Using Podman and Docker Compose

By Brent Baude GitHub​

One of the questions that the Podman development team has been hearing a lot over the past year or so is "Does Podman support Docker Compose? Up until recently, the answer was "not yet". With the soon to be released Podman v3.0, that answer changes to "NOW!" Brent Baude explains the how to in a recent blog post on the Red Hat Enable Sysadmin site, Using Podman and Docker Compose. This functionality is now available in the upstream version of Podman if you want to take a real sneak peak.

Como está o seu português? Well if it's better than mine, check out Daniel Lara's video on YouTube. He walks through running Containers using Podman, creating pods, generating YAML for Kubernetes and more! Daniel uses a number of great examples, so it is pretty easy to follow along even if your Portugese is like mine. Apreciar!

Robert Bohne has a nice post on opensourcers.org which talks about the basics of containers, how digests and manifests come into play, working with and creating multi-architecture images and more! It is a really nice discussion of all the pieces and parts of a container image for someone new to the technology right through people who are a lot more experienced, but might not know every nook and cranny.

A Podman API v1.0 and libpod.conf Removal Notice has just been posted. The Podman v1.0 API based on the varlink library and the libpod.conf file have both been removed from upstream Podman. Please see the notice for more details.

Podman API v1.0 and libpod.conf Removal Notice

By Tom Sweeney GitHub​

On August 1, 2020, the Podman team posted a Podman API v1.0 Deprecation and Removal notice. As noted in that document, the Podman API v1.0 relied on the varlink library to handle the underlying client/server calls from the Podman client to the host where the Podman service was running. The support for the varlink library was greatly reduced in the spring of 2020. This led the Podman team to investigate the use of other client/server technologies and it was decided to develop a RESTful API for Podman using the native Go libraries.

Ed Haynes has put together a demo of using Podman and systemd to manage a container lifecycle that's available on GitHub. He's written up a post that does a nice job of walking through setting up the demo and running it.

Using Podman and systemd to manage container lifecycle

By Ed Haynes GitHub​

My background is in industrial automation, and in most cases, the edge devices in the factory are too underpowered to run Kubernetes as a method to manage the lifecycle of containers. The workloads have a very long lifecycle, and generally are "tied" to the edge device. There is a lot of value in containerizing applications on these edge devices, however, as it decouples the application dependencies from the OS and provides a level of isolation between applications. This demo will show how using Podman in conjunction with systemd provides an elegant solution for this sort of use case. In addition, this will be done as a "rootless" user - a key benefit of Podman that helps keep the device secure.

I've run across a number of posts over the past few weeks concerning Podman and have been busy getting other work done. So now I have a few moments and thought I'd add some links to the posts. Checkout the Podman Posts of Interest for the links!
