How to kill an heroku build that is in progress?
HerokuHeroku CliHeroku Problem Overview
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 :(
Heroku Solutions
Solution 1 - Heroku
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
Solution 2 - Heroku
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.
Solution 3 - Heroku
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.
