## What it does

The skill guides your coding agent in writing Kubernetes `Deployment` manifests for production clusters. It draws on bundled reference guides covering resource allocations and RBAC configurations. The agent sets up `RollingUpdate` strategies with explicit `maxSurge` and `maxUnavailable` values instead of relying on defaults.

It enforces strict operational rules. Manifests include liveness and readiness probes, `ConfigMap` references, and security contexts. The skill strictly bans running containers as root and blocks the `latest` image tag. Because root execution is disallowed, images requiring elevated container privileges will require manual edits.

## Requirements
- Works with: Kubernetes

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill kubernetes-deployment -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/kubernetes-deployment/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/kubernetes-deployment/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill kubernetes-deployment -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/kubernetes-deployment/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill kubernetes-deployment -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/kubernetes-deployment/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aj-geddes/useful-ai-prompts kubernetes-deployment
```

2. **Manually: put the files in place**
- File: `.github/skills/kubernetes-deployment/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill kubernetes-deployment -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aj-geddes/useful-ai-prompts --path skills/kubernetes-deployment
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/kubernetes-deployment/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill kubernetes-deployment -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/aj-geddes/useful-ai-prompts/tree/HEAD/skills/kubernetes-deployment/SKILL.md

## When to use it
- Configure rolling updates with maxSurge and maxUnavailable
- Set resource requests and limits on pods
- Add liveness and readiness probes to manifests
- Configure RBAC roles and dedicated service accounts

## Example prompts
- Generate a Kubernetes Deployment manifest for api-service in namespace production with 3 replicas and a RollingUpdate strategy
- Add resource limits, requests, and health probes to this deployment yaml
- Create a dedicated ServiceAccount and RBAC configuration for the service

## Overview

Master Kubernetes deployments for managing containerized applications at scale, including multi-container services, resource allocation, health checks, and rolling deployment strategies.

## When to Use

- Container orchestration and management
- Multi-environment deployments (dev, staging, prod)
- Auto-scaling microservices
- Rolling updates and blue-green deployments
- Service discovery and load balancing
- Resource quota and limit management
- Pod networking and security policies

## Quick Start

Minimal working example:

```yaml
# kubernetes-deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: api-service
  namespace: production
  labels:
    app: api-service
    version: v1
spec:
  replicas: 3
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 0
  selector:
    matchLabels:
      app: api-service
  template:
    metadata:
      labels:
        app: api-service
        version: v1
      annotations:
// ... (see reference guides for full implementation)
```

## Reference Guides

Detailed implementations in the `references/` directory:

| Guide | Contents |
|---|---|
| [Complete Deployment with Resource Management](references/complete-deployment-with-resource-management.md) | Complete Deployment with Resource Management |
| [Deployment Script](references/deployment-script.md) | Deployment Script |
| [Service Account and RBAC](references/service-account-and-rbac.md) | Service Account and RBAC |

## Best Practices

### ✅ DO

- Use resource requests and limits
- Implement health checks (liveness, readiness)
- Use ConfigMaps for configuration
- Apply security context restrictions
- Use service accounts and RBAC
- Implement pod anti-affinity
- Use namespaces for isolation
- Enable pod security policies

### ❌ DON'T

- Use latest image tags in production
- Run containers as root
- Set unlimited resource usage
- Skip readiness probes
- Deploy without resource limits
- Mix configurations in container images
- Use default service accounts
