generating-docker-compose-files

Define your services, dependencies, networks, and volumes, then generate a Compose Specification format file without a version key. Include health checks, restart policies, and a custom bridge network, and produce a matching .env template for environment variables.

podman compose is a built-in Podman wrapper that delegates to docker-compose or podman-compose, offering fuller feature coverage. podman-compose is a standalone Python package translating the compose spec directly to Podman CLI, but supports only a subset of features like a single env_file.

Rootless Podman cannot bind to ports below 1024 by default. Map to high ports such as 8080:80, or set the sysctl net.ipv4.ip_unprivileged_port_start=80 to allow low ports.

On RHEL, Fedora, and CentOS, bind mounts need SELinux labels to be accessible inside containers. Append :z for shared access or :Z for private single-container access, and use :U to auto-chown volumes for rootless UID mapping.

The default podman network does not support DNS resolution between containers. Define a custom bridge network in your compose file so container name resolution works via the dnsname plugin.

Yes, the included deploy script converts compose files to Kubernetes manifests using kompose and applies them with kubectl to a specified namespace. Alternatively, podman generate kube provides a migration path from Podman deployments.
