Heroku Pipelines Review Apps

Heroku Pipelines and Review Apps

Operate multi-environment Heroku delivery flows without collapsing staging, review, and production into one step.

Inspect before changing

Start with:

• heroku pipelines:info <pipeline>
• heroku pipelines:diff -a <upstream-app>
• heroku apps:info -a <app> --json
• local app.json and deploy docs

Use inspection to determine:

• whether a pipeline already exists
• which apps are mapped to which stages
• whether review apps are expected to inherit config or add-ons
• whether promotion is safer than a fresh deploy

Safe workflow

1. identify the pipeline and target stage
2. inspect current stage mappings
3. review app.json before touching review apps
4. confirm whether the user wants promotion or a new deploy
5. apply the smallest safe change
6. verify resulting stage or review-app behavior

Guardrails

Ask for confirmation before:

• creating or destroying a pipeline
• reconnecting apps to different stages
• enabling or disabling review apps with heroku reviewapps:enable -p <pipeline> -a <app> or heroku reviewapps:disable -p <pipeline> -a <app>
• promoting toward production

Treat production promotion as a release action, not as routine inspection.
