MongoDB: run in Kubernetes with MongoDB Operator and MongoDBCommunity CRD
0 (0)

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
0 (0)

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
0 (0)

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

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) »

AWS: Setting up Okta SSO with AWS IAM Identity Center

31 March 2026

In the previous part of the Okta series we set up SSO for Grafana (see Okta: configuring Grafana SSO with OIDC and Role mapping) – now for a more interesting task: configuring SSO for AWS, with not just login but also user provisioning. Okta has a ready-made AWS IAM Identity Center App that lets you… Read More: AWS: Setting up Okta SSO with AWS IAM Identity Center0… »
