207 Shell Scripts for DevOps & SRE Automation

Making DevOps Life Easier : 207 Shell Scripts for Everyday Automation! Hey everyone. Over the past few months, I’ve been building a collection of shell scripts to simplify repetitive DevOps tasks — from server setup and log monitoring to CI/CD automation and cloud operations. What started as a small set of helper scripts turned into a repository of 207 automation scripts — all written to make engineers’ lives easier, save time, and reduce manual errors. These scripts cover: -System monitoring & health checks -Docker & Kubernetes automation -AWS CLI tasks -CI/CD & deployment workflows -Backup, cleanup & performance tuning -And a lot more! If you’re a DevOps Engineer, SRE, or Cloud Enthusiast, this might be super useful for your daily work or learning. I’m happy to share this with the community — hoping it helps someone automate just a little bit more . #DevOps #Automation #ShellScripting #Cloud #Kubernetes #AWS #CICD #Productivity #SRE #Linux #OpenSource

🚀 Who is a DevOps Engineer? A DevOps Engineer bridges development and operations to build, automate, and deliver software faster and more reliably. From code → CI/CD → containers → cloud → users, the focus is on speed, automation, scalability, and stability. ⚙️ 💡 Key areas: ✔️ Automate repetitive tasks ✔️ Fast & reliable deployments ✔️ Scalable infrastructure ✔️ Continuous monitoring & feedback ✔️ Security & system reliability DevOps is not just a role — it’s a mindset of continuous improvement. 🔁 #DevOps #DevOpsEngineer #CloudComputing #AWS #Docker #Kubernetes #CICD #Automation #Linux #SoftwareEngineering #Monitoring #Scaling #Tech #I

Most teams aim to ship faster without compromising production. For the past few years, this has been my primary focus as a DevOps engineer. I have worked on end-to-end cloud infrastructure and CI/CD on AWS and GCP for over 40 Java and Python microservices and AI workloads, utilizing Kubernetes (EKS/GKE), Terraform, and modern observability stacks. Throughout this journey, I have helped reduce cloud and GPU spending by approximately 25% and cut release and remediation times by 30–60% through automation and improved pipelines. Recently, I have taken ownership of AWS infrastructure across development, staging, and production environments, building CI/CD with Jenkins, GitHub Actions, and GitLab webhooks. I have also implemented monitoring solutions with Prometheus/Grafana, ELK, and CloudWatch to ensure high availability and cost efficiency. Additionally, I designed an AI-driven Docker image CVE remediation pipeline integrated with CrowdStrike and LLMs, which has reduced manual patching efforts by 50–60% and provided leadership with real-time visibility into our security posture. I enjoy working with teams that treat DevOps, SRE, and platform engineering as core disciplines for building secure, scalable systems and would love to exchange ideas with others on the same path. #DevOps #SRE #PlatformEngineering #AWS #Kubernetes #Terraform #CICD #CloudEngineering

A DevOps engineer I spoke to once said something that stuck with me. "I know Kubernetes well. But the moment our org moved to OpenShift, I felt like a junior again." That feeling is more common than people admit. OpenShift and Kubernetes share the same foundation — but OpenShift adds an entire layer of enterprise complexity on top. Security contexts. Operators. Build pipelines. Service mesh. Cluster upgrades at scale. Things that simply don't exist in vanilla Kubernetes, and that no amount of K8s experience fully prepares you for. Most people learn by trial and error. Production breaks. Incidents happen. You piece it together over months. Learn OpenShift (2nd Edition) was written by architects who've worked on some of the world's largest OpenShift deployments— in banking, healthcare, telecoms, and transportation. It covers OpenShift 4 internals, architecture, cluster installation and upgrades, security, application builds, observability, and service mesh — the stuff that's rarely documented well anywhere else. Built for DevOps engineers, architects, SREs, and sysadmins who already understand Linux and Kubernetes, and want to master OpenShift 4 in enterprise environments.

Tools I use every single day as a Senior DevOps Engineer ⚙️ ☁️ Azure for cloud infrastructure 🔄 Azure DevOps for CI/CD pipelines 💻 GitHub for source control and collaboration 🏗️ Terraform for infrastructure as code 🔍 Elastic for centralized logging and search 📊 New Relic for application monitoring and observability 🐳 Docker for containerized environments ☸️ Kubernetes when orchestration is actually needed 🐧 Linux, obviously Previously worked heavily with AWS, Jenkins, Grafana, and Prometheus across different projects. But here's the thing. Knowing the tools isn't enough. Knowing WHEN to use which tool and WHEN not to, that's where the real skill is. I've seen teams set up complex monitoring dashboards but miss the one metric that actually matters. I've seen engineers monitor everything in New Relic except the thing that breaks at 2 AM. Tools are easy to learn. Judgment takes time. Which DevOps tool changed your workflow the most? 👇 #DevOps #Azure #Terraform #Kubernetes #Elastic #PlatformEngineering

Ever wondered what a DevOps Engineer actually does all day? 🤔 It’s not just about writing scripts or managing servers. One moment you're fixing a broken deployment at 2 AM… Next moment you're designing a pipeline that saves hundreds of hours for your team. DevOps is where: ⚙️ Development meets Operations 🚀 Speed meets Stability 🧠 Automation meets Creativity But here’s the real question: 👉 Are we just becoming “tool operators” (Docker, Kubernetes, CI/CD)? 👉 Or are we actually solving real business problems? Because the best DevOps engineers I’ve seen don’t just use tools — they: ✔️ Understand systems deeply ✔️ Think in automation-first mindset ✔️ Design scalable and resilient architectures And honestly… that’s what separates an average engineer from a high-impact one. 💬 Let’s discuss: What do YOU think is the most important skill for a DevOps Engineer in 2026? Mastering tools? Strong Linux & networking basics? Cloud expertise? Or problem-solving mindset? Drop your thoughts 👇 #DevOps #CloudComputing #Automation #Kubernetes #AWS #CareerGrowth #TechCareers
