Missing PATH on kubeless.js runtime #62

juanxhos · 2020-03-04T16:17:32Z

Is this a BUG REPORT or FEATURE REQUEST?:
BUG REPORT

What happened:
When I send request with path ping using kubeless.js middleware it send / instead of the path

What you expected to happen:
to send the path requested

How to reproduce it (as minimally and precisely as possible):
curl --header "Host: kubernetes.docker.internal.nip.io" localhost/ping
and logs says

on AWS, works fine: because there is path sending...

Anything else we need to know?:

I found out in runtime:
https://github.com/kubeless/runtimes/blob/master/stable/nodejs/lib/helper.js#L38-L50
there no funtion for *
I would expect something like:

function routeAll(expressApp, promClient) {
  expressApp.get('/*', (req, res) => {
    return {req, res}
  });
}

I do not know if it works

mm, I am not able to reproduce your issue, are you using an HTTP trigger?

In my case, I have deployed the sample nodejs function and a simple HTTP trigger:

▶ kubeless function deploy get-nodejs --runtime nodejs6 --handler helloget.foo --from-file nodejs/helloget.js
▶ kubeless trigger http create get-nodejs --function-name get-nodejs

I can see the path logged when I am doing requests:

▶ curl -H "Host: get-nodejs.127.0.0.1.nip.io" localhost:30080/foobar
hello world!%

        url: '/foobar',
        originalUrl: '/foobar',
     url: '/foobar',
     originalUrl: '/foobar',
        pathname: '/foobar',
        path: '/foobar',
        href: '/foobar',
        _raw: '/foobar' },
     params: { '0': '/foobar' },
        url: '/foobar',
        originalUrl: '/foobar',
::ffff:10.244.0.5 - - [05/Mar/2020:10:48:42 +0000] "GET /foobar HTTP/1.1" 200 - "-" "curl/7.58.0"

can you share your repo, please
and what version are you using ??

andresmgot · 2020-03-06T08:19:40Z

I am using the helloget example from this repo (I only added a console.log of the request to print more info):

https://github.com/kubeless/runtimes/blob/master/stable/nodejs/examples/helloget.js

I am using kubeless 1.0.6.

In your case, I believe it's an issue with the HTTP trigger/ingress configuration. How did you create it? What ingress controller are you using?

juanxhos · 2020-03-06T13:29:36Z

Thanks I found out the problem, it's on plugin serverless-kubeless

https://github.com/serverless/serverless-kubeless/blob/master/lib/deploy.js#L533

looks like there is no definition function to create HTTPTrigger

apiVersion: kubeless.io/v1beta1
kind: HTTPTrigger
metadata:
 name: cors-trigger
 annotations:
  nginx.ingress.kubernetes.io/enable-cors: "true"
  nginx.ingress.kubernetes.io/cors-allow-methods: "GET"
spec:
 function-name: get-python
 host-name: example.com
 path: echo

I know there are 3 types of httptrigger, but at least can do something for at least nginx default type ?

andresmgot · 2020-03-06T14:21:23Z

Ah, yes, the serverless-kubeless creates an Ingress resource directly rather than creating an HTTP Trigger (which is the Kubeless abstraction). I recommend you to use the kubeless CLI to create the HTTP trigger since the serverless plugin is a bit behind regarding functionality.

In any case we are open to contributions for any project in case anyone wants to fix the issue there.

juanxhos · 2020-03-06T20:46:35Z

Nice... I am looking forward. Better if you have a Doc to setup an dev env for help on issues.

andresmgot · 2020-03-09T08:13:17Z

We have a bit of documentation for the Kubeless main project (https://kubeless.io/docs/dev-guide/) but unfortunately not here
