So I am trying to master DevSecOps (DevOps and Security in 30 days), here is my plan. I will be posting daily about things I learnt in a clear concise way on my channel @codemaxing also wrote a blog about them and post them on all my social media

You can join the study plan and exchange resources and what we learnt with each other
I am open for anyone to edit the sturdy plan, you can access it below

Day 01

Docker, Bare Metal, VMs & Containers 🐳💻

Bare Metal runs software directly on hardware. VMs use a hypervisor, have their own kernel, run a full OS, and are resource-heavy.

Containers are lightweight, share the host OS kernel, and run only the processes you start. They’re isolated from the host using namespaces (mnt, pid, net, uts, ipc) and their resources are managed by cgroups. Filesystem uses OverlayFS with layers and copy-on-write for efficiency.

Docker has three parts: the Client (sends commands), the Daemon (builds images, runs containers, manages networks/volumes), and the Runtime (containerd + runc, actually runs the container process).

Learned something cool at my Day 2 of DevSecOps

docker system events

Prolly rarely used Docker command.

Honestly, it’s one of the coolest commands in Docker imo.

So what does it actually do?

We know Docker follows a client–server architecture. When we use basic commands like docker logs, we’re mostly seeing what’s happening inside the container, things that are already exposed to the client.

But we rarely see what’s happening on the Docker daemon (server) side.

When you run it:
it starts streaming real-time events directly from the Docker daemon.

Now, open another terminal and run something like:
docker run alpine uptime

You’ll literally see the entire lifecycle happening in real time:

Image pulling
Container creation
Network attachment
Container start
Command execution
Container stop

Building a Realtime CCTV footage analysis AI

Currently collecting footages to train my model on

So I gave YOLO a shot for some CCTV analysis AI project, and honestly... it was fire. 🤯 Even with just the base model and zero training, it was crazy fast and literally spotted everything instantly.

They made it so easy you can get it runing in like two lines of code.

every python code i see these days is this

AWS Services - AWS Lambda
This is a series where we explore AWS Services

Lambda is like a normal server, but it only runs when it is requested, so it sleeps when it has no job.

The main concept in Lambda is the handler. You can’t write multiple endpoints like a normal server that handles many things, you only configure one handler that does one job.

Example: You want a Python noscript that sends a message to a Telegram bot.

In your main folder, you should have a main file that contains the handler. The prototype should look like this:

def lambda_handler(event, context):

Let’s say you use an API to trigger your Lambda with this JSON body:

{ "message": "Hello from Lambda" }

You access it with event["message"], then do:

bot.send(message)

Pawww 💥 message sent. Once done, the server shuts off.

Quick facts:
Max uptime: 15 minutes
Max storage (/tmp): 10 GB
