How to kill an heroku build that is in progress?

Question

I accidentally pushed a build that does an npm install in the postinstall script. This has led to my heroku app being stuck in an infinite install loop. I searched the heroku documentation on how to kill builds but came up blank. The closest thing I found was https://help.heroku.com/Z44Q4WW4/how-do-i-stop-a-release-phase and I tried killing as per those instructions but my build won't die :(

Answer 1

The heroku-builds CLI plugin (heroku plugins:install heroku-builds) has a command which will stop a running build:

$ heroku builds:cancel -a your-app-name

All builds will time out too after a time that can go between 15 minutes to 1 hour.

this workd but one needs to heroku plugins:install heroku-builds before, just like explained here https://mcmap.net/q/293393/-how-to-kill-an-heroku-build-that-is-in-progress – Indogermanic

what if app is a review app? – Malnourished

Review apps are apps like any other, with their app name being the part of the hostname before .herokuapp.com. So you can kill them exactly the same way. – Reuven

Answer 2

If you have a build going into production right now and need to stop it quickly:

heroku plugins:install heroku-builds
heroku builds:cancel -a YOUR_HEROKU_APP_NAME

Perfect - I needed that quick cancel! – Berkeley

This is so amazing! fast and clean. – Majolica

Once you are logged in, just heroku builds:cancel should do it - for the most recent 🏃🏾‍♂️ build at least. – Jello

Answer 3

To view all builds run the following in your terminal:

heroku builds -a YOUR_APP_NAME

To cancel a specific (pending) build:

heroku builds:cancel -a YOUR_APP_NAME HEROKU_BUILD_ID

Update (4th July 2020):

If you see the message Warning: builds is not a heroku command, run heroku plugins:install heroku-builds and try again.

Arguably the best answer since it lets you cancel a specific build – Argon
