Monitoring containers and clusters in Kubernetes is essential for ensuring the best performance in applications. This week’s issue will be focusing on the importance of Kubernetes monitoring and some issues that come with using monitoring tools for Kubernetes.

This week we’ll be investigating Kubernetes secrets, to discover the best and useful tips and tricks for any K8s developer. Warning ahead: There are Kubernetes Secrets found!

This week we’re looking into Kubernetes failures and incidents. As you might imagine, these issues can have a nasty impact for users, and where recovery plays the most critical role.

To avoid exploitation and the delivery of malicious bugs in Kubernetes, it is critical that your system is secure and containers are kept closed. Some of the most damaging attacks can lead to every pod and container to shut down and break. Security is vital, and that is what we will be looking at today.

Today, we’re opening common networking issues within Kubernetes. Let’s take a look at what Kubernetes Networking is dealing with, to specific issues within K8s. And solutions too.

We also are taking a look at Container to Container, Pod to Pod, and External to Services Networking!

Helm is a package manager tool used for Kubernetes. Known for managing complex apps and easy rollbacks, Helm is quite popular. These articles answer questions like “What is Helm? How do I use it?” Is it the best tool for Kubernetes? And of course, a Helm tweet.

Kubernetes has many things to offer when diving into it as a beginner. This week we look at a few in-depth Kubernetes related posts that include the environment, Docker, and Kustomize.

This week we also take a look into practicing with Kubernetes.

Entering the world of Kubernetes can be a bit scary at first, but hold on, buckle your seatbelt in and don’t be worried! Learning this open source software is quite interesting. This week we look at some posts that introduce Kubernetes and addresses the who, what, where, and why.

It’s amazing how much security content is produced in an around Kubernetes. This week we look at a few security-related posts but it's interesting to stop and consider where Kubernetes is in terms of supporting highly secure development workflows and production operations.

This week we also have a look at the ClusterAPI, Tooling and HAProxy 2!

This week we talk about security (pod security policies, TLS, honeypots), what’s new in the Kube with 1.15, and Apple joining the CNCF

Check it out!

This week we bring you articles on Kubernetes failure stories, managing permissions, and recovering from disasters with a few more goodies herein.

Kube sprawl is an interesting one, what incentivizes folks creating more and more clusters with more and more config on and on and on to power their Kubernetes journey? Some say it tenancy, Some say performance, read here to find out more.

This week we look at Kube sprawl, configurable HPA, Multi-Cloud clusters, Kube testing, and more.

Lots of cool outcomes from Kubecon EU: OpenTelemetry, Service Mesh Interface, ect.

We’ve collected a few recaps and some more around service meshes, the kube future, secrets, and scaling!

Actually not much in the way of spectacular content coming out of Kubecon yet - so maybe this is a part 1 of x.

Valero 1.0, Helm 3.0, Rook 1.0, OpenTelemetry!

Let's dive in and see what came out of Kubecon Europe and more!

Thank you to @CormacJHogan for your stateful take on things 😁.

Wonderful week in Kubernetes world on the eve of Kubecon Europe.

Hopefully, the following articles about newtype autoscaling, HA clusters, PKS, istio, and more get you super excited.

Read below!

Welcome welcome to an exciting week in Kubernetes.

Notably, the continued hype of k3s and the release of Kubernetes Based Event Driven Autoscaling are quite exciting developments in the Kube community. This week we check up on those, get into some questions on YAML dependencies, Networking / Service Meshes, and more.

Read on!

Hello, aren’t you excited that it is Kubecon Europe month?

This week we will pump you up with articles covering monitoring, resources, secrets, logging and more! Take your pick and really dig in to an area of the Kube that you find fascinating.

This week we return to regular schedule programming. An awesome week in Kubernetes land. The world of k8s is moving along. We found some juicy articles that you will want to sink your teeth in: Ingresses, Operating Systems, Migrations, and A N T H O S. Enjoy!

Today we are ending our series on Kubernetes Resources with a final part on Vertical Pod Autoscaling. We started the series looking at resources, what they were and how they were used and asked what autopilot for Kubernetes would look like? Are we there yet? How much effort will it be?

There are not that many resources on Vertical Pod Autoscaling, especially not its use in large scale production environments. But the material that is out there is great, check it out.

P.S. A little article on Helm included to spice things up.

