heroku psql -a sapling-planning

CREATE SCHEMA agile AUTHORIZATION <username>;
ALTER ROLE <username> SET search_path TO agile;

Deploy and configure the server:

heroku config -a sapling-planning

DATABASE_URL: postgres://<username>:<password>@ec2-<ip>.compute-1.amazonaws.com:5432/<database>

Generate keypair for JWT token signing:

openssl genrsa -des3 -out private.pem 2048
openssl rsa -in private.pem -outform PEM -pubout -out public.pem

# Java requires keys in pkcs8 format
openssl pkcs8 -topk8 -inform PEM -outform PEM -in private.pem -out private-pkcs8.pem -nocrypt

heroku config:set PROPS_JWT_PRIVATE_KEY="$(cat private-pkcs8.pem)" PROPS_JWT_PUBLIC_KEY="$(cat public.pem)" -a sapling-planning

Stay within free tier memory quota:

heroku config:set JAVA_OPTS="-XX:+UseSerialGC -Xmx250M -Dserver.tomcat.max-threads=5" -a sapling-planning

Check out the workflow configuration as well. You'll want HEROKU_API_KEY in the repository's secrets.
