Reference of the resources used during Deckhouse installation.

ClusterConfiguration

Version: deckhouse.io/v1

General parameters of a cluster.

Defines, for example, network and CRI parameters, control plane version, etc. Some parameters can be changed after the cluster is bootstrapped, during its operation.

To change the ClusterConfiguration resource in a running cluster, run the following command:

kubectl -n d8-system exec -ti deploy/deckhouse -- deckhouse-controller edit cluster-configuration

Example:

apiVersion: deckhouse.io/v1
kind: ClusterConfiguration
podSubnetNodeCIDRPrefix: '24'
podSubnetCIDR: 10.244.0.0/16
serviceSubnetCIDR: 192.168.0.0/16
kubernetesVersion: '1.23'
clusterDomain: k8s.internal
clusterType: Cloud
cloud:
  prefix: k8s-dev
  provider: Yandex
proxy:
  httpProxy: https://user:password@proxy.company.my:8443
  httpsProxy: https://user:password@proxy.company.my:8443
  noProxy:
  - company.my
  • apiVersionstring

    Required value

    Version of the Deckhouse API.

    Allowed values: deckhouse.io/v1, deckhouse.io/v1alpha1

  • cloudobject

    Cloud provider-related settings (if the Cloud clusterType is used).

    • cloud.prefixstring

      A prefix of the objects to be created in the cloud.

      Is used, for example, to distinguish objects created for different clusters, to configure routing, etc.

      Pattern: ^[a-z0-9]([-a-z0-9]*[a-z0-9])?$

    • cloud.providerstring

      Required value

      Cloud provider.

      Allowed values: OpenStack, AWS, GCP, Yandex, vSphere, Azure

  • clusterDomainstring

    Required value

    Cluster domain (used for local routing).

    Default: "cluster.local"

  • clusterTypestring

    Required value

    Type of the cluster infrastructure:

    • Static — a cluster on bare metal (physical servers) or virtual machines. In the case of virtual machines, it is assumed that Deckhouse doesn’t have access to the API for managing virtual machines (they are managed by the administrator using the usual cloud infrastructure tools);
    • Cloud — a cluster deployed on the resources of a cloud infrastructure. This type implies that Deckhouse has access to the cloud infrastructure API for managing virtual machines.

    Allowed values: Cloud, Static

  • defaultCRIstring

    The container runtime type that used on cluster nodes (NodeGroups) by default.

    If the value NotManaged is used, then Deckhouse does not manage the container runtime (and doesn’t install it). In this case, it is necessary to use images for NodeGroups on which the container runtime is already installed.

    Default: "Containerd"

    Allowed values: Docker, Containerd, NotManaged

  • kindstring

    Required value

    Allowed values: ClusterConfiguration

  • kubernetesVersionstring

    Required value

    Kubernetes control plane version to use in a cluster.

    Changing a parameter in a running cluster will automatically update the cluster’s control plane version.

    If Automatic is specified, then the control plane version is used, which is considered stable at the moment. The version may change when the minor version of the Deckhouse release is changed (see a corresponding release message).

    Allowed values: 1.23, 1.24, 1.25, 1.26, 1.27, Automatic

  • podSubnetCIDRstring

    Required value

    Address space of the cluster’s Pods.

  • podSubnetNodeCIDRPrefixstring

    The prefix of Pod network on a node.

    Caution! Don’t change the parameter in a working cluster.

    Default: "24"

  • proxyobject

    Global proxy setup (especially for working in air-gapped environments).

    Caution! To avoid interference with internal requests it is important to fill noProxy parameter with host subnets.

    • proxy.httpProxystring

      Proxy URL for HTTP requests.

      If necessary, specify the proxy server’s username, password, and port.

      Pattern: ^https?://[0-9a-zA-Z\.\-:@]+$

      Examples:

      httpProxy: http://proxy.company.my

      httpProxy: https://user:password@proxy.company.my:8443
    • proxy.httpsProxystring

      Proxy URL for HTTPS requests.

      If necessary, specify the proxy server’s username, password, and port.

      Pattern: ^https?://[0-9a-zA-Z\.\-:@]+$

      Examples:

      httpsProxy: http://proxy.company.my

      httpsProxy: https://user:password@proxy.company.my:8443
    • proxy.noProxyarray of strings

      List of no proxy IP and domain entries.

      For wildcard domains, use a domain name with a dot prefix, e.g., “.example.com”.

      • Element of the arraystring

        Pattern: ^[a-z0-9\-\./]+$

  • serviceSubnetCIDRstring

    Required value

    Address space of the cluster’s services.

InitConfiguration

    • deckhouse.configOverridesobject

      Initial Deckhouse configuration.

      Structure format

      configOverrides:
  global:
    ... global parameters section
  <moduleName>Enabled: true|false
  <moduleName>:
    ... the module parameters section

      Caution! The module name in camelCase is used to enable/disable the module and specify its settings (for example, userAuthn) in the configOverrides structure. After installing Deckhouse, the moduleConfig resource is used to manage the module with the module name in snake-case (for example, user-authn).

      Example:

      configOverrides:
  global:
    modules:
      publicDomainTemplate: "%s.k8s.company.my"
  linstorEnabled: true
  monitoringPingEnabled: false