Hello and welcome to the Horizontal Pod Autoscaling issue again!

There were soooo many great HPA articles that we had to do another. This time we are focusing on external and custom metrics, how to use them - why use them and more. There are a couple more goodies in here like Canary Analysis and how to be Overcommitted, the right way.

Read and enjoy!

Hello and welcome to the Horizontal Pod Autoscaling issue + Kubectl productivity!

This might actually be Horizontal Pod Autoscaling Issue part one because when we looked there were over 41 articles that were super cool to include. We put together articles that went beyond the standard fare of setting it up and using it from Control theory to Auto Scaling on Memory with JVM containers. Enjoy!

Hello and welcome to the second part of our series on Kubernetes resources!!

This week we bring you autoscaling all together, a bunch of articles on using the autoscaler (and related addons) together. This issue will serve as an intro to the history and practice of the autoscalers in general before we dive deep into each one.

Happy reading!

P.s. Tweet back at us your guess about which autoscaler we are going to write about next.

We are starting a new series at Kubelist this week: Kubernetes Resources and Autoscaling. We are going to be taking a little break from aggregating new content and curate some lists based on things we think are important to know for Kubernetes. (If you're really hungry for the newest stuff check out: or @kubeweekly).

This week we bring you Resource Management from the basics to advanced. These articles answer: How are resources managed in Kubernetes? What is utilization? What is isolation? How do my pods get scheduled? Why do my pods get killed? And the essential wisdom of Kubernetes resource management: Always set resource and limits.

Kubernetes, you want to know what’s cool about you?

Well, there's lots. But one thing is the number of people who use you programmatically by writing code and using code. Whether it's operators or tooling, you’ve really captured our developer hearts.

P.s. If you haven’t already, check out the Kubernetes WG LTS Survey.

As Kubernetes matures more cost savings and optimization endeavors are popping up – and this will only grow with wider K8s adoption. Specifically in this issue we have and KubeADM-AWS; in addition to some general K8s knowledge and a neat little kubectl plugin by the name of rakess. I welcome you to dive in and enjoy!

As Kubernetes and microservices reshape the landscape of modern computing, we’re seeing businesses placing big bets - especially in enterprise. Read on to find out how IBM and Intel are leveraging Kubernetes for hybrid integration and machine learning. We also have something to help businesses make sound decisions as they adopt Kubernetes, a really great tutorial for developers looking to start learning, and a glimpse at the future of CD pipelines.

That is not actually a question. You definitely have to config in Kubernetes. This week we have collected a bunch of recent articles on configuration management, security tooling, and more to help you think through your current kubernetes practice. A special treat this week is Lee Brigs. Why the fuck are we templating yaml? Which is well supplemented by background in The State of Kubernetes Configuration Management: An Unsolved Problem.

K8s is a great tool, but tools that make using K8s easier are even better. In this week's issue, we'll introduce a few tools that can improve your workflows for managing K8s resources and managing secrets. If you are feeling inspired by the end, the last article goes through how to write your own kubectl commands - so maybe you can write one too!

As our clusters grow in complexity and load, we start to question everything we thought we knew. Don't worry, we've got your back (and our own). This week we bring you some insights into scaling as you grow, a look inside of a truely large cluster, how to think about just hosted services, and finally, some great news from Apache Spark.

Kubernetes is meant to liberate and empower, not confuse and bog us down. Keep that in mind as you look go through this week's issue.

We want you to feel gr8 about your K8s all year long. As such, we've pulled together a collection of articles (and a podcast) to help you get your head in the game. Kubernetes is really fun (building operators), even when it fails... or at least when we get to learn from other peoples failures 🤷. We've also included some Istio learnin' to really help you level up.

Happy reading! (and listening, in this case)

Ch-ch-ch-ch-changes! This week’s batch of articles makes one thing clear: the rate of improvement, innovation, and continuous change in the Kubernetes community is nothing short of astonishing. This issue is a must-read to see what’s happening with security, discover tools for solving problems that most of us will have, and even learn how to make changes to Kubernetes itself. All aboard!

Ahoy! Today our love of the ocean and all things nautical is in full force. We apologize in advance if this issue heads into the depths of nautically inspired k8s talk. Be prepared for a whole new level of boat-themed puns.

