CUE Configuration Kernel (Part 1/2)

Mon, 27 Jul 2026 14:23:12 +0200

Subtitle: Mastering Declarative Configuration Options

If you’ve spent any time operating Kubernetes in production, you’ve hit the Wall of YAML. Helm charts nested inside other Helm charts, Kustomize overlays overriding overlays, and a sea of copy-pasted boilerplate that slowly drifts across dev, staging, and production environments.

Most platform engineering teams try to solve this with more template processing, leading to the infamous "Kubernetes configuration tax" where engineers spend more time writing string-replacement logic than writing core application code.

Why APe?

APe je náš rodinný maskot a průvodce na cestách pětičlenné rodiny (Adriana, Petr, Mikuláš, Štěpán a Rozárka) z Brandýsa nad Labem - Staré Boleslavi. Volný čas nejraději naplňujeme společným sportem, rodinnými expedicemi, dobrým jídlem a kávou. V roce 2009 jsme procestovali Nový Zéland, Austrálii, Samou a Cookovy ostrovy a spíše než chlebem a solí Vás doma uvítáme sklenkou dobrého vína.

Naším nejnovějším rodinným dobrodružstvím je Stezka Českem — v roce 2026 máme úspěšně v nohách etapy ET15 a ET16 (Novohradské hory), což znamenalo parádní túru dlouhou kolem 200 km.

CLI-first Password Manager: Gopass

Tue, 10 Feb 2026 14:00:00 +0000

gopass is a modern, interactive UNIX password manager wrapper designed for secure, multi-store (e.g., combining independent stores like personal and acme for work), and Git-native secret operations. This guide covers setting up gopass from foundation to team-mount configuration utilizing age encryption.

[!TIP] Since gopass is fully backward-compatible with the standard pass directory structure and commands, you can also review my core UNIX Password Manager (pass) Cheat Sheet for standard references.

Migrating to Fish Shell

Sat, 20 Sep 2025 11:00:00 +0000

In 2025, after 15 years of utilizing Zsh, I finally made the switch to Fish Shell . It has quickly proven itself to be an incredibly fast, highly interactive, and absolute favorite everyday terminal companion.

All of my custom configurations, abbreviations, prompt settings, and custom functions can be found inside my dotfiles repository:

Image builds with DockerMake

Tue, 06 Mar 2018 15:01:07 +0200

Dockerfile is nice, but it’s a puppet toy when it comes to scale. I am looking for a solution to consistently build many docker images with shared layers and consistent and predictable build workflow.

TL;DR 🔗︎

My use-case is simple. I want to build matrix of docker images for kitchen-salt CI, containerized Salt-Master and bare-bone OS boilerplates. With Salt, salt formulas installed or without it at all. That makes more than 60 image versions.

Salt-Formulas updates

Fri, 29 Dec 2017 12:01:07 +0200

Sum up all features on salt-formulas project (https://github.com/salt-formulas ). For the first, and only this time, for the whole year.

The most features comes from Mirantis and it’s MCP product portfolio, however the public participation in the past year was also important.

As the I generated it, and as I have done only limited post-processing the content might contain some formatting issues. Further reviews will come “seasonal” and hopefully better formatted.

Salt water to Helm Chart's wheel

Thu, 14 Dec 2017 12:01:07 +0200

Flexible way to perform configuration management actions in the Helm chart’s.

We uses years Salt, Chef, Ansible, … to do complex configuration steps, but when it came to implement a new feature in Helm Chart app folks once again tend to fall back to bash, curl and the Helm hell templates.

My use-case is simple. I want to update Influxdb chart . and provide way to:

Albania 2017

Sun, 22 Oct 2017 01:01:01 +0200

Three mens, one free week, roadtrip in Albania. Tirana, riviera, south and finally the transit Budapest.

TL;DR 🔗︎

We planned the trip one week before we left. Albania is known for its raw nature, mountains, and coast. Visiting mountains in the north part at the mid of the October was not an option as the weather is colder and we wanted to travel light.

