Free online client-side Docker Compose to Kubernetes converter (Kompose alternative). Instantly translate docker-compose.yml services into production-ready Kubernetes Deployment, Service, ConfigMap, and PersistentVolumeClaim YAML manifests with resource limits and health probes.
Docker Compose services mapped to Kubernetes resources
Deployments, Services, ConfigMaps, & PVCs generated
Paste your multi-container Docker Compose configuration into the input editor or click one of our pre-configured sample presets (Web + DB + Redis, Nginx + Node API, or Python + MongoDB).
Our client-side parser parses container images, exposed host/container ports, environment variables, restart policies, and named persistent volume mounts.
The converter translates Compose services into Kubernetes Deployments (apps/v1), Services (v1), ConfigMaps (v1), and PersistentVolumeClaims (v1).
Applies production best practices, including CPU and memory request/limit blocks, ImagePullPolicy rules, and NodePort/ClusterIP network configurations.
Copy or download the generated single-file multi-resource `k8s-manifests.yaml` and deploy directly to any Kubernetes cluster using `kubectl apply -f`.
Effortlessly convert multi-container local development environments (e.g. Nginx, Node.js API, PostgreSQL, Redis) into enterprise-ready Kubernetes cluster deployment manifests.
Automatically separate hardcoded container environment variables from pod definitions by generating dedicated Kubernetes ConfigMap manifests (`envFrom`).
Translate Docker named volumes (`postgres_data`, `redis_data`) into Kubernetes PersistentVolumeClaim manifests with explicit `ReadWriteOnce` access modes and storage requests.
Convert Compose `ports:` mappings into appropriate Kubernetes Service objects (NodePort for external web traffic and ClusterIP for internal microservices communication).
Docker Compose is the industry standard for orchestrating multi-container applications during local development. However, running applications in production requires the advanced scalability, self-healing, rolling deployment, and automated service discovery provided by Kubernetes (K8s).
Converting a docker-compose.yml file into Kubernetes manifests manually is time-consuming and error-prone. Each Docker Compose service must be mapped into multiple distinct Kubernetes resources: Deployments, Services, ConfigMaps, and PersistentVolumeClaims (PVC).
Our Docker Compose to Kubernetes Converter automates this transformation 100% inside your browser using static AST YAML parsing.
docker-compose.yml):k8s-manifests.yaml):Each service block defined under services: becomes an unmanaged Deployment object in Kubernetes. The converter configures spec.replicas: 1, sets matchLabels selectors, and builds the container spec containing the container image, container ports, environment references, and volume mounts.
In Docker Compose, ports: - "3000:3000" maps a container port to the host. In Kubernetes, containers inside Pods are isolated behind internal IPs. The converter generates a Kubernetes Service object that exposes the Deployment ports. Public services (Nginx, Web, API) receive type: NodePort or LoadBalancer, while internal stateful services (PostgreSQL, Redis, MongoDB) receive type: ClusterIP for internal cluster isolation.
Hardcoding environment variables inside Pod specifications violates 12-factor application design principles. The converter extracts all key-value pairs declared under environment: into a separate Kubernetes ConfigMap manifest and attaches it to the Pod container spec using envFrom.configMapRef.
Docker Compose volumes (e.g. postgres_data:/var/lib/postgresql/data) store persistent state on host paths. The converter maps volume specifications into Kubernetes PersistentVolumeClaim (PVC) manifests with accessModes: [ReadWriteOnce] and a standard 5Gi storage allocation, attaching the claim to the pod spec via spec.volumes and volumeMounts.
Unlike basic CLI conversion scripts, our converter automatically injects CPU and Memory requests (100m CPU / 128Mi RAM) and limits (500m CPU / 512Mi RAM) into every generated container specification, preventing Out-Of-Memory (OOM) host crashes and satisfying Kubernetes LimitRange policies.
Production-ready Docker Compose YAML generator for multi-container microservices stacks.
Generate optimized multi-stage Dockerfiles for Node.js, Python, Go, Rust, Java, and PHP.
Convert CLI docker run commands into clean, production-ready docker-compose.yml files instantly.
Scan Dockerfiles online for root user risks, hardcoded secrets, EOL base images, missing healthchecks, and unpinned tags.
Analyze and optimize Dockerfiles to shrink image sizes by 85%, accelerate CI/CD build speeds, and enforce non-root security standards.
