Migrate to Heroku

Setup Heroku account

First make sure you have an Heroku account, if you don't, go to https://signup.heroku.com

Installing CLI

Next let's install the Heroku CLI

brew install heroku/brew/heroku

Now we can login in the CLI

heroku login

Enter your Email and password.

Create your application

Using the CLI we can create our application like this

Add a Profile and .swift-version, make sure you are in your project folder

echo "web: Run --env production --hostname --port $PORT" > Procfile
echo "5.1.3" > .swift-version

Now let's add the files to git

git add .
git commit -am "Setup Heroku deployment"

Now we can create our app and deploy it

heroku apps:create your-application-name --buildpack vapor/vapor
git push heroku master

heroku ps:scale web=1

heroku apps:create can take a --region eu if you want your app in EU rather than the US.

Create a Postgres database

Create a postgres database on Heroku

heroku addons:create heroku-postgresql:<PLAN_NAME>

To create a free plan database, use

heroku addons:create heroku-postgresql:hobby-dev

Migrate data from Cloud 2 to Heroku

Start by finding the credentials, these are exposed in the dashboard, under your application, and the database, click the 3 dots, and connection details. Copy the URL and use it in the next step

Dump your database

Let's start by exporting data to a file.

pg_dump --dbname=<CONNECT-URL> > /tmp/my-db.sql

Import the file into Heroku

Find the credentials you can get them by running this command

heroku pg:credentials:url DATABASE

Now use the credentials in the command below

psql -h <HOSTNAME> -U <USER> -W -d <DATABASE> -f /tmp/my-db.sql

You should now be able to use your application on Heroku.
