Next Thanos release adding support to new discovery method, gRPC mTLS and two new object store providers (Swift and Azure).

Note lots of necessary breaking changes in flags that relates to bucket configuration.

Changelog also available here.

Deprecated

  • breaking: Removed all bucket specific flags as we moved to config files:
    • --gcs-bucket=<bucket>
    • --s3.bucket=<bucket>
    • --s3.endpoint=<api-url>
    • --s3.access-key=<key>
    • --s3.insecure
    • --s3.signature-version2
    • --s3.encrypt-sse
    • --gcs-backup-bucket=<bucket>
    • --s3-backup-bucket=<bucket>
  • breaking: Removed support of those environment variables for bucket:
    • S3_BUCKET
    • S3_ENDPOINT
    • S3_ACCESS_KEY
    • S3_INSECURE
    • S3_SIGNATURE_VERSION2
  • breaking: Removed provider specific bucket metrics e.g thanos_objstore_gcs_bucket_operations_total in favor of of generic bucket operation metrics.

Changed

  • breaking: Added thanos_ prefix to memberlist (gossip) metrics. Make sure to update your dashboards and rules.
  • S3 provider:
    • Set "X-Amz-Acl": "bucket-owner-full-control" metadata for s3 upload operation.

Added

  • Support for heterogeneous secure gRPC on StoreAPI.
  • Handling of scalar result in rule node evaluating rules.
  • Flag --objstore.config-file to reference to the bucket configuration file in yaml format. Detailed information can be found in document storage.
  • File service discovery for StoreAPIs:
  • In thanos rule, static configuration of query nodes via --query
  • In thanos rule, file based discovery of query nodes using --query.file-sd-config.files
  • In thanos query, file based discovery of store nodes using --store.file-sd-config.files
  • /-/healthy endpoint to Querier.
  • DNS service discovery to static and file based configurations using the dns+ and dnssrv+ prefixes for the respective lookup. Details here
  • --cluster.disable flag to disable gossip functionality completely.
  • Hidden flag to configure max compaction level.
  • Azure Storage.
  • OpenStack Swift support.
  • Thanos Ruler thanos_rule_loaded_rules metric.
  • Option for JSON logger format.

Fixed

  • Issue whereby the Proxy Store could end up in a deadlock if there were more than 9 stores being queried and all returned an error.
  • Ruler tracing causing panics.
  • GatherIndexStats panics on duplicated chunks check.
  • Clean up of old compact blocks on compact restart.
  • Sidecar too frequent Prometheus reload.
  • thanos_compactor_retries_total metric not being registered.
