Replace ElasticSearch with OpenSearch 1.3.20 as the search backend across
charts, dev/demo deployment, and integration test setup:
- Rename charts elasticsearch-{ephemeral,index,external,curator} to
opensearch-*; ephemeral chart now runs opensearchproject/opensearch:1.3.20
with OpenSearch env names (OPENSEARCH_JAVA_OPTS, plugins.security.ssl.http.*
for TLS, DISABLE_SECURITY_PLUGIN when TLS is off).
- Replace the kibana chart with a native opensearch-dashboards chart
(opensearchproject/opensearch-dashboards:1); kibana-basic-auth secret
behavior unchanged. The Kibana index-pattern postStart import hook is
dropped (endpoint removed in OpenSearch Dashboards 1.x).
- dockerephemeral: drop the elasticsearch:6.8.23 service; OpenSearch is the
only search service, published on localhost:9200; nginx ES-proxy removed;
federation brig configs point directly at OpenSearch with basic-auth
credentials matching the mounted securityconfig.
- integration.yaml additionalElasticSearch repointed to the OpenSearch
endpoint; hack/helmfile + helm_vars release names, hosts, and cert-manager
Issuer renamed (official opensearch/opensearch release renamed to
opensearch-cluster to avoid a release-name collision).
- Brig's elasticsearch:* config keys and the Haskell client are unchanged.
Migration instructions in changelog.d/5-internal/opensearch-cutover.md.

| in your deployment values and umbrella charts must be renamed to | ||

There was a problem hiding this comment.
I don't think anyone uses this kibana chart anymore. It's a relict of the past. It's not relevant for the search index and only useable with the fluent-bit piece.
@julialongtin or are you aware of anyone using kibana/fluent-bit still
