Database Storage

Anchore stores all metadata in a structured format in a PostgreSQL database to support API operations and searches.

Examples of data persisted in the database:

  • Image metadata (distro, version, layer counts, …)
  • Image digests to tag mapping (docker.io/nginx:latest is hash sha256:abcd at time t)
  • Image analysis content indexed for policy evaluation (files, packages, ..)
  • Feed data
    • vulnerability info
    • package info from upstream (gem/npm)
  • Accounts, users…

If the object store is not explicitly set to an external provider, then that data is also persisted in the database but can be migrated
