Ubuntu: Installing NGINX with TLS Certificate from Let’s Encrypt and AWS Route 53
0 (0)

17 August 2026

We have an Ubuntu server running one of our services. The service itself is still at the Proof of Concept stage, so we’re not moving it to Kubernetes yet – but sending traffic in plain text, especially when these are requests to AI Agents with prompts and responses, is not a great idea. So, the… Read More: Ubuntu: Installing NGINX with TLS Certificate from Let’s Encrypt and… »

MongoDB: run in Kubernetes with MongoDB Operator and MongoDBCommunity CRD

24 July 2026

Following up on the previous post Valkey: running in Kubernetes – Helm, monitoring, ACL – we set up Valkey/Redis there, now it’s time to add MongoDB. This is for our new service, which is still in the experimental/PoC phase, but will most likely go to production, so the setup is a bit “under-production” – we’re… Read More: MongoDB: run in Kubernetes with MongoDB Operator and MongoDBCommunity CRD0… »

Valkey: Deployment in Kubernetes – Helm, Monitoring, ACL
0 (0)

22 July 2026

We’re launching a new service for the project, and this service needs Redis and MongoDB. The “technical task” itself looks roughly like this: Redis: task queue + some other stuff (e.g. we stream the agent response from LLM to Redis, and if the user is connected on a websocket – then we stream data from… Read More: Valkey: Deployment in Kubernetes – Helm, Monitoring, ACL0 (0) »

LiteLLM: AI Gateway on Kubernetes and Metrics in VictoriaMetrics
0 (0)

26 June 2026

In the first part – LiteLLM: AI Gateway for LLMs – features overview we got familiar with what LiteLLM can do in general – now we can run it in Kubernetes and connect clients. At the same time we’ll check the integration with our existing monitoring stack – for now just metrics to VictoriaMetrics. Logs… Read More: LiteLLM: AI Gateway on Kubernetes and Metrics in VictoriaMetrics0 (0) »

Arch Linux: a DNS Mystery – VPN, systemd-resolved, and Unbound
0 (0)

21 May 2026

I’d been wrestling with the problem of accessing AWS EKS from the office for a long time – finally lost my patience and figured it out 🙂 Here’s the problem: there’s an AWS EKS cluster with both Public and Private endpoints for the API. Working from my office laptop, sometimes requests to it go through… Read More: Arch Linux: a DNS Mystery – VPN, systemd-resolved, and Unbound0… »

VictoriaTraces: Tracing, Observability, and OpenTelemetry
0 (0)

19 May 2026

On the project, we’ve gradually grown to the point where it’s time to have proper tracing – to build real observability, not just monitoring. A long time ago I did something similar with Jaeger – a monster, and it kind of stayed in my drafts from 2019 or 2020. Since right now our entire stack… Read More: VictoriaTraces: Tracing, Observability, and OpenTelemetry0 (0) »

OpenTelemetry: OTel Collectors in Kubernetes and VictoriaMetrics Stack integration
0 (0)

16 May 2026

Today let’s talk about how to run OpenTelemetry in Kubernetes and integrate it with the VictoriaMetrics stack – VictoriaMetrics for metrics, VictoriaLogs for logs, and VictoriaTraces for traces. Actually, this post wasn’t planned at all, and once a draft did appear – it was supposed to be the third in the series, but in the… Read More: OpenTelemetry: OTel Collectors in Kubernetes and VictoriaMetrics Stack integration0 (0) »

FreeBSD: Jails Networking and Container Management with Bastille

4 May 2026

Sometimes on FreeBSD you need to run services that aren’t officially supported by FreeBSD, and this post actually came about because I was installing Open WebUI on my NAS – and Open WebUI was easier to set up on Linux. So I spun it up in a FreeBSD Linux jail, and to create the container… Read More: FreeBSD: Jails Networking and Container Management with Bastille0 (0) »

Hermes Agent: Running an AI Agent in a FreeBSD Jail with Bastille

3 May 2026

I’ll write about Hermes Agent itself and what it can do separately – today it’s about how to run it on FreeBSD. Yesterday I played around with it on my Arch Linux – now I want a more production setup. I’ll be running it on my NAS with FreeBSD, and obviously only inside a FreeBSD… Read More: Hermes Agent: Running an AI Agent in a FreeBSD Jail… »

Claude Code: creating Kubernetes debugging AI Agent for VictoriaMetrics
5 (2)

30 April 2026

While I’m working on a series of posts about setting up and using Claude Code, here’s a quick example of building my own AI Agent for VictoriaMetrics and Kubernetes, “wrapping” it into a Claude Code Plugin, and creating my own Claude Code Marketplace where similar plugins for developers on my project will live. The general… Read More: Claude Code: creating Kubernetes debugging AI Agent for VictoriaMetrics5 (2) »
