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:

  1. apiVersion: config.karmada.io/v1alpha1
  2. kind: KarmadaInitConfig
  3. spec:
  4.   karmadaCrds: "https://github.com/karmada-io/karmada/releases/download/v1.10.3/crds.tar.gz"
  5.   etcd:
  6.     local:

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:

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

Installation with CLI - 图1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.
