Cannot deploy sample GOLang application to Heroku

Question

I tried deploying the sample GO application to Heroku listed here

But when I run the command:

git push heroku master

I get the following error:

Counting objects: 28, done.

Compressing objects: 100% (21/21), done. Writing objects: 100% (28/28), 3.08 KiB, done. Total 28 (delta 6), reused 0 (delta 0)

To [email protected]:mysterious-refuge-1227.git ! [remote rejected] master -> master (pre-receive hook declined) error: failed to push some refs to '[email protected]:mysterious-refuge-1227.git'

The sample code might be out-of-date so I created a simple hello world GO App but from the same git push command I got the following error:

Counting objects: 10, done.
Compressing objects: 100% (8/8), done.
Writing objects: 100% (10/10), 1.16 MiB | 690 KiB/s, done.

Any ideas on how I can resolve this issue?

Here is my system info:

• GoLang version: go version go1.1 linux/386
• Kubuntu version: 12.10

I suspect your original error is because you created the application with heroku create. You're using Go, which is supported through a buildpack, so you should create the application with something like heroku create -b https://github.com/kr/heroku-buildpack-go.git. I believe the demo app makes the same mistake - my fork fixes it - and I've submitted a pull request too.
