Cloud provider — OpenStack: configuration

Schema version: 1

• settings

  object
  • settings.additionalExternalNetworkNames

    array of strings

    Specifies additional networks that can be connected to the VM. cloud-controller-manager uses them to insert ExternalIP to .status.addresses field in the Node API object.

    If you have instances in the cluster that use External Networks (other than those set out in the placement strategy), you must pass them via the additionalExternalNetworkNames parameter.

    Example:

    additionalExternalNetworkNames:
    - some-bgp-network
    

  • settings.connection

    object

    This section contains parameters required to connect to the cloud provider’s API.

    • settings.connection.authURL

      string

      An OpenStack Identity API URL.

    • settings.connection.caCert

      string

      Specify the CA x509 certificate used for signing if the OpenStack API has a self-signed certificate; The certificate must have a PEM format.

    • settings.connection.domainName

      string

      The domain name.

    • settings.connection.password

      string

      The user’s password.

    • settings.connection.region

      string

      The OpenStack region where the cluster will be deployed.

    • settings.connection.tenantID

      string

      The project ID. Cannot be used together with tenantName.

    • settings.connection.tenantName

      string

      The project name.

      Cannot be used together with tenantID.

    • settings.connection.username

      string

      The name of the user that has full project privileges.

  • settings.externalNetworkNames

    array of strings

    Additional networks that are connected to the VM. cloud-controller-manager uses them to insert ExternalIPs into .status.addresses in the Node API object.

    Example:

    externalNetworkNames:
    - KUBE-3
    - devops-internal
    

  • settings.ignoreVolumeMicroversion

    boolean

    Setting for backwards compatibility. Enable if the cloud OpenStack version is less than 3.34 and you get error “Version 3.34 is not supported by the API. Minimum is 3.0 and maximum is 3.x” when ordering a PV. This will disable volumes online resize, but will restore ability to order new PVs. (original PR https://github.com/kubernetes/cloud-provider-openstack/pull/1986/)

    Default: false

  • settings.instances

    object

    Instance parameters that are used when creating virtual machines.

    • settings.instances.additionalNetworks

      array of strings

      A list of networks to connect to the instance.

    • settings.instances.imageName

      string

      The name of the image.

    • settings.instances.mainNetwork

      string

      The path to the network that will serve as the primary network (the default gateway) for connecting to the VM.

    • settings.instances.securityGroups

      array of strings

      A list of securityGroups to assign to the provisioned instances. Defines firewall rules for the provisioned instances.

    • settings.instances.sshKeyPairName

      string

      The name of the OpenStack keypair resource; it is used for provisioning instances.

  • settings.internalNetworkNames

    array of strings

    Additional networks that are connected to the VM. cloud-controller-manager uses them to insert InternalIPs into .status.addresses in the Node API object.

    Example:

    internalNetworkNames:
    - KUBE-3
    - devops-internal
    

  • settings.loadBalancer

    object

    Load Balancer parameters.

    • settings.loadBalancer.floatingNetworkID

      string

      An ID of the external network for floating IPs.

    • settings.loadBalancer.subnetID

      string

      An ID of the Neutron subnet to create the load balancer virtual IP in.

  • settings.podNetworkMode

    string

    Sets the traffic mode for the network that the pods use to communicate with each other (usually, it is an internal network; however, there can be exceptions):

    • DirectRouting — means that there is a direct routing between the nodes.
    • DirectRoutingWithPortSecurityEnabled — direct routing is enabled between the nodes, but only if the range of addresses of the internal network is explicitly allowed in OpenStack for Ports.
      • Caution! Make sure that the username can edit AllowedAddressPairs on Ports connected to the internalNetworkName network. Generally, an OpenStack user doesn’t have such a privilege if the network has the shared flag set.
    • VXLAN — direct routing between the nodes isn’t available; VXLAN should be used.

    Allowed values: DirectRouting, DirectRoutingWithPortSecurityEnabled, VXLAN

  • settings.storageClass

    object

    The module automatically creates StorageClasses that are available in OpenStack.

    • settings.storageClass.default

      string

      The name of StorageClass that will be used in the cluster by default.

      If the parameter is omitted, the default StorageClass is either:

      • an arbitrary StorageClass present in the cluster that has the default annotation;
      • the first StorageClass created by the module (in accordance with the order in OpenStack).

      Example:

      default: ceph-ssd
      

    • settings.storageClass.exclude

      array of strings

      A list of StorageClass names (or regex expressions for names) to exclude from the creation in the cluster.

      Example:

      exclude:
      - ".*-hdd"
      - iscsi-fast
      

    • settings.storageClass.topologyEnabled

      boolean

      This feature enables driver to consider the topology constraints while creating the volume. It is used only during volume provisioning, existing PersistentVolumes are not affected.

      Note! If it is set to false all-new PersistentVolumes are provisioned without topology constraints.

      Default: true

  • settings.tags

    object

    A dictionary of tags that will be available on all provisioned instances.

  • settings.zones

    array of strings

    The default list of zones for provisioning instances. Can be redefined for each NodeGroup individually.
