Buildkite Packages provides registry support for container-based (Docker) images.

Once your container registry has been created, you can publish/upload images (generated from your application's build) to this registry via the relevant docker push commands presented on your container registry's details page.

To view and copy this docker push command:

  1. Select Packages in the global navigation to access the Registries page.
  2. Select your container registry on this page.
  3. Select Publish a Container Package and in the resulting dialog, use the copy icon at the top-right of the code box to copy this Docker push command and submit it to publish an image to your container registry.

This command provides:

  • The specific URL to publish a package to your specific container registry in Buildkite.
  • The API write token (generated by Buildkite Packages) required to publish images to your container registry.
