[TechStory]: Migrating services and databases from an OpenShift (or K8s) cluster to another
My first experience with OpenShift was with a task which was kind of a heavy task, I didn't know anything about OpenShift or K8s! but I was in charge of migrating resources from a cluster to one another! (twice!)

Collecting Security Logs
Openshift documentation can be hard to find, and installing an cluster without it can be hard. 🤗

My director is mad that I accepted another internal position for a 26% raise when he was told he could only give me a 10%
At your own pace, jump into orchestration using a Kubernetes distribution out there; but really, only do that fairly late in the game (e.g. OpenShift). Sadly, it's quite a jump from containers to orchestration, and there is no "smooth" in-between. Maybe as a prelude, you can look into etcd configuration clusters and Ceph storage clusters first, e.g. using a bunch of VMs on your machine, or a few Raspberry Pis. There are plenty of occasions to pinch your fingers with those, and thus valuable lessons to be learned :-)

OpenShift in a disconnected environment using vCenter - starting from nothing
Part of my job is to help document and assist with getting environment running offline, including OpenShift. While I don't use vSphere the general process is the same, while individual platforms may require different commands the concepts are all the same. Using docs.openshift.com you can find comprehensive guides in how you setup each platform Openshift supports "disconnected". But do realize that not all organizations agree on the exact definition of what disconnected means so you may need to adjust based on what you need. Some allow "sneaker net", others requires you to use old fashioned DVDs to bring all data onsite etc.

Best documentation/discovery process and/or tool for an existing Openshift environment?
You want to be able to rebuild your clusters in case of a disaster, so, any time you install anything, export the yaml. And read https://docs.openshift.com/ for every new version.

AWS Cloud Platform for highly loaded WordPress website
The missing piece of puzzle is the AMI "golden image" that will be used to start the instances in autoscaling group. The AMI has to have NGINX and PHP installed with the list of required modules enabled. The great tool to brew one is hashicorp packer.

The 2024 Web Hosting Report
To manage a VM, you can use something as simple as just manual actions over SSH, or can use tools like Ansible, Hashicorp's Packer and Terraform or other automations. For an app where there is minimal load and security/reliability concern, VMs are still a great option that provide a lot of value for the buck

13.2 ZFS root AMIs in AWS
It is straightforward to build them with packer (I have built AMIs for 13.0 and 13.1, but 13.2 should be exactly the same). I've been meaning to write a blog post about it for a while, but have not gotten to it yet... In any case, what I am doing is using the EBS Surrogate Builder to start an instance running the official FreeBSD 13.2 image with an extra volume attached and run a script to create a zpool on the extra volume and bootstrap and configure FreeBSD 13.2-RELEASE on it. After that packer takes care of creating an AMI out of that extra volume, so you can use it... If you have any issues, let me know, and maybe I will finally get to writing that blog post...

auto-provisioning multiple raspberry pi's
Packer is a tool that can be used to build machine images. Basically, it takes a base image, runs a series of steps to provision that image, and then burns a new image. In my workplace we use it heavily to build AWS AMIs. But it has an ARM plugin that looks to be very very suitable for building customised Raspberry Pi images (my quick read of the doco there says it can go ahead and write the final image to an SD card for you too).

How to create AMI which also copies the user data?
I'd suggest using a tool like Packer to build a gold image based on your base AMI and all your changes. Then you'll have your own AMI you can launch new instances with.
