SKA Base Images

This repository contains the definition of the base image that’s deprived of application level dependencies for SKAO developers to use as a base image when building their own products or other variant base images.

This will make possible to create and release a security patched Ubuntu 22.04 base image without any application dependencies and to implement a monthly security patch process for all ST services and images.

Currently, we provide the following images:

• ska-base: CIS hardened Ubuntu 22.04 base image

• ska-base-ubuntu24: CIS hardened Ubuntu 24.04 base image

• ska-base-ubuntu26: CIS hardened Ubuntu 26.04 base image

• ska-python*: slim single-version Python runtime images

• ska-build-python*: multi-version Python build and CI images

• ska-node*: slim Node 22 runtime images, one per Ubuntu base

• ska-build-node*: Node 22 build and CI images, one per Ubuntu base

• ska-webserver: Nginx-based static webserver image (Ubuntu 26.04)

• ska-cuda*: NVIDIA CUDA runtime and build images
