Docker To K8S Manifests

docker-to-k8s-manifests

Converts Dockerfile and docker-compose.yml files into production-ready Kubernetes deployment manifests.

Usage

CLI

# From a Dockerfile
docker-to-k8s --dockerfile ./Dockerfile --output ./k8s/

# From a docker-compose.yml
docker-to-k8s --compose ./docker-compose.yml --output ./k8s/

# With custom app name
docker-to-k8s --dockerfile ./Dockerfile --name my-app --output ./k8s/

As a library

const { DockerfileParser } = require('./scripts/dockerfile-parser');
const { ComposeParser } = require('./scripts/compose-parser');
const { K8sGenerator } = require('./scripts/k8s-generator');

// Parse Dockerfile
const parser = new DockerfileParser();
const config = parser.parseFile('./Dockerfile');

// Generate K8s manifests
const generator = new K8sGenerator();
const manifests = generator.generate(config, { name: 'my-app' });

Features

• Parses Dockerfile instructions and extracts metadata
• Parses docker-compose.yml multi-service configurations
• Generates Deployment, Service, and Ingress manifests
• Estimates resource limits based on application type
• Configures liveness, readiness, and startup probes
• Validates output against Kubernetes schemas
• Applies security best practices (non-root, read-only FS, dropped capabilities)

Output

Generates the following Kubernetes resources:

• Deployment — with resource limits, probes, security context
• Service — ClusterIP with correct port mappings
• Ingress — optional, for HTTP services
• ConfigMap — for environment variables
• PersistentVolumeClaim — for volume mounts
