

# Using GitHub URL
kubectl apply -k https://github.com/kairos-io/kairos-operator/config/default

# Or using local directory (if you have the operator checked out)
kubectl apply -k config/default

When the operator starts, it will automatically detect Kairos nodes and label them with kairos.io/managed: true. This label can be used to target Kairos nodes specifically in hybrid clusters.

Removing the operator

# Using GitHub URL
kubectl delete -k https://github.com/kairos-io/kairos-operator/config/default

# Or using local directory
kubectl delete -k config/default

Installing via Bundle

You can also install the Kairos Operator using a bundle by adding the following configuration to your cloud-config file:

bundles:
  - targets:
      - run://quay.io/kairos/community-bundles:kairos-operator_latest

This will automatically deploy the operator during the node initialization process.

Removing the Bundle Installation

To remove the operator installed via bundle, you need to delete the kairos-operator.yaml file from the appropriate location:

• k0s: /var/lib/k0s/manifests/kairos-operator/
• k3s: /var/lib/rancher/k3s/server/manifests/
