Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!

Starting with MOSK 25.2, the MOSK documentation set covers all product layers, including MOSK management (formerly Container Cloud). This means everything you need is in one place. Some legacy names may remain in the code and documentation and will be updated in future releases. The separate Container Cloud documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

IPaddr

This section describes the IPaddr resource used in the management API. The IPAddr object describes an IP address and contains all information about the associated MAC address.

For demonstration purposes, the IPaddr custom resource (CR) is split into the following major sections:

IPaddr metadata

The IPaddr CR metadata contains the following fields:

  • apiVersion

    API version of the object that is ipam.mirantis.com/v1alpha1.

  • kind

    Object type that is IPaddr.

  • metadata

    The metadata field contains the following subfields:

    • name

      Name of the IPaddr object in the auto-XX-XX-XX-XX-XX-XX format where XX-XX-XX-XX-XX-XX is the associated MAC address.

    • namespace

      Project in which the IPaddr object was created.

    • labels

      Key-value pairs that are attached to the object:

      • ipam/IP

        IPv4 address

      • ipam/IpamHostID

        Unique ID of the associated IpamHost object

      • ipam/MAC

        MAC address

      • ipam/SubnetID

        Unique ID of the Subnet object

      • ipam/UID

        Unique ID of the IPAddr object

      Warning

      Labels and annotations that are not documented in this API Reference are generated automatically. Do not modify them using the API.

Configuration example:

apiVersion: ipam.mirantis.com/v1alpha1
kind: IPaddr
metadata:
  name: auto-0c-c4-7a-a8-b8-18
  namespace: default
  labels:

    ipam/UID: 84925cac-f804-11ea-88c8-0242c0a85b02

IPAddr spec

The spec object field of the IPAddr resource contains the associated MAC address and the reference to the Subnet object:

  • mac

    MAC address in the XX:XX:XX:XX:XX:XX format

  • subnetRef

    Reference to the Subnet resource in the <subnetProjectName>/<subnetName> format

Configuration example:

spec:
  mac: 0C:C4:7A:A8:B8:18
  subnetRef: default/kaas-mgmt

IPAddr status

  • address

    IP address.

  • cidr

    IPv4 CIDR for the Subnet.

  • gateway

    Gateway address for the Subnet.

  • mac

    MAC address in the XX:XX:XX:XX:XX:XX format.

  • nameservers

    List of the IP addresses of name servers of the Subnet. Each element of the list is a single address, for example, 172.18.176.6.

  • state Since MCC 2.23.0 (11.7.0)

    Message that reflects the current status of the resource. The list of possible values includes the following:

    • OK - object is operational.

    • ERR - object is non-operational. This status has a detailed description in the messages list.

    • TERM - object was deleted and is terminating.

  • messages Since MCC 2.23.0 (11.7.0)

    List of error or warning messages if the object state is ERR.

  • objCreated

    Date, time, and IPAM version of the resource creation.

  • objStatusUpdated

    Date, time, and IPAM version of the last update of the status field in the resource.

  • objUpdated

    Date, time, and IPAM version of the last resource update.

  • phase

    Deprecated since Container Cloud 2.23.0 (Cluster release 11.7.0) and will be removed in one of the following releases in favor of state. Possible values: Active, Failed, or Terminating.

Configuration example:

status:
  address: 172.16.48.201
