Repositories with pull counts
Repository metadata including aggregate pull count, stars, and storage size.
Docker Hub
Polytomic connects Docker Hub to your data warehouse, databases, and SaaS tools for registry ETL. Replicate public repositories and their tags into your data warehouse and other systems so image adoption and release history can be tracked alongside your product data, without writing code.
Tags with image detail
Tag metadata plus embedded image variants by architecture and OS.
Incremental repositories
Repository reads stop once they reach the previous checkpoint.
Example workflows
Replicate Docker Hub repositories into your data warehouse
What you can sync
Docker Hub is supported as a source. Read public repositories and their tags, then land them in your data warehouse, databases, or SaaS tools.
From Docker Hub
Repositories with description, stars, and visibility
Aggregate pull count and storage size
Repository tags with push and pull timestamps
Image variants nested on tags, by architecture and OS
To your destinations
Data warehouses including Snowflake, BigQuery, and Databricks
Databases including PostgreSQL and MySQL
Cloud storage including Amazon S3 and Azure Blob Storage
SaaS tools including Salesforce, HubSpot, and spreadsheets
How it works
Point Polytomic at a Docker Hub namespace and it reads the repositories there, along with their tags and image variants, into your data warehouse, databases, or SaaS tools. Registry activity becomes a table you can trend rather than a page you check.
Because Docker Hub reports only a current aggregate pull count rather than a history, syncing on a schedule is what turns that single number into a time series you can actually chart.
- Configure a Docker Hub namespace to read
- Read repositories with pull counts, stars, and storage size
- Read tags with their embedded image variants
- Sync repositories incrementally from the previous checkpoint
- Snapshot pull counts on a schedule to build a trend
- Monitor sync health, record volume, and failures from one interface
How to set up
The connection takes a Docker Hub namespace, meaning the organization or user whose repositories you want to sync. Requests are unauthenticated, so no credentials are required.
How to get connected
- 1Identify the Docker Hub namespace you want to read
- 2In Polytomic, navigate to Connections, then Add Connection, then Docker Hub
- 3Enter the namespace
- 4Test the connection
- 5Select repositories, repository tags, or both
- 6Click Save