We welcome you to 2019 with 'a year of kubelist', showcasing the most popular news and updates of 2018. If you haven’t read these yet, statistics says you should. They also say the following about Kubelist:

  • We gave away approximately 4,023 Kubelist stickers at conferences.
  • We reached the 1,000 subscribers mark and had a pizza party.
  • We had more than 5 editors contribute this year.
  • We spotted 4 laptops with kubelist stickers on them (and they weren't ours).

What a great year. We wish you the best in 2019.

You’re at home now for the holidays, all filled up from your trip to Kubecon. You’re quietly drinking eggnog and coffee mixed together contemplating what open source project you are going to work on for the next 12 days… a new controller to do that deployment thing you do 5 times a day, or perhaps contributing to the horizontal pod autoscaler? So many choices. Why don’t you take a break from your open source holiday anxiety and have a little read. We’ve got everything from AI to video games to an interview on the state of the Kube.


It's announcement season in the Kubernetes world, as KubeCon is the perfect time for companies to show off and gain exposure. We take a look at a number of things that caught our eye this week, while our secret agents were walking around the conference floor leaving Kubelist sticker trails behind them.

This week we found a few early Christmas presents under the tree that we're excited to share with you 🎄🎁.

New features from Microsoft along with some other tech influencers, cluster API stories, a bunch of awesome how to’s, and of course the greatest gift of all — version 1.13 of Kubernetes. Merry K8s-mas!

This week Envoy joins the ranks of Prometheus and Kubernetes as a CNCF Graduate. This is big and important news, but it's also a great excuse to link to Vitamin C.

As Envoy ventures out into post-graduation life, we take a look at why this newsletter will make you 173% more attractive as a job candidate. Enjoy! ☸️📈

There are many reasons to be thankful for kubernetes, but for the purposes of today's issue, we’ve narrowed it down to 6 reasons why we love this container-orchestration system 🙏

We hope you’re wearing your stretchy pants because we have 6 servings sure to please your K8s palate: cross cloud kubernetes, debunking common misunderstandings, container runtimes & more. Dig in!

The rise of K8s paved the way for more innovative ideas in enterprise infrastructure, for various fields. People are craving DevOps for Big Data. Some are using K8s to build a new OS for the age of AI, others are building awesome IoT Cloud services on K8s, while the rest are figuring out ways to improve enterprise K8s integration.

K8s-related acquisition alert 📣! VMware is now a proud owner of Heptio, and we’ve got the inside scoop on how it all went down.

We’ve also have 4 other tasty scoops for ya to help with managing configuration of clusters, saving money and improving reliability with cloud providers, implementing special load balancing with gRPC, and making CI/CD happen with Amazon EKS and Jenkins X!🍦

Well of course we had to mention this weeks HUGE acquisition. We don’t even need to say which one we’re talking about because we know that you know what we know 😉. Meanwhile, CFF was also making moves to get a little closer to CNCF. Oh, and while you’re here check out the new tools we found to help you step up your K8s game. (Spoiler alert. They include AWS Spot Instances & Gravity Cluster Cloning) 😯.

This week we'll enjoy a nice info-rimmed K8s cocktail made up of 1 oz of popular news, 2 oz of K8s-advice, and 1 oz of dev-support 🍹. It packs a punch, including dashes of why Google is adding efforts into making Spinnaker a better cloud deployment tool, why you should use Helm to manage K8s charts, and why Apache Kafka is great for fault tolerant storage. Cheers! 🎉

If nothing else, the kubernetes community is a content MACHINE 🤖. There is always something new to learn, and that’s why we go out and find neat things for you (and provide erudite summaries 😛). One of the best things about Kubernetes is that things are often also built on Kubernetes in order to use Kubernetes. Dig In!

Kubernetes has a lot of options, so many that you couldn’t possibly include them all in your own cluster without turning it into Mr. Potato Head. In this issue we look at a few lists of neat Kubernetes tools as well as best practices when it comes to implementing them, so you can keep your cluster’s ears on straight.

This issue we have a mix of tools and best practices that will keep you fueled up for the week. You might notice along the way that the kubelist editors finished writing this week's issue right before sitting down to eat.

This week the team at CNCF have been busy making improvements to our favorite container orchestrator. Below you'll find what you can expect from the updates, as well as some helpful tutorials for those who are struggling to implement a k8s admission webhook, or those who need a better tool for managing disaster recovery. Happy learning!