We got nice recommendations from "Alfi" an Albanian friend who runs a nice Caffe/Bar in Nymburk. As many people, even we considered Albania and undeveloped country and poor people. What a surprise we soon have found a much better picture of the region.

Salt NACL encryption for external pillars

Tue, 19 Sep 2017 12:01:07 +0200

This article is about encrypting Satl external pillars with NACL.

TL;DR 🔗︎

Salt NACL is based on another SaltStack project libnacl , an wrapper for libsodium and Salt nacl resources (module , runner , renderer and ext_pillar ).

Overview of merged features to develop branch:

NACL module, runner (around 2015.x)
NACL update with secretbox, sealedbox (around 2017/Aug)
NACL render with boxed syntax support NACL[Cr7ptHere=] (around 2017/Aug)

Testing salt formulas and models with kitchen-salt

Thu, 20 Jul 2017 12:01:07 +0200

TL;DR

An overview how to implement salt-formula test's with kitchen-salt.

Overview

In this article I will talk about writing and testing https://github.com/salt-formulas[salt-formulas ]. An curated collection of formulas behind salt-formulas community. The concepts however will fit to any salt formula.

If you are interested in https://github.com/salt-formulas[salt-formulas ] read more at: https://salt-formulas.readthedocs.io/en/latest >[readthedocs salt-formulas].

To test formulas we will use https://github.com/saltstack/kitchen-salt[kitchen-salt ] framework.

Docker Swarm meetup talk

Docker Swarm

I have been working closely with TCP Cloud in my spare time during past weeks to evaluate Docker Swarm cluster orchestration. Kind of easy level to get some insight into the product and it’s bugs ;). Yeah.. it’s not production ready yet!

Anyway I am going to deliver a sweet talk and open discussion at today’s Docker Meetup (Prague). For these who may concern the presentation is online already. (http://slides.com/petrmichalec/docker-swarm )

Started IBM internal LEVEL DEVil workshop series

Mon, 18 Apr 2016 22:39:06 +0200

LEVEL DEVil workshops

Running a DevOps workshop for Poland colleagues in March was a one thing but from a day one I was quite sure I will do have to repeat it locally.

Practicing DevOps and Continuous Delivery in company as IBM and for the enterprise customers might be a tough task. That’s nothing about enterprises, IBM is actually on a global level doing pretty much well in my eyes in the kind of internal transformation. Past are the days of rigid project management. The teams started to be agile, practice devops but a real break through was the “design thinking” initiative and all around “white watter” project. Teams running internal research, development, teams participating open source communities are agile, running complex CI/CD pipelines and using “edge” tools all of the kind. Geeks in IBM are open to OpenSource since early days and nobody should be surprised. IBM was one of the first enterprises that supported OpenSource projects at scale and that business decision was nothing else than that techie people in company liked it very much.

Running devops workshop in Warsaw

Wed, 09 Mar 2016 12:23:39 +0200

DevOps workshop with Chef

At the end of the 2015 I was asked by IBM colleague from Poland who is leading a team of Java developers to develop and deliver a DevOps workshop.

I took a challenge and delivered March 9-10 in Warsaw personally. The slides from the event are available at: http://slides.com/petrmichalec/devops-workshop

Agenda 🔗︎

At first quite challenge as the DevOps topic is so wide, right? Finally I narrowed agenda to some “devops” discussion, Chef.io and Docker including extensive labs.

DevOps Kung-fu workshop

Tue, 26 Jan 2016 13:50:32 +0100

Work in progress…

I am now working on DevOps workshop that would show up Chef, Consul, Docker possibilities in DEV and orchestration together with KitchenCI and InSpec testing and auditing.

As a first stage I created my own version for DevOps kung-fu presentation: http://slides.com/petrmichalec/epcim-devops-cult

DevOpsKungFu presentation

Note: this was originaly presented by Adam Jacob / CTO of Chef / @adamhjk - http://github.com/chef/devops-kungfu . Worth to watch youtube stream BTW.

