📌 Essential Skills to Master Before Diving into Ansible! Ansible is a game-changer in the world of IT automation, making tasks easier and more efficient. But before you start using it, setting a solid foundation can make all the difference! Here are the key skills to build before diving into Ansible. 🚀 1️⃣ Linux Command Basics Ansible is widely used on Linux-based systems, so having a solid grasp of Linux commands—especially for managing files, users, and permissions—is crucial for success. 🐧 2️⃣ SSH Configuration and Usage Ansible uses SSH to communicate with nodes, so understanding SSH setup and key-based authentication (for secure, password-free access) is a must! 🔑 3️⃣ YAML Familiarity Playbooks in Ansible are written in YAML, so learning the syntax and format will make it easier to write and read clear, structured configurations. 📝 4️⃣ Python Fundamentals Ansible is built in Python, and many modules rely on Python libraries. You don’t need advanced skills, but basic Python knowledge will definitely help with troubleshooting. 5️⃣ Networking Basics Understanding IP addresses, subnets, and ports will be useful, especially if you’re configuring Ansible for complex networking tasks or managing multi-environment setups. 🌐 6️⃣ Inventory Management Skills Organizing target nodes efficiently is essential for smooth automation. Knowing how to use inventory files and manage hosts and groups will help you run tasks more effectively. With these foundational skills in place, you'll be well-prepared to harness the full power of Ansible and take your automation skills to the next level! 💼✨ #DevOps #Ansible #Automation #Linux #YAML #Python #Networking #ITSkills

Benefits of Golang and Why You should Consider Learning it as a DevOps Engineer Golang is a programing language that was developed by Google and became open source in2009. It was designed to combine the ease of a dynamic language like Python, while having the efficiency of a statically-typed language like C++. One of it biggest benefits is its multicore design, that allows Go to to run task’s in parallel. This is very beneficial in today’s modern infrastructure, where numerous tasks occur simultaneously: -CI/CD Pipelines -Monitoring -Logging Did you know that many of todays most popular DevOps tools were built with Golang? -Docker -Kubernetes -Vault -Terraform -Prometheus/Grafana Automation is a core aspect of DevOps culture, and Go empowers us to achieve more. We can create tools that allow us to automate faster, and with greater efficiency. As a compiled language, Go produces static binaries, making it easy to deploy and distribute. You can develop your own CLI tool and use it across different platforms be it macOS, Windows or Linux. Hopefully the reasons above inspire you enough to start learning Go! __ Enjoyed it?

Dockerfile: A Complete Guide for Beginners and Professionals Docker is a powerful tool for creating, deploying, and managing containers, and it has become the de facto standard in the software development industry. One of the core components of Docker is the Dockerfile — a text file containing instructions for building a Docker image. Understanding Dockerfile and mastering its usage is key to leveraging Docker effectively. What is a Dockerfile? A Dockerfile is a script that contains a set of commands and instructions to build a Docker image. A Docker image, in turn, is an immutable template that includes everything needed to run a container: the operating system, libraries, dependencies, and the application itself. Essential Dockerfile Instructions FROM: Specifies the base image for building a new image. For example, FROM ubuntu:20.04 sets Ubuntu 20.04 as the base image. RUN: Executes commands in the container. Typically used to install packages and perform other tasks needed to prepare the environment. CMD: Defines the command to be executed when the container starts. Unlike RUN, this command is not executed during the build process but only when the container runs. ENTRYPOINT: Specifies a command that will always run when the container starts. It can be overridden by command-line parameters when launching the container. COPY and ADD: Used to copy files and directories from the local file system to the image's file system. COPY performs simple copying, while ADD can also extract files and download them from a URL. ENV: Sets environment variables inside the container. EXPOSE: Indicates which ports will be open for external access in the container. VOLUME: Creates a mount point for persistent storage. WORKDIR: Sets the working directory for all subsequent instructions. Each of these instructions plays a vital role in defining how your image and container operate.

📊 Last week, I shared a poll about using aliases, and 8% of you said you weren't aware of them. So, I'm resharing my previous post where I explained what aliases are and how I use them to save time with Kubernetes commands. You can use them in other scenarios too. Ever used aliases in Kubernetes? They're like magic shortcuts that save you a lot of time! 😎 Here's how it works: aliases let you create custom shorthand for long kubectl commands. Think of them as your secret coding language! 🤫 To set them up in Linux, open your .bashrc or .bash_profile file and add your aliases at the bottom. Then, save, exit, and restart your terminal. Voila! You're all set with your new shortcuts! 🎉 Check out my aliases below and share yours in the comments! 👇 alias k='kubectl' alias kg='kubectl get' alias kgp='kubectl get pods' alias kgpa='kubectl get pods -A' alias kdp='kubectl delete pods' 👍🔄👤 If you find this post helpful and informative, please hit the like and share buttons to spread the knowledge! #Kubernetes #DevOps #Tips #DevOpsEngineer #DevOpsTools #Alias #HelpingHands #KubernetesCluster #DevOpsTips

This just makes sense! Here are just some refinements: 1) In programming Learn Python first, then GoLang but if you have already learned that, learn Rust, believe it or not, the projects I recently worked on Rust + DevOps, paid 2X more than my regular job/contract! 2) In server administration, while Linux dominates, don't skip the Windows part, I missed a VERY BIG opportunity just because I was not that used to Windows administration (although able to clear the basic/mid-tech round in just 2 days of study 📚), so not tough according to my learning experience,for you might vary! 3) The rest are all fine, prioritize learning AWS, Kubernetes, and the entire ecosystem around it, and you will be unstoppable!
