How to deploy a Rails 7.1 app with Postgres and Kamal on a single server

I think you have looked at the tutorial from Mr. Heinemeier Hansson at least once or twice and have a similar setup.

rails new kamal_pg --css tailwind --skip-test --database=postgresql

cd kamal_pg

-- show running queries (pre 9.2)
SELECT procpid, age(clock_timestamp(), query_start), usename, current_query 
FROM pg_stat_activity 
WHERE current_query != '<IDLE>' AND current_query NOT ILIKE '%pg_stat_activity%' 
ORDER BY query_start desc;

# Test the result of config.assets.precompile
#
# Check which files will be regarded as "manifests" and thus precompiled and be
# available for standalone use via the /assets/<asset> URL when in production.
# Execute this code in your Rails console.

# First, you'll probably be in development mode, so add here your
# additional production precompile patterns you want to test against.
precompile = Rails.configuration.assets.precompile + [/^.+\.css$/, 'active_admin.js']

Configure Postgres

• Update pg_hba.conf (most likely in /etc/postgresql/9.4/main) with -
  • host all all 0.0.0.0/0 trust
• Update postgresql.conf to use listen_addresses = '*'
• Be sure to sudo service postgresql restart

Configure Vagrant

Walmart Drop Ship Vendor Supplier DSV Carrier Method Codes

As part of the Walmart DSV API, there are carrier method codes in the order xml, but the only documentation I found was in this PDF. That document is referenced from Supplier Help.

That PDF file is of course not easily consumable and it was a wicked pain in the ass to get the data out of there. But, it's done now, and if you happen to find this file I hope I saved you some time.
