Notes for deploying to AWS

Whenever you install a new package into the virtualenv, update requirements.txt:

pip freeze | grep -v pkg-resources > requirements.txt

git commit to the state that you want to deploy, then eb deploy.

Environment variables

These contain sensitive information. I've stored them in

pass Servers/aws/blackjack-web-deb/env

You can view them with eb printenv

PostgreSQL

The credentials are stored in pass.

Upon changing the models in the code, you need to update the schema in the database. Create the migrations:

flask db migrate -m "description of changes made"

To apply the migrations to the local test database, simply do:

flask db upgrade

To apply the migrations to the real database:

./db-tunnel.sh &
sleep 3
bash
source bj-venv/bin/activate
source <(pass Servers/aws/blackjack-web-dev/postgres-env)
flask db upgrade
exit
kill %1

To connect to the remote DB manually, run the above commands until flask db upgrade. At that point, run the pass command to get access to the password. Copy it. Then you can run this command and paste the password when prompted.

psql -d $RDS_DB_NAME -h 127.0.0.1 -p $RDS_PORT -U $RDS_USERNAME
Password for user [...]:
