Docker Hub

Retrieve Container Images from Docker Hub using Cloudsmith

Docker Hub is the official registry (provided by Docker, Inc.) that allows you to find and share Docker-format container images.

It's the world’s largest repository of container images with an array of content sources including container community developers, open source projects, and independent software vendors (ISV) building and distributing their code in containers.

You can retrieve these images through Cloudsmith by enabling the upstream to Docker Hub.


Adding Docker Hub as an Upstream

Here's how you can integrate the Docker Hub Registry into your Cloudsmith account:

  1. Configure Upstream Proxying
    In your Cloudsmith repository, go to the Upstream Proxying settings.
    Click the green "Create Upstream" button and select the Docker format.
    Provide a descriptive name for the upstream, e.g., Docker Hub, and specify the URL for Docker Hub: https://index.docker.io.
    Set the desired priority.
    Select Cache and Proxy.
  2. Configure SSL Certificate Verification
    Ensure SSL certificates are verified for added security, especially for public sources.
  3. Authentication and Headers
    Docker Hub currently requires authentication. Please select a Method of "Username and Password" and add your Docker Hub account credentials.
    If you need help creating a Docker Hub account, see here.

Note: For Docker Hub, Username & Password are currently required, not optional.
