DevNation Deep Dive - Telco edition

Build your application on RHEL across infrastructure footprints lets you manage applications and services using the same tools across locations.

DevNation Deep Dives

Deep Dives are one-hour, LIVE events that dive into the fundamentals of developer technology. Each session comes with live code and commands, and live chat Q&A with verbal responses from the speakers.

Linux I: March 14 at 9:00 am. CET (Kevin Dubois)

Linux II: March 30th at 9:00 am. CET (Natale Vinto)

Containers: April 13th at 9:00 am. CET (Hans-Peter Grahsl)

Quarkus I: April 27th at 9:00 am. CET (Kevin Dubois)

Build your application on Red Hat Enterprise Linux (RHEL) cross infrastructure footprints lets you manage applications and services using the same tools across locations. After finishing Linux I and II Deep Dives, you will be able to master basic and intermediate usage of Linux, including basics of file management, installing software, using terminal multiplexers/code editors, and building a container image and running it from the RHEL 9 Universal Base Images (UBI).

Session abstracts:

Linux I

In today’s world, certain core technologies are critical to learn as they’re a foundation for much of what we use today. Linux is a prime example and is a successful platform that enables virtualization, the cloud, containers, and so much more.

Let’s take a dive into the world of Linux with this first session of the DevNation Deep Dive Telco Edition. Join Kevin Dubois in this one-hour session which will be held on March 14 at 9:00 am, and get a quick overview of some Linux topics you may run into when spinning up new applications or containers on Red Hat Enterprise Linux.

Linux II

Join Natale Vinto to continue to dive into the world of Linux, with the second stop of the DevNaton Deep Dive Telco Edition taking place on March 30th at 9:00 am.

By the end of this talk, attendees will have a better understanding of:

Editors [vi, nano, cat -vet]

How to find and kill a process [ps, grep, kill, kill -9]

Gathering some OS stats [ip a, os-release, top, iotop, ss, df -hP]

Looking at open ports [nmap, /etc/services]

Fancy ssh (ssh, scp, sftp, ssh-copy-id)

Quick SELinux overview setenforce, semanage, setsebool, ls -Z, [https://stopdisablingselinux.com

Is your Java app consuming the server’s whole memory and taking minutes to boot? And then, even more time to redeploy? Get rid of your 25-year-old Java jokes and join Kevin Dubois as he shows you how to use Quarkus, the supersonic, subatomic Java, in this one-hour, deep dive session which will be held on April 27th at 9:00 am CET.

What you will learn:

Quarkus setup

CRUD and RDBMS

JVM and native deployment

Custom configuration

Quarkus deployment to Kubernetes/OpenShift

Spring compatibility extensions
