Kong: Google Cloud Function

Created on 27 Sep 2016 · 8Comments · Source: Kong/kong

Support the Google Serverless platform https://cloud.google.com/functions/ similar to AWS Lambda #1005.

A Kong plugin allows to invoke and manage GCfunctions directly from the gateway.

Turns out a full blown integration for Google Functions may not be needed. The fact that Google Functions automaticially provides an http URL, you can just proxy to it easy. The following works just fine following the helloGET tutorial.

curl -i -X POST http://localhost:8001/apis/ \
    -d 'name=helloGET' \
    -d 'upstream_url=https://us-central1-project-id.cloudfunctions.net/helloGET' \
    -d 'hosts=host.local' \
    -d 'methods=GET' \
    -d 'https_only=true'

curl -v -k https://localhost:8443/ -H 'Host: host.local'
*   Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 8443 (#0)
* TLS 1.2 connection using TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
* Server certificate: localhost

@jeremylorino this would be a good place: https://getkong.org/docs/0.9.x/plugin-development/

Has anyone started working on this? I'm considering it for project, and would be glad to work on it if no one else has already.

As far as I know, not yet @dustinblackman

Any updates on this?

bharathrajbk on 24 Apr 2019

@dustinblackman's example only works for unauthenticated functions. Is there any update on a real Google Cloud Functions plugin? I.e. calling an _authenticated_ Cloud Function via its HTTP trigger while providing the proper authentication token e.g. acquired from the Compute metadata endpoint.
