Heroku Review Apps

Creating a review app

1. Login to the heroku dashboard

2. Go to the wazimap pipeline

3. Click "Create review app" for your pull request

Find the URL to the deployed review app in the pull request or by clicking "View app" in heroku.

Migrations and demodata are only loaded when the app is created. If you need to recreate the database, destroy the app and recreate it.

Connecting a netlify frontend deploy preview to backend review app

• Copy link for frontend review app ex: deploy-preview-542--wazimap-staging.netlify.app

• Add it to the configuration in profiles for the backend review app and save
• Go to Ui deploy preview add ?dev-tools=true to enable dev tools and add deploy-preview-542--wazimap-staging.netlify.app to Hostname and backend review app url to Api url https://wazireview.herokuapp.com and enter

Creating staging apps in heroku

This is probably not helpful any more now that real review apps work again, but we're leaving this here for now in case it's needed.

We were creating "review apps" in the staging "stage" of the wazimap pipeline in heroku while heroku review apps were not working due to the exfiltration of github oauth keys.

Create a new app

We name apps according to the pull request number, e.g. wazimap-pr-1234 for PR #1234

Steps for creating an app via CL

• heroku login

In the project directory (to update your project git remotes):

• heroku apps:create wazimap-pr-1234 --remote heroku-pr-1234

• heroku pipelines:add wazimap --app wazimap-pr-1234 --stage staging

Steps for creating an app via GUI

• Login into Heroku Web

• Go to wazimap pipeline

• After opening wazimap pipeline there is an option to add new staging app
• Open the newly created app and go to deploy
• Copy command to add remote for existing repo and paste it to your command line inside wazi backend repo to add this app as heroku remote

Steps for setting up the stack

• heroku stack:set container --app wazimap-pr-1234

• Adding Addons:
