openshift-docs VS hyperconverged-cluster-operator

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!)

OpenShift is a container platform from Red Hat that's built on top of Kubernetes. It offers additional features like built-in CI/CD pipelines, enhanced security, and support for multiple programming languages and frameworks.

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

For whatever reason, the PRs for adding CloudWatch and Loki/Vector to the docs haven't merged yet.

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 :-)

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.

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.

- We are adding CNV docs to OKD

- We successfully tested OKD 4.8 installation on bare metal UPI with HyperConverged Cluster Operator (HCO) . We published a guide for it here: Guide to installing OKD Virtualization on Bare Metal UPI we'll move the docs as well as soon as we get the subgroup pages into the main OKD.io site.
