Not sure where to look for info on this, are there any plans for native support of Golang in google cloud functions? Feels a bit silly that AWS Lambda beat them to this.

If this isn't the right place to ask, any ideas about where we should would be great.

I have tried to compile multiple .go files with make & make test and throw a error instead if I use go run main.go my_other_code.go work ok, so I think is a matter of make stript.
Thanks

Hi!

I'm trying to deploy a Go Cloud Function, with PubSub trigger, but I'm always hitting this error:

{
 insertId:  "000000-0e31e000-5a9c-41f7-b40e-5af2eba5cdab"   
 labels: {
  execution_id:  ""    
 }
 logName:  "projects/infrasnukture/logs/cloudfunctions.googleapis.com%2Fcloud-functions"   
 receiveTimestamp:  "2018-07-26T11:27:35.175212742Z"   
 resource: {
  labels: {
   function_name:  "test-go1"     
   project_id:  "infrasnukture"     
   region:  "europe-west1"     
  }
  type:  "cloud_function"    
 }
 severity:  "ERROR"   
 textPayload:  "Failed to decode event: json: cannot unmarshal object into Go struct field EventContext.resource of type string
"   
 timestamp:  "2018-07-26T11:27:28.982Z"   
}

This is the payload of the PubSub message:

{
"data":{
    "data":"dGVzdA==",
    "attributes":{
      "age":"22"
    },
    "@type":"type.googleapis.com/google.pubsub.v1.PubsubMessage"
  }
}

And my main.go looks like this:

package main

import (
	"flag"
	"net/http"

	"./events"
	"./nodego"
)

func main() {
	flag.Parse()

	http.HandleFunc(nodego.PubSubTrigger, events.Handler(func(event *events.Event) error {
		nodego.InfoLogger.Printf("PubSub triggered Go function!")

		msg, err := event.PubSubMessage()
		nodego.InfoLogger.Printf("Your message: %s", msg.Data)
		if err != nil {
			return err
		}
		return nil
	}))

	nodego.TakeOver()
}

BTW, if I run it locally on my machine, it works fine.

Appreciate some help!

Hello, I would like to know if it is possible to make an authentication system using nodejs with passportjs or JWT integrated with Google Cloud Functions, which I want to know exactly if doing the authentication in GCF I do not have to authenticate every time I do an action and yes only authenticate once

When I tried to deploy function.zip I got the following error message on Google Cloud Functions:

Deployment failure: Operation interrupted.

This is what I did:

At first, clone and build:

$ git clone https://github.com/GoogleCloudPlatform/cloud-functions-go.git && cd cloud-functions-go
$ make

Then uploaded to Google Cloud Functions using the GCP web UI.

The following error entry is in the logs:

{
 insertId:  "-uie6zkd1h36"

I've been having a bad time trying to issue HTTP(S)-Requests from a Cloud Function that uses this package.

Consider this absolute minimal repro:

package main

import (
    "flag"
    "net/http"

    "github.com/GoogleCloudPlatform/cloud-functions-go/nodego"
)

func init() {
    nodego.OverrideLogger()
}

func main() {
    flag.Parse()

    http.HandleFunc(nodego.HTTPTrigger, nodego.WithLoggerFunc(func(w http.ResponseWriter, r *http.Request) {
        http.Get("http://example.com/")
    }))

    nodego.TakeOver()
}

When called, it always dies:

Function execution took 296 ms, finished with status: 'connection error'
Error: function crashed out of request scope Function invocation was interrupted.

Just when writing this, it occured to me to leave out the line nodego.OverrideLogger().
Now the Cloud Function finally does what it is supposed to.

Does anyone have a clue what's wrong here?

Getting this plain text response every 30 or so requests:

Error: could not handle the request

Checking the server logs I found this:

severity:  "ERROR"  
textPayload:  "Error: function crashed out of request scope
 Function invocation was interrupted.
" 

I've had two different issues with deployment I've since worked around.
Leaving this here for documentation, maybe it'll help others.

We use this module for Cloud Functions:
https://github.com/GoogleCloudPlatform/functions-framework-go

This repo looks old and should be deprecated. I found it out by accident.

@juliehockett do you have context for this repo?

Suggest using

use execve instead of execv so that users can set and launch a runtime which may require specific .so files or other env variables

For example:

	char *envp[] =
	{
			"LD_LIBRARY_PATH=/user_code/lib:$LD_LIBRARY_PATH",
			NULL
	};

	execve(bin, const_cast<char* const*>(&args[0]), envp);  

I tested and work very nice but I have a doubt where should I place my code and how in other to be isolate of runtime code.

nodego.go ?
main.go ?
other

I have tried to performance a query from one project A to a BigQuery in other project B and I am getting a error connection. (i am using a service-account)

Same app running locally works propertly. I have spent a lot time with permision, service account, token, credentials etc, etc.

