containers/podman-compose
Podman Compose
podman-compose is a command line tool and compose specification wrapper that translates YAML definitions into commands for the Podman container engine. It functions as a multi-container orchestrator that deploys application stacks without requiring a background daemon process.
The tool enables rootless container management, allowing the execution of containerized applications and services without administrative privileges on the host. It translates high-level compose commands into individual shell calls to coordinate the deployment of multiple containers.
The system manages container networks with DNS-based name resolution to allow services to communicate via network addresses. It also handles sequential service provisioning based on dependency definitions and maps user-space permissions to container namespaces.
Features
- Multi-Container Orchestration - Orchestrates multiple containers using a YAML specification to deploy complete application stacks.
- CLI Wrappers - Wraps high-level compose commands and translates them into specific shell calls for the Podman engine.
- Compose Orchestrators - Acts as a compose orchestrator that translates standard YAML definitions into engine-specific commands.
- Compose Specification Parsing - Reads and parses standardized YAML compose files to determine the configuration of services, networks, and volumes.
- Compose Specification Execution - Executes docker-compose YAML specifications by translating them into Podman container engine commands.
- Podman Compose Compatibility - Allows users to coordinate multiple containers using a compose specification when transitioning from Docker to Podman.
- Daemonless Container Engines - Provides a daemonless approach to container orchestration by calling the engine without a persistent background process.
- Rootless Container Runtimes - Enables the execution of containerized applications in rootless environments to minimize administrative privilege requirements.
- Rootless Container Runtimes - Enables execution of containers without administrative privileges by mapping user-space permissions to namespaces.
- Dependency-Based Orchestration - Starts containers in a specific sequence based on the dependency definitions found in the compose file.
- Container Bridge Networks - Manages shared bridge networks for containers and provides DNS-based name resolution for internal communication.
- Container Networking Configurations - Implements virtual network configurations and port mappings to enable communication between containerized services.
- Container Domain Name Resolutions - Provides DNS resolution that translates service names into reachable network addresses for containers.
- Container Orchestration - Runs compose files using Podman.
