在Heroku上运行Go应用

Question

I'm trying to follow the tutorial at https://mmcgrana.github.io/2012/09/getting-started-with-go-on-heroku. Initially everything seems to work:

ceiroa-ltm:my_heroku_app ceiroa$ heroku create -b https://github.com/kr/heroku-buildpack-go.git

However, no dynos are spinned:

ceiroa-ltm:my_heroku_app ceiroa$ heroku ps
ceiroa-ltm:my_heroku_app ceiroa$ 

And the app gives an error:

What am I doing wrong?

Answer 1

I tried a bunch of things that didn't work:

1. downgrade go version (to match the one defined in https://github.com/kr/go-heroku-example/blob/master/Godeps/Godeps.json)
2. move from default Eclipse Go structure to one without src, bin, or pkg inside project
3. use hyphens instead of underscores (for project name and in Procfile and Godeps.json)
4. define full identifier in Godeps.json

At the end and started from scratch again, creating the project from the command line instead of from Eclipse, and this worked.

From the things above, I can rule out #1 and #4 as fixes, as I'm back to using the same config I initially had.

Another thing that was throwing me off was references to ".godir" in different websites and posts. I don't know what this file used to be used for, but it doesn't seem necessary any more.

I'm going to point to Eclipse and its Go plugin as the culprits, for now.