Someone can confirm me that current version on c-f-go support cross projects environments.

thanks

ps. apoint to example will be perfect.

projectID := "xxxx"
ctx := context.Background()
jwt, err := google.JWTConfigFromJSON(getServiceAccount(), bigquery.Scope)
if err != nil {
	log.Fatal(err)
}
client, err := bigquery.NewClient(
        ctx,
	projectID,
	option.WithTokenSource(jwt.TokenSource(ctx)),
	)
if err != nil {
log.Fatal(err)
	}
```

I can't get this package for following reason.

$ go get github.com/GoogleCloudPlatform/cloud-functions-go
../../../github.com/GoogleCloudPlatform/cloud-functions-go/main.go:22:2: local import "./nodego" in non-local package

How to use this package?

Is there a way we can connect this library to a web server like (https://github.com/zenazn/goji)?

Right now the runtime binary is executed with the file descriptors as positional arguments and the application runtime has to check/interpret what the FD's are for.

Suggest adding in options to args for the parameter's intents

execv(bin, const_cast<char* const*>(&args[0]));

eg.
instead of
./main file_descriptor

you'd get

./main --listenfd file_descriptor

that way, i can opt-parse the arguments in main.go if i wanted to extend it.

I am trying to deploy my go/http project as a function with a command like

gcloud functions deploy table-viewer --verbosity=debug --entry-point LambdaX --runtime go111 --trigger-http --set-env-vars AUTH_LOGIN=login,...

.gcloudignore contains both

go.sum
go.mod

From the output :

INFO: Using .gcloudignore file at [.../table-viewer/.gcloudignore].
DEBUG: Skipping file [go.mod]
DEBUG: Skipping file [go.sum]
DEBUG: Skipping file [.gitignore]
DEBUG: Skipping file [vendor]
DEBUG: Skipping file [vendor/golang.org]
DEBUG: Skipping file [vendor/golang.org/x]
DEBUG: Skipping file [vendor/golang.org/x/sys]
...

Why it ignores vendor folder?

I have tried and it works very well and I love the idea of build my code using this architecture but I am concern about two stuff.
There will be a cloud-functions-go supported by google soon?
My environment is windows OS . Exists a workaround to build on windows box.

Thanks

I have just started using Cloud function - go to create a new application. On my first deployment, It took more than 10 minutes and at the end showed me the following error:

ERROR: (gcloud.functions.deploy) OperationError: code=10, message=Operation interrupted.

I have a couple of issues with the deployment so far:

• There is no way or at least I couldn't find it in documentation to see the deployment log as it happens
• It fails without any further information!

Would be great if someone can shed a light on this issue as I am currently stuck

https://cloud.google.com/blog/products/application-development/cloud-functions-go-1-11-is-now-a-supported-language

When I tried the first time locally all work propertly but when click refresh failing with a 404 page no found using your code without changed .

We are using cloud-functions but lately it is apparently stopped someone can tell us some updated

thanks

I tried both log.Println and fmt.Println, neither appeared in the cloud function's log

This is a longer term FR:

At the moment, the build and test steps requires gcc,make nodejs. However, those are only needed if you want to deploy with functions.zip or run the test node server.

Suggestion is two part:

allow users to run cloud function alone locally using native toolchains and not deal with node and the execv.
The advantage of this is you don't need node, make, gcc or anything and can elect to acquire them during deployment by other means.

By other means i mean like build node_modules and execve entirely in docker and then "copy" them to your workstation just prior to creating functions.zip.

This would require the runtime binary to accept both sockets as arguments as well as listen on its own (eg:)

http.ListenAndServe(":8080", nil)

The following dockerfile is an example of this 'just in time' library/module support:

Makefile

all: node_modules lib bin_from_local
	zip -FS -r $(OUT) bin/ lib/ node_modules index.js package.json -x *build*

bin_from_local:
	<use go to compile ./main into bin/>

node_modules:
	docker build -t docker_tmp -f dockerfiles/Dockerfile_node_modules .
	docker cp `docker create docker_tmp`:/user_code/node_modules .
	docker rmi -f docker_tmp

lib: 
	docker build -t docker_tmp -f dockerfiles/Dockerfile_lib .
	docker cp `docker create docker_tmp`:/user_code/lib .
	docker rmi -f docker_tmp

To compile node_modules:

Dockerfile_node_modules

FROM debian:jessie
ADD . /user_code
RUN apt-get update && apt-get install -y --no-install-recommends \
        curl \
        gcc \
        npm \
        build-essential \
    && rm -rf /var/lib/apt/lists/*

RUN curl -sL https://deb.nodesource.com/setup_6.x | bash -  && \ 
    apt-get update && apt-get install -y nodejs

WORKDIR /user_code
RUN npm install --save local_modules/execer

To acquire additional shared objects (.so) files and copy them to lib/

FROM debian:jessie

RUN apt-get update \
    && apt-get install -y --no-install-recommends \
        ca-certificates \
        libc6 \
        libcurl3 \
        libgcc1 \
    && rm -rf /var/lib/apt/lists/*

RUN mkdir -p /user_code/lib && \
    for i in `dpkg -L libc6 libcurl3 libgcc1  | egrep "^/usr/lib/x86_64-linux-gnu/.*\.so\."`; do cp $i /user_code/lib; done

I have read how work this piece of code and it is very powerfu. I would like know how work lifecycle of instance, connection, reuse objects etc.

Thanks in advance

Hello,
Thank you for this wonderful initiative to add Go support to Cloud Functions! Unfortunately, I cannot seem to be able to deploy the example function. It works fine locally, but after uploading the zip file to the new function it just gets stuck during deployment and it eventually gets cut off by the quota limit.
status: { code: 10 message: "Operation interrupted." }

Any ideas of what might be going wrong? Thanks again!
