Installation with init configuration

karmadactl init allows you to install Karmada by specifying a configuration file, which provides a structured way to define all settings in a YAML file.

Example Configuration File

Here is an example of the configuration file for Karmada deployment:

apiVersion: config.karmada.io/v1alpha1
kind: KarmadaInitConfig
spec:
  karmadaCrds: "https://github.com/karmada-io/karmada/releases/download/v1.10.3/crds.tar.gz"
  etcd:
    local:
      imageRepository: "registry.k8s.io/etcd"
      imageTag: "3.5.13-0"
      initImage:
        imageRepository: "docker.io/library/alpine"
        imageTag: "3.19.1"
  components:
    karmadaAPIServer:
      imageRepository: "registry.k8s.io/kube-apiserver"
      imageTag: "v1.30.0"
    karmadaAggregatedAPIServer:
      imageRepository: "docker.io/karmada/karmada-aggregated-apiserver"
      imageTag: "v1.10.3"
    kubeControllerManager:
      imageRepository: "registry.k8s.io/kube-controller-manager"
      imageTag: "v1.30.0"
    karmadaControllerManager:
      imageRepository: "docker.io/karmada/karmada-controller-manager"
      imageTag: "v1.10.3"
    karmadaScheduler:
      imageRepository: "docker.io/karmada/karmada-scheduler"
      imageTag: "v1.10.3"
    karmadaWebhook:
      imageRepository: "docker.io/karmada/karmada-webhook"
      imageTag: "v1.10.3"

Deploying Karmada with Configuration File

1.Save the example configuration above to a file, e.g., karmada-init-config.yaml.

2.Use the following command to deploy Karmada with the configuration file:

sudo karmadactl init --config /path/to/your/karmada-init-config.yaml

备注

You need to use sudo for elevated permissions because karmadactl creates a karmada-apiserver.config file at the /etc/karmada/ directory.

3.This configuration file allows you to define essential parameters, including:

• certificates: Defines certificate paths and validity period.
• etcd: Configures Etcd settings, including local or external Etcd options.
• hostCluster: Specifies host cluster API endpoint and kubeconfig.
• images: Configures image settings for components.
• components: Sets up replicas for API Server and other core components.
• karmadaDataPath: Defines the data path for Karmada.
• ...

If you need more information about the configuration file, please refer to the karmadactl init API reference.