The perks of distributed systems come at a price — more complicated debugging and managing processes. That's why this week we’ve gathered a few tools for you to help track your k8s problems, find solutions, manage your microservices or clusters, and build merrily!

New to Docker or Kubernetes and finding yourself lost in the key concepts like containers, images, pods, and more? If this is you, we have a special set of intro's that'll give you a better understanding of k8s and how each part is made.

Already a k8s pro but a k8s code n00b? Keep an eye out for 'A tour into k8s's code'. Know plenty of kube, but confused when it comes to schedulers? Then be sure to read 'how kubernetes is transforming into a universal scheduler'.

Improve your Kubernetes self by digging into these great articles on controllers, workflow, affinities, aribtrate 😲, and a Magic Sandbox.

Welcome again to a super special entirely new but still the same issue of Kubelist! This week, our Editor-in-Chief went on shore to speak at Gophercon. But rest assured, our skippers didn't skip Kubelist day.

Welcome to a very special almost entirely new release announcements issue of kubelist! This week, we've got a handful of updates and new projects. For those of you that don't enjoy NEW PRODUCT BULLETINS we've also included a guide for installing kubernetes on bare metal and CentOS, and a way to use Helm without actually using Helm. Enjoy!

Welcome to a truely special issue 27 of kubelist! This week, we get meaty with networking, pentest our own cluster, and try and understand why this blockchain thing needs servers. Plus, we peek behind the curtain, and reveal a bit more about the kubelist mythos.

This issue is very special, like all the others. This week we learn the dark and terrible secret hiding within every Target store (it's stateful applications!). If you look closely within one of the other posts, you'll find details of a similar setup for Chick-fil-A, too! It's a treasure hunt for your mind and eyeballs!

Welcome to a very special RBAC double-shot edition of kubelist. In addition to RBAC, we've got bare metal networking, for those of you that avoid the cloud (or build your own!), and end to the vicious Kubernetes vs Docker debate (?), and cake! Yes, cake. Well, StatusCake; you can't eat it 😢.

Welcome to a very special not entirely Google news issue of kubelist! This week, the kubelist editors worked very hard to include information that didn't come from Google Cloud Next '18. We think we did pretty good! While you enjoy this batch of links, we'll be patting ourselves on the back.

Welcome to a special security issue of kubelist. This week's issue is loaded with good security information for your control plane, your workloads, your applications, your mind, your body, and your soul. Most importantly, and very rare for our industry, is that there's zero fear mongering or scare tactics! So read up, learn, and feel good.

Welcome to a very special post-apocalyptic theme park issue of kubelist! This week, we've got high octane tweets, high rev tooling, a theme park, and a migration story with more rises and drops than the roller coaster you rode at this year's KubeCon EU party! Please keep your hands and feet inside the newsletter at all times.

Welcome to an extra special birth of a nation issue of kubelist. This week, we celebrate American Independence Day, and Canada Day. And what better way to celebrate these holidays (besides with fireworks) than Kuberentes news? This week's news ends our streak of managed Kubernetes releases; collect the winnings from any bets you placed.

Welcome to a very special multiple versioned issue of kubelist! No, we're not A/B testing the content; we're just unreasonably excited about multiple version support for custom resource definitions in Kubernetes 1.11. A new release of Kubernetes isn't the only release this week, as we see another entrant into the managed Kubernetes game. Will we continue our now 3 issue strong streak of managed Kubernetes announcements next week? Time will tell!

Welcome to a very special first day of summer binge watching edition of kubelist!

At kubelist, we know there's no better way to beat the heat and long days that come along with summer than snuggling up indoors under a blanket and binge watching a full show. Close those blinds, crawl under your quilt made of old conference t-shirts, and enjoy this week's content!

Welcome to a very special follow-up happy birthday edition of kubelist! This week, AKS celebrates its 0th GA birthday, we look at some visualizations that would be perfect for the command station of your space cruiser, and we return to an old favorite: fear mongering about crypto hackers!

Welcome to a super special birthday edition of kubelist!

This week, we're celebrating two birthdays: The 4th birthday of Kubernetes, and the 0th birthday of Amazon's Elastic Container Service. To celebrate, kubelist is serving you up delicious virtual slices of pound cake with real buttercream frosting, topped with link sprinkles (linkles)! Enjoy!

