# Introduction
|
||
|
|
|
||
|
|
This directory contains an example `elasticsearch_adapter.lua` on how to
|
||
|
|
use [Lua Scripting](https://docs.ceph.com/en/latest/radosgw/lua-scripting/)
|
||
|
|
to push fields of the RGW requests
|
||
|
|
to [Elasticsearch](https://www.elastic.co/elasticsearch/).
|
||
|
|
|
||
|
|
## Elasticsearch
|
||
|
|
|
||
|
|
Install and run Elasticsearch using docker:
|
||
|
|
```bash
|
||
|
|
docker network create elastic
|
||
|
|
docker pull elasticsearch:2.4.6
|
||
|
|
docker run --net elastic -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:2.4.6
|
||
|
|
```
|
||
|
|
|
||
|
|

|
|
||
|
|
```bash
|
||
|
|
radosgw-admin script put --infile=elasticsearch_adapter.lua --context=postRequest
|
||
|
|
```
|
||
|
|
|
||
|
|
* Add the packages used in the script:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
radosgw-admin script-package add --package='elasticsearch 1.0.0-1' --allow-compilation
|
||
|
|
radosgw-admin script-package add --package='lunajson' --allow-compilation
|
||
|

|
||

```
|
||
|
|
|
||
|
|
* Restart radosgw.
|
||
|
|
|
||
|
|
* Send a request:
|
||
|
|
```bash
|
||
|
|
s3cmd --host=localhost:8000 --host-bucket="localhost:8000/%(bucket)" --access_key=0555b35654ad1656d804 --secret_key=h7GhxuBLTrlhVUyxSPUKUV8r/2EI4ngqJxD7iBdBYLhwluN30JaT3Q== mb s3://mybucket
|
||
|
|
s3cmd --host=localhost:8000 --host-bucket="localhost:8000/%(bucket)" --access_key=0555b35654ad1656d804 --secret_key=h7GhxuBLTrlhVUyxSPUKUV8r/2EI4ngqJxD7iBdBYLhwluN30JaT3Q== put -P /etc/hosts s3://mybucket
|
||
|
