Once Heroku Toolbelt is installed it requires Pipelines plugin too.
heroku plugins:install heroku-pipelines
You must start with an app to add to the pipeline, although it doesn’t have to be for a particular stage. If you don’t specify
--stage STAGE, the CLI will guess at the appropriate stage, but also let you override the default. The name of the pipeline will be guessed from the app name as well, but can be overridden either by adding the
NAME on the command line, or entering a different name when prompted.
heroku pipelines:create -a example
The target app(s) will be automatically determined by the downstream stage
heroku pipelines:promote -r staging
It is also possible to promote to a specific app (or set of apps)
heroku pipelines:promote -r staging --to my-production-app1,my-production-app2
A complete list of Pipelines commands with usage details is available in the console
heroku help pipelines
