- docker-compose 로 올리기

Elastic Search와 RDB 비교

Elastic Search	Relational DB
Index	Database
Type	Table
Document	Row
Field	Column
Mapping	Schema

에러 해결

Content-Type header [application/x-www-form-urlencoded] is not supported

: https://yenoss.github.io/2017/11/10/elk/

No handler for type [string] declared on field

: string 타입을 text로 변경하니깐 해결 됨.

  그럼 string 타입은 사용할 수 없는 것인가? (좀 더 조사가 필요함)

aggregations

bucket aggregations

Kibana docker로 올리기

: docker run docker-kibana -e ELASTICSEARCH_URL=http://localhost:9200 -p 5601:5601 -d kibana