Welcome to a very special expanding brain edition of kubelist! This week, we're bringing you a collection of thought pieces across the full spectrum. Did Kubernetes win already? Is it too complex to win? Or maybe it doesn't matter, and you just want to get these gosh darn logs aggregated?

Welcome to a very special spring fashion edition of kubelist! This week, we've got all the hottest trends, from ad-hoc code execution to accessorizing with persistent storage. Your clusters are sure to look their best this season!

Kubernetes is exciting, there is a lot going on in the community and a lot of components to why it rocks: CRDs, sweet networking, isolation, and more more more. Join us this week to look at why folks might think it's complicated and how we might embrace that complexity and get on with our kubelife.

Welcome to the spooky 13th issue of kubelist! The kubelist editorial team is still getting over their jet lag after returning from Copenhagen, so they are taking it easy this week, and presenting you with a selection of their favorite talks from KubeCon / CloudNativeCon EU.

We hope you find these videos as enjoyable as smørrebrød and dild akvavit.

Hello! This is the Stateful edition of Kubelist. So called because the resources below can help you get started on your stateful journey or help you expand your mind on how you might think about incorporating state into your Kubernetes app (AWS service broker! gVisor! Digital Ocean primitives!) .

Bonus: Obsessed with hot reloading all the codes? Check out ways to incorporate that into your dev workflow in a Kubernetes blog post below. 🎉

Welcome to a very special week before KubeCon EU edition of kubelist! The kubelist editors are very excited to see what new announcements come out of KubeCon, and to hear about what has the community frustrated and excited.

But KubeCon is next week! This week, we've still got a boatload of news and information for you. On to the content!

Welcome to the operating Kubernetes edition of kubelist. If you thought operating the Kube was fun wait till you read up on these operator goodies.

From security, networking, logging and back again, operating the 🗹 is an adventure with several side quests and minigames. Get ready for several deep dives on what it means to operate the 🗹 and level up your 🗹ness. ⚔️

Welcome to a very special nothing-has-changed edition of kubelist! This week, the kubelist editors continue to get comfortable with their new logo, snuggling into it like that old sweater you save for weekends around the house.

Get comfy with us, and enjoy reading this week's selection of new Kubernetes content. 🛋📚

Welcome to a very special makeover edition of kubelist! This week, we've got our own brand-new logo! We probably won't change it again next week. Probably.

This week's edition of kubelist highlights how Kubernetes will play its part in ushering in a dark future where robots rule the world. Enjoy! ❤️

Welcome to a very special makeover edition of kubelist! This week, we've got our own brand-new logo! Yes, we're aware of how many spokes it has :)

Kubernetes itself got a makeover this week as well, with the release of Kubernetes 1.10. Congrats to everyone involved! 🎉

Welcome to the sixth issue of kubelist! This week we've got a virtual loot crate of links: new project announcements, some meaty blog posts, and another reminder that you need to stop sarcastically posting about "M$" on slashdot. kubelist — it's like NatureBox for your mind!

Welcome to issue #5 of kubelist! This week, we've got comparisons, conflict, countdowns, and code.

While you enjoy browsing this newsletter, the kubelist editors will be figuring out how they can sneak a reference to Darude's Sandstorm into the next issue.

Welcome to issue #4 of kubelist! The automation procrastination continues from last week over here in the kubelist editor's bullpen. Instead,we cleaned up the website mobile rendering, then googled "signs of procrastination" to see if distracting yourself with other tasks was one.

On to the links!

It's the third issue of kubelist! Last week we planned on automating some of the process of running kubelist. Automation is a key facet of computing. So is procrastination. We chose the latter.

This issue covers everything from business deals to kernel system calls. At kubelist, we like a balanced diet of links.

Welcome to the second issue of kubelist! Next week, for the third time, we'll have to start automating more of the process.

This week we're bringing you some heavy reading, with ebook collections and papers, in addition to our regular news. Grab yourself a warm drink, cozy up, and enjoy!

There’s a lot of news, tutorials, opinions and new projects around Kubernetes that comes out every day.

It can be hard to keep up with! We’re going to hunt through the new content weekly, and send you a curated list of the best links, with commentary to boot!

— Your pals, the kubelist editors.
