docker-to-k8s-manifests
Automatically generate optimized Kubernetes deployment manifests from Dockerfile and docker-compose configurations with proper resource limits and health checks.
Best use case
docker-to-k8s-manifests is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Automatically generate optimized Kubernetes deployment manifests from Dockerfile and docker-compose configurations with proper resource limits and health checks.
Teams using docker-to-k8s-manifests should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# docker-to-k8s-manifests
Converts Dockerfile and docker-compose.yml files into production-ready Kubernetes deployment manifests.
## Usage
### CLI
```bash
# 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
```javascript
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 mountsRelated Skills
