"Building an Ephemeral World" - Steven Ellis (LCA 2022 Online)
(Steven Ellis) We’re seen a seismic shift in recent years from long lived compute environments to ephemeral short term workloads, be they cloud based virtual machines or containerised instances. This changes not only how we provision and deploy workloads, but also our approaches for applying updates and security patches.
This session will look at two different approaches for creating our standard images.
ImageBuilder for our traditional Linux Images
Buildah for our container images.
ImageBuilder, based on the osbuild-composer project, allows you to create custom Linux system images in a variety of formats, and is compatible with a broad range of Cloud and Virtualization platforms. Today it can also be used to define specialized images designed for deployment on edge devices.
Buildah ‹https://buildah.io› aims to be a drop-in replacement for the “docker build” process for container creation, whilst exposing a smaller attack surface and can support rootless builds. It creates OCI compatible container images
We’ll look at the strengths and weaknesses of these two tools and how they compare with alternatives, some steps for maintaining secure images, and looking into their roadmaps.
