From Docker to Podman: Migrating, Securing, and Scaling Containers for DevOps is the hands-on guide every modern DevOps engineer, cloud architect, and SRE needs to transition confidently from Docker to Podman in 2025 and beyond.
Docker changed the way we build and ship applications-but Podman takes containerization further with a daemonless, rootless, and security-first design. As enterprises demand stronger compliance, automation, and supply chain protection, Podman has become the runtime of choice across Red Hat, Kubernetes, and OpenShift ecosystems. This book shows you exactly how to migrate, secure, and scale your workloads without guesswork.
Inside, you will learn how to:
- Migrate with confidence: Convert Dockerfiles and Compose stacks to Podmanfiles, Podman Compose, and Quadlet units.
- Automate DevOps pipelines: Build, sign, and push images with Buildah and Skopeo in GitHub Actions, GitLab CI/CD, Tekton, and ArgoCD.
- Secure your workloads: Enforce rootless Podman, SELinux/AppArmor confinement, cosign signature verification, SBOMs, and vulnerability scanning.
- Scale and orchestrate: Deploy multi-container apps with Podman Pods, integrate seamlessly with Kubernetes and OpenShift, and run Podman in k3s/MicroShift clusters.
- Run in production: Use systemd Quadlet for declarative services, apply resource limits with cgroups v2, monitor with journald/Prometheus/Grafana, and optimize Podman in real-world clusters.
- Future-proof your platform: Understand industry trends, hybrid adoption strategies, and how Podman fits into edge, DevOps, and enterprise environments.
This book is purely practical-every chapter ends with a Practice Lab, and you'll complete a full end-to-end migration project that takes a cloud-native application from Docker to Podman with CI/CD, GitOps, and monitoring.
Whether you're a DevOps engineer modernizing pipelines, a platform team enforcing stronger security, or a cloud architect looking to replace Docker at scale, this book delivers the step-by-step playbook you need.
Take your container strategy into the future-migrate today, secure for tomorrow, and scale with Podman.Also from
