Podman Compose is often chosen by teams that want a Docker Compose–like workflow without running the Docker daemon. While it supports Compose files based on the Compose Specification, its scope is more limited. Therefore, understanding how Podman Compose works and where it fits is essential before using it beyond local development.
This guide explains Podman Compose fundamentals, walks through real examples, and highlights when Kubernetes becomes the better option.
Introduction to Podman Compose
Podman Compose allows developers to run Compose files using a Podman backend. However, it is important to know that Podman Compose is not maintained directly by the Podman core team. At the same time, Docker Compose is also maintained separately.
Red Hat clearly explains these differences and recommends Kubernetes YAML for advanced orchestration and production workloads (https://www.redhat.com). Because of this guidance, Podman should be viewed as a lightweight orchestration tool rather than a full replacement for Kubernetes.
Even so, the Podman team fixes Podman-related issues that affect Podman Compose. In addition, Docker Compose can also be used with Podman when required.
Prerequisites
Before working with Podman Compose, a few basics are required:
- Working knowledge of Linux
- Understanding of containers
- Familiarity with Podman
- Basic experience with Docker Compose
With these foundations, teams can start using Podman quickly for local testing.
Podman Compose with a Single Container
Podman Compose works smoothly for simple use cases. For example, a single-service Compose file can expose an application on port 8080.
services: helloservice-1: image: docker.io/mydeveloperplanet/mypodmanplanet:0.0.1-SNAPSHOT ports: - 8080:8080
Podman does not include Podman by default. Therefore, it must be installed separately using Python’s package manager.
pip3 install podman-compose
Once installed, Podman starts the container successfully. As a result, the application endpoint becomes available through the mapped port.
Podman Compose with Multiple Containers
Podman Compose also supports multi-container setups. For example, two services can run the same image while exposing different ports.
services: helloservice-1: image: docker.io/mydeveloperplanet/mypodmanplanet:0.0.1-SNAPSHOT ports: - 8080:8080 helloservice-2: image: docker.io/mydeveloperplanet/mypodmanplanet:0.0.1-SNAPSHOT ports: - 8081:8080
When started, Podman creates a default network and assigns a network alias to each service. Because of this, containers can communicate internally using service names.
As a result, basic service discovery works without additional configuration.
Networking Behavior
Podman Compose automatically creates a project-specific network. Each service receives a network alias that matches its service name.
However, internal communication must always use the container’s internal port. External port mappings only apply outside the network. This behavior is similar to Docker Compose and works well for development environments.
That said, advanced networking features are limited. Therefore, Podman is not suitable for complex microservices architectures.
Limitations in Production
Podman Compose supports only a subset of the Compose Specification. Unfortunately, there is no complete and official feature comparison available. Because of this, teams may face unexpected limitations when moving from Docker Compose.
Red Hat itself advises using Kubernetes YAML files instead of Compose files for production orchestration. Kubernetes provides stronger support for scaling, self-healing, and security.
Podman Compose vs Kubernetes YAML
Podman is best suited for local development and small test environments. Kubernetes YAML, on the other hand, is designed for production-scale container orchestration.
Because Kubernetes supports autoscaling, rolling updates, and policy-driven security, it aligns better with modern DevOps and Cloud-native practices. This becomes even more important when teams adopt Microservices, DevSecOps, and automated operations.
How ZippyOPS Supports Container Orchestration
Moving from Podman Compose to Kubernetes often requires expert guidance. ZippyOPS helps organizations design, implement, and manage container platforms that scale securely and efficiently.
ZippyOPS provides consulting, implementation, and managed services across DevOps, DevSecOps, DataOps, Cloud, Automated Ops, AIOps, MLOps, Microservices, Infrastructure, and Security. As a result, teams reduce operational risk while accelerating delivery.

Conclusion
Podman Compose is a useful tool for simple Compose files and local development workflows. However, it lacks several features required for production-grade orchestration.
Therefore, Podman should be used with clear expectations. For scalable, secure, and resilient platforms, Kubernetes YAML remains the preferred approach. With the right strategy and expert support, teams can transition smoothly and confidently.
