Video: podman systemd-based system containers with GUI Desktop

Submitted by Scott Dowdle on Sun, 11/01/2020 - 17:24

In this screencast I show how to build a podman image using the Fedora 33 base image to include httpd, mariadb, openssh-server as well the XFCE desktop environment with a sampling of desktop applications.  I then make and run a container with the image and show you how to connect to it with ssh, http, and X2Go.  Oh, and I do all of it as a regular user... as a rootless container.  The POWER of podman.  Obviously watch it in full-screen or download. Enjoy!

For information on how to convert a podman container into a systemd service flle that can be managed with systemctl... even as a user service... see this fine video: Managing Containers in podman with systemd Unit Files

Here's a fine article by the master (Dan Walsh) that discusses rootless containers for anyone who might want more info.

Video: CentOS 8 XFCE / zram swap screencast

CentOS 8 only provides the GNOME Desktop.  What if you want XFCE?  EPEL has it.  What if you want to access it remotely?  x2goserver is your friend.  What if you are on a Digital Ocean Droplet and don't have any swap?  Use zram swap.  Enjoy.

BTW, the same recipe works with Fedora... just using stock repos. zram-swap is going to be on by default in Fedora 33... but probably not in the Digital Ocean Droplet image.

According to wikipedia, DevConf.CZ is...

an annual, free, Red Hat sponsored community conference for developers, admins, DevOps engineers, testers, documentation writers and other contributors to open source technologies. The conference includes topics on Linux, Middleware, Virtualization, Storage and Cloud. At DevConf.cz, FLOSS communities sync, share, and hack on upstream projects together in the beautiful city of Brno, Czech Republic.

There were a lot of fantastic presentations at the 2020 conference held back in January... and 212 of have been posted to YouTube.

As a sample, here's Dan Walsh updating us on the State of Container Security.  Enjoy!
