deploy branches to heroku automatically

[chadwhitacre]

We need this to turbo-charge our development workflow (@corytheboyd and @warreng called it; props). The idea is that any branch in GitHub gets its own public deployment, with its own database with fake data. This should be a subcommand of gittip.

Note that Heroku deploys master, so you have to do git push -f heroku HEAD:master.

Or possibly git push staging staging:master.

[chadwhitacre]

It's git push <remote-repo> <local-branch>:master.

Yeesh. I just hand-rolled another Gittip instance on Heroku. That was ... something that could be optimized.

I wonder whether we can leverage Heroku buildpacks to do this. Circle back here after #1257.

Dropping from Infrastructure. This is advanced infrastructure.

@clone1018 found http://prune.io/ for this. IRC

Assuming each branch gets deployed to a brand new Heroku instance, is there a limit to the number of free Heroku instances you can have?

[rummik]

@seanlinsley I'm pretty sure it's fine so long as you're not using the extra instances to get around paying for extra dynos

+1 from @techtonik at #3718 (comment).

Should we have a dev.gratipay.com with the WIP site version that is automatically pushed on commits from master?

For each new GitHub pull request (“PR”), Heroku will spin up a disposable “Review App” with a unique URL for the development team to review and test. Now, instead of guessing what the new code might do, reviewers — including designers, testers, and PMs — can receive a link and actually try it out in a browser, before the code reaches staging or production environments.

Today, we are happy to announce the graduation of Heroku Review apps from an exceptionally popular beta to being generally available to all Heroku users.

Review apps are the instant, disposable Heroku app environments that can spin up automatically with each GitHub pull request. They allow developers and their teams to automatically build and test any pull request, updated at every push, at a temporary, shareable URL. When the pull request is closed or merged, the Review app is deleted. GitHub users are notified of all this, right in the pull request web interface.

The page in the last comment seems to be pulled back. I guess the service is still beta. Will it be free for our purpose?

[chadwhitacre]

Looks like they have a broken redirect on the blog post. Here's the correct link: https://blog.heroku.com/heroku-review-apps-ga.

I've updated the link in my comment.

As the issue isn't user-oriented, reticket to inside.
