```
cd src
go run main.go
```
Installing with Helm
```bash
helm repo add inventor https://code-tool.github.io/inventor/
```
Registering new target:
```bash
curl -X PUT -H "x-api-token: secret" http://127.0.0.1:9101/target \
-d '{"static_config": {"targets": ["10.0.10.2:9100",], "labels": {"__meta_datacenter": "dc-01", "__meta_prometheus_job": "node"}, "target_group": "mygroup"}}'
```
More examples: `./test/end-to-end`
Prometheus SD config example
```yaml
scrape_configs:
- job_name: http_sd
http_sd_configs:
- url: http://127.0.0.1:9101/discover
# if SD_TOKEN env variable is set
headers:
- "x-sd-token: REDACTED"
```
