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 has a builds:cancel command which will stop a running build.

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

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

Answer 3

To view all builds:

heroku builds -a YOUR_APP_NAME

To cancel a specific (pending) build:

heroku builds:cancel -a YOUR_APP_NAME HEROKU_BUILD_ID
