 fx is a tool to help you do Function as a Service on your own server, fx can make your stateless function a service in seconds, both Docker host and Kubernetes cluster supported. The most exciting thing is that you can write your functions with most programming languages.

+**fx** is originally designed to turn a function into a runnable Docker container in a easiest way, on a host with Docker running, you can just deploy your function with `fx up` command,  and now **fx** supports deploy function to be a service onto Kubernetes cluster infrasture, and we encourage you to do that other than on bare Docker environment, there are lots of advantage to run your function on Kubernetes like self-healing, load balancing, easy horizontal scaling, etc. It's pretty simple to deploy your function onto Kubernetes with **fx**, you just set KUBECONFIG in your enviroment.
+
+By default. **fx** use localhost as target infrastructure to run your service, and you can also setup your remote virtual machines as **fx**'s infrastructure and deploy your functions onto it.
+
+### `fx infra create`
+
+You can create types (docker and k8s) of infrastructures for **fx** to deploy functions
 
 ```shell
-fx up --name hello-svc --port 7777 hello.js # onto localhost
-DOCKER_REMOTE_HOST_ADDR=xx.xx.xx.xx DOCKER_REMOTE_HOST_USER=xxxx DOCKER_REMOTE_HOST_PASSWORD=xxxx fx up --name hello-svc --port 7777 hello.js # onto remote host

 ```

-**fx** supports deploy function to be a service onto Kubernetes cluster infrasture, and we encourage you to do that other than on bare Docker environment, there are lots of advantage to run your function on Kubernetes like self-healing, load balancing, easy horizontal scaling, etc. It's pretty simple to deploy your function onto Kubernetes with **fx**, you just set KUBECONFIG in your enviroment.
+To use a infrastructure, you can use `fx infra use` command to activate it.
 
 ```shell
-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
+fx infra use <infrastructure name>
 ```
 
-or
+and you can list your infrastructure with `fx infra list`
 
-```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
-```
-
-* Local Kubernetes Cluster
-
-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`.
-
-```shell
-$ export KUBECONFIG=~/.kube/config  # then fx will take the config to deloy function
-```
-
-if you have multiple Kubernetes clusters configured, you have to set context correctly. FYI [configure-access-multiple-clusters](https://kubernetes.io/docs/tasks/access-application-cluster/configure-access-multiple-clusters/)
