Using OpenTofu ephemeral resources to create a SSH tunnel to a Postgres DB

Create the docker-compose.yaml and start the containers. To make this work you need a public ssh key to be injected into the "bastion" container.

SSH_PUBLIC_KEY=`cat ~/.ssh/id_rsa.pub` podman compose up

Save the name of the database container:

export DB_CONTAINER_NAME=$(podman ps --format '{{.Names}}'| grep "db-1")
