Why Podman?
Podman is a drop-in Docker replacement — no daemon, no root. After Docker Desktop license changes, it became the enterprise go-to.
brew install podman
podman machine init && podman machine start
podman run -d -p 8080:80 nginx
Docker Compatibility
alias docker=podman
podman build -t myapp .
podman run -d -p 3000:3000 myapp
Rootless = Secure
No privilege escalation, no root daemon to exploit. Safe for CI/CD.
Pods (K8s-Style)
podman pod create --name myapp -p 8080:80
podman run -d --pod myapp nginx
podman run -d --pod myapp redis
podman generate kube myapp > myapp.yaml
| Feature | Podman | Docker |
|---|---|---|
| Daemon | No | Yes |
| Root | No | Yes |
| License | Apache 2.0 | Mixed |
| K8s YAML | Built-in | No |
