Learn Go in ~5mins

This is inspired by A half-hour to learn Rust and Zig in 30 minutes.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

Kubernetes on DigitalOcean with CoreOS

Let's look at an example of how to launch a Kubernetes cluster from scratch on DigitalOcean, including kubeadm, an Nginx Ingress controller, and Letsencrypt certificates.

Overview

Environment

We'll be creating a four-node cluster (k8s-master, k8s-000...k8s-002), load balancer, and ssl certificates.

1. Install Kubernetes

Scenario

• Django 1.9 application with two databases:
  • Legacy database with readonly access via unmanaged models. Both Django models (models.py) and related migrations have "managed" set to False
    • 'managed': False
  • Default database holding django specific tables (e.g. auth_user, django_content_type, etc)

Testing Woes

• For testing I want to re-create the legacy database tables. In other words, during python manage.py test, tell Django to set "managed" to True
  • There are several excellent blog posts on how to set "managed" to True during tests:

Select database based on URL variable

Inspired by this Django snipped:

It's assumed that any view in the system with a cfg keyword argument passed to
it from the urlconf may be routed to a separate database. for example:
