Add extra_helm_values and data_prepper_pipeline_secret_file variables so an operator can supply a custom Data Prepper pipeline through the chart's dataPrepperManageSecret=false gate: terraform renders the file into the data-prepper-pipeline Secret and orders it before the release. Create a gp3 StorageClass (EKS ships only gp2) since the OpenSearch/Cortex storage_class variables default to gp3. Signed-off-by: Kyle Hounslow <kylhouns@amazon.com>
verbosity detailed serializes every span, log, and metric to stdout, which throttles the collector pipeline under sustained load (observed ~6x slower trace ingest at bench scale, with OpenSearch write pools idle). basic logs per-batch counts, which is enough for the debug exporter's purpose.

…from chart - create_gp3_storage_class (default true) lets operators opt out on clusters that already provide gp3 (EKS Auto Mode, manual, shared), avoiding the 'already exists' apply failure. - BYO pipeline Secret reads opensearchUsername/opensearchPassword defaults from the chart's values.yaml instead of re-hardcoding the literals, so the Secret and the cluster can't drift apart if the chart default changes. - Add var.opensearch_username, wired into the release like opensearch_password.

What
Two additive, default-no-op terraform changes that let an operator run the stack as a custom-routing backend without editing chart defaults. Builds on the
dataPrepperManageSecretgate merged in opensearch-project#308 (upstream).data_prepper_pipeline_secret_file(default""): path to apipelines.yamltemplate. When set, terraform renders it (viatemplatefile, withopensearch_user/opensearch_password/trace_flush_interval) into thedata-prepper-pipelineSecret, setsdataPrepperManageSecret=falseso the chart renders no pipeline Secret of its own, and orders the Secret before thewait=truerelease so Data Prepper mounts it at boot.extra_helm_values(default[]): additional values file paths layered onto the release last.gp3StorageClass: EKS ships onlygp2, butopensearch_storage_class/cortex_storage_classdefault togp3. Without this, gp3 PVCs hangPendingand the release times out. Created via the EBS CSI driver,WaitForFirstConsumerto match gp2.Why
The chart stays generic; a consumer supplies routing from outside. This completes the gate's usability (the gate shipped in opensearch-project#308 but nothing wired the external secret through terraform).
Status
Draft against the fork while validating end-to-end on a fresh account. Not for upstream until the full path is confirmed.
Test
terraform validatepasses;terraform fmtclean.data-prepper-pipelineSecret carries the consumer routing with no helmmanaged-bylabel (terraform-created, chart rendered nothing), Data Prepper mounted it and started, gp3 PVCs bound.
