curl -s -k -u elastic:'elastic1!' -XPUT "https://localhost:9200/my-index-000001?pretty"

$ curl -s -k -u elastic:'elastic1!' -XPUT "https://localhost:9200/my-index-000001?pretty"
{
  "acknowledged" : true,
  "shards_acknowledged" : true,
  "index" : "my-index-000001"
}

(or)

샤드 및 복제본 수 지정(shards[pri] : 3, replicas[rep] : 2)

curl -s -k -u elastic:'elastic1!' -XPUT "https://localhost:9200/my-index-000001?pretty" -H 'Content-Type: application/json' -d'
{
  "settings": {
    "index": {
      "number_of_shards": 3,
