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.
Wander, a terminal app for HashiCorp Nomad

 https://github.com/hashicorp/damon4 projects | reddit.com/r/golang | 4 Jul 2022
OP here. In my experience, Nomad is a joy to use, but the tooling around it is less mature than that of Kubernetes. In the spirit of k9s and damon, Wander is a terminal application for observing and interacting with Nomad clusters. Wander allows users to view jobs, allocations, logs, specs, and exec in and run commands in running tasks. The terminal UI/UX is designed for maximum efficiency and information density. Wander also comes with an ssh server via “wander serve”, so for example, one could deploy it within an internal network such that engineers can ssh in and start a wander session without having to install or configure anything. Wander is built on the excellent tools provided by Charm, namely, Bubble Tea and Wish.  https://www.nomadproject.io/  https://k9scli.io/  https://github.com/hashicorp/damon  https://charm.sh/

Looking for something like Lens but for Nomad

Closest thing I know of to Lens is damon. It's a TUI though.
The checklist: Monitoring for Economy

There are many ways you can see if instances are underutilized, using some open source tools such as k9s cli or Lens (if measuring the utilization of VMs which are part of Kubernetes clusters). Or the cloud providers console to see the memory and compute consumption of the provisioned VMs.

> Git as a version control system is great, but it desperately needs an "apt style" revamp.
I'd say that this is one of the reasons for why many prefer to use either integrations with their IDE, or graphical tools like SourceTree, GitKraken or even something more basic like Git Cola.
Personally, I also fall into this camp: and if I need to do something "fancy", then it's quite likely that I've diverged from the usual "happy path" too far and should rethink my approach (and if necessary, then just drop down to CLI after some googling). Of course, there are various camps in regards to all of this, but being able to stage/unstage individual code chunks/blocks and spread out/group changes that have already been done in files over multiple commits feels like a nice quality of life improvement. Plus, the diffs that something like the JetBrains IDEs show you, as well as the ability to look at the history for a particular selection is also nice.
Then again, there are also many who don't rebase their branches, or even don't select squashing merge commits in whatever UI they might use (e.g. using GitLab/GitHub for their code review functionality and other features), which some might dislike for any number of reasons. I guess that just shows that there are many different workflows and people flock to whatever they feel comfortable with (or whatever their org/team mandates).
As for the actual CLI, in general there are few programs out there that actually feel good and usable to me, one of which is the Docker CLI (for the most part). I actually compared its discoverability/usability to something like tar previously here: https://news.ycombinator.com/item?id=29339018

The Container Orchestrator Landscape
8 projects | news.ycombinator.com | 24 Aug 2022
This seems like a pretty well written overview!
As someone who rather liked Docker Swarm (and still likes it, running my homelab and private cloud stuff on it), it is a bit sad to see it winding down like it, even though there were attempts to capitalize on the nice set of simple functionality that it brought to the table like CapRover: https://caprover.com/
Even though there is still some nice software to manage installs of it, like Portainer: https://www.portainer.io/ (which also works for Kubernetes, like a smaller version of Rancher)
Even though the resource usage is far lower than that of almost any Kubernetes distro that I've used (microk8s, K3s and K0s included), the Compose format being pretty much amazing for most smaller deployments and Compose still being one of the better ways to run things locally in addition to Swarm for remote deployments (Skaffold or other K8s local cluster solutions just feel complex in comparison).
And yet, that's probably not where the future lies. Kubernetes won. Well, Nomad is also pretty good, admittedly.
Though if you absolutely do need Kubernetes, personally I'd suggest that you look in the direction of Rancher for a simple UI to manage it, or at least drill down into the cluster state, without needing too much digging through a CLI: https://rancher.com/
Lots of folks actually like k9s as well, if you do like the TUI approach a bit more: https://k9scli.io/
But for the actual clusters, assuming that you ever want to self-host one, ideally a turnkey solution, RKE is good, K0s is also promising, but personally I'd go with K3s: https://k3s.io/ which has been really stable on DEB distros and mostly works okay on RPM ones (if you cannot afford OpenShift or to wait for MicroShift), with my only pet peeve being that the Traefik ingress is a little bit under-documented (e.g. how to configure common use cases, like a SSL certificate, one with an intermediate certificate, maybe a wildcard, or perhaps just use Let's Encrypt, how to set defaults vs defining them per domain).
For the folks with thicker wallets, though, I'd suggest to just give in and pay someone to run a cluster for you: that way you'll get something vaguely portable, will make lots of the aspects in regards to running it someone else's problem and will be able to leverage the actual benefits of working with the container orchestrator.
> To extend its reach across multiple hosts, Docker introduced Swarm mode in 2016. This is actually the second product from Docker to bear the name "Swarm" — a product from 2014 implemented a completely different approach to running containers across multiple hosts, but it is no longer maintained. It was replaced by SwarmKit, which provides the underpinnings of the current version of Docker Swarm.
On an unrelated note, this, at least to me, feels like pretty bad naming and management of the whole initiative, though. Of course, if the features are there, it shouldn't be enough to scare anyone away from the project, but at the same time it could have been a bit simpler.

Falling for Kubernetes

For anyone managing a k8s cluster and are fatigued with memorizing and reciting kubectl commands should definitely take a look at k9s. It provides a curses like interface for managing k8s which makes it really easy to operate and dive into issues when debugging. Move from grabbing logs for a pod to being at a terminal on the container and then back out to looking at or editing the yaml for the resource definition in only a few key presses.
