This week includes kpod, vagrant-buildah, Fedora Atomic Host, CentOS Atomic Host, Kubernetes containers, and more.

New CentOS Atomic Release and Kubernetes System Containers Now Available

Last week, the CentOS Atomic SIG released an updated version of CentOS Atomic Host (7.1707), a lean operating system designed to run Docker containers, built from standard CentOS 7 RPMs, and tracking the component versions included in Red Hat Enterprise Linux Atomic Host.

The release, which came as part of the monthly CentOS release stream, was a modest one, including only a single glibc bugfix update. The next Atomic Host release will be based on the RHEL 7.4 source code and will include support for overlayfs container storage, among other enhancements.

Buildah Blocks — Getting Fit

Like many other Americans, I am fighting the battle to stay fit and I’m not always winning. Staying fit can also be a problem in the container environment. A common problem people have with building container images with tools like Dockerfile and the run-time-based docker build command is the size of the image, as well as the number of build tools that end up inside of it. Another concern about these unnecessary tools is they can weaken your container by opening potential venues for hackers to take advantage.

A really nice feature about Buildah is you can strengthen your container making it “stronger and more fit”. By finely tuning the creation of the container, and then adding or removing pieces as you desire, you can control the size of your container and lessen its vulnerabilities. It’s all under your control.
