Docker images for Coffea Columnar Object Framework For Effective Analysis

Latest DockerHub Images: https://hub.docker.com/orgs/coffeateam/repositories

Coffea image tags

• dev- tags represent the status of dev branch
• head- tags represent the status of main branch
• 202x.x.x- and 0.7.x.-, as well latest represent relevant tags in this repository

Image flavours

Images are named <flavour>-<distro>. The flavour says what is in the image:

Flavour	coffea	dask-awkward / dask-histogram	dask / distributed
coffea-0.7	0.7.x	n/a	as resolved
coffea-dak	CalVer	yes (dak is the usual import alias)	as pinned in the env file
coffea	CalVer	no	no upper pin

Use coffea-dak-* unless you have a reason not to: it is the supported image and the one that can run the dask-awkward / hist.dask code paths.

coffea-* exists to test whether dropping dask-awkward allows a newer dask / distributed. It cannot run hist.dask.

Coffea 2024+ (CalVer) images

• Dockerfiles and conda environment files are available in coffea-dask directory
• All distro variants build from a single coffea-dask/Dockerfile, selected by the BASE_IMAGE, ENV_YAML and NODAK build args

Image	Environment file	Description	Last Tag Version
coffea-dak-almalinux8	environment.yaml	Alma8, CalVer coffea with dask-awkward, latest XRootD and CA certificates
coffea-dak-almalinux9	environment.yaml	Alma9, CalVer coffea with dask-awkward, latest XRootD and CA certificates
coffea-dak-almalinux9-eaf	environment-eaf.yaml	Alma9, EAF variant
coffea-almalinux9	environment.yaml (filtered)	Alma9, same env as coffea-dak-almalinux9 with dask-awkward removed and the dask pin lifted
coffea-almalinux9-noml	environment-noml.yaml	Alma9 without the ML stack. Has no dask-awkward and no dask pin

environment-eaf.yaml currently lists dask-awkward but not dask-histogram, so hist.dask is not importable in the EAF image and the hist.dask test is skipped there.

Coffea 0.7.x images

• Dockerfiles and conda environment files are available in coffea-base directory

Image	Description	Last Tag Version
coffea-0.7-almalinux8	Alma8 Dask Coffea 0.7.x image with latest XRootD and CA certificates
coffea-0.7-almalinux9	Alma9 Dask Coffea 0.7.x image with latest XRootD and CA certificates

Renamed images

The previous names said which directory an image was built from, not what was in it: dask meant CalVer and base meant 0.7.x. They have been renamed:

Old name	New name	Contents changed?
coffea-base-almalinux8	coffea-0.7-almalinux8	no
coffea-base-almalinux9	coffea-0.7-almalinux9	no
coffea-dask-almalinux8	coffea-dak-almalinux8	no
coffea-dask-almalinux9	coffea-dak-almalinux9	no
coffea-dask-almalinux9-eaf	coffea-dak-almalinux9-eaf	no
coffea-dask-almalinux9-noml	coffea-almalinux9-noml	no (it never had dask-awkward)

The old names are still published as aliases of the new ones — same digest, same contents — so existing pulls keep working. They will stop being updated; please move to the new names. No old name has been reused for a different image, so nothing you already pull can silently change underneath you.
