Docker Hub to PostgreSQL Integration

How Datrise loads Docker Hub into PostgreSQL

Datrise syncs Docker Hub's repositories, images, tags, pull counts, image manifests, and organizations into PostgreSQL as a typed table per source entity. Flexible or custom fields land in jsonb columns, and timestamps such as created, updated, and status changes are typed as timestamptz.

Sync is incremental: Datrise uses a watermark on each entity's updated-at, applied with INSERT … ON CONFLICT DO UPDATE, so re-runs update only what changed. Optional declarative range partitioning by load date for high-volume tables. PostgreSQL folds unquoted identifiers to lowercase, so Datrise normalizes mixed-case source fields to snake_case.

Ideal for operational analytics and application backends that need fresh, queryable copies of your data.

Endpoints

Docker Hub: Container image registry and distribution.

PostgreSQL: Open-source relational database with strong SQL and extensions.

How Docker Hub entities map to PostgreSQL

Docker Hub entity	PostgreSQL object	Notes
repositories	`dockerhub_repositories`	id PK · custom fields → jsonb columns
images	`dockerhub_images`	id PK · linked to dockerhub_repositories
tags	`dockerhub_tags`	id PK · linked to dockerhub_repositories
pull counts	`dockerhub_pull_counts`	id PK · linked to dockerhub_repositories

FAQ

How does Datrise handle Docker Hub's custom fields in PostgreSQL?

Flexible values are stored as jsonb columns, so new fields don't require a migration; strongly-typed fields — dates, numbers, and references — are promoted to native PostgreSQL types.

How does the Docker Hub to PostgreSQL sync stay up to date?

It runs incrementally — Datrise uses a watermark on each entity's updated-at, applied with INSERT … ON CONFLICT DO UPDATE.
