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.

Enable contrail-tools

The contrail-tools container provides a centralized location for all available Tungsten Fabric tools and CLI commands. The container includes such utilities as vif, flow, nh, and other tools to debug network issues. MOSK deploys contrail-tools using the Tungsten Fabric Operator through the TFOperator custom resource.

To enable the Tungsten Fabric contrail-tools Deployment:

  1. Enable the tools Deployment in the TFOperator resource for the operator to start the Pods with utilities to debug Tungsten Fabric on nodes with the tfvrouter:enabled label:

    spec:
  features:
    tfTools:
      tfToolsEnabled: true
      labels:
        tfvrouter: enabled

    spec:
  controllers:
    tf-tool:
      tools:
        enabled: true
        labels:
          tfvrouter: enabled

    Note

    Use the labels section to specify target nodes for the contrail-tools Deployment. If the labels section is not specified, the tf-tool-ctools-<xxxxx> Pods will be scheduled to all available nodes in current Deployment.

  2. Wait until the tf-tool-ctools-<xxxxx> Pods are ready in the tf namespace.

    Note

    The <xxxxx> string in a Pod name consists of random alpha-numeric symbols generated by Kubernetes to differentiate the tf-tool-ctools Pods.

  3. Use interactive shell in the tf-tool-ctools-<xxxxx> Pod to debug current Deployment or run commands through kubectl, for example:

    kubectl -n tf exec tf-tool-ctools-<xxxxx> -- vif --list

  4. Disable the tools Deployment:

    kubectl -n tf patch tfoperator.tf.mirantis.com <TFOperator CR name> --type='json' -p='[{"op": "replace", "path": "/spec/features/tfTools/tfToolsEnabled", "value": false}]'

    kubectl -n tf patch tfoperator.operator.tf.mirantis.com <TFOperator CR name> --type='json' -p='[{"op": "replace", "path": "/spec/controllers/tf-tool/tools/enabled", "value": false}]'
