Remove minimum constraint on OpenSearch hosts to allow empty host and refactor status API to not include OpenSearch status when host is empty #4701

bandinib-amzn · 2023-08-09T01:06:00Z

Description

Remove minimum constraint on OpenSearch hosts to allow empty host.
Bypass node compatibility check when empty opensearch host is configured.
'Opensearch is not configured' message in status API when empty opensearch host is configured.

Please note no opensearch host is only considered when explicitly configured. That means you need to add opensearch.hosts: [] in opensearch_dashboards.yml file. Default value will remain same which is http://localhost:9200 in case opensearch.hosts is commented in opensearch_dashboards.yml file.

Suggested change

summary: message ?? `OpenSearch is available`,

summary: message || `OpenSearch is available`,

|| is a safer operator to guard against '' and false.

Though, i would prefer to be stricter..

Suggested change

summary: message ?? `OpenSearch is available`,

summary: (message ?? `OpenSearch is available`) || `Unknown`,

Good idea! Refactored to be more stricter.
