Overview

All Kubernetes nodes have Tags, which originally is called Labels. To perform the search for the nodes by their Tags Discovery provides additional tag attributes.

tag_set: the original block of Tags stored as dict

tag_set := {"key1" : "value1", 
  		    "key2" : "value2",
            "key3" : "value3"}

2. tags: the list of tag keys allows to perform a search for nodes that contain specific keys in the attributes.

tags := [key1", "key2", "key3"]

3. tag_<node_name>: The attribute "tag_<tag_name>" with a particular value and every key is assigned it to the node attribute with a value attribute with appropriate values.

tag_key1 := "value1"
tag_key2 := "value2"
tag_key3 := "value3"
