Combining Index Templates with Dynamic Templates

I would like to combine Index Templates and Dynamic Templates so that the dynamic mapping I define is automatically added to all indices created.

Is this possible?

In Elasticsearch 7.x, document types are now deprecated. For this reason, the examples from old answers will raise exception. Solution below:

PUT /_template/test_template
{
  "index_patterns" : [
    "test*"
  ],
  "mappings": {
    "dynamic_templates": [
      {
        "strings": {
          "match_mapping_type": "string",
          "mapping": {
            "type": "text",
            "fields": {
              "keyword": {
                "type":  "keyword",
                "ignore_above": 1024
              }
            }
          }
        }
      }
    ]
  }
}

P.S. Also I recommend set index type "_doc" into old applications for compatibility with these templates now (fluent-bit v1.3, for example).

In the index template define the mappings as dynamic template. For example :

PUT /_template/template_1
{
  "template": "yourindex*",
  "mappings": {
    "my_type": {
      "dynamic_templates": [
        {your dynamic templates ...}
      ]
    }
  }
}

You can do something like this:

PUT /_template/my_template
{
  "template": "name-*",
  "mappings": {
    "my_type": {
      "dynamic_templates": [
        {
          "rule1": {
            "match": "field*",
            "mapping": {
              "type": "string",
              "index": "analyzed"
            }
          }
        },
        {
          "rule2": {
            "match": "another*",
            "mapping": {
              "type": "integer"
            }
          }
        }
      ],
      "properties": {
         "field": {
             "type": "string"
         }
      }
    }
  }
}
