Description

DAOS Tier 2 offloads older DAOS objects (NLO files) to an S3-compatible object storage – e.g. AWS S3 or MinIO. By default the connection between Domino and the storage runs over HTTPS. With COS_USE_HTTP=1 it can be switched to HTTP, which only makes sense in local lab and test setups where the storage runs without a TLS certificate (typical for a fresh MinIO instance on an internal build server).

Example configuration

COS_USE_HTTP=1

Notes & pitfalls

  • Never enable in production – credentials and attachment content are transmitted in clear text.
  • Takes effect after a server restart or a reload of the DAOS configuration.
  • Complements the DAOS Tier 2 setup in the server document and the S3 credentials stored in the Credential Store.
  • A TLS-enabled reverse proxy in front of the object storage is the clean alternative for test environments without a dedicated certificate.
