JetStream Stream Sharing

This is an incremental tutorial on how to share JetStream assets between accounts. The options are not going to be fully explained unless they are vital. The tools used are nats cli and nsc, and both have excellent --help.

Note that this tutorial is expected to be followed in sequence.

Prerequisites

Understand imports and exports and JWT

I get asked pretty regularly what my opinion is on merge commits vs rebasing vs squashing. I've typed up this response so many times that I've decided to just put it in a gist so I can reference it whenever it comes up again.

I use merge, squash, rebase all situationally. I believe they all have their merits but their usage depends on the context. I think anyone who says any particular strategy is the right answer 100% of the time is wrong, but I think there is considerable acceptable leeway in when you use each. What follows is my personal and professional opinion:

PostgreSQL is Enough

Background and Cron Jobs

ANSI Escape Sequences

Standard escape codes are prefixed with Escape:

Ctrl-Key: ^[
Octal: \033
Unicode: \u001b
Hexadecimal: \x1B
Decimal: 27

Last tested version: 5.7.20

0. Preparation

Make sure LXC has more than 12GB, otherwise Unifi fails to start!
