Cloud native with Saiyam - November mid edition

Welcome to the November First edition and thank you all for supporting my work. You people are the best.

If you have loved me and my content then you will love this too <3 . I want this to be like me telling you stuff that I found useful and from where I learnt this month. If you have anything to be included, feel free to reach out on Twitter. This is the first edition for November as I feel so much have happened already that you need to know, amazing session, blogs, tools around !!

It was a festive season in India and everywhere you can see the decoration if you go out on the streets. I missed my brother so much as we used to be together for Deepawali. Life is hard and unpredictable, please enjoy each moment and show love to your near dear ones.

Streams

So many streams happened with a HUGE week -> CI/CD week

CI/CD — www.youtube.com

We discussed Projects including -> Tekton, Sigstore, ArgoCD, Keptn and Jenkins.

Next up are some of the other streams that I did covering:

• Kubernetes Networking by James Strong

• Let's learn K3ai - A lightweight tool to get an AI Infrastructure Stack up in minutes not days. It spins up the Kubernetes cluster and deploys the AI tool of your choice.

• Metrics and Traces with TimescaleDB - This was an interesting stream where Vineeth started from scratch and told about traces and then how TimescaleDB helps with that.

• Monokle - A desktop UI to manage k8s manifests.

News and announcements

• Microsoft launched a new serverless offering: Azure Container Apps - Build and deploy modern apps and microservices using serverless containers. Scale to zero, Service discovery, HTTP or other events (queues, streams), Built with open source - Kubernetes, Dapr, KEDA, Envoye.

I read it somewhere where they said that cloud run was not a good approach for the future and they are on similar grounds showcasing the power of serverless. What do you think about this ? Did anyone try it already?

• GKE image streaming - This is very interesting and helps in fast pod startup and faster autoscaling. There is a similar project that I came across as well.

• Knative 1.0 - Knative turn 1.0 which is a big thing! Check out this Knative series on my channel from the creators and the maintainers.

• Spot compute comes to GKE Autopilot with Spot Pods - Cost savings.

• Prometheus Agent - a new operating mode from the prometheus team which enables new workflows such as low-resources environments, edge networks, and IoT

Tools of the month and great repositories

• Go algorithms - Go translations of the Java source code for the algorithms and clients in the textbook Algorithms, by Robert Sedgewick and Kevin Wayne.

• Mizu - A simple-yet-powerful API traffic viewer for Kubernetes enabling you to view all API communication between microservices to help your debug and troubleshoot regressions.

• Benchmark Operator - The intent of this Operator is to deploy common workloads to establish a performance baseline of Kubernetes cluster on your provider.

• Sysbox - Sysbox is an open-source container runtime (aka runc), originally developed by Nestybox.

• Descheduler for Kubernetes - Descheduler, based on its policy, finds pods that can be moved and evicts them.

• Kip - Kip is a Virtual Kubelet provider that allows a Kubernetes cluster to transparently launch pods onto their own cloud instances.

• Writing a "bare metal" operating system for Raspberry Pi 4

• Kubermetrics is an open-source dev tool that provides Kubernetes cluster monitoring as well as data visualization in a simple and easy to understand user interface

• Autotune - Autonomous Performance Tuning for Kubernetes

• Gyype - A vulnerability scanner for container images and filesystems

Free learning resources

• Free splunk training

• Kubernetes basics by Brendand Burns - Old but gold

• CKAD crash course

• What happens when `Kubectl run`

• Load data from CSV, parse it, resample, and generate an interactive map in GO and HTML

• DevOps Roadmap

• Command not found - type the command and get how to install on various OS.

Saiyam Pathak @SaiyamPathak

Put your best Golang learning resources here 👇🏼 Please add what you learned from that resource as well. Books, playlists, repositories anything! It would be great to add target audience as well like for beginners, intermediate, use-case specific etc. #golang

Andrew Howden (in 🐻@🇩🇪) @andrewhowdencom

SO YOU WANNA BE AN SRE! Well, it's a pretty fun job tbh, I can understand that. But maybe you're like "whoah hey what is SRE even". If that sounds like you, good news! I have some resources to share with you. They're not definitive, but I found them useful. /1

Daniele Polencic @danielepolencic

Does Kubernetes rebalance your Pods? If there's a node that has more space, does Kubernetes recompute and balance the workloads? 🤔 Let's see!

Ivan Velichko @iximiuz

What a handy tool! I can already see how it saves a few round trips for folks like me helping troubleshoot networking issues via Slack. `dstp <host>` shows - ping duration - DNS resolution - system DNS settings - TLS certs information - HTTP status code github.com/ycd/dstp
