# Elasticsearch & Kibana
|
|
|
|
|
|
|
|
|
|
Data Hub uses Elasticsearch as a search engine. Elasticsearch powers search, typeahead and browse functions for Data Hub.
|
|
|
|
|
[Official Elasticsearch Docker image](https://hub.docker.com/_/elasticsearch) found in Docker Hub is used without
|
|
|
|
|
any modification.
|
|
|
|
|
|
|
|
|
|
## Run Docker container
|
|
|
|
|
Below command will start the Elasticsearch and Kibana containers. `Data Hub` uses Elasticsearch release `5.6.8`. Newer
|
|
|
|
|
versions of Elasticsearch are not tested and you might experience compatibility issues.
|
|
|
|
|
```

|
|
|
cd docker/elasticsearch && docker-compose pull && docker-compose up
|
2019-09-08 20:25:58 -07:00
|
|
|
```
|
|
|
|
|
You can connect to Kibana on your web browser to monitor Elasticsearch via below link:
|
|
|
|
|
```

http://localhost:5601
|

## Container configuration
|
|
|
|
|
### External Port
|
|
|
|
|
If you need to configure default configurations for your container such as the exposed port, you will do that in
|
|
|
|
|
`docker-compose.yml` file. Refer to this [link](https://docs.docker.com/compose/compose-file/#ports) to understand
|
|
|
|
|
how to change your exposed port settings.
|
|
|
|
|
```
|
|
|
|
|
ports:
|
|
|
|
|
- "9200:9200"
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### Docker Network
|
|
|
|
|
All Docker containers for Data Hub are supposed to be on the same Docker network which is `datahub_network`.
|
|
|
|
|
If you change this, you will need to change this for all other Docker containers as well.
|
|
|
|
|
```
|
|
|
|
|
networks:
|
|
|
|
|
default:
|
|
|
|
|
name: datahub_network
|
|
|
|
|
```
|