How i found hugo

Mon, 05 Oct 2015 10:31:07 +0200

As my Django site from 2006 or so went recently south I decided to to make it up from scratch.

Original apealive.net website

Even though I am now pretty solid in DevOps, applying it on low frequency used blog and keeping django running for years it’s overhead. I will rather spend that one with my kids. Sorry loved #django #python ;-(.

On the other hand, during the time, I wrote few pages using static generators and Hugo is the latest one I kept an eye on. So why not give it a chance. Well there is only one summary: Besides @spf13 is supposed to be genius - Hugo is really the framework that makes building the webpages a fun again!

Mon, 14 Nov 2011 08:24:02 +0000

Saturday was last ride this year.

Rychlik p 1831 Jordán odjídí z Praha hl.n. v 8:43. Vlak nečeká na žádné přípoje. Uschova během přepravy rozířená přeprava spoluzavazadel, předevím jízdních kol. Praha-Hostivař 8:56 Čerčany 9:21 Beneov u Prahy 9:31 Střezimíř 10:14

Ve ctvrt na jedenact vyrazime ze zastavky Strezimir a pojedeme po hrebenech nad Prciceme pres Sedlcany na Neveklov, smerem k Sazave a dale ku Praze jak komu libo.

For me personally and honestly for my bike it was last ride ever.

Meeting our flat again

Thu, 10 Feb 2011 17:08:18 +0000

With feelings of "just" longer vacation we are back at home country. Adriana noted that it's cold and a minute later paced a question When this Europe vacation ends?

Just for all our readers. We are in CR since 25.12. Since that time to Feb 06 we have been staying in our flat over night just for one night. Seems we are still live like an backpackers :-D. Sure there was couple of reasons - meeting friends, pub & beer, meeting friends, pub & beer etc. Last two weeks in February we took care of Adriana brother children (4y,8y and 17y) while he was on his Thailand vacation. At the time of writing this post we are even back at our regular jobs, monkeying money again :-).

Vzpominky a Babicky

Sun, 27 Jun 2010 19:43:14 +0000

Vydávám pdf verzi pamětí mojí babičky. Je to rodiná záležitost, ale třeba se najde i někdo jiný kdo se začte.

Sestavené to je tak jak jsem dostal nakázáno podle číslování. Na konci jsou pak různé články a dopisy které publikovala v tisku.

Anki, sentence translation excercises

Sun, 06 Jun 2010 16:27:59 +0000

Summary

I have managed to grab Questions and Answers from scanned PDF version of real grammar book and create an Anki deck from it. Although OCR was not perfect at all I was able to restore 50% of all exercises using some smart reg ex replacements in vim editor. Publishing final deck is not possible because of legal issues but I have decided to publish this how-to.

Update: I have decided to provide copy of the deck to anybody who will prove that is owner of the book. Actually I don't know any other way how you can prove that knowing you personally or sending me a digitally signed document where you declare it and will allow me to publish it. Suggestions welcome.

procabrit mozek II

Tue, 01 Dec 2009 09:22:14 +0000

Je to nějakou dobu co jsem se zaměřil na výběr aplikace co by mi opět pomohl zapomenout zapomínat.

Tenhle post jsem připravil jako návod pro všechny kamarády, kdo budou mít zájem se do toho taky pustit.

Tak před deseti lety jsem si pořídil [1]_ sw Supermemo na učení anglických slovíček. Nutno dodat, že v tomhle oboru mám jen ty nejlepší zkušenosti. Za rok a půl jsem natřískal do hlavy přes 4000 slovíček. To jsem měl hlavu něco jako malý slovník. Mít možnost něco takového používat za doby základního a středoškolského studia by byla naprostá bomba. Dnes po cca šesti letech co už Supermemo nepoužívám si jich pamatuji tak 3000. U toho tisíce si ani nevybavím, že jsem je kdy viděl. I přesto to považuji za naprosto perfektní výsledek

Nelze spustit JavaScript.

