Heroku

1 - Initialize Heroku on your machine

heroku login
heroku container:login

2 - Create a new project

heroku create <project-name>

Important If you are deploying a docker app, you should set the stach to container at the creation time or, if you already have created the app, set it later:

## Define container stack on creation
heroku create --stack=container

## Set the stack of a already existent app
heroku stack:set container

Create a "heroku.yml" file with the following content:

build:
  docker:
    web: Dockerfile

3 - If you need to set some env vars:

Use single quotes

heroku config:set API_URL='http://localhost:5000/'

Deploying

When deploying your app to Heroku, you can choose one of the three methods below:

Heroku Git

If you already have created a Heroku App...

Add the Heroku remote and push to it's master branch.

heroku git:remote -a <project-name>
git push heroku master

If you want to push another branch to heroku master...

git push heroku <local-branch>:master

GitHub

This option allows you to deploy, automatically also, via GitHub. To do so, just follow the steps...

Container Registry

heroku container:push web
heroku container:release web
heroku open
