Unleashing the Power of Podman: A Docker Alternative | SLUUG 2024-11-13

MAIN: Unleashing the Power of Podman: A Docker Alternative
Presenter: Andrew Denner
Abstract: In part 2 of my containerization series, we will explore the advantages of Podman as a powerful Docker alternative.
This presentation will shed light on Podman's unique features, such as its daemonless architecture, enhanced security, and compatibility with existing Docker images.
We will also discuss how Podman integrates with system d, providing a more seamless and efficient container management experience.
Finally we will cover the ugly parts where there are still warts and room for growth.
BASE: When IPtables isn't really IPtables
Presenter: Lee Lammert
Abstract: After noticing a "Let's Encrypt" cert renewal failing recently, it was a tortuous path to actually identify the problem. I.E.- certbot (ie EFF's tool to obtain certs from Let's Encrypt) did not "see" the open port 80 visible in iptables -vnL! (vnL is iptables switches.)
Tune in Wednesday as we:
... revisit the troubleshooting process,
... what we found,
... and how we made it work properly.
