MIGRATING FROM DOCKER TO PODMAN

Replace Docker with Podman and ship secure rootless containers without breaking your workflow.

Many teams want Docker parity with stronger security and simpler operations. This book shows how to move daily work to Podman, keep Compose productive, and run stable services with systemd and Quadlet.

Across development laptops and Linux servers, you will set up rootless containers, map users cleanly, handle networking, and adopt build and policy controls that hold up in CI and production.

• Map daily commands from docker to podman, including run exec logs cp inspect
• Set up rootless containers with subuid and subgid, storage drivers, and SELinux labels
• Use netavark with Aardvark DNS for reliable names on user defined networks
• Choose slirp4netns or pasta for rootless performance and IPv6
• Handle privileged ports safely, with sysctl tuning capability grants or rootful when required
• Run Docker Compose against the Podman socket or use podman compose
• Build with podman build and adopt Buildah for fine control and scripts
• Lock image formats and trust with registriesconf short name policy and policyjson
• Tune storage and ownership with idmaps U option named volumes and storageconf
• Harden containers with capabilities seccomp SELinux and AppArmor patterns
• Operate with Quadlet, health checks, restart policies, timers, and safe auto updates
• Bridge to Kubernetes with generate kube and validate locally with kube play
• Run on macOS and Windows using podman machine with correct sockets paths and networking
• Troubleshoot fast with logging drivers, hostname behavior, and clear failure signatures

This is a code heavy guide with working commands and configs that you can paste into terminals, unit files, and CI jobs to stand up real services quickly.
