localstack-es-example.md

1. Create es domain -

aws --endpoint-url=http://localhost:4566 es create-elasticsearch-domain --domain-name dev-domain --elasticsearch-version 6.8.1

(Note: It take around 5-10 min to up the domain in localstack)

2. Check if domain is up or not(Default port is 4571) -

curl -X GET "http://localhost:9200"

3. Create new index in your domain -

curl -X PUT "localhost:9200/newindex?pretty"

4. List all indices from your domain -

curl -X GET "http://localhost:9200/_cat/indices?pretty"

5. List all elasticsearch domains -

aws --endpoint-url=http://localhost:4566 es list-domain-names

6. Delete domain from elasticsearch -

aws --endpoint-url=http://localhost:4566 es delete-elasticsearch-domain --domain-name dev-domain
