  Ship Fly.io app logs to simpledatalogs with fly-log-shipper and a Vector sink,
  with ids so retries count once.

# Fly.io

Fly's [log shipper](https://github.com/superfly/fly-log-shipper) is a Vector app that reads your organization's logs. Add one sink file and it posts them to `/v1/ingest`.

## Set it up

1. Create a folder with this `Dockerfile`:

```dockerfile
FROM flyio/log-shipper:latest
COPY simpledatalogs.toml /etc/vector/sinks/simpledatalogs.toml
```

2. Next to it, `simpledatalogs.toml`:

```toml
[transforms.simpledatalogs_fields]
  type = "remap"
  inputs = ["log_json"]
  source = '''
  .event_id = uuid_v4()
  .ts = .timestamp
  .level = .log.level
  .props.app = .fly.app.name
  .props.instance = .fly.app.instance
  .props.region = .fly.region
  .props.provider = .event.provider
  del(.timestamp)
  del(.log)
  del(.fly)
  del(.event)
  '''

[sinks.simpledatalogs]
  type = "http"
  inputs = ["simpledatalogs_fields"]
  uri = "https://edge.simpledatalogs.com/v1/ingest"
  method = "post"
  compression = "gzip"
  encoding.codec = "json"
  framing.method = "newline_delimited"
  request.headers.Content-Type = "application/x-ndjson"
  request.retry_attempts = 1000000
  auth.strategy = "bearer"
  auth.token = "${SDL_INGEST_KEY}"
  batch.max_bytes = 262144
  batch.timeout_secs = 5
```

3. Launch it and set its secrets:

```sh
fly launch --no-public-ips --no-deploy
fly secrets set ORG=personal ACCESS_TOKEN="$(fly tokens create readonly personal)" SDL_INGEST_KEY=sdl_sec_…
fly deploy
```

## What's stored

* `message`, `level` and `ts` from Fly's log line.
* `app`, `instance`, `region`, `provider` and `host` as props.
* The `event_id` is set before the sink, so Vector's retries never count twice.

The transform matters: Fly's raw line has an `event` object, which [`/v1/ingest`](/api/events#fields) would refuse as an event name.

Tested with Vector 0.43.1 and the shipper's own `log_json` transform.

## Keep the volume down

Every line from every app in the organization is an event. To ship one app, set `SUBJECT=logs.your-app.>` with `fly secrets set`.

## Next steps

* [Vector and Fluent Bit](/integrations/log-shippers): the same sink for any host.
