k8s-manifest-generator

What This Skill Does

The k8s-manifest-generator skill is a purpose-built tool designed to simplify the complexity of cloud-native infrastructure management. It automates the generation of production-grade Kubernetes YAML manifests, ensuring that your deployments adhere to industry best practices, security standards, and operational efficiency. By leveraging this skill, developers can move away from manual template creation, which is often error-prone and tedious. The skill handles the intricacies of defining Deployments, Services, ConfigMaps, Secrets, and PersistentVolumeClaims, ensuring proper resource allocation, health checks (liveness and readiness probes), and environment-specific variable injection. It acts as an expert companion to ensure that every manifest follows DRY (Don't Repeat Yourself) principles and maintains label consistency across all resource types.

Installation

To integrate this skill into your OpenClaw environment, use the following command in your terminal: clawhub install openclaw/skills/skills/anton-abyzov/sw-k8s-manifest-generator

Use Cases

• Production Bootstrapping: Quickly scaffold out a full suite of Kubernetes files for a new microservice.
• Security Hardening: Automatically insert resource limits and security contexts into existing but unoptimized configurations.
• Multi-Environment Management: Generate manifests for staging, development, and production environments by passing environment-specific parameters during the generation phase.
• Storage Provisioning: Generate complex PersistentVolumeClaim definitions that align with your cluster's storage classes.

Example Prompts

1. "Generate a production-ready deployment manifest for my node.js app named 'orders-service'. Include a liveness probe on /health, set memory limits to 512Mi, and reference a ConfigMap named 'orders-config'."
2. "Create a Kubernetes Service and a Secret manifest for a database connection. The service should be ClusterIP and the secret should contain placeholders for DB_USER and DB_PASS."
3. "I need a PersistentVolumeClaim for my PostgreSQL database that requires 10Gi of storage and uses the 'standard' storage class. Please include the associated StatefulSet manifest."

Tips & Limitations

• Tip: Always define your resource requests and limits; failing to do so can cause scheduling issues or nodes to run out of memory under load.
• Tip: Use envFrom to manage your environment variables rather than hardcoding values directly into your Deployment spec to improve security and readability.
• Limitation: While the skill provides production-ready templates, always conduct a kubectl diff or helm template --dry-run before applying manifests to a cluster to ensure no unexpected changes occur.
• Limitation: This skill focuses on resource generation; it does not perform automated deployment or cluster connectivity. You will still need appropriate Kubeconfig permissions to apply the generated YAML.
