Is it possible to tag a node with REST API instead of defining in elasticsearch.yml? The intention is to use the tag with index.routing.allocation.include.group property. I am aware of how to define such a tag in config. But I cannot find any reference on how it can be done dynamically or not. ---

It cannot be done dynamically. You can use things like node IP and hostname though, take a look [here](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-cluster.html#allocation-filtering) at the bottom of the section. ---
