Elasticsearch从文件获取索引映射

Question

I am looking a way of having index mapping in a file so that it should be loaded when the elasticsearch is starting. Elstic documentation explains how to get so that using a rest call. I know that index mapping template can be use to set a mapping before creating the index. Anyone can help me how to read the index mappings from a file?

I will store the mapping details in a text file and then I want to upload the file to the elastic search.

Answer 1

if you write your own filters for any index you need to create a mapping template. logstash has many dynamic options so can map many fields by default.

but please ask your question more clear. what do you mean by reading from file ? in kibana console you can see the mappings for any index.

1. open kibana
2. go to development tools
3. type in console : GET /index/_mapping

for example if you wanna see all indices for logstash pattern , type : GET /logstash-*/_mapping

note : you can see the full mapping template like : GET /_template/logstash

note : for loading your template to elasticsearch type : curl -XPUT -H 'Content-Type:application/json' http://localhost:9200/_template/test -d@test.template.json

which "test" is your template name and "test.template.json" is your file.

hope this helps and rate if that helped. thanks
