在Golang应用程序中使用Heroku Scheduler附加组件

Question

I can't figure out how to use the Heroku Scheduler add-on with Go.

I would like run a separate Go file periodically, but I can find the command to achieve that.

From Heroku's doc (https://devcenter.heroku.com/articles/scheduler), if the app is not a Rails app, I should use a ruby script. But I don't know how to run a Go file from there.

Answer 1

I ended up forking the same main function used by my web dyno:

func main () {
    if len(os.Args) >= 2 && os.Args[1] == "my_job_param" {
       // Execute job.
    } else {
       // Set up my web server with port, router, etc.
    }
}

Then, in the Scheduler add-on, I just call: my-app-name "my_job_param". It's pretty hacky, but I wanted to find a solution using the Scheduler add-on.
