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 svc/deckhouse-leader -- 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: '1.27'
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:

  • apiVersion
    string

    Required value

    Version of the Deckhouse API.

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

  • cloud
    object

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

    • cloud.prefix
      string

      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.provider
      string

      Required value

      Cloud provider.

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

  • clusterDomain
    string

    Required value

    Cluster domain (used for local routing).

    Please note: the domain must not match the domain used in the DNS name template in the publicDomainTemplate parameter. For example, you cannot set cluster Domain: cluster.local and publicDomainTemplate: %s.cluster.local at the same time.

    Default: "cluster.local"

  • clusterType
    string

    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

  • defaultCRI
    string

    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

  • kind
    string

    Required value

    Allowed values: ClusterConfiguration

  • kubernetesVersion
    string

    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. If the stable version of control plane is less than the maximum version that has ever been installed in the cluster, more than 1 minor version, then the version of the cluster will not be changed. The version may change when the minor version of the Deckhouse release is changed (see a corresponding release message).

    Allowed values: 1.26, 1.27, 1.28, 1.29, 1.30, Automatic

  • podSubnetCIDR
    string

    Required value

    Address space of the cluster’s Pods.

    Caution! Normally, you won’t be able to change the parameter in a running cluster. To avoid this limitation use specific flag.

  • podSubnetNodeCIDRPrefix
    string

    The prefix of Pod network on a node.

    Caution! Normally, you won’t be able to change the parameter in a running cluster. To avoid this limitation use specific flag.

    Default: "24"

  • proxy
    object

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

    The parameters described in this section will be translated into the environment variables HTTP_PROXY, HTTPS_PROXY, and NO_PROXY for all cluster nodes and Deckhouse components. This will result in HTTP(S) requests (curl, git, registry, etc.) to all resources not listed in the noProxy parameter being made through a proxy. Note that the podSubnetCIDR and serviceSubnetCIDR subnets, as well as the clusterDomain domain are added to noProxy automatically.

    Caution! To avoid interfering with internal requests, make sure you list all the host subnets in the noProxy parameter.

    This feature is available in enterprise edition only.

    • proxy.httpProxy
      string

      Proxy URL for HTTP requests.

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

      This feature is available in enterprise edition only.

      Pattern: ^https?://([!*'();&=+$,/?%#\[\]0-9a-zA-Z\.\-\_]+(\:[!*'();:@&=+$,/?%#\[\]0-9a-zA-Z\.\-\_]+)?@)?[0-9a-zA-Z\.\-]+(\:[0-9]{1,5})?$

      Examples:

      httpProxy: http://proxy.company.my

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

      httpProxy: https://DOMAIN%5Cuser:password@proxy.company.my:8443

      httpProxy: https://user%40domain.local:password@proxy.company.my:8443
    • proxy.httpsProxy
      string

      Proxy URL for HTTPS requests.

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

      This feature is available in enterprise edition only.

      Pattern: ^https?://([!*'();&=+$,/?%#\[\]0-9a-zA-Z\.\-\_]+(\:[!*'();:@&=+$,/?%#\[\]0-9a-zA-Z\.\-\_]+)?@)?[0-9a-zA-Z\.\-]+(\:[0-9]{1,5})?$

      Examples:

      httpsProxy: http://proxy.company.my

      httpsProxy: https://user:password@proxy.company.my:8443

      httpsProxy: https://DOMAIN%5Cuser:password@proxy.company.my:8443

      httpsProxy: https://user%40domain.local:password@proxy.company.my:8443
    • proxy.noProxy
      array of strings

      List of no proxy IP and domain entries.

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

  • serviceSubnetCIDR

      Allowed values: Minimal, Managed, Default

    • deckhouse.configOverrides
      Deprecated

      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:
