A Comparison of Linux Container Images

A Comparison of Linux Container Images

  Updated 06/02/2020 Understanding Container Images To fully understand how to compare container base images, we must understand the bits inside of them. There are two major parts of an operating system – the kernel and the user space. The kernel is a special program executed directly on the hardware or virtual machine – it

A Hacker’s Guide to Moving Linux Services into Containers

Background For years, I floundered around with moving my own blog, ticket system and wiki into containers. Literally, ticket #627: Migrate Crunchtools to Containers has been open in Request Tracker since March 11th, 2017. It’s embarrassing to admit given how deeply I have been involved with containers at Red Hat. Since the early days of

Deeply Understanding the Different Between Portability, Compatibility, and Supportability

Let’s dig into these three concepts a bit deeper: Portability Since the OCI standard governs the images specification, a container image can be created with Podman, pushed to almost any container registry, shared with the world, and consumed by almost any container engine including Docker, RKT, CRI-O, containerd and, of course, other Podman instances. Standardizing

The Limits of Compatibility and Supportability with Containers

Many folks who do container development have run Alpine container images. You might have  run Fedora, Red Hat Enterprise Linux (RHEL), CentOS, Debian, and Ubuntu images as well. If you are adventurous, you may have even run Arch, Gentoo, or dare I say, really old container images – like, RHEL 5 old. If you have some
