Heroku How to push different local Git branches to Heroku master

Question

Heroku has a policy of ignoring all branches but  master    While I m sure Heroku s designers have excellent reasons for this policy  I m guessing for storage and performance optimization   the consequence to me as a developer is that whatever local topic branch I may be working on  I would like an easy way to switch Heroku s master to that local topic branch and do a  git push heroku -f  to over-write master on Heroku   What I got from reading the  Pushing Refspecs  section of http   progit org book ch9-5 html is  git push -f heroku local-topic-branch refs heads master  What I d really like is a way to set this up in the configuration file so that  git push heroku  always does the above  replacing local-topic-branch with the name of whatever my current branch happens to be   If anyone knows how to accomplish that  please let me know   The caveat for this  of course  is that this is only sensible if I am the only one who can push to that Heroku app repository  A test or QA team might manage such a repository to try out different candidate branches  but they would have to coordinate so that they all agree on what branch they are pushing to it on any given day   Needless to say  it would also be a very good idea to have a separate remote repository  like GitHub  without this restriction for backing everything up to  I d call that one  origin  and use  heroku  for Heroku so that  git push  always backs up everything to origin  and  git push heroku  pushes whatever branch I m currently on to Heroku s master branch  overwriting it if necessary   Would this work     remote  heroku       url   git heroku com my-app git     push    refs heads   refs heads master   I d like to hear from someone more experienced before I begin to experiment  although I suppose I could create a dummy app on Heroku and experiment with that   As for fetching  I don t really care if the Heroku repository is write-only  I still have a separate repository  like GitHub  for backup and cloning of all my work   Footnote  This question is similar to  but not quite the same as Good Git deployment using branches strategy with Heroku

When using a wildcard  it had to be present on both sides of the refspec  so  refs heads   refs heads master will not work  But you can use  HEAD refs heads master   git config remote heroku push  HEAD refs heads master   Also  you can do this directly with git push   git push heroku  HEAD master git push -f heroku HEAD master

You should check out heroku san  it solves this problem quite nicely   For example  you could   git checkout BRANCH rake qa deploy   It also makes it easy to spin up new Heroku instances to deploy a topic branch to new servers   git checkout BRANCH   edit config heroku yml with new app instance and shortname rake shortname heroku create deploy   auto creates deploys and migrates   And of course you can make simpler rake tasks if you do something frequently

For me  it works   git push -f heroku otherBranch master      The -f  force flag  is recommended in order to avoid conflicts with other developers    pushes  Since you are not using Git for your revision control  but as a transport only  using the force flag is a reasonable practice    source  - offical docs

The safest command to push different local Git branches to Heroku master   git push -f heroku branch name master   Note  Although  you can push without using the -f  the -f  force flag  is recommended in order to avoid conflicts with other developers    pushes
