Kind - or Kubernetes in Docker - is a tool that allows you to easily spin up your local k8s cluster and was originally developed to test Kubernetes itself.

However, you can use it for the local development as well. This article describes some caveats regarding using Kind for such kind of things.

Blog posts about why people chose Nomad over Kubernetes are not that common these days. It makes them even more interesting in my opinion.

Here Karan Sharma describes, how he migrated from Kubernetes to Nomad for his home workloads. He also mentioned that they are planning the same migration at his workplace as well.

I would add just that you have to always strive for a "fit for purpose". And there are definitely a lot of purposes Nomad fits well.

​​Наш наступний гість — Юра Рочняк.

В студентські часи був активним учасником локальних університетських медіа. Написав одну з найвідоміших статей в журналі КПІшник. Працював у Adobe і Preply. Веде один з найбільших ТГ-каналів про DevOps (@catops), створив український осередок Hashicorp User Group і допомагає в організації DevOps Days Kyiv.

Поговоримо про те, чому мати власне девопс-ком'юніті корисно на співбесідах. Як організувати локальну юзер-групу великої корпорації і для чого це потрібно.

A rant about Helm

tl;dr:
Helm violates some principles of the Kubernetes architecture:
- it is partially imperative
- it not necessarily provides a good abstraction, since you frequently need to know what's going on in a chart
- Helm becomes a monolith on its own, while each Kubernetes component aims to do a suingle thing, but do it good.

Also, author promotes Kustomize and controller/operator approach for your Kubernetes application lifestyle management

#kubernetes #helm

HashiCorp announced a general availability of the Terraform Cloud Operator, which allows you abstract the infrastructure as Kubernetes resources.

In order to use it you have to have Terraform Cloud subnoscription, so this is might be not that important news per se. However, this shows that Kubernetes is a platform on its own and people alongside with well-known companies acknowledge that. Also, managing your insfrastructure from within a Kubernetes cluster doesn't seem like a wrong order of operations. Such things like Terraform Cloud Operator only proves that.

BTW, you can write-up your use case for potential Terraform OSS Operator in this issue

Argo Workflows v3.0 is out!

An article provides some history of Argo development as well as new features of the v3.0 release:

- New APIs for Argo Events
- Controller High-Availability
- Key-only artifacts make it easier to perform map-reduce operations
- Moving the repository. Now it's argo-workflows, not just argo, which caused a lot of confusion with ArgoCD
- Go modules support

Статья о том как устроена DynamoDB в амазон. Очень наглядный пример архитектуры БД широкого назначения. https://medium.com/@uditsharma/internals-of-dynamodb-b3b7912256ae

I know that this article is not about DevOps or infrastructure engineering, pipelines, whatsoever.

But I got some genuine satisfaction reading this.

Parse JSON like a Rockstar!

P.S. PC players of GTA online may appreciate this post anyways

Some good practices on how to tag your AWS infrastructure for better cost management and compliance audits.

As someone, who works with AWS on the daily basis, I can say that this article is pretty useful. We are trying to create a similar account structure / tagging in the company I work for as well.

This article sums up ideas regarding proper resources tagging and also AWS account layout, which can help you to organize and track your assets better.

It recommends some third-party tools for cost audits as well.

Basic practices for optimizing read and write performance in PostgreSQL.

A long read about the factors that affect PostgreSQL performance as well as some insights regarding the internals.

An article on how to scale Celery workers in Kubernetes based on RabbitMQ queue depth.

Basically, this is an example of how to use custom metrics for scaling. They were using KEDA to collect those metrics. So, it may also be interesting to those who want to know more about KEDA itself.

"Quick read" by John Arundel called Writing slower Go programs. Actually, this can relate not only to Go.

The idea is that you'd better optimize your code for readability, brevity, and simplicity to understand; rather than speed. Unless, you're working in an industry that requires blazing fast response times or works under shortage of resources. Such as game development, IoT, network equipment and so on. However, if you do work in such an industry, you likely know, what's you're doing.
