Add simulate template composition API _index_template/_simulate_index/{name} #55686

andreidan · 2020-04-23T17:09:35Z

This adds a new api to simulate matching the given index name against the
index templates in the system.

The syntax for the new API takes the following form:

POST _index_template/_simulate_index/{index_name}
{
  "index_patterns": ["logs-*"],
  "priority": 15,
  "template": {
	"settings": {
		"number_of_shards": 3
	}
       ...
   }
}

Where the body is optional, but we support the entire body used by the
PUT _index_template/{name} api. When the body is specified we'll simulate
matching the given index against a system that'd have the given index
template together with the index templates that exist in the system.

The response, in both cases, will return the matching template's resolved
settings, mappings and aliases, together with a special field that'll print any
overlapping templates and their corresponding index patterns.

Relates to #53101

@andreidan how would you feel about removing the "Post" prefix from the actions and class names? I think it sounds a little strange to call it PostSimulateIndexTemplate* rather than just SimulateIndexTemplate*, and I'd prefer to remove the prefix.

andreidan · 2020-04-24T18:08:55Z

@dakrone I think this is ready for review (removed the post_ prefix from the action names too)

LGTM, thanks for iterating on this Andrei! I left one more comment about adding a test that also uses composed_of (to make sure we resolve everything when simulating)

As elastic#55686 was backported the simulate index template api is no available in 7.8.

As #55686 was backported the simulate index template api is no available in 7.8.

This adds an API for simulating template composition with or without an index template. It looks like: ``` POST /_index_template/_simulate/my-template ``` To simulate a template named `my-template` that already exists, or, to simulate a template that does not already exist: ``` POST /_index_template/_simulate { "index_patterns": ["my-index"] "composed_of": ["ct1", "ct2"], } ``` This is related to elastic#55686, which adds an API to simulate composition based on an index name (hence the `_simulate_index` vs `_simulate`). This commit also adds reference documentation for both simulation APIs. Relates to elastic#53101 Resolves elastic#56390 Resolves elastic#56255
