How can external libraries from Go can be used in the FAAS product? I.e. running the following function:
package main
import "github.com/sirupsen/logrus"
func Main(args map[string]interface{}) map[string]interface{} {
name, ok := args["name"].(string)
if !ok {
name = "stranger"
}
msg := make(map[string]interface{})
msg["body"] = "Hello " + name + "!"
logrus.Fatal("FAAS can't be used with external Go libraries like github.com/sirupsen/logrus i.e.")
return msg
}
leads to the following error:
stderr: exec__.go:3:8: no required module provides package github.com/sirupsen/logrus; to add it:
stderr: go get github.com/sirupsen/logrus
stderr: failed go build -o /tmp/action/1/bin/exec -ldflags -s -w
stderr: in /tmp/action/1/src
stderr: env {'GOROOT': '/usr/local/go', 'GOPATH': '/tmp/go', 'GO111MODULE': 'on', 'GOCACHE': '/tmp', 'PATH': '/go/bin:/usr/local/go/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin'}
stderr:
stderr: The action did not initialize or run as expected. Log data might be missing.
After adding a go.mod / go.sum, the same error occured.
Help is really appreciated! Thanks in advance.

Hi @ocmer
I ran into the same issue as you, I was able to get it to work by moving the
go.mod
andgo.sum
files into the same directory as themain.go
file.You can see my function here: https://github.com/jonasbn/pxy-redirect-ow-function

Hi there,
I believe that you need to add the
--remote-build
flag to yourdoctl serverless deploy
command in order for this to work.Here is a link to a demo project that utilizes Go modules:

The complete command from the example is:
Best,
