Some important notes

The latest Docker Compose uses some parsing under-the-hood that makes secrets stored in .env files break. So any $$ is actually a single $ being escaped. Annoying & something that must be documented!

Commands

Build and start everything:

sudo -E docker compose -f docker-compose.prod.yml up -d --build

Stop all services:

sudo -E docker compose -f docker-compose.prod.yml down

Export updated requirements.txt, necessary whenever dependencies changed:

poetry export -f requirements.txt --output requirements.txt

Redeploy Django app:

sudo -E docker compose -f docker-compose.prod.yml up -d --force-recreate --build web

Manual management commands

sudo -E docker compose -f docker-compose.prod.yml exec web python manage.py migrate --noinput

sudo -E docker compose -f docker-compose.prod.yml exec web python manage.py collectstatic --no-input --clear

Copying config files

Retrieve from server:

scp -r [email protected]:/home/princeton/princetonpy.org/prod/{.env.prod.web,.env.prod.aws,.env.prod.db,.env.prod.nginx,.env.prod.proxy-companion} .

Transfer to server:

scp -r $(pwd)/{.env.prod.web,.env.prod.aws,.env.prod.db,.env.prod.nginx,.env.prod.proxy-companion} [email protected]:/home/princeton/princetonpy.org/prod
scp -r $(pwd)/{.env.staging.aws,.env.staging.db,.env.staging.nginx,.env.staging.web,.env.staging.proxy-companion} [email protected]:/home/princeton/princetonpy.org/staging

Importing users from CSV

Make sure file is copied to mounted app directory:

scp -r princetonpy_subscriptions.csv user@host:/path
sudo -E docker compose -f docker-compose.prod.yml run web sh
python manage.py subscriptions import ./princetonpy_subscriptions.csv

Access DB

sudo -E docker compose -f docker-compose.prod.yml exec db psql -U postgres -W princetonpy_prod
# select * from django_site;

Working with backup files

sudo -E docker compose -f docker-compose.prod.yml run cron ls -la /prod_backup/subscribers
sudo docker container ls
# get hash from CONTAINER ID column
sudo docker cp fc95ab44a580:/prod_backup .

Manual Django shell updates

In server:

sudo -E docker compose -f docker-compose.prod.yml run web sh

In container:

python manage.py shell

And then in Django shell:

import dateutil
from datetime import datetime

from meetings.models import Meeting

delta = dateutil.relativedelta.relativedelta(months=2)
before_date = datetime.now(tz=dateutil.tz.gettz("America/New_York")) - delta

# returns queryset
meeting_qs = Meeting.objects.filter(date__lte=before_date)
meeting_qs.update(tba=False)

Backup DB

docker compose exec -t db pg_dumpall -c -U postgres > dump_`date +%d-%m-%Y"_"%H_%M_%S`.sql

Use this one:

docker compose exec -t db pg_dump -U postgres princetonpy_prod > dump_`date +%d-%m-%Y"_"%H_%M_%S`.sql

To restore

Rename dump[...].sql.

May have to manually rename princetonpy_prod to princetonpy:

cat dump_27-11-2022_16_28_02.sql | psql -U postgres -d princetonpy
