podman logo

By Brent Baude GitHub

If you follow the traffic on IRC (#podman on libera.chat) or GitHub from the developers of libpod, you might have seen us referencing a new API. We often referred to it as apiv2 and for about a month, there has been an 'apiv2' branch for libpod on GitHub. This week, we have begun to merge that branch but have yet to “wire it up.”

First and foremost, the Golang libpod API remains largely unchanged. What is changing is the API we expose for automation and remote usage. Our previous API was based on the varlink protocol. But we heard from users that varlink was a hurdle for libpod adoption especially for those who were using the Docker API and its bindings. They simply could not or did not want to rewrite their custom applications for libpod’s new, varlink-based API.

Building freely distributed containers with open tools

By Tom Sweeney GitHub

Scott McCarty (@fatherlinux) has an amazing video on YouTube about Building freely distributed containers with open tools. As only Scott could say "Although explaining how to ride a Tron-style light cycle is beyond the scope of this tutorial, we will discuss something almost as exhilarating—building containers with #Podman and #RedHat Universal Base Image (UBI). We will cover how to build and run #containers based on #UBI using just your regular user account—no daemon, no root (rootless), no fuss. Finally, we will order the deresolution of all of our containers with a really cool command. You probably won’t be promoted to CEO of ENCOM after this talk, but you will have new tools in your toolbelt for how to find, run, build, and share container images."
