Had a hard time to get into K8S. I've installed Portainer and was satisfied with it. It has some limitations but I am fine with it.

Another tool I like is stern. It is for tailing logs. What I like about it is that I can use selectors to display the logs for all pods in a deployment and use since so get just the most recent logs while tailing. Don’t know about newer version of kubectl but it wasn’t able to do all three at the same time the last time I tried and now use stern exclusively.

@@ThePapanoob You may be able to now but in the past I was not able to use ‘since’ and ‘follow’ together which meant I had to wait as it scrolled through all the logs to get to the end. It wasn’t just the time but it also cleared the scroll back buffer on my terminal. Another feature I like is that it prefixes each line with the pod name when displaying logs from multiple pods. If you like kubectl, stay with it since sticking with one tool is a lot easier. I wasn’t. Also stern is not the only third party tool for looking at Kubernetes logs. Just the fact that there are alternatives implies that kubectl is less than optimal for many people.

Thanks!

We have rancher installed at work , it's quite a complex system the only thing that i don't like it's how bloated the cluster becomes once installed but that's probably because we are not using it as they recommend it, and that is to have your management cluster where rancher is installed and have separate workload clusters :)) , we also have it integrated with our Google Workspaces account but will probably switch it to Active Directory

Infra App so cool

I’m using rancher for manage my EKS cluster 😅

Lens the best!

Pity Lens is not being offered with a tablet/smartphone platform in mind as well, the download section only lists MS exes, linux rpm/deb/appimage/snap and macos dmg... while dropping the graphical UI from the cluster to a desktop app releases the resources on the nodes for actual work, users typically want to be able to use/monitor/manage the cluster from any device. If the UI is baked in into the kubernetes distribution or the node OS, you only need a device with a browser to work with the cluster.

VSCode have nice features.

Longhorn has a very major flaw … if you have a power outage. When the pods come back up they don’t auto fsck. You might need to fix every single volume manually with an fsck -y, they don’t do this for you automagically. I wrote a cronjob to just look at syslog and auto repair any volumes that show up requiring an fsck on mount (as long as they are longhorn volumes)

IMO, Rancher is just too buggy for long term usage. I use it for years and every year ran into major problem and have to rebuild my cluster from time to time. I ended up dropped it for my homelab setup

What do you use as your terminal client ?

OpenLens > Lens None of that Mirantis commercial crap packaged into it. No forced account creation, etc. We use OpenLens at work, it just hooks kube config, and AWS EKS cli just adds cluster and user profiles to kube config, so it picks it up just fine. Not sure why you would need AD integration with OpenLens when OpenLens is not an auth mechanism itself, it just hooks existing mechanisms through kube config. Unfortunately, there are no "official" builds of OpenLens since Mirantis bought/funded the OpenLens team, as Mirantis obviously doesn't want to undercut their commercial product. You have to do a little bit of searching for how to build or install 3rd party builds of OpenLens.

K9S is the best!

Its worth to mention TILT. Super tool for automating development process

I have been using K9S at work were I don’t have WUI or GUI and really like it. I don’t think that the lack of ability to create resources as a drawback. I have been frustrated with tools like Portainer that “own” your resource definitions. Once you create the resource using their tool, you can’t export it and use it outside of their tool. I use Portainer at home but never to create or edit my resources so I own my configuration.

@@borntoexcel14 I don’t create resources with K9S or Portainer. At home I don’t worry about supporting multiple environments so a simple YAML file with related resources works well. I also experimenting with Ansible for Docker. At work I am working with deployed resources. The biggest differences are in configuration/secrets and scale. I have tried Terraform and CloudFormation. Currently we are using Jenkins to provide environment specific properties. As a developer I find it very enjoyable to come up with complex solutions but in the end, they don’t add value. They just add complexity that you need to deal with in the middle of the night. The other issue with complex solutions is that no one else wants to touch it so you own it and can’t move on to new projects.

* Better lifecycle management than just docker alone. Deployment/Statefulset upgrades are "built-in" to some extent and can roll-back if not successful. * Helm charts are available for most software that is already containerized * Much better ingress handling for multiple services vs just a self-managed reverse proxy * Cert-manager automatically will generate and renew certs (incl LetsEncrypt) for your web services, just "enable" SSL on the ingress * external-dns can automatically create/update/delete DNS entries for your web services, either locally (such as a LAN DNS server), or externally (such as CloudFlare or some other service). * Can ingress, secure, and proxy traffic to other web services outside of the cluster, but using the cluster to manage access to those web services centrally. Ergo, you have another web server thats not running in kubernetes, but can use an ingress, service, and manually created endpoint, to point to that and have it all SSL and DNS automated via aforementioned tools. * Kubernetes at its core, is a state engine, so it will do everything in its power to maintain that state. Liveness probes, readiness probes (readiness determines availability for receiving traffic, vs liveness means its running, but not dead), restart containers when things aren't responding or crashing. * Could setup HA cluster, even on a single bare metal machines using VMs, so that you can have an "always up" path for updating the cluster. Not redundant, but hey, something. * Could setup HA cluster on things such as raspberry pi quite cheaply. * Can define your home environment and services more agnostically to what is actually running kubernetes. Setting up a kubernetes cluster can be a fairly straight forward process and runs on just about anything. You could back everything in a git repo, then redeploy your entire setup from scratch this way within just a few steps if you had to. * More storage options and redundancy out of the box with kubernetes storage providers than with something like docker alone. * You learn how to properly setup, manage, and upgrade a Kubernetes cluster, which can get you jobs paying $180k+ with no degree, as even the concepts in a home lab scale on Kubernetes. * I am sure there are several more points that could be made, but these were just the ones off the top of my head.

There is also fish shell and other fish like extensions for other terminals (zsh etc) that arent dependent on specific terminal emulator, but not quite as fancy either. It will inline hint out suggestions or history, depending on how you have it configured. if you are using kubectl, make sure you setup kubectl autocomplete for the shell you use. zsh/oh-my-zsh has autocomplete plugins for kubectl that will query the k8s api and autosuggest things relevant to your current cli query. ergo, if you are typing "kubectl exec -it " and double tab, it will discover the pods in the current contexts namespace, and suggest them for you for autocompletion.
