DevOps Tooling: The Complete Guide to Modern Infrastructure Automation
Daily updated tutorials, guides, and projects for DevOps engineers in 2025.
DevOps tooling is the backbone of modern software delivery — the collection of platforms, CLIs, and automation systems that let teams provision infrastructure, automate builds and deployments, and observe running systems. On this site you’ll find hands-on, practical tutorials for core tools like Terraform, Kubernetes, Ansible, GitHub Actions, AWS, Docker, Prometheus, and Grafana. Each guide includes commands, code snippets, and real projects you can run locally. Read daily updates to build a portfolio and move from beginner to job-ready.
Core Pillars — DevOps Tooling
These are the foundation guides that explain not just how a tool works, but how to use it in a real workflow with examples, common pitfalls, and career-focused projects.
Grafana
Dashboards, panels, alerts and observability best practices.
Argo CD
GitOps continuous delivery for Kubernetes: app deployments, sync policies and promotion workflows.
Jenkins
Classic CI server: pipelines, agents, scripted pipelines, integrations and best practices for automation.
Terraform
Infrastructure as Code: provisioning, modules, state management and cloud providers.
Kubernetes
Cluster architecture, deployments, services, ingress, and Helm charts.
Ansible
Playbooks, roles, inventory patterns and secrets management.
GitHub Actions
Workflows, secrets, matrix builds and CI/CD pipelines for GitHub repos.
AWS
CLI automation, EC2, S3, IAM best practices, and cloud-native integrations.
Docker
Container builds, multi-stage Dockerfiles, compose and registry workflows.
Networking
IP addressing, subnets, routing, DNS, load-balancing, and troubleshooting for cloud and on-prem infra.
Linux
Essential sysadmin skills: shell, processes, package management, services, permissions and automation.
Prometheus
Metrics collection, PromQL basics, and Kubernetes integration.
