[Arvinzhu]

Description

1. I had read the content of this webpage(https://github.com/fnproject/docs/blob/master/fn/operate/runner_pools.md) and deployed fn-lb. result:

[root@localhost fn]# docker ps

2. test invoke result

[root@localhost fn]# curl -X POST http://lb.fn.local:8181/t/testapp/pyfn
{"message": "Hello World"}

3. Then I want to run fn/ui as development pattern with this webpage(https://github.com/fnproject/ui)

this command is:

[root@localhost ui]# PORT=6200 FN_API_URL=http://lb.fn.local:8181 npm start

> [email protected] start /root/fn/ui
> node server

info: Using API url: lb.fn.local:8181
info: Server running on port 6200
error: [ERR] 404 | Path not found: GET /v2/apps
error: Error. Api responded with  404 Path not found: GET /v2/apps

Something wrong occured! I opened http://localhost:6200 in browser.but can not load fn apps Info. Describe the results you received:

Then I stop ui and run other command. change the port as API SERVER port.

[root@localhost ui]# PORT=6200 FN_API_URL=http://lb.fn.local:8080 npm start

> [email protected] start /root/fn/ui
> node server

info: Using API url: lb.fn.local:8080
info: Server running on port 6200

this page(http://localhost:6200) can load apps info.

but when I test invoke the function ,something is not right.

so I try to run the command on the command line ,the result returned right!!!

[root@localhost fn]# curl -X POST -d '{"name":"Pony"}' http://lb.fn.local:8181/invoke/01DNM3Z752NG8G00RZJ000000K
Hello, {"name":"Pony"}!

Describe the results you expected: I hope someone could tell me how to deploy lb and ui properly. Thanks!
