  •  Disposable Infrastructure
  •  Its really fun 😷  , It is always good to know how things work..
Requisite:
  • Lxd installed on your workstation (local laptop or wherever you are going to accomplish this)
  • Love for Linux💝
Theorem:👇
  • Create a LXD Profile 
  • Launch Container
  • Get high on Contianers  🎶
Lets get our hands dirty...




In case you are interested in theory and concepts:
  • Profiles store any configuration (key/value or devices) that an instance(container instance) can  have
  •  /etc/subuid && /etc/subgid  (idmaps for user namespace) : - mapping uids and gids on host to a set of uids and gids in a container

Prerequisites Before we dive into packet analysis, make sure you have the following set up: Two Endpoints (VMs or Containers) Wireshark tcpdump It’s also important to have a basic understanding of: TCP SSH Linux Introduction In this blog post, I'll guide you through the step-by-step process of analyzing SSH connection packets using Wireshark. Whether you're troubleshooting SSH issues or simply curious about how SSH works at the protocol level, this tutorial is for you. We'll cover both successful and failed SSH connections, examining the packet flow and explaining what’s happening in the background. I've already set up a working environment for this use case. Let’s dive right into packet capture and analysis, and uncover what happens during an SSH connection. Fig. 1: A list of servers with roles and IP addresses for quick network reference. Breaking Down Packet Capture and Analysis: A Step-by-Step Guide In this post, we'll break down the process of packet capture...

Continuous Integration  (CI) is a development practice where developers commit  code into a shared repository frequently, preferably several times a day. Each commit  then gets verified by an integrated & automated build and similarly with integrated & automated tests. While automated tests aren't strictly part of CI but typically implied. The posted video includes two demos with relative examples and CI concepts. Demo 1:    Python Flask API, Test Cases, Azure DevOps Intro, Docker Multi Stage Builds & CI with GitHub Demo 2:    Python Django MVT Application, Jenkins pipeline , Docker Hub , Terraform, GitHub
