Converting JSON to OpenAPI / Swagger spec

Exploring tools that allow converting a JSON response automagically into an OpenAPI / Swagger spec.

Test JSON Response

I'm buiding a command line tool in Go that has an option to install itself as a service on Windows, which it needs admin rights for. I wanted to be able to have it reliably detect if it was running as admin already and if not, relaunch itself as admin. When the user runs the tool with the specific switch to trigger this functionality (-install or -uninstall in my case) they are prompted by UAC (User Account Control) to run the program as admin, which allows the tool to relaunch itself with the necessary rights.

To detect if I was admin, I tried the method described here first:
https://coolaj86.com/articles/golang-and-windows-and-admins-oh-my/
This wasn't accurately detecting that I was elevated, and was reporting that I was not elevated even when running the tool in CMD prompt started with "Run as Administrator" so I needed a more reliable method.

I didn't want to try writing to an Admin protected area of the filesystem or registry because Windows has the ability to transparently virtualize those writes

Be Careful with Table Driven Tests and `t.Parallel()`

We Gophers, love table-driven-tests, it makes our unittesting structured, and makes it easy to add different test cases with ease.

Let’s create our table driven test, for convenience, I chose to use t.Log as the test function. Notice that we don't have any assertion in this test, it is not needed to for the demonstration.

func TestTLog(t *testing.T) {
	t.Parallel()

Deploying Keycloak to AWS

The objective of this guide is to deploy Keycloak to AWS in a minimally complex way for testing and discovery purposes. This means using the standalone build of Keycloak backed with Hibernate H2. The result is not a production ready system. It won't scale, it won't survive significant load, it can't be clustered.

Mostly this Gist is a distillation of the Keycloak Server Installation guide for a specific use case: to spin up a quick and dirty Keycloak instance for testing and experimenting.

Steps

Spin up and configure a Ubuntu AMI
Install and configure Keycloak with an SSL cert
