Configure multiple Contrail API workers¶

TechPreview

Tungsten Fabric MOSK deployments use six workers of the contrail-api service by default. This section instructs you on how to change the default configuration if needed.

To configure the number of Contrail API workers on a TF deployment:

Specify the required number of workers in the TFOperator custom resource:

spec:
 features:
   config:
     configApiWorkerCount: 7

Wait until all tf-config-* pods are restarted.
Verify the number of workers inside the running API container:
```
kubectl -n tf exec -ti tf-config-rclzq -c api -- ps aux --width 500
kubectl -n tf exec -ti tf-config-rclzq -c api -- ls /etc/contrail/
```
Verify that the ps output lists one API process with PID "1" and the number of workers set in the TFOperator custom resource.
In /etc/contrail/, verify that the number of configuration files contrail-api-X.conf matches the number of workers set in the TFOperator custom resource.
