Manage index templates

Elastic Stack Serverless

Create, edit, clone, and delete your index templates in the Index Templates view. Changes made to an index template do not affect existing indices.

In Elastic Cloud Serverless, the default logs template uses the logsDB index mode to create a logs data stream.

If you don’t have any templates, you can create one using the Create template wizard.

Try it: Create an index template

In this tutorial, you’ll create an index template and use it to configure two new indices.

Step 1. Add a name and index pattern

In the Index Templates view, open the Create template wizard.
In the Name field, enter my-index-template.
Set Index pattern to my-index-* so the template matches any index with that index pattern.
Leave Data Stream, Priority, Version, and _meta field blank or as-is.

Step 2. Add settings, mappings, and aliases

Add component templates to your index template.

Component templates are pre-configured sets of mappings, index settings, and aliases you can reuse across multiple index templates. Badges indicate whether a component template contains mappings (M), index settings (S), aliases (A), or a combination of the three.

Component templates are optional. For this tutorial, do not add any component templates.
Define index settings. These are optional. For this tutorial, leave this section blank.
Define a mapping that contains an object field named geo with a child geo_point field named coordinates:

Alternatively, you can click the Load JSON link and define the mapping as JSON:
```
{
  "properties": {
    "geo": {
      "properties": {
        "coordinates": {
          "type": "geo_point"
        }
      }
    }
  }
}
```
You can create additional mapping configurations in the Dynamic templates and Advanced options tabs. For this tutorial, do not create any additional mappings.
Define an alias named my-index:
```
{
  "my-index": {}
}
```
On the review page, check the summary. If everything looks right, click Create template.

Step 3. Create new indices

You’re now ready to create new indices using your index template.

Index the following documents to create two indices: my-index-000001 and my-index-000002.

		 POST /my-index-000001/_doc {
  "@timestamp": "2019-05-18T15:57:27.541Z",
  "ip": "225.44.217.191",
  "extension": "jpg",
  "response": "200",
  "geo": {
    "coordinates": {
      "lat": 38.53146222,
      "lon": -121.7864906
    }
  },
  "url": "https://media-for-the-masses.theacademyofperformingartsandscience.org/uploads/charles-fullerton.jpg"
}

POST /my-index-000002/_doc
{
  "@timestamp": "2019-05-20T03:44:20.844Z",
  "ip": "198.247.165.49",
  "extension": "php",
  "response": "200",
  "geo": {
    "coordinates": {
      "lat": 37.13189556,
      "lon": -76.4929875
    }
  },
  "memory": 241720,
  "url": "https://theacademyofperformingartsandscience.org/people/type:astronauts/name:laurel-b-clark/profile"
}

	

Use the get index API to view the configurations for the new indices. The indices were configured using the index template you created earlier.
```
 GET /my-index-000001,my-index-000002 
```
