Failing to PUT in an Index Template

Elastic Stack Elasticsearch
1

Using version 6.3.
I tried to update /_template/logstash with
"index.number_of_replicas": "0"
So I took the one I have now

{
  "logstash": {
    "order": 0,
    "version": 60001,
    "index_patterns": [
      "logstash-*"
    ],
    "settings": {
      "index": {
        "refresh_interval": "5s"
      }
    },
    "mappings": {
      "_default_": {
        "dynamic_templates": [
          {
            "message_field": {
              "path_match": "message",
              "match_mapping_type": "string",
              "mapping": {
                "type": "text",
                "norms": false
              }
            }
          },
          {
            "string_fields": {
              "match": "*",
              "match_mapping_type": "string",
              "mapping": {
                "type": "text",
                "norms": false,
                "fields": {
                  "keyword": {
                    "type": "keyword",
                    "ignore_above": 256
                  }
                }
              }
            }
          }
        ],
        "properties": {
          "@timestamp": {
            "type": "date"
          },
          "@version": {
            "type": "keyword"
          },
          "geoip": {
            "dynamic": true,
            "properties": {
              "ip": {
                "type": "ip"
              },
              "location": {
                "type": "geo_point"
              },
              "latitude": {
                "type": "half_float"
              },
              "longitude": {
                "type": "half_float"
              }
            }
          }
        }
      }
    },
    "aliases": {}
  }
}

So I changed it to

PUT _template/logstash
{
  "logstash": {
    "order": 0,
    "version": 60001,
    "index_patterns": [
      "logstash-*"
    ],
    "settings": {
      "index.number_of_replicas": "0",
      "index": {
      "refresh_interval": "5s"
      }
    },
    "mappings": {
      "_default_": {
        "dynamic_templates": [
          {
            "message_field": {
              "path_match": "message",
              "match_mapping_type": "string",
              "mapping": {
                "type": "text",
                "norms": false
              }
            }
          },
          {
            "string_fields": {
              "match": "*",
              "match_mapping_type": "string",
              "mapping": {
                "type": "text",
                "norms": false,
                "fields": {
                  "keyword": {
                    "type": "keyword",
                    "ignore_above": 256
                  }
                }
              }
            }
          }
        ],
        "properties": {
          "@timestamp": {
            "type": "date"
          },
          "@version": {
            "type": "keyword"
          },
          "geoip": {
            "dynamic": true,
            "properties": {
              "ip": {
                "type": "ip"
              },
              "location": {
                "type": "geo_point"
              },
              "latitude": {
                "type": "half_float"
              },
              "longitude": {
                "type": "half_float"
              }
            }
          }
        }
      }
    },
    "aliases": {}
  }
}

And got the error msg:

{
  "error": {
"root_cause": [
  {
    "type": "action_request_validation_exception",
    "reason": "Validation Failed: 1: index patterns are missing;"
  }
],
"type": "action_request_validation_exception",
"reason": "Validation Failed: 1: index patterns are missing;"
  },
  "status": 400
}

Deleted the old template and tried it again, still the same error. Tried putting the old one back in and still the same error.

The "logstash" : { at the start of the body should not be there. Try this instead:

PUT _template/logstash
{
  "order": 0,
  "version": 60001,
  "index_patterns": [
    "logstash-*"
  ],
  "settings": {
    "index.number_of_replicas": "0",
    "index": {
      "refresh_interval": "5s"
    }
  },
  "mappings": {
    "_default_": {
      "dynamic_templates": [
        {
          "message_field": {
            "path_match": "message",
            "match_mapping_type": "string",
            "mapping": {
              "type": "text",
              "norms": false
            }
          }
        },
        {
          "string_fields": {
            "match": "*",
            "match_mapping_type": "string",
            "mapping": {
              "type": "text",
              "norms": false,
              "fields": {
                "keyword": {
                  "type": "keyword",
                  "ignore_above": 256
                }
              }
            }
          }
        }
      ],
      "properties": {
        "@timestamp": {
          "type": "date"
        },
        "@version": {
          "type": "keyword"
        },
        "geoip": {
          "dynamic": true,
          "properties": {
            "ip": {
              "type": "ip"
            },
            "location": {
              "type": "geo_point"
            },
            "latitude": {
              "type": "half_float"
            },
            "longitude": {
              "type": "half_float"
            }
          }
        }
      }
    }
  },
  "aliases": {}
}

By the way, you are defining a mapping for _default_ in this index template. _default_ is deprecated as you can only have one document type per index as of version 6. Maybe you can change this into the actual document type that you will be using.

Thank you, it worked.
I will also check out check out the _default_.
