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

Starting with MOSK 25.2, the MOSK documentation set will cover all product layers, including MOSK management (formerly MCC). This means everything you need will be in one place. The separate MCC documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

Tungsten Fabric deployment prerequisites

Before you proceed with the actual Tungsten Fabric (TF) deployment, verify that your deployment meets the following prerequisites:

  1. Your MOSK OpenStack cluster is deployed as described in Deploy an OpenStack cluster with the Tungsten Fabric backend enabled for Neutron using the following structure:

    spec:
  features:
    neutron:
      backend: tungstenfabric

  2. Your MOSK OpenStack cluster uses the correct value of features:neutron:tunnel_interface in the openstackdeployment object. The TF Operator will consume this value through the shared secret and use it as a network interface from the underlay network to create encapsulated tunnels with the tenant networks.

    Considerations for tunnel_interface

    • Plan this interface as a dedicated physical interface for TF overlay networks. TF uses features:neutron:tunnel_interface to create the vhost0 virtual interface and transfers the IP configuration from the tunnel_interface to the virtual one.

    • Do not use bridges from L2 templates as tunnel_interface. Such usage might lead to networking performance degradation and data plane downtime.

  3. The Kubernetes nodes are labeled according to the TF node roles:

    Kubernetes labels

    Minimal count

    TF control plane

    Hosts the TF control plane services such as database, messaging, api, svc, config.
    tfconfig=enabled
    tfcontrol=enabled
    tfwebui=enabled
    tfconfigdb=enabled

    3

    TF analytics Unsupported since {{ product_name_abbr }} 24.2

    Hosts the TF analytics services.
    tfanalytics=enabled
    tfanalyticsdb=enabled

    3

    TF vRouter

    Hosts the TF vRouter module and vRouter Agent.
    tfvrouter=enabled

    Varies

    Note

    TF supports only Kubernetes OpenStack workloads. Therefore, you should label OpenStack compute nodes with the tfvrouter=enabled label.

    Note

    Do not specify the openvswitch=enabled label for the OpenStack deployments with TF as a networking backend.
