Kompose
Kompose is a suite of conversion utilities designed to translate container composition files into cloud-native cluster resource definitions. It serves as a migration tool that transforms local development specifications into production-ready manifests for Kubernetes and OpenShift.
The tool functions as a translation engine that maps container specifications, network settings, and workload definitions into cluster resources. It supports target-specific manifest generation through dedicated providers, allowing for the creation of resources tailored to different environment distributions.
The project covers a broad range of conversion capabilities, including the mapping of network ports to services, the translation of storage volumes into persistent volume claims, and the conversion of security contexts and environment secrets. It also integrates workflows for building container images and pushing them to registries during the migration process.
Users can apply generated manifests directly to a cluster via integrated API communication or output them as files for manual deployment.
Features

- Compose Converters - Converts local container configuration files into Kubernetes manifests to migrate applications from a single machine to a cluster.
- Workload Resource Definitions - Translates replica counts, placement affinities, and resource limits into Kubernetes workload resource definitions.
- ConfigMap and Secret Generators - Maps environment variables and secret files to Kubernetes-native ConfigMap and Secret resources.
- Schema-Driven Specifications - Maps Compose YAML fields to Kubernetes object specifications using predefined structural conversion rules.
- Container Port Mappings - Maps exposed ports and network rules to cluster service specifications to ensure connectivity.
- Storage Volume Orchestration - Transforms local volume declarations and temporary file systems into persistent volume claims and directory mounts.
- Kubernetes Resource Generators - Creates Kubernetes-native resource definitions for workloads, services, and storage based on existing container composition files.
- Manifest Translators - Translates local container specifications and network settings into cloud-native workload definitions.
- Orchestration Migrations - Translates development environment specifications into production cluster resources to automate the deployment of multi-container applications.

How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
