# fluentbit-generator

Writes Fluent Bit configs: INPUT, FILTER, OUTPUT, parsers and the whole log pipeline. Useful when you need log shipping set up without hand-picking plugin options.

## What it does

The skill walks the agent through seven stages. First it checks that `python3` is present and the script loads, then asks about log sources, destinations, TLS and buffering. From there it picks between script generation and a manual build from the `examples/` templates.

\`scripts/generate_config.py` covers the common cases: Kubernetes to Elasticsearch, Loki, CloudWatch or OpenTelemetry, application multiline logs, syslog, file tail to S3, HTTP to Kafka, Prometheus metrics, Lua filtering. When a request needs plugin options the script does not expose, the skill switches to manual assembly, starts from the closest template and keeps section order fixed: `[SERVICE]`, `[INPUT]`, `[FILTER]`, `[OUTPUT]`, then parsers.

Make sure `python3` is available before you start, because without it only the manual path is left. Generated files go to `fluentbit-validator` for checking; if that skill is missing, the fallback is `fluent-bit -c <generated-config> --dry-run`. Validation-only requests belong to the other skill.

## Requirements
- Works with: Kubernetes

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

2. **Manually: put the files in place**
- File: `.cursor/skills/fluentbit-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 fluentbit-generator
```

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add akin-ozer/cc-devops-skills --skill fluentbit-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/fluentbit-generator/SKILL.md

## When to use it
- build a Fluent Bit config for Kubernetes with metadata enrichment
- ship logs to Loki, Elasticsearch or CloudWatch
- parse multiline stack traces from an application
- define parsers in `parsers.conf` and wire them into filters
- fan out one log stream to several destinations

## Example prompts
- generate a Fluent Bit config for Kubernetes with Elasticsearch output
- I need a log pipeline from files to S3 in us-east-1
- add a Lua filter to my current Fluent Bit config

# Fluent Bit Config Generator

## Trigger Guidance

Use this skill when the user asks for any of the following:
- Create or update a Fluent Bit config (`fluent-bit.conf`, `parsers.conf`)
- Build a log pipeline (INPUT -> FILTER -> OUTPUT)
- Configure Kubernetes logging with metadata enrichment
- Send logs/metrics to Elasticsearch, Loki, CloudWatch, S3, Kafka, OTLP, or Prometheus remote write
- Implement parser, multiline, lua, or stream processing behavior

Do not use this skill for pure validation-only requests; use `fluentbit-validator` in that case.

## Execution Flow

Follow this sequence exactly. Do not skip stages.

### Stage 1: Set Working Context and Preflight

Use one of these deterministic command patterns.

```bash
# Option A (recommended): run from this skill directory
cd /Users/akinozer/GolandProjects/cc-devops-skills/devops-skills-plugin/skills/fluentbit-generator
python3 scripts/generate_config.py --help
```

```bash
# Option B: run from any cwd with absolute paths
python3 /Users/akinozer/GolandProjects/cc-devops-skills/devops-skills-plugin/skills/fluentbit-generator/scripts/generate_config.py --help
```

Preflight checks:
- Confirm `python3` is available.
- Confirm script help loads without errors.
- If using relative output paths, run from the intended target cwd.

Fallback:
- If `python3` or script execution is unavailable, switch to manual generation flow (Stage 4) using `examples/` templates.

### Stage 2: Clarification Questionnaire (Explicit Template)

Collect these fields before generation.

Required questions:
1. Primary use case: `kubernetes`, `application logs`, `syslog`, `http ingest`, `metrics`, or `custom`?
2. Inputs: which sources and paths/ports (for example `tail /var/log/containers/*.log`)?
3. Outputs: destination plugin(s) and endpoint(s) (host, port, uri/topic/index/bucket)?
4. Reliability/security requirements: TLS on/off, retry expectations, buffering limits?
5. Environment context: cluster name, environment name, cloud region (if applicable)?

Optional but important:
1. Expected log format: json, regex, cri, docker, multiline stack traces?
2. Throughput profile: low/medium/high and acceptable latency?
3. Constraints: offline environment, missing binaries, read-only filesystem?

If any required answer is missing, ask focused follow-up questions before generating.
