Bootstrap an Index

Bootstrap an Index

Idempotently create an Elasticsearch index and verify its resulting configuration.

1. Read cluster health before writing anything, so the workflow fails fast against a cluster that cannot accept an index creation.
2. Probe for the target index with a HEAD request. A 404 here is an expected answer, not a failure, so both 200 and 404 are treated as success and the status code drives the branch.
3. Create the index with the supplied settings and mappings. Only reached when the probe returned 404, which keeps the workflow idempotent.
4. Read the index back to confirm the settings and mappings Elasticsearch actually resolved, which may include defaults the caller did not supply.

What you'll need to have ready

• index: The name of the index to bootstrap (e.g. "products").
• settings: Index settings such as number_of_shards and number_of_replicas.
• mappings: The field mappings that define the index schema.
