Kubernetes - Deploying Pod workloads and running Docker images with a load balancer

-


In this example I go over how to deploy manageable pod workloads and run Docker images with a load balancer using Kubernetes. I first configured a cluster with 3 nodes and connected to it via SSH using the command line interface. I set up the appropriate yaml file and then checked to see that my nodes were up.

Load averages for the virtual machines
Kubernetes with Digital Ocean also gives a lot of insights into the network management which becomes more important as sites scale since the purpose is to have an efficient infrastructure for the websites I am creating and deploying. I will go over the intricacies in subsequent posts but for now let it suffice that from this point a broad variety of workloads can be employed from cron jobs to all sorts of daemon sets.

Now with my nodes created I created a cluster
At this point I created the nodes that formed the cluster. Then provisioned the clusters to run an example image with a load balancer to funnel traffic from different regions to different nodes with the same image running. Here below you can see the file where I configured the server protocol, ports, and everything else.




Now here we have NGINX serving up the content appropriately and it is time to customize further but the base is here and there is a solid foundation with the pod workloads running Docker images with a load balancer for efficiency.

Automated Exploitation of a Bluetooth vulnerability that leads to 0-click code execution

This blog post covers an interesting vulnerability that was just discovered earlier this year and an open source free tool that was created to automate testing for this vulnerability in Bluetooth devices.  I will preface this with the warning that this is of course done in my personal testing lab environment with my own devices for learning and demonstration purposes. I am in no way encouraging that these tools, snippets of code or techniques be used maliciously as there can be very serious legal consequences for those that use these hacking tricks nefariously. However, in a personal testing lab environment I think this is great for learning and allows someone to quickly be able to confirm or deny if their personal devices are truly standing up to the Bluetooth CVE of CVE-2023-45866 . CVE-2023-45866 is described as an issue where the " Bluetooth HID Hosts in BlueZ may permit an unauthenticated Peripheral role HID Device to initiate and establish an encrypted connection, and accept...

Raspberry Pi WiFi Honeypot 🍯

This was a fun project to work on and build out. I learned a few new interesting tricks along the way. I started with this tutorial from 2013 by Andy Smith . However, a few things have changed with hostapd that I had to figure out through debugging. Also, the configuration of the nginx server as well as dnsmasq were slightly different for me using the new Raspbian Buster for Raspberry Pi 4.  This should save you some time if you follow my trick tips later on in the article that I found by searching through various message boards and googling error messages as I did debugging to get this working properly. I have gone over setting up nginx servers in previous articles so if you need help with getting started these may be helpful. So first things first. I started with a canakit and assembled the raspberry pi with the appropriate heat sinks and a little fan set to a standard speed. The speed is adjusted by how you install the wiring. If you haven't done this before you can follow the ...
