Containerizing Data Jobs with Docker
A worked example of a containerized batch job: a Dockerfile that rebuilds quickly, read-only inputs and separate outputs, clean shutdown, and a release record that names an image by digest.
-
-
Image Tag and Digest
Separate a movable image tag from a content digest, retain platform identity, and update pinned artifacts through a reviewed build and test process.
-
Container Image and Container
Distinguish a packaged image from a running container, identify the writable layer, and account for the host kernel, architecture, and external inputs.
-
Bind Mount and Volume
Choose host-path sharing or Docker-managed storage, check daemon-side paths and permissions, and keep persistence separate from backups and publication.
