I have an instance of elasticsearch running inside a Docker-container.
For testing purposes I would like to initialize the db with a set of data. Similar to postgres where one could write .sql files which where executed on container startup. What is the best way to accomplish this with elasticsearch?
I have used the Bulk API to initialize Elasticsearch with test data.
The gist of it is, you create a Newline delimited JSON file, as required by the Bulk API, like this:
{ "index" : { "_index" : "test", "_type" : "type1", "_id" : "1" } }
{ "field1" : "value1" }
(Note the newline at the end of the file. It won't work without it.)
Then upload it to the bulk endpoint, which can be done with curl, like so:
curl -X POST --data-binary '@test-data.json' \
-H 'Content-Type: application/x-ndjson' 'localhost:9200/_bulk?pretty'
