+You can create types (docker and k8s) of infrastructures for **fx** to deploy functions

 ```shell

 ```

+### `fx infra use`

+To use a infrastructure, you can use `fx infra use` command to activate it.

 ```shell
-$ export KUBECONFIG=<Your KUBECONFIG>
-$ fx deploy -n fx-service-abc_js -p 12349 examples/functions/JavaScript/func.js   # function will be deploy to your Kubernetes cluster and expose a IP address of your loadbalencer

+and you can list your infrastructure with `fx infra list`

-Docker for Mac and Docker for Windows already support Kubernetes with single node cluster, we can use it directly, and the default `KUBECONFIG` is `~/.kube/config`.
