DevOps · DevSecOps · Cloud Native Engineering

Built from the field.
Not from the docs.

DeployCraft.io is written by a practitioner with nearly a decade across the full SDLC — software engineering, quality operations, and cybersecurity. Every guide covers Kubernetes, CI/CD, GitOps, Infrastructure as Code, and DevSecOps from first principles to production deployment.

Who this is for

⚙️

Platform & DevOps engineers

Running Kubernetes in production and looking for depth beyond the official docs — security hardening, autoscaling, multi-cluster ops, and GitOps delivery.

🔐

DevSecOps practitioners

Responsible for securing CI/CD pipelines, hardening workloads, and integrating security tooling across the software delivery lifecycle.

📈

Engineers levelling up

Software engineers transitioning into platform, infrastructure, or security roles — building the practical knowledge that certifications alone do not cover.

🎯

Security professionals

Penetration testers, red teamers, and security engineers who need to understand the engineering side — pipeline attack surfaces, supply chain vulnerabilities, and how Kubernetes clusters are built and hardened.

What we cover

🛡️

Kubernetes Security & Hardening

Pod security, RBAC, admission webhooks, secrets management, and workload isolation — from basics to production enforcement.

🔁

GitOps with ArgoCD & Helm

Declarative delivery with Flux, ArgoCD, Helm, and Kustomize. Multi-environment management, canary releases, and automated rollbacks.

Explore →
📦

CI/CD with GitHub Actions

Pipeline design, container image builds, registry integration, and automated GitOps reconciliation triggered from CI.

Explore →
📐

Infrastructure as Code

Terraform and Ansible patterns for provisioning, configuring, and managing cloud-native infrastructure at scale.

Explore →
🐧

Linux for Secure Systems

Linux fundamentals, hardening techniques, and system administration skills that underpin every container and cluster.

Explore →
🔍

Red/Blue Team Toolchains

Pipeline security, supply chain integrity, secret scanning, SAST/DAST integration, and DevSecOps tooling for attack and defence.

Why DeployCraft.io exists

Most DevSecOps content is either too shallow to apply in production or too theoretical to ship.

Every guide is written from real-world experience: the same problems encountered hardening Kubernetes clusters, securing CI/CD pipelines, managing infrastructure at scale, and assessing systems from both the engineering and security perspective. Content spans the full spectrum, cluster hardening, RBAC, admission webhooks, and supply chain integrity through to red and blue team toolchains, SAST/DAST integration, secret management, and pipeline attack surfaces.

Content is structured as linked pairs — Part 1 builds the foundation, Part 2 takes it to production, so you always leave with something deployable, not just something readable. Whether you are building, securing, or breaking systems, the goal is the same: depth you can actually use.
