### Docker Image
I will maintain a public docker image of se-scraper. Pull the docker image with the command:
```bash
docker pull tschachn/se-scraper
```
When the image is running, you may start scrape jobs via an HTTP API:
```bash
curl -XPOST http://0.0.0.0:3000 -H 'Content-Type: application/json' \
-d '{
"browser_config": {
"random_user_agent": true
},
"scrape_config": {
"search_engine": "google",
"keywords": ["test"],
"num_pages": 1
}
}'
```
Many thanks goes to [slotix](https://github.com/NikolaiT/se-scraper/pull/21) for his tremendous help in setting up a docker image.
