You can define the basic authentication credentials used by your Elasticsearch cluster in a auth-file.json as follows:

{
  "username": "<USER NAME>",
  "password": "<PASSWORD>"
}

The templates can be defined in a templates.json, where you have to specified the name of the template and its body:

{
   "templates": [
       {
           "name": "template_1"
           "body": {
            "template" : "te*",
                "settings" : {
                    "number_of_shards" : 1
                },
                "aliases" : {
                    "alias1" : {},
                    "alias2" : {
                        "filter" : {
                            "term" : {"user" : "test" }
                        },
                        "routing" : "test"
                    },
                    "{index}-alias" : {}
                }
           }
       }
   ]

}

The body contains the definition of the index template, and it should be created according with the Elasticsearch's guidelines.

The templates can be created/updated by executing the command:

elstictemplate create -templates-file=templates.json -host=<ELASTICSEARCH-HOST> -port=<ELASTICSEARCH-PORT> -auth-file=auth-file.json

or using a docker container:

docker run --rm -v ${PWD}:/config -t mseoss/elastictemplate create -templates-file=/config/templates.json \
-host=<ELASTICSEARCH-HOST> -port=<ELASTICSEARCH-PORT> -auth-file=/config/auth-file.json

The existing templates can be listed with:

elastictemplate list -host=<ELASTICSEARCH-HOST> -port=<ELASTICSEARCH-PORT> -auth-file=auth-file.json

Or you can delete some existing templates as follows:

elstictemplate delete -templates=template-name1,template-name2 -host=<ELASTICSEARCH-HOST> -port=<ELASTICSEARCH-PORT> -auth-file=auth-file.json

Development

You can execute the tests and build the tool using the default make target:
