Kubernetes tutorial for beginners | Horizontal Pod Scaling in Kubernetes HPA’s are stable resources in the autoscaling/v1 API group and their job is to scale the number of replicas in a Deployment based on observed CPU metrics. The autoscaling/v2 API allow scaling based on more than just CPU. You define a Deployment that makes use of Pod resource requests – where each container in the Pod requests an amount of CPU. You deploy this to the cluster. You also create an HPA object that targets that Deployment and has a rule that says something like: if any Pod in this Deployment uses more than 60% of its requested CPU, spin up an additional Pod. Once the Deployment and HPA are deployed to the cluster, scaling operations become automatic. One thing worth noting is that HPAs update the .spec.replicas field of the targeted Deployment. While this update is recorded against the Deployment object in the cluster store, it can lead to situations where the copy of the Deployment YAML file in your external version control system gets out of sync with what is currently observed on the cluster.

Helm in 10min

Hello guys, I made a 10-min video 🎥 to explain Helm ⚓️ and its main concepts. The video shows how to package a Spring Boot app 🍃 and how to deploy it into a K8S cluster. Also, how to search for charts in public repositories and to install them locally.
If you have any feedback about the content or the editing process, please let me know 🙂

Interview with Rona Hirsch, DevOps Engineer at Komodor on ValidKube, Female DevOps engineers and women in tech

Link to the interview: https://www.youtube.com/watch?v=bNG5nRXMCFc

I particularly enjoyed the segments about women in tech. I find that Devops is a very male dominated field and it would be fantastic to have more women in the field.

I’ve maliciously broken two Kubernetes clusters and I’ll be jumping on my YouTube channel live tonight to give people the chance to fix them.

20USD Amazon voucher to anyone that comes on the stream and tries to fix one.

200USD voucher if you manage to actually fix one.

Who’s feeling confident?

Entry Level DevOps Question

I am preparing for a couple of entry-level/junior DevOps interviews by watching mock interview and researching typical questions online. However, many of the mock interviews don't specifically say if it is for entry level, mid, or senior.

Can anyone tell me what level position this mock interview is? It seems way to difficult for entry/junior level, or maybe I am just unprepared?

Microservices Research

I am currently conducting research on microservices for an edge application, with the goal of reducing its latency. As a novice in this field, I would like to seek assistance and guidance from the community. If anyone has any expertise or alternative approaches to share, I kindly request you to leave a comment or reach out to me directly. Your contributions would be highly appreciated and will greatly aid in my research thesis. Thank you in advance for your time and help.

Is Tekton alive? Comparing Tekton Pipelines with Argo Workflows, ArgoCD and Jenkins

Is Tekton still alive? I’ve successfully used this tool in an Openshift environment, where it makes all the sense - there is a proper integration with the platform itself, and RedHat puts lots of effort into making a real CI/CD system out of it. But do Tekton Pipelines make sense today without a wrapper like Pipeline as Code and JenkinsX on top? And are there many companies actually using Tekton, compared to Argo and similar tools? I tried to answer all of these questions in this new mkdev video, plus did some experiments again with editing - hope it’s now even more fun and engaging to watch it, but feel free to roast me in the comments.

BunkerWeb - The open-source and next-gen Web Application Firewall (WAF)

BunkerWeb is a next-generation and open-source Web Application Firewall (WAF).

Being a full-featured web server (based on [NGINX](https://nginx.org/) under the hood), it will protect your web services to make them "secure by default". BunkerWeb integrates seamlessly into your existing environments ([Linux](https://docs.bunkerweb.io/1.5.9/integrations/?utm_campaign=self&utm_source=github#linux), [Docker](https://docs.bunkerweb.io/1.5.9/integrations/?utm_campaign=self&utm_source=github#docker), [Swarm](https://docs.bunkerweb.io/1.5.9/integrations/?utm_campaign=self&utm_source=github#swarm), [Kubernetes](https://docs.bunkerweb.io/1.5.9/integrations/?utm_campaign=self&utm_source=github#kubernetes), …) and is fully configurable (don't panic, there is an [awesome web UI](https://docs.bunkerweb.io/1.5.9/web-ui/?utm_campaign=self&utm_source=github) if you don't like the CLI) to meet your own use-cases . In other words, cybersecurity is no more a hassle.

BunkerWeb contains primary [security features](https://docs.bunkerweb.io/1.5.9/security-tuning/?utm_campaign=self&utm_source=github) as part of the core but can be easily extended with additional ones thanks to a [plugin system](https://docs.bunkerweb.io/1.5.9/plugins/?utm_campaign=self&utm_source=github).
