Copy postgres files for container to use + create log file:

cp ~/.pgpass ./gogensite
cp ~/.pg_service.conf ./gogensite
touch ./gogensite/error.log

Ensure Postgres server is configured to allow connections from all hosts/docker containers. Done in Config file /etc/postgresql/{Version}/main/postgresql.conf

Also edit (/etc/postgresql/{Version}/main/pg_hba.conf) and include the line to allow docker to connect to postgres + allow gogen script to access postgres:

host all all 10.0.0.0/0 scram-sha-256
local all postgresmd5 md5

.env file structure:

SECRET_KEY=<SECRET_KEY>
PG_PUZZLE_DBNAME=<PG_PUZZLE_DBNAME>
PG_PUZZLE_USER=<PG_PUZZLE_USER>
PG_PUZZLE_PASSWORD=<PG_PUZZLE_PASSWORD>
PG_DEV_DBNAME=<PG_DEV_DBNAME>
PG_TEST_DBNAME=<PG_TEST_DBNAME>
PG_USER=<PG_USER>
PG_PASSWORD=<PG_PASSWORD>
PG_HOST=<PG_HOST>
PG_PORT=<PG_PORT>

For tests:

sudo apt-get install chromium-browser

This should automatically install the browser as well as the driver. (ensure snap is installed) Check that /snap/bin/chromium.chromedriver exists.