Tak jsme upgradovali

Wed, 28 Oct 2009 21:53:02 +0000

Tak jsem právě nahrál novou verzi webu. Lucka s Karlem mne určitě utlučou, že jsem raději neupravoval fotografie z "večerníčkové" akce. Na ty se ovšem taky těším, takže jsou hned v pořadí.

Co je na webu nového. Dokončena stránka tagů, upravena stránka bookmarků, lehce vylepšen vzhed a konečně podpora captcha fieldu u komentářů, takže konec spamům.

Jak odstranit diakritiku z názvu souborů

Tue, 23 Jun 2009 10:44:06 +0000

Potřeboval jsem odstranit diakritiku z názvů souborů. Pod winxp s cygwinem (tr viz dále nefungoval a o příkazu unaccent jsem nevěděl). PS: Filtruji .svn adresáře. S unaccent by to bylo asi výrazně rychlejší. IFS je asi zbytečné. Umí si poradit s duplicitami. Adresáře neřeší.

Výsledek vypadá takto:

 #!/bin/bash

 srcenc=cp1250

 SAVEIFS=$IFS
 IFS=$(echo -en “\n\b”)

 if [ $# -eq 0 ];then
 echo “Usage: $0 directory …”
 else
 while [ $# -gt 0 ];do
 if [ -d “$1” ];then
 find “$1” -mindepth 1 -maxdepth 1 -type f | grep -v “.svn” | while read name;do
 echo “INFO: Filename - $name”
 nname=”$(iconv -f “$srcenc” -t “ascii//TRANSLIT” <<< “$name” )”
 nname=”$(echo “$nname” | sed -e “s/’//g” )”
 if [ “$name” != “$nname” ];then 
 if [ -e “$nname” ];then
 echo “WARNING: Filename already exist - $nname”
 i=0
 oname=”$nname”
 while [ -e “$nname” ];do nname=”$( printf “%s.%05i” “$oname” $i )”;i=$(($i+1));done
 fi
 svn rename “$name” “$nname”
 fi
 done
 find “$1” -mindepth 1 -maxdepth 1 -type d -print0 | xargs -0r “$0” | sed -e “s:[-a-zA-Z0-9_/. \]*.svn ::g”
 shift
 else
 echo “Directory $1 does not exist”
 fi
 done
 fi


 # restore $IFS
 IFS=$SAVEIF

Pročabřit mozek

Fri, 10 Apr 2009 15:44:01 +0000

Znáte to, občas je dobré si nějaká slovíčka zopakovat.

Hledal jsem nějaký pěkný opensource co by mi vynahradil dnes už poněkud zastaralé a v linuxu nepodporované Supermemo . No a našel jsem minimálně dva pěkné kousky. Tak za týden se podělím o zkušenosti, teď mě čeká konverze znalostní databáze supermemo2004 do Q&A formátu co schroustají ty první dva.

Anki - http://ichi2.net/anki/index.html

Pěkný, podporuje mobilní klienty pro iPhone a Android, akorát vyšla nová verze, databáze se dají stahovat a sdílet na internetu, online verze.

Exiftool - pár triků na fotky

Fri, 10 Apr 2009 11:53:44 +0000

Ahoj, dnes prakticky.

Všichni fotíme. Mám v rukávu pár triků pro manipulaci s exif informací uloženou ve fotografii. Při zpracování fotek z Thajska jsem měl záběry z cca pěti fotoaparátů. Někteří autoři měnili čas fotoaparátu během přejezdů čaosových zón, jiní ne. Bylo třeba hromadně opravit čas ve všech fotkách a pokud možno dosáhnout jednotného řazení fotek v adresáři pro příjemné procházení.

Potřeboval jsem tedy co uměl modifikovat v exif informaci fotografie datum a čas vytvoření. Následně pak použít opraveného data a času pro změnu jména fotky do názvu např: YYYYMMDD_<puvodni nazev>.jpg .
