Use 7.17.29, 8.19.20 and 9.5.2, with LATEST aliases pointing at 9.x so the next major is a pointer change. Exercise TLS, auth, heap and Docker Hub on the latest image; keep 7.x, OSS 7.10.2 and non-semantic :latest tag cases only where behavior actually differs.

Restructure and rename Elasticsearch and Kibana tests accordingly, add AssertJ descriptions where a failure would otherwise be ambiguous, and rewrite the module docs so HTTPS on latest is the primary example.

Align the test REST client and custom heap JVM options with those versions.

Summary by CodeRabbit

@pioorg Would you like to give a look at this one?
It's mainly affecting tests and documentation.

📝 Walkthrough

Walkthrough

The Elasticsearch module now tests Elasticsearch 7, 8, and 9 images, TLS and heap behavior, OSS compatibility, TransportClient support, and Kibana integration. Documentation and Javadoc references were updated, and the REST client test dependency was upgraded.

Changes

Elasticsearch compatibility coverage

Layer / File(s) Summary
Version matrix and latest-image behavior
modules/elasticsearch/build.gradle, modules/elasticsearch/src/test/java/org/testcontainers/elasticsearch/ElasticsearchContainerTest.java, modules/elasticsearch/src/test/resources/test-custom-memory-jvm.options
Tests now use Elasticsearch 7, 8, and 9 image constants. Latest-image tests cover TLS, CA validation, wait strategies, Docker Hub images, and heap settings.
Version-specific and OSS compatibility tests
modules/elasticsearch/src/test/java/org/testcontainers/elasticsearch/ElasticsearchContainerTest.java
Tests cover Elasticsearch 8 HTTPS defaults, Elasticsearch 7 HTTP and security modes, custom TLS certificates, TransportClient usage, OSS behavior, and non-semantic :latest tags.
Kibana integration and documentation
modules/elasticsearch/src/test/java/org/testcontainers/elasticsearch/KibanaContainerTest.java, modules/elasticsearch/src/main/java/org/testcontainers/elasticsearch/KibanaContainer.java, docs/modules/elasticsearch.md
Kibana readiness checks now require HTTP 200 from /api/status. Kibana tests use shared image constants. Documentation references renamed tests and versioned examples.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 0147d

The updated Elasticsearch compatibility tests may fail to start the custom Elasticsearch 7 TLS container because its certificate format is incompatible with the server configuration. Resolve the certificate-format mismatch before merge.

377-379: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Keep customizedCertPath in PEM format.

Elasticsearch 7.17.29 requires PEM files for xpack.security.http.ssl.certificate_authorities. The openssl x509 -outform der command writes DER data to this path, so container startup can fail before the TLS test runs. Remove the conversion and retain the generated PEM certificate.

Thanks @dadoonet, enabled auto-merge once CI is green.

Use **7.17.29**, **8.19.20** and **9.5.2**, with LATEST aliases pointing at 9.x so
the next major is a pointer change. Exercise TLS, auth, heap and Docker
Hub on the latest image; keep 7.x, OSS 7.10.2 and non-semantic :latest
tag cases only where behavior actually differs.

Restructure and rename Elasticsearch and Kibana tests accordingly, add
AssertJ descriptions where a failure would otherwise be ambiguous, and
rewrite the module docs so HTTPS on latest is the primary example.

Align the test REST client and custom heap JVM options with those versions.

Head branch was pushed to by a user without write access

Kibana 9.5.2 redacts /api/status for callers without cluster:monitor, so the previous core.* predicate never matched and startup timed out. HTTP 200 is enough: Kibana already returns 503 until it is ready.

See doc: https://www.elastic.co/docs/api/doc/kibana/v9/operation/operation-get-status#operation-get-status-200-body-application-json-core_status_redactedresponse-object
