Docker Compose to Kubernetes Converter

What is Docker Compose to Kubernetes Conversion?

This tool automatically converts Docker Compose files into Kubernetes resource manifests. Instead of manually translating each service, volume, and network configuration, the converter parses your docker-compose.yml file and generates equivalent Kubernetes Pods, Deployments, ReplicaSets, or StatefulSets.

Docker Compose to Kubernetes Mapping

Kubernetes Resource Types

• Pod: Single instance of a container. Use for one-off tasks or testing.
• Deployment: Manages ReplicaSets and provides rolling updates. Best for stateless applications.
• ReplicaSet: Ensures a specified number of pod replicas are running. Usually managed by Deployments.
• StatefulSet: Manages stateful applications with stable network identities and persistent storage.

Example Conversion

version: '3'
services:
  nginx:
    image: nginx:latest
    ports:
      - "80:80"
    environment:
      NGINX_HOST: localhost

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
spec:
  replicas: 1
  template:
    spec:
      containers:
      - image: nginx:latest
        ports:
        - containerPort: 80
        env:
        - name: NGINX_HOST
          value: localhost

Benefits of Kubernetes

• Auto-scaling: Automatically scale based on demand
• Self-healing: Restart failed containers automatically
• Rolling Updates: Update applications with zero downtime
• Service Discovery: Built-in DNS and load balancing
• Resource Management: CPU and memory limits per container
• Multi-Cloud: Run on any cloud provider or on-premises
