64bit Amazon Linux 2 v3.4.0 running Ruby 3.0

This requires RAILS_ENV, and RAILS_MASTER_KEY and database creds to be set as env vars

If you havent already run 
`rails credentials:edit` to create your master key. Then `rails credentials:edit --environment=staging` to set your staging env creds. 

Now export:
export RAILS_MASTER_KEY="545b...530";
export ENVIRONMENT=staging;
export RAILS_ENV=staging;
export DATABASE_HOST=yourdbhost.us-east-1.rds.amazonaws.com;
export DATABASE=jumpstart;
export DATABASE_USERNAME=jumpstart;
export DATABASE_PASSWORD=jumpstarttest;
export AWS_ACCESS_KEY_ID=your_aws_key;
export AWS_SECRET_ACCESS_KEY=your_aws_secret_key;

zip up your app and deploy 

git ls-files | zip app.zip -@
eb_deploy -p app.zip -e dev

The aws solution stack version changes frequently so if this fails initially it will print out available stack names copy one of those then go to config/eb_deployer.yml and look for solution_stack and paste

Run this command in your Rails app directory in the terminal:

rails app:template LOCATION="https://railsbytes.com/script/zOvsLn"
