Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

[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!)

DevOps Tooling Landscape
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.

Collecting Security Logs
Openshift documentation can be hard to find, and installing an cluster without it can be hard. 🤗
- How to keep OpenShift clusters running?

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

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.

Show HN: Bocker-compose, the missing layer to Docker-compose
A (joke?) one-liner I came up with while thinking about solutions to centralized container management across multiple SSH hosts. Shame on me.
The name is inspired by bocker [0], albeit this doesn't re-implement docker-compose in bash, I found it to be fitting enough.
I'd love to see someone come up with a smarter and/or shorter way to do this.

Barco: Linux Containers from Scratch in C
When I did a talk about docker I also wanted to show a bit of what it does under the hood without going through all the layers and without too much details. This ~120 lines of shell script is really good in providing just an intro into what's needed for containers: https://github.com/p8952/bocker/blob/master/bocker

Latest Zen Kernel......
i tried it and like the concnpt, but until it can be launched via a systemd userspace service (without previously manually booting it) among other problems i will keep using docker (or bocker)

The Staff Engineer's Path – Book Review
> But you couldn't reimplement podman in a few hundred lines of code.
You don't even need a few hundred: https://github.com/p8952/bocker
And then there's 'dokku' which IIRC, started as a bash version of Heroku.
> Not all ideas have the same quality.
They really do. I've heard all kinds of things in my career, but almost none I would want to dedicate a portion of my life building. Not because they are bad ideas or won't work, but because of the person with the idea or it just didn't interest me. Those people went on to be moderately successful (like hundreds of millions worth) but I'm glad I wasn't on that ride.

“Implement DNS in a Weekend”
Bocker is in this same category...docker clone in bash that's helpful in seeing what's really happening underneath with nsenter, namespaces, network bridging, cgroups, etc.

Ask HN: What is the best source to learn Docker in 2023?
Docker implemented in around 100 lines of bash: https://github.com/p8952/bocker
This is the most mindblowing example for enterprise security teams that think Docker is a new threat on a single tenant Linux host.
No, buddies, all this stuff is already there. If you were fine with your visibility before*, you're still fine. Go find a real problem while we play with our developer dopamine.
* NARRATOR: They shouldn't have been.

Containers are chroot with a Marketing Budget
Bocker[1] does a reasonably good job of showing the value of Docker was mostly in Docker hub.
[1] https://github.com/p8952/bocker
There is a cool project I've seen called "bocker" (https://github.com/p8952/bocker) which is something of a proof of concept of implementing Docker with bash, which speaks a bit to how Docker is indeed in many ways an amalgam of lower level primitives (such as chroot as you mentioned). Pretty neat!
