When does the tool generate a StatefulSet instead of a standard Deployment?

In Auto mode, the engine inspects each service for persistent data volumes. Services with attached database storage or persistent state are automatically scaffolded as StatefulSets with predictable network identities, whereas stateless services without persistent volumes default to standard Deployments.

Why are host bind mounts converted to emptyDir scratch volumes in Kubernetes?

In Docker Compose, relative paths like ./data bind to your local workstation filesystem. In a multi-node Kubernetes cluster, pods can schedule onto any worker node where local workstation directories do not exist. The tool maps these to emptyDir volumes or advises mounting a ConfigMap for configuration files.

Are my proprietary Compose files or database passwords uploaded to any cloud server?

Never. All YAML parsing, syntax transformation, and ZIP packaging run 100% locally in your web browser memory. Zero bytes or configuration details are transmitted over the network.

Docker Compose to Kubernetes YAML Converter

Docker Compose to Kubernetes YAML Converter

Convert docker-compose.yml files into clean Kubernetes Deployments, Services, ConfigMaps, and PVCs.

100% Client-Side Memory

Interactive Docker Compose to Kubernetes YAML Converter Workspace

Convert Docker Compose files to clean Kubernetes manifests in your browser. Generate Deployments, Services, and PVCs instantly. Free, private, no uploads.

How This Tool Works (100% Client-Side Engine)

The conversion engine parses the Docker Compose YAML using a client-side parser, validating service blocks, environment arrays, port mappings, and volume definitions. It maps Compose primitives to native Kubernetes OpenAPI schemas: services become apps/v1 Deployments or StatefulSets, exposed ports become v1 Services, environment dictionaries populate v1 ConfigMaps and Secrets, and volumes generate v1 PersistentVolumeClaims with matching volumeMounts.

Instant AST translation with zero server uploads.

Automated sensitive credential extraction into Secrets.

Pre-configured architecture presets for rapid deployment.

Step-by-Step Guide

Paste or Upload docker-compose.yml

Paste your Compose configuration directly into the editor or upload an existing docker-compose.yml file from your machine.

Customize Kubernetes Cluster Parameters

Set target namespace, preferred Service type (ClusterIP, NodePort, LoadBalancer), storage class, and toggle automatic Secret isolation.

Inspect & Download Manifests

Copy the unified all-in-one YAML, view individual manifest files in tabs, or download the entire stack as a structured ZIP archive.

Why Use This Tool: Privacy & Performance

Docker Compose is the undisputed standard for orchestrating multi-container developer environments on local workstations. However, when taking services into staging or production Kubernetes clusters (such as EKS, GKE, AKS, or bare-metal K3s), manually re-authoring every container definition into Kubernetes syntax is tedious, repetitive, and error-prone. Developers often spend hours wrestling with misaligned indentation, missing app label selectors, unconfigured pod restart policies, misconfigured volume mount paths, or plaintext environment variables committed directly to Git. ToolByte In-Browser Docker Compose to Kubernetes Converter eliminates manual migration friction. It parses your existing Compose specification into a structured abstract syntax tree, extracts container ports into native Kubernetes Services (ClusterIP, NodePort, or LoadBalancer), maps environment variables into structured ConfigMaps, isolates sensitive authentication credentials into Kubernetes Secrets, and provisions PersistentVolumeClaims for named data volumes. You can inspect the unified all-in-one manifest, browse individual split YAML files, and download the entire ready-to-deploy configuration package as a ZIP archive directly to your workstation.

Common Use Cases & Workflows

Migrating Local Stacks to Production Kubernetes

Instantly convert Docker Compose multi-service stacks into compliant Kubernetes manifests ready for kubectl apply or GitOps pipelines.

Automated Credential & Secret Separation

Automatically detect database passwords, API tokens, and JWT signing keys in compose environments and extract them into discrete Kubernetes Secrets.

Persistent Storage Provisioning (PVC)

Map Docker named volumes to standard Kubernetes PersistentVolumeClaims with custom storage class assignments and capacity sizing.

Ingress & LoadBalancer Architecture Generation

Generate production Nginx Ingress Controller manifests complete with host routing rules and Cert-Manager TLS termination blocks.

Technical Limitations & Operational Boundaries

Docker Compose "build:" directives are noted with warnings; Kubernetes clusters require pre-built container registry images (e.g. Docker Hub, GHCR, ECR).

Host bind mounts (e.g. ./config:/app/config) are converted to emptyDir volumes or ConfigMap pointers because node filesystem paths differ across Kubernetes worker nodes.

Advanced Docker networking topologies like custom bridge networks are flattened to standard Kubernetes cluster-wide pod networking (CNI).

Frequently Asked Questions

When the Secret isolation option is enabled, the converter analyzes key names. Any variables matching security keywords (such as password, secret, token, key, auth, or credential) are automatically extracted into a dedicated Kubernetes Secret manifest using stringData, while standard variables are grouped into a ConfigMap.
