Fly launch sequence

[ndrean]

This app uses 2 databases: PostgreSQL & SQLite.

1️⃣ "pre-launch" to auto-detect Postgres: this will provision a PG app

fly launch --no-deploy -y

2️⃣ Setup volumes

Check if the Pg app is created:

fly pg list

NAME           	OWNER   	STATUS  	LATEST DEPLOY
liveview-pwa-db	personal	deployed

Set LOGICAL to PG conf:

fly pg config update --wal-level logical -a liveview-pwa-db -y

❗️ You get by default a "dev" machine with 256MB. You may need to upgrade the PG machine for a 512MB one. I got teh machine_id (2874469f1dde98) from the Fly desktop:

fly machine update 2874469f1dde98 --vm-memory 512 -a liveview-pwa-db

Set a volume to persist the SQLite file:

fly volumes create db --size 1 --region bog -y

3️⃣ Reconfigure "fly.toml"

❗️The "fly.toml" is updated by Fly. Paste the following (the IPV6 ERL flags are important):

# [deploy]
#   release_command = '/app/bin/migrate'

[env]
DATABASE_PATH = '/data/db/main.sqlite3'
MIX_ENV = 'prod'
PHX_HOST = 'liveview-pwa.fly.dev'
PORT = '8080'
ECTO_IPV6 = 'true'
ERL_AFLAGS = '-proto_dist inet6_tcp'

[[mounts]]
source = 'db'
destination = '/data'
auto_extend_size_threshold = 80
auto_extend_size_increment = '1GB'
auto_extend_size_limit = '10GB'

🚀 Deploy
