How do I convert docker-compose.yml to Kubernetes manifests?

Paste your docker-compose.yml file into the input editor or choose one of the pre-loaded stacks. The converter automatically parses all services, ports, environment variables, healthchecks, volume mounts, and resource constraints, converting them into valid, modern Kubernetes manifests (apps/v1 Deployment, v1 Service, v1 PersistentVolumeClaim, v1 ConfigMap/Secret, and networking.k8s.io/v1 Ingress).

Why use this tool instead of the official Kompose CLI?

The official Kompose tool is a CLI-only binary that requires local installation, Go toolchains, or container runtimes, and by default splits your stack into dozens of disconnected YAML files across your file system. This web studio runs 100% in your browser without terminal commands, bundles resources into a unified all-in-one manifest, and provides live customization for namespaces, service exposure types, and storage classes.

Why do legacy converters like 8gwifi.org and javainuse fail on modern Kubernetes clusters?

Outdated converters generate deprecated Kubernetes APIs like 'extensions/v1beta1' for Ingress and Deployments, which were completely removed in Kubernetes 1.22+. Deploying those manifests to modern Kubernetes, Minikube, or K3s clusters results in API rejection errors. Our studio exclusively generates active, production-grade Kubernetes API versions ('apps/v1', 'v1', and 'networking.k8s.io/v1').

How are Docker named volumes and host mounts converted?

Named volumes (such as 'pgdata:/var/lib/postgresql/data') are automatically converted into Kubernetes PersistentVolumeClaims (PVCs) requesting your specified storage capacity (e.g. 5Gi) and StorageClass ('standard'). Host bind mounts (such as './html:/var/www/html') are converted into Kubernetes 'hostPath' volumes for local testing environments like Minikube, Docker Desktop K8s, or Kind.

How do Docker healthchecks map to Kubernetes probes?

Docker healthcheck test commands (e.g., 'pg_isready -U postgres' or 'curl -f http://localhost:8080/health') are mapped directly into Kubernetes 'livenessProbe' exec commands, translating interval, timeout, and retry counts into 'periodSeconds', 'timeoutSeconds', and 'failureThreshold'.

Can I extract environment variables into ConfigMaps or Secrets?

Yes! Use the Environment Mapping toggle under the generation settings. You can choose 'Inline env' (embedded directly inside the container spec), 'Separate ConfigMap' (generated as a reusable v1 ConfigMap with envFrom), or 'Separate Secret' (for database passwords and API tokens).

Is this conversion private and safe for proprietary code?

Absolutely. All YAML parsing and Kubernetes manifest synthesis happen 100% inside your browser using client-side JavaScript. No Docker Compose files, container images, environment variables, or private tokens are ever transmitted across the network.

Why Convert Docker Compose to Kubernetes?

While Docker Compose is the gold standard for local container development, deploying multi-service microservices to production cloud infrastructure requires Kubernetes orchestration for auto-scaling, rolling zero-downtime updates, self-healing, and declarative service networking.

However, manually authoring dozens of verbose Kubernetes manifests—mapping container ports to v1 Service resources, configuring PersistentVolumeClaims, and translating deploy.resources to CPU/memory requests—is error-prone and time-consuming.

Kompose CLI vs. Legacy Converters vs. Our Web Studio

Here is how this modern, in-browser studio solves the limitations of official CLI binaries and outdated legacy web tools:

Feature	Legacy Converters (8gwifi, javainuse)	Kompose CLI	Kompose Web Studio (This Tool)
Kubernetes API Versions	Deprecated extensions/v1beta1 (Fails on K8s 1.22+)	apps/v1	100% Valid apps/v1, v1 & networking.k8s.io/v1
Installation Required	None (Ad-cluttered websites)	Terminal CLI binary required	Zero install, 100% In-Browser
Manifest Output Format	Broken text dumps	Splits into dozens of separate files	Single-click All-in-One YAML or Resource Sub-tabs
Storage Handling	Ignores volumes	Generic hostPath or PVC	Automated Named Volume ➔ PVC mapping with StorageClass
Healthchecks to Probes	Unsupported	Basic	Automatic CMD-SHELL ➔ LivenessProbe with interval/retries
Data Privacy	Transmits code to external servers	Local machine	100% Offline, Zero Server Uploads

How Compose Concepts Map to Kubernetes

Services (services.web): Converted into a Kubernetes Deployment with matching labels (app: web). If ports are mapped, a companion Kubernetes Service is generated.
Ports (8080:80): Mapped to containerPort: 80 inside the Pod template, and exposed via port: 8080, targetPort: 80 in the Service resource.
Environment Variables: Preserved as inline env key-value pairs, or extracted cleanly into separate ConfigMap or Secret manifests using the settings panel.
Volume Mounts (pgdata:/var/lib/postgresql/data): Named volumes generate persistent PersistentVolumeClaim resources with ReadWriteOnce access mode.
Resource Limits (deploy.resources.limits): Converted into standard Kubernetes resources.limits and resources.requests using normalized millicores (500m) and binary mebibytes (512Mi).
