Welcome!

Please [read this](https://discuss.elastic.co/t/about-the-elasticsearch-category/21) about how to format.

You need to use [the update settings API](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-update-settings.html) and not the create index if your index already exists I guess.

```auto
PUT /cedar-00001/_settings
{
  "aliases" : {
    "cedar_log" : {
      "is_write_index": true
    }
  }
}

```

But I don't know if this is what you really want to do...
