Hi there, my name is Max. Or Maksim, as you wish.
It’s just a homepage. I’m too lazy to fill it with my personal info. Look at my blog posts though

As I’ve mentioned in my post about Pulumi, I don’t like
helm templateapproach. In my opinion, it’s better to stick with the tool rather that mimic it’s behaviour. In case of helm “sticking with the tool” also means out of the box support for the standard
helmtool, including plugins.
My tool of choice is Helmsman
I like Kubernetes way of declarative workload configuration, but handling cluster state using dozens or hundreds of YAML files is impractical.
Of course, one can just combine them all into a single uber-YAML . But the harsh reality is, despite the fact that Kubernetes by design can and will apply this configuration asynchronously, and eventually cluster state will achieve the desired state, this “eventually” might be equal to infinity.
There are certain cases when order matters, for instance when new CRD definitions are added, and then new objects with that
Another aspect is complexity, which can be encapsulated by tools such as Helm. While Helm is a good solution for the problem of installing third-party apps, it’s not necessary a right choice for your own services, or for lightweight overall cluster configuration.
And one more thing. I enjoy the kubernetes architecture, even (and especially!) the fact that numerous abstractions are needed to “canonically” expose a single container to the rest of the world. But it doesn’t mean that I enjoy to break a DRY principle, and copy-paste-modify same YAMLs over and over.
So… Pulumi to the rescue!
I have an old piece of hardware with Atom D2700 CPU, which according to ARK is capable of running x64 OS. Vendor, however, never released a BIOS with x64 support, and I was unable to find it on an Internet.
Aside this sad fact, that small PC have decent specs, including 4 gigs of RAM, which makes it a good candidate for a single-node ElasticSearch cluster. I have to collect logs from my Kubernetes cluster somewhere, right?
Unfortunately, Elastic dropped an official
i586support long time ago, which totally makes sense from commercial perspective.
Well, thanks to Debian and Java we still can run ElasticSearch on top of 32-bit Linux!
This tutorial is written for ElasticSearch OSS v7.5.1, and might not work for newer versions, as source code might change!
My Kubernetes is up and running, and I’ve decided to expose certain services to the Internet, while keeping other services inside the home network.
