Answering Your Questions at DockerCon LIVE 2021
Guest post by Docker Captain Bret Fisher, a DevOps consultant and the creator of the popular Docker Mastery Udemy course. Join us for DockerCon LIVE 2021 on Thursday, May 27. DockerCon LIVE for a free, one day virtual event at https://dockr.ly/2PSJ7vn
I have the pleasure of hosting many of the live events at DockerCon this year. You may remember my 7+ hour non-stop live stream from last year’s DockerCon LIVE 2020 with nearly 20 guests:
We’re back!
This year we’re calling them Live Panels. You’ll find them in their own track in the schedule.
If you’ve never visited one of my live streams before, they tend to be DevOps focused, and as practical and real-world as we can be. Come ready to ask my guests questions in chat on our selected topics, and we’ll do our best to answer as many as we can! You get to guide the conversation with the live stream chat Q&A.
I’m hosting three live panels on three topics. I wanted to discuss the top three things that I think are the hottest topics in Docker and Cloud Native container tech today for developers and DevOps professionals, so be sure to stop Continue reading
How Upgrading PHP On WordPress Became *It Was DNS*-An IT Operations Tale
The server needed a PHP update. WordPress told me so with a severe-sounding notification adorned with red coloration, a security warning, boldface type, and a link explaining how to change the PHP version. I sighed. Security issues never end, and I have a recurring reminder in my todo list to patch the Virtual Private Server (VPS) boxes I shepherd.
But this PHP issue…hmm. This felt like a bigger deal, and many sites I support lean heavily into WordPress. Rather than wait for the next regular patching session, I decided to get on it. I did a process test on one server, a lower profile machine that wouldn’t hurt too much if things went awry. The goal was to move from PHP 7.2.insecure to PHP 7.4.secure. How hard could it be?
Most of the search engine hits for “upgrade PHP on WordPress” told me to go into CPanel or a similar tool my hosting provider might offer to abstract what’s going on with the server itself. That’s not what I was looking for, because I manage my own hosts. I needed to know how to reconfigure the host itself. The OS packages to install. The conf files Continue reading
Day Two Cloud 098: Cloud Centers Of Excellence – Should You Have One?
A fractured cloud strategy causes headaches such as duplicated services, unnecessary costs, poor security controls, and other problems. A cloud center of excellence can reduce the pain by developing and championing best practices, socializing adoption, and addressing inevitable exceptions.

The Hedge 84: David Brown and the Root of Trust
Many engineers just assume that secure hardware boot is, in fact, secure. How does this security work, and just how secure is it, though? David Brown joins Tom Ammon, Eyvonne Sharp, and Russ White on this episode of the Hedge to discuss the secure boot loader in some detail. For more information on the secure boot loader and IoT, see David’s presentation at the Open Source Summit.
Talking Chip With Ampere Computing CEO Renee James
Outside of the HPC market where there are a number of companies that have delivered or are working on Arm-based server processors, Ampere Computing is the main independent supplier of Arm-based server chips with its current 80-core Altra chips and its impending 128-core Altra Max chips, which are sampling now and will start shipping in the third quarter. …

Fun with private Automation Hub – Part 1
With the introduction of Ansible Automation Platform 1.2 at AnsibleFest 2020, Ansible released private Automation Hub. This enables a means to deliver, manage and curate Ansible Automation Platform Certified Content via a central on-premises, self-hosted solution for use by internal automation communities.
This sparked my interest in digging deeper into what private Automation Hub is and how I could leverage it. My initial perception went from a mysterious black box to viewing it as the perfect Ansible Automation Platform sidecar.
I learned quite a bit on how I could optimize it for my environments and wanted to share my findings. Before we start, a brief history of Ansible content and Ansible Content Collections may be helpful.
"Following the light of the sun, we left the Old World." - Christopher Columbus on Ansible Collections
During 2017, the number of modules, roles and content under Ansible's GitHub repository surged. The backlog of issues started to increase as the inflow of new content for different platforms and network appliances/devices outpaced the growth of the Ansible Core team. Various YouTube videos and blog posts provided commentary and insights from the Ansible community. The rapid growth of Ansible content led to the birth Continue reading
Back to Basics: Unnumbered IPv4 Interfaces
In the previous blog post in this series, we explored some of the reasons IP uses per-interface (and not per-node) IP addresses. That model worked well when routers had few interfaces and mostly routed between a few LAN segments (often large subnets of a Class A network assigned to an academic institution) and a few WAN uplinks. In those days, the WAN networks were frequently implemented with non-IP technologies like Frame Relay or ATM (with an occasional pinch of X.25).
The first sign of troubles in paradise probably occurred when someone wanted to use a dial-up modem to connect to a LAN segment. What subnet (and IP address) do you assign to the dial-up connection, and how do you tell the other end what to use? Also, what do you do when you want to have a bank of modems and dozens of people dialing in?
