Anchore-engine is backed by a postgres database, and will bootstrap the first time it runs by populating it's database with a full set of vulnerability data. By default, against the stable postgres container image (or any empty postgres database), this initial process can take some time (10+ minutes with a reasonably fast network). The purpose of this image is to facilitate a faster bootstrap of anchore-engine, by having a postgres container configured to pre-load a snapshot of vulnerability data.

To make use of this container image, the image anchore/engine-db-preload:latest can be substituted for postgres:9 in any docker-compose.yaml configurations or any other deployment configuration that references the postgres:9 container image in support of anchore-engine.
