Monitoring the boat network with SignalK

22.10.2026 https://y-b.one/2026/10/monitoring-the-boat-network-with-signalk/

A modern boat without internet is a boat without weather, messages and half of its brains. The router sits on top of the mast where you can’t look at its lights, so it needs an eye: a Signal K dashboard that shows what the boat network is doing, and two buttons to kick the internet when it hangs.

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.

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.

Making a dumbest tablet a navigation device with NMEA

22.10.2026 https://y-b.one/2026/10/making-a-dumbest-tablet-a-navigation-device-with-nmea/

Used tablets are cheap and everywhere, and most of them have no GPS at all. A chart app without a position is just a very expensive paper chart. So let’s make the boat’s 5G router tell the tablet where it is, over Wi-Fi, with NMEA and a tiny container.

The hiring process for high-tech is completely screwed. Here’s 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.

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

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/

Cloud databases aren’t always an option, but backups are never optional. A small Bash script that dumps a Postgres database, compresses and encrypts it on the fly and sends it to the cloud, run by cron at the least busy time.

Provider-less one-time password for linux servers

29.07.2018 https://y-b.one/2018/07/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

Installing Mikrotik LAMP R16 on a sailboat

22.10.2026 https://y-b.one/2026/10/installing-mikrotik-lamp-r16-on-a-sailboat/

Marina Wi-Fi is a myth and a phone hotspot dies the moment the phone leaves the boat. So the boat got its own 5G router: MikroTik LAMP 5G R16. This is how to set it up from zero with one script that survives being run over whatever mess is already on the router.

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.

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.
