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:

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
```
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.
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.
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
```

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}]'
