bitbucket private repository on heroku

Question

I have a rails app which requires a gem. I host this gem on bitbucket in a private repository.

In my Gemfile I added the gem like following:

gem "my-gem", :git => "[email protected]:my-username/my-gem.git", :branch => 'master'

I want to deploy my rails app on heroku with

git push heroku master

Now I always get following error

Fetching [email protected]:my-username/my-git-repo.git
Host key verification failed.
fatal: The remote end hung up unexpectedly

I understand the error, because the repository is set to private. But how can I solve this problem?

I already read this question: Deploying to Heroku using git on bitbucket, but I don´t really get the answer :)..

Answer 1

Bitbucket allows for HTTP basic auth on repository URLs similar to github. Specify the URL for the gem as https://username:[email protected]/username/gemrepo.git.

It does mean having your username and password in your Gemfile, which itself is version controlled, and that's not a good practice, but on the other hand that's what Heroku recommends, so...

Answer 2

The proper way to achieve this is using bundle config, which saves the configuration on your home directory .bundle/config so it stays outside the repo.

bundle config bitbucket.org user:pwd

And then on Heroku you have to set a simple configuration in a special way:

heroku config:set BUNDLE_BITBUCKET__ORG=user:pwd

And in your Gemfile you just use the URL without the credentials.

gem 'gemname', git: "https://bitbucket.org/User/gemname.git"
