The hiring process for high-tech is completely screwed. Here’s why and how I fixed it for me and my team

22.12.2022 - https://y-b.one/2022/12/the-hiring-process-for-high-tech-is-completely-screwed.-heres-why-and-how-i-fixed-it-for-me-and-my-team/

Many years ago I had to hire a helping hand for myself for a first time. This was a very painfull, almost killing process. And I fixed it for the every next time. This article explains how.

IV: Deploy kafka (RedPanda actually) to our k3d cluster

24.02.2021 - https://y-b.one/2021/02/iv-deploy-kafka-redpanda-actually-to-our-k3d-cluster/

Actual kubernetes-native apps often communicate not directly, but by sending messages to each other. The most common messaging apps for them are RabbitMQ, Redis (despite it’s actually a caching thing) and Kafka. In this case we’ll deploy a lighter Kafka alternative — Red Panda — which is much simpler in deployment, wa-ay less resource-greedy, but fully compatible with the original Kafka protocol.

III: Building kubernetes home lab with k3d — Service mesh and Postgres

02.02.2021 - https://y-b.one/2021/02/iii-building-kubernetes-home-lab-with-k3d-service-mesh-and-postgres/

Writing kubernetes-native apps often requires inter-service communications and the best way to do that is to use the Service Mesh which helps services to discover each other and communicate. Also there could be need a database to store processed data and as an example we’ll deploy a k8s-native Postgres.

II: Building kubernetes home lab with k3d — Monitoring

22.01.2021 - https://y-b.one/2021/01/ii-building-kubernetes-home-lab-with-k3d-monitoring/

The second part of the “Kubernetes home lab with k3d” series. This part is all about monitoring using Grafana-Prometheus-Loki stack

I: Building kubernetes home lab with k3d — Cluster deployment

07.12.2020 - https://y-b.one/2020/12/i-building-kubernetes-home-lab-with-k3d-cluster-deployment/

Kubernetes spread is so wide these days so any programmer/DevOps pretending to be a “modern one” shall have a hands-on experience with it at least at a scale of the home lab. So this topic is exactly about building one.

Seamlessy dump, encrypt and compress your database to the cloud

07.07.2019 - https://y-b.one/2019/07/seamlessy-dump-encrypt-and-compress-your-database-to-the-cloud/

There are a lot of places where using cloud databases isn’t a production solution for various reasons. We’re not going to discuss that, but will backup the Postgres database to the cloud and encrypt it on the fly. There is no difference what type of DB to dump — we will use Postgres just as an example.

There are several common options on how to backup database:

• make a complete database dump to file
• backup database’s transaction log between full dumps

For really large databases the second option could be the only way to not get broke by the storage bills, but for databases less than 30GB in size a daily full dump is the best solution.

After a long-long time passed, finally, this site is going for resurrection. :)

Since the last post I’ve moved from Russia to Israel, learning almost new profession and made my life a lot easier overall.

So, I decided to use that space to copy-paste usefull topics that respond my current interests. So here would appear various things related to DevOps methology and instruments, cycling, motorcycling, aviation and and other things I’d fell in love with.

Provider-less one-time password for linux servers

There are some cases when you have to setup a somewhat hardened security but keep content shared and exclude dependencies form any third parties

Here is starts.

I’ve decided to drop all of my older records, since there is nothing left there neither interesting nor actual.
