## What it does

The skill generates Grafana Loki setups across monolithic, simple-scalable, and microservices modes. Its primary generator is the `scripts/generate_config.py` Python script. It wires together storage backends, ingester lifecyclers, retention compactors, and Loki 3.6+ horizontal compactors. When targeting Kubernetes, it produces both a native `loki-config.yaml` and a Helm `values.yaml`.

Deployments rely on TSDB with schema v13. Changing schemas after cluster launch requires manual migration, so object storage choices and dates must be settled from day one. For OTLP ingestion, high-cardinality attributes like `k8s.pod.name` are routed into `structured_metadata` instead of index labels.

Running the generation script requires Python 3. For Loki 3.4+ Thanos storage flags or Bloom filters, the skill queries Grafana docs via the Context7 MCP server.

## Requirements
- Works with: Azure

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add akin-ozer/cc-devops-skills --skill loki-config-generator -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add akin-ozer/cc-devops-skills --skill loki-config-generator -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add akin-ozer/cc-devops-skills --skill loki-config-generator -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install akin-ozer/cc-devops-skills loki-config-generator
```

2. **Manually: put the files in place**
- File: `.github/skills/loki-config-generator/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add akin-ozer/cc-devops-skills --skill loki-config-generator -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/akin-ozer/cc-devops-skills --path devops-skills-plugin/skills/loki-config-generator
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add akin-ozer/cc-devops-skills --skill loki-config-generator -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/akin-ozer/cc-devops-skills/tree/HEAD/devops-skills-plugin/skills/loki-config-generator/SKILL.md

## When to use it
- generate Loki configs for S3, GCS, or Azure object storage
- prepare Helm values for Kubernetes cluster logging
- configure OTLP resource attributes into structured metadata
- set up horizontal compactor and retention limits

## Example prompts
- Generate a simple-scalable Loki configuration using S3 bucket my-loki-bucket with 30-day retention
- Create values.yaml for a Loki Helm deployment with OTLP ingestion enabled
- Run scripts/generate_config.py in monolithic mode with filesystem storage for local development

# Loki Configuration Generator

## Overview

Generate production-ready Grafana Loki server configurations with best practices. Supports monolithic, simple scalable, and microservices deployment modes with S3, GCS, Azure, or filesystem storage.

> **Current Stable:** Loki 3.6.2 (November 2025)
> **Important:** Promtail deprecated in 3.4 - use [Grafana Alloy](https://grafana.com/docs/alloy/latest/) instead. See `examples/grafana-alloy.alloy` for the Alloy pipeline and `examples/grafana-alloy-daemonset.yaml` for the Kubernetes deployment.

## When to Use

Invoke when: deploying Loki, creating configs from scratch, migrating to Loki, implementing multi-tenant logging, configuring storage backends, or optimizing existing deployments.

---

## Generation Methods

### Method 1: Script Generation (Recommended)

**Use `scripts/generate_config.py` for consistent, validated configurations:**

```bash
# Simple Scalable with S3 (production)
python3 scripts/generate_config.py \
  --mode simple-scalable \
  --storage s3 \
  --bucket my-loki-bucket \
  --region us-east-1 \
  --retention-days 30 \
  --otlp-enabled \
  --output loki-config.yaml

# Monolithic with filesystem (development)
python3 scripts/generate_config.py \
  --mode monolithic \
  --storage filesystem \
  --no-auth-enabled \
  --output loki-dev.yaml

# Production with Thanos storage (Loki 3.4+)
python3 scripts/generate_config.py \
  --mode simple-scalable \
  --storage s3 \
  --thanos-storage \
  --otlp-enabled \
  --time-sharding \
  --output loki-thanos.yaml
```

**Script Options:**
| Option | Description |
|--------|-------------|
| `--mode` | monolithic, simple-scalable, microservices |
| `--storage` | filesystem, s3, gcs, azure |
| `--auth-enabled` / `--no-auth-enabled` | Explicitly enable/disable auth |
| `--otlp-enabled` | Enable OTLP ingestion configuration |
| `--thanos-storage` | Use Thanos object storage client (3.4+, cloud backends) |
| `--time-sharding` | Enable out-of-order ingestion (simple-scalable) |
| `--ruler` | Enable alerting/recording rules (not monolithic) |
| `--horizontal-compactor` | main/worker mode (simple-scalable, 3.6+) |
| `--zone-awareness` | Enable multi-AZ placement safeguards |
| `--limits-dry-run` | Log limit rejections without enforcing |
