How to Install Grafana, Prometheus and Node Exporter on Debian 12

Prometheus is a software package that can watch and collect statistics from many different k8s pods and services. It then provides those statistics in a simple html/text format, often referred to as the "scraper page", meaning that it scrapes the statistics and presents them as a simple text-based web page. Grafana is a data visualization tool, which contains a time series database and graphical web presentation tools. Grafana imports the Prometheus scraper page statistics into it's databas

DevOps Beginners (What to Learn?)

I am on this path myself but I asked if I could have a map of the path I should follow to get caught up with where the DevOps world is today and I was told... Learn a programming language. Python is a great one to learn and one of the easiest and most powerful Get comfortable with linux.  Most everything DevOps is built on an instance of linux because seriously, windows is old news.  Trying to use linux as your default workspace will help you a lot to get involved with the unix ec

Container Orchestration

For high availability you need to utilize a "Container Orchestration" like Docker Swarm (easy to setup and get started, limited: lacks autoscaling feature for complex applications) kubernetes (difficult to setup and get started, many advanced features, supported by multiple vendors, more so than the other two. Also supported on all cloud providers, also the kubernetes project is the top ranked project on Microsofts GitHub) MESOS (difficult to setup and get started, many adv

Kubernetes Ingress Controllers

A Kubernetes Ingress is a set of rules that exposes cluster services externally. For an Ingress to handle traffic and function, Kubernetes uses an Ingress controller resource that implements Ingress rules within the cluster. Unlike other controllers, Kubernetes does not start an Ingress controller automatically. Rather, it lets administrators choose one or multiple Ingress controllers within a cluster. While Kubernetes maintains the NGINX (Kubernetes managed), AWS Load Balancer Controller,

Docker is the most popular and widely used container runtime. It enables you to package and run your applications in isolated containers in a single server or cluster of Linux servers orchestrated by Kubernetes and similar tools. Docker Components / Terminologies Below are commonly used terminologies in Docker ecosystem. Docker daemon: This is also called Docker Engine, it is a background process which runs on the host system responsible for building and running of containers.

Docker Desktop

Very easy to install Docker Desktop on the Mac and loving it.  I'm learning Docker so much easier not worrying about if I have access to a server with Docker or spinning up a VM or Parallels session to work wit Docker.  Its now all local on my macbook to include all the terminal commands. Once Docker Desktop is installed, let's install Ansible How to deploy Ansible inside a Docker container Deploying Ansible inside a Docker container is an easy way to have a lightweight, agile env

Hosting your own fully featured Docker registry

Background  Recently, I’ve become more interested in Docker containers and registries. This is from a combination of dealing with these daily at work and publishing my own containers publicly. I thought it would be neat to publish my containers on my own private registry, on my own domain name. For example, instead of docker pull ghcr.io/nathanvaughn/webtrees it would be docker pull cr.nathanv.app/webtrees. Part of this is my constant desire to host non-critical services myself (by cri

How to export DHCP Leases to CSV file

Many exports limits to 10,000 entries but what if you have more than that then what?  Using an API call is the way to go. Here are instructions on how to export DHCP Leases from Infoblox using an API call. Pre-Req: Must have a user account with API access Must have the FQDN or IP of the GridMaster Instructions: (I'm using a Mac of course so if you are using Windows it will look different but Linux it will look the same) From the machines command prompt run

How to Decrypt SSL Traffic on LTM

For this to work you need to decrypt the traffic as it comes in.  Its too late if you did a capture and all the traffic is encrypted.  So this entry is for those of you that would like to do some work ahead of time on the F5 and then have the user do some application testing while you are running a tcpdump.  In many cases for me, I have only needed to do this on our DMZ LTM which is where the our F5 works as an SSL Bridge SETUP Put the source IPs in a txt file.  I'm calling mine /var/t

Using ssldump on F5

You can use the ssldump utility to examine, decrypt, and decode SSL-encrypted packet streams managed by the BIG-IP system. The ssldump utility can act on packet streams real-time as they traverse the system, or on a packet capture file saved in the libpcap format, such as that produced by the tcpdump utility. Although it is possible for the ssldump utility to decode and display live traffic real-time as it traverses the BIG-IP system, it is rarely the most effective method to examine the volumin

iphone video only mov

Issue I learned recently but apparently the issue has existed for awhile now. All videos you do on you iOS are .mov files which means when you attach to a post or blog it only works if you are using a Safari browser.  If you use a Chrome browser you are screwed. The standard is .mp4 format that works across the board.  It reminds me a lot of the lightning cable (apple only) vs usb-c (universal). Huge bummer to learn that only Safari browsers can view these videos that were created by A
