Ingress MetalLB

Out of the box, the MicroK8s distribution of ingress-nginx installed as the MicroK8s addon ingress binds to ports 80+443 on the node's IP address using a hostPort, as we can see here:

microk8s kubectl -n ingress describe daemonset.apps/nginx-ingress-microk8s-controller
Name:           nginx-ingress-microk8s-controller
Selector:       name=nginx-ingress-microk8s

Recon and Attack Vectors from My Logs

This document contains excerpts from my web server logs collected over a period of 7 years that shows various kinds of recon and attack vectors.

There were a total of 37.2 million lines of logs out of which 1.1 million unique HTTP requests (Method + URI) were found.

AWS Lambda JWT authenticaiton

AWS API Gateway has the ability to pre-authenticate connections prior to launching the endpoint, by passing the authorizationToken to a Lambda function. There are clear benefits for simplifying end point security and also a reduction in duplicated code by utilising this feature. However I found the AWS examples were excessively complicated for what should be a very simple task.
So here's my example.

The main concern is that AWS Lambda authentication expects a very specific response and if that response is not given it will throw a 500 error with x-amzn-ErrorType: AuthorizerConfigurationException in the response header if the response object is not exactly as expected.

Usage

I personally use to handle the publishing part of my Lambdas, but I'll include an image of the API Gateway config.

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?
