# od-database Go crawler 🚀

[![Build Status](https://travis-ci.org/terorie/od-database-crawler.svg?branch=master)](https://travis-ci.org/terorie/od-database-crawler)
> by terorie 2018 :P
[![](https://tokei.rs/b1/github/terorie/od-database-crawler)](https://github.com/terorie/od-database-crawler)
[![CodeFactor](https://www.codefactor.io/repository/github/terorie/od-database-crawler/badge/master)](https://www.codefactor.io/repository/github/terorie/od-database-crawler/overview/master)
* Crawler for [__OD-Database__](https://github.com/simon987/od-database)
* In production at https://od-db.the-eye.eu/
* Over 880 TB actively crawled
* Crawls HTTP open directories (standard Web Server Listings)
* Gets name, path, size and modification time of all files
* Lightweight and fast: __over 9000 requests per second__ on a standard laptop
* Lightweight and fast
https://od-db.the-eye.eu/
#### Usage
## Usage
### Deploys
1. With Config File (if `config.yml` found in working dir)
- Download [default config](https://github.com/terorie/od-database-crawler/blob/master/config.yml)
- Set `server.url` and `server.token`
- Start with `./od-database-crawler server --config <file>`
2. With Flags or env
- Override config file if it exists
- `--help` for list of flags
- Every flag is available as an environment variable:
`--server.crawl_stats` ➡️ `OD_SERVER_CRAWL_STATS`
- Start with `./od-database-crawler server <flags>`
3. With Docker
```bash
docker run \
-e OD_SERVER_URL=xxx \
-e OD_SERVER_TOKEN=xxx \
terorie/od-database-crawler
```
### Flag reference
Here are the most important config flags. For more fine control, take a look at `/config.yml`.
| Flag/Environment | Description | Example |
| ------------------------------------------------------- | ------------------------------------------------------------ | ----------------------------------- |
| `server.url`<br />`OD_SERVER_URL` | OD-DB Server URL | `https://od-db.mine.the-eye.eu/api` |
| `server.token`<br />`OD_SERVER_TOKEN` | OD-DB Server Access Token | _Ask Hexa **TM**_ |
| `server.recheck`<br />`OD_SERVER_RECHECK` | Job Fetching Interval | `3s` |
| `output.crawl_stats`<br />`OD_OUTPUT_CRAWL_STATS` | Crawl Stats Logging Interval (0 = disabled) | `500ms` |
| `output.resource_stats`<br />`OD_OUTPUT_RESORUCE_STATS` | Resource Stats Logging Interval (0 = disabled) | `8s` |
| `output.log`<br />`OD_OUTPUT_LOG` | Log File (none = disabled) | `crawler.log` |
| `crawl.tasks`<br />`OD_CRAWL_TASKS` | Max number of sites to crawl concurrently | `500` |
| `crawl.connections`<br />`OD_CRAWL_CONNECTIONS` | HTTP connections per site | `1` |
| `crawl.retries`<br />`OD_CRAWL_RETRIES` | How often to retry after a temporary failure (e.g. `HTTP 429` or timeouts) | `5` |
| `crawl.dial_timeout`<br />`OD_CRAWL_DIAL_TIMEOUT` | TCP Connect timeout | `5s` |
| `crawl.timeout`<br />`OD_CRAWL_TIMEOUT` | HTTP request timeout | `20s` |
| `crawl.user-agent`<br />`OD_CRAWL_USER_AGENT` | HTTP Crawler User-Agent | `googlebot/1.2.3` |
| `crawl.job_buffer`<br />`OD_CRAWL_JOB_BUFFER` | Number of URLs to keep in memory/cache, per job. The rest is offloaded to disk. Decrease this value if the crawler uses too much RAM. (0 = Disable Cache, -1 = Only use Cache) | `5000` |
