Shell Script to Extract IP Address, MAC Address Information
This script collects the active MAC addresses, IP addresses, and associated hardware vendor information on a system. It uses the arp command to gather this network information and outputs it to an HTML file. The HTML file displays the IP address, MAC address, and includes a hyperlink to lookup the IEEE vendor information based on the first three octets of the MAC address. It also includes an option to email the results in an HTML formatted email.
Container Security
Discusses the issues surrounding container security and the principle philosophies to apply when designing a secure system. Specific advice and tips will be given on how to secure a container based system, including how to limit the privileges of containers and avoid common mistakes.
Process monitoring in UNIX shell scripting
This script monitors a hardcoded process called "ssh" and restarts it if it stops running. It will attempt to restart the process 3 times before reporting a failure. The script logs status messages to a log file called "procmon.log". It uses color codes to identify status messages. The script contains functions to monitor the process, detect failures, and close the script logging the ending status.
Redis as a message queue
Redis is being used as a message queue to asynchronously process image uploads on a website for gaming screenshots. When a user uploads images, the application server adds a message to the Redis queue containing metadata about the upload. A separate process polls the queue and processes each upload by resizing images, creating database entries, and more. This allows upload processing to happen in the background without blocking the user.

* The difference between runtime and build-time configuration, and the importance of relating the two together.
* Configuration drift, immutable mental models and mutable container file systems.
* Who configures the orchestrators?
* Emergent vs. model driven configuration.
In the process we will identify some common problems and talk about potential solutions.

I hope you find these are useful as I have. I’ll periodically add to the list, so check back occasionally.
Docker, the Future of DevOps
What is Docker and why should you care? A Docker container is like a
lightweight Virtual Machine. It gives you the benefits of a virtual machine,
isolation of your application, without the drawbacks, having to ship an entire
operating system with your application, slow startup time, and difficult
interaction with the host.
In this presentation you will learn why Docker and containerization is the
future of DevOps and how to use it efficiently. You will learn how to build,
run, and link containers, and what volumes are and what they are used for.
You will also learn about some of the many orchestration solutions that exists
for managing a cluster of containers, both locally and in the cloud.

Slides from my talk at CentOS Dojo before FOSDEM in Brussels. These slides give an overview of the features of CentOS Container Pipeline.
Introduction to Kubernetes
This document introduces Kubernetes and its key concepts. Kubernetes is an open-source container orchestration system that automates deployment, scaling, and management of containerized applications. It groups containers that make up an application into logical units called pods and manages the pods' distribution across a cluster of nodes, health checking and restarting the pods as needed. The document also provides an overview of some Docker commands and demonstrates Kubernetes using Minikube.
Introduction to Containers
Containers are changing development and deployment using technologies like Docker and Kubernetes. Containers leverage cgroups and namespaces in Linux kernels to isolate processes and share resources without full virtual machines. Docker popularized containers by making them easy to build, run and share. Kubernetes is the most popular container orchestrator, allowing containers to run together across clusters with services for load balancing, scaling and failover. Developers can now develop in containers for consistent environments, while operations teams can deploy containerized applications with automation and roll back updates if needed.
Git push to build, test and scan your containers
Various container build services offer developers to build their image with a git push and scan the container for known CVEs (as a paid service). What they don't provide is Dockerfile linting; scanners that would scan for available package updates (rpm, pip, npm, gem); a build process that rebuilds an image not only on git push but also when there's RPM update in its enabled repo or when its base image is updated.
Welcome to CentOS Container Pipeline project. It provides all these and more, out of the box, free of cost, on CentOS infra, and with focus on open source developers. All it needs is link to git repo containing the Dockerfile. And also email address to provide all that helpful information. ;)
Python in Industry
Slides from the talk given at Nirma University. Audience comprised of fifth semester Electronics & Communications (EC) Engineering students.
Swarm mode
This document discusses Docker Swarm Mode, which allows managing a cluster of Docker Engines called a swarm. Key features include integrated cluster management, declarative application deployment across nodes, automatic scaling, service discovery, and encryption between nodes. The document demonstrates initializing a swarm on two VMs, adding a worker node, deploying services in replicated and global modes, attaching services to networks, publishing service ports, updating services, and more swarm commands.
Ansible in CI
This document discusses using Ansible for continuous integration (CI) in a software development workflow. It describes polling a GitHub repository for code changes using Jenkins, which then triggers an Ansible build to deploy the code and run tests on CentOS CI infrastructure. The build process uses Vagrant and Docker and takes approximately 20 minutes. Ansible roles are used to abstract and organize playbooks for deploying the code.
Introduction to ansible
- Ansible is an automation tool that allows users to automate tasks like configuration management, application deployment, and other IT needs across multiple servers.
- It uses SSH to connect to remote servers and run commands without requiring any agents to be installed on the servers. Users only need to install Ansible on one central system.
- Ansible uses simple YAML files called playbooks to define configurations and orchestrate deployments across servers. Playbooks allow rolling updates, delegating tasks, and interacting with other systems.
Kubernetes
Kubernetes is open-source container-centric platform for automating deployment, scaling, and operations of application containers across clusters of hosts.
Atomic Developer Bundle
Atomic Developer Bundle packages some of the most widely used container orchestration tools into a single Vagrant box to provide developers with a configuration as close to production as possible!
Introducing docker
This document introduces Docker, a platform for developers and sysadmins to build and run distributed applications. It discusses what Linux containers are, how Docker uses containers to package applications and dependencies, and how containerization differs from traditional virtualization. The key benefits of Docker are that it allows applications to be easily built, shipped and run anywhere while increasing efficiency over virtual machines. A demo will show how to install Docker, pull images, create and run containers, and build custom images.
Rest apis with DRF
This document discusses creating RESTful APIs using the Django REST Framework (DRF). It begins by introducing Python, Django, and DRF. Python is an interpreted, object-oriented programming language used for backend web development, scientific computing, and more. Django is a web framework built with Python that is used by major companies. DRF is a framework that enables quickly building RESTful APIs as a Django application. The document then explains why APIs are important for separating the UI from business logic, enabling third party applications, and allowing other systems to interact with services. Finally, it outlines that a hands-on portion will cover creating a Django project, installing packages, setting up the database and URLs/views, and adding authentication to APIs
Docker hands-on
This document provides an overview of Docker terminology and hands-on Docker activities. It defines that layers in Docker are read-only file systems that images are built from, with images never changing. A Dockerfile automates building images by containing build commands. Hands-on steps demonstrate creating a container, committing it to an image, and using a Dockerfile to build an image running a Django app. The document also briefly explains using nsenter to debug containers.
