Verified steps
Deploy Thanos Receive components split by role: routing receivers (no `--receive.local-endpoint`, forward/replicate only) and ingesting receivers (no `--receive.hashrings-file`, store only)
Configure `--receive.hashrings-file` on routers to map tenants to specific ingesting receiver groups
Require the `--receive.tenant-header` (default `THANOS-TENANT`) on all writes so tenants are explicitly identified rather than falling back to `--receive.default-tenant-id`
Set `--receive.tenant-label-name` so ingested series carry a tenant label for downstream isolation in queries
Configure `--receive.replication-factor` appropriate for your durability requirements
Validate that writes without a tenant header fall into the default tenant bucket as expected, and that explicitly-tenanted writes route to their dedicated ingesters
Known gotchas
Official Thanos docs recommend the sidecar-plus-querier architecture over Receive for a global multi-tenant view; Receive's multi-tenancy model is a separate design choice with its own tradeoffs
Hashring configuration changes can be disruptive to ingesting receivers, so plan rollouts carefully
The "hard tenancy" vs "soft tenancy" terminology is common in community write-ups but may not be verbatim wording in the core Thanos docs for your version — verify against the docs matching your release
