notplants 101ffe1964 fix(db): make pg_upgrade migration idempotent & crash-safe

The postgres major-version migration in the db entrypoint was not safe to
re-run. If the container was killed mid-migration it could crash-loop forever
("mkdir: cannot create directory .../old_data: File exists") or silently initdb
a fresh empty cluster over the live data once PG_VERSION had been moved out of
$PGDATA but before the in-progress marker was written.

Replace the marker file with a state-driven guard keyed on the scratch dirs:
empty old_data/new_data means the run was interrupted before any data moved, so
discard and retry (idempotent); non-empty means data may only live there, so
stop for manual recovery. Bump DB_ENTRYPOINT_VERSION v1->v2 so swarm picks up
the new (immutable) config.

Basic usage

Set up Docker Swarm and abra
Deploy coop-cloud/traefik
abra app new discourse --secrets (optionally with --pass if you'd like to save secrets in pass)
abra app config YOURAPPDOMAIN - be sure to change $DOMAIN to something that resolves to your Docker swarm box
abra app deploy YOURAPPDOMAIN
Open the configured domain in your browser to finish set-up

To add a new admin user

Login to the instance abra app run APPNAME app sh
cd /opt/bitnami/discourse
RAILS_ENV=production bundle exec rake admin:create and follow prompts.

Install plugins

Login to instance abra app run APPNAME app sh
cd /bitnami/discourse/plugins/
git clone plugin.git for example https://github.com/discourse/discourse-openid-connect.git
abra app restart YOURAPPDOMAIN app

Events / calendar plugin

We've had some luck running discourse-events.

Setup Notes

Until issue #1 is fixed, the default user is user and the default password is bitnami123

Postgres major version upgrades

Welcome to hell.

abra app run YOURAPPDOMAIN db pg_dumpall -U discourse | gzip > YOURAPPDOMAIN_db_DATE.sql.gz
abra app volume ls YOURAPPDOMAIN, find the name of the Postgres data volume
scp the backup to your VPS
abra app undeploy YOURAPPDOMAIN
abra app volume rm YOURAPPDOMAIN, choose the Postgres data volume
abra app deploy YOURAPPDOMAIN, then abra app undeploy YOURAPPDOMAIN
ssh to the VPS, run (replacing 13-alpine with the new Postgres version) docker run -v YOURDATAVOLUME:/var/lib/postgresql/data -e POSTGRES_HOST_AUTH_METHOD=trust -it postgres:13-alpine
In another SSH session on the server, run docker ps to find the ID of the new Postgres container, then docker exec -it CONTAINERID bash
In the shell you just launched, run dropdb -U discourse discourse, then createdb -U discourse discourse, then Ctrl+D or run exit
In the second SSH session, run zcat YOURAPPDOMAIN_db_DATE.sql.gz | docker exec -it CONTAINERID psql -U discourse
Exit the second SSH session
Back in the first SSH session, Ctrl+C to shut down the database
abra app deploy YOURAPPDOMAIN
