How to upgrade k3s with existing config file

How to upgrade k3s with existing config file

A few years ago I switched from microk8s to k3s on my server. I described the setup process here: Switch from microk8s to k3s. Since then I had to upgrade k3s a few times and I always do not rember how I did it last time. So I thought it might be a good idea to write down the steps I did to upgrade k3s with an existing config file.

Switch microk8s to k3s

Switch microk8s to k3s

I recently switched my HP Proliant Microserver from mircok8s to k3s.

Why did I do it

First of all I’m always interested into new stuff and somehow I found k3s mentioned on twitter and it sounded quite interesting. Second the performance of microk8s on my server was not that good e.g. sometimes when trying to access logs I got timeouts. So when I read about k3s and that it is designed to even run on Raspberries etc. that sounded like a good choice.

Mocking and mock data generation

Mon, 04 Apr 2022 21:47:11 +0200

Mocking and test data generation

For mocking I like to use mockery with testify/mock. Generally the syntax is quite clear:

Example

mock.EXPECT().GetRunnerDetails(1).Return(nil, &gitlab.Response{}, errors.New("Something went wrong")).Once()

The most problems occur when it comes to multiple calls with different data. I was always search I to improve that without blowing up the testing code and making it unreadable. With one of my projects(clinar) I now use data generation functions like the following:

Setup and teardown unittests in golang


Right now we had a lot of discussions about golang in our team. My colleague Andreas complained about the unit testing especially setting them up and using teardown functions. I didn’t add and problem with it until now, but he activated my mind and I searched for sultions for it. While searching I found setup-and-teardown-unit-test-in-go which brought me up to slidely different solution. Basically this is now what I found:



Speed up trivyops using Go routines
Sat, 26 Feb 2022 11:41:11 +0100

Speed up trivyops using Go routines


As I have a project on GitHub (trivyops) which is able to scan multiple (depending on your work 100rds of) GitLab projects for pipelines with trivy results. I thought about how I could speed trivyops up to do it’s job faster and also I was searching for a example were I could try out Go routines and channels.


After playing around a bit with some tutorial projects like multiplying some numbers using Go routines and channels. I pretty fast came up that channels can to more then just transporting simple numbers and that they can also be used with structs. Based on that I refactored trivyops to basically use Go routines to do the API Calls (multiple one in parallel) and retrieve the results via channels. Doing that I was able to reduce the runtime of trivyops for my projects (at about 100 projects to be scanned) from 1.40 minutes to at about 9s :).

I've updated the plugin I use to generate the site. It now dosesn't require a extra yaml file to define the blog posts. The Asciidoc files just need to define the :post-date: Asciidoc attribute and the plugin will just do the ordering and creation of paging links.

MacBook running with Ubuntu 18.04.3 LTS


Last weekend I spend some time to install Ubuntu 18.04.3 LTS on my Mid 2019 MacBook Pro. Unfortunately I already tested it with a USB live version and found out that everything seemed to work except wirless lan. So I just added a few more investigations to find out if it would be possible to get it working. What did I do:
. I checked in about this mac which wlan Module is used and searched via google if there is a driver.
. I found out that there is a driver and just tried it via USB live version of Ubuntu what directly worked.

Updated website


I’ve just updated the website. Basically I just did a little bit theme styling / refactoring and I’ve added some data privacy notes as today the EU General Data Protection Regulation (GDPR) have gone into effect. I think as a private person this doesn’t affect me to much here. But just for the case. Anyway this website is basically text, so I don’t collect any data if you visit side. That beeing saied… Have a nice weekend!



From wordpress to maven-site
Wed, 23 May 2018 08:47:11 +0100

From wordpress to maven-site


The last weeks I worked on swtiching my website away from wordpress and now it’s finally there. Basically I use know the maven site plugin to generate the site out of asciidoc files. To be able to do this I’ve created a small plugin which is able to read a YML definition which includes all blog posts and create some asciidoc with it which is then later generated to HTML via maven site plugin. More details to come soon (maybe) ;)



How-to create your own Certificate Authority
Thu, 21 Dec 2017 08:47:11 +0100

How-to create your own Certificate Authority (or the better way to get working snake oil certificates for internal use).


As I have a local owncloud installation I was searching how to create certificates which work well in Iron, Thunderbird and the owncloud client. Therefore basically I used: the how to which I found on https://niklas-rother.de/artikel/die-eigene-certificate-authority-ca/.


When I was finished I found out that Iron was still complaining about the certificate. The issue was the missing SubjectAltName in the certificate. Therefore I searched and I found the following how to explaining how to add it http://apetec.com/support/GenerateSAN-CSR.htm.

[Unsolved] Trying to create a akka-http server consuming multi-part messages

I’m currently working on a akka-http server which should consume multi-part messages and send back on of those parts to the client. Currently I struggle a bit with the framework itself and especially lambdas as they’re pretty new to me. Here is my current code:

Photoshop CC Keyboard Shortcuts

Photoshop CC Keyboard Shortcuts


I was just searching for a list of all keyboard shortcuts in Photoshop CC. I found a few links which where either to old or I was not able to print them in a nice way in chrome/iron. So I searched further and found something pretty nice:


In Photoshop CC itself you could just go to the edit/bearbeiten menu and there is an entry called shortcuts/Tastaturbefehle (Alt+Umschalt+STRG+k). From there you can export all currently defined shortcuts into a .htm file.



Curves Presets for Lightroom
Sat, 31 Dec 2016 08:47:11 +0100

Curves Presets for Lightroom


Today I created a few curves presets to be used in lightroom:
Curves.zip


To use them you just need to unzip the file into C:\Users&lt;YOUR USERNAME> \AppData\Roaming\Adobe\CameraRaw\Curves and restart Lightroom.


Most of them can be used to give your pictures a special toning:
The first 8 are S curves (or inverted S curves) based on the color chanels. The naming pattern means that the color in upper case letters is boosted in the highlights and reduced in the shadows. Here are some samples:



Groovy, XML and Namespaces
Sat, 10 Dec 2016 08:47:11 +0100

Groovy, XML and Namespaces


I just had to work with Groovy (creating a Pipeline in Jenkins V2) where we needed to handle XML documents. In fact we were reading the documents from disk but just to keep that little example easy I skip this and just create a text variable which includes the XML fracment. What I want to show is how to use the XMLParser together with a XML document which uses namespaces. The sample I’m using is from http://groovy-lang.org/processing-xml.html. I’ve just added some namespaces. Just node the difference regarding the namespace definitions in line 9 + 10 and take a look on the different style of the GPath statements in line 15.



What I really don't like @ Adobe Lightroom

What I really don’t like @ Adobe Lightroom


When managing my photos I’m using Adobe Lightroom since three years now. To publish my pictures on 500px I’ve one publishing service where all pictures are added when I mark them with a color label. That works pretty nice. But what I don’t like is that I wanted to export the pictures in a ordered way and that doesn’t seem to work.



JMS vs. Kafka
Tue, 19 Jul 2016 08:47:11 +0100

JMS vs. Kafka


Last weekend I create a small Java comparison test (yes it was a bit unfair) between Apache Kafka, Oracle Weblogic and WS02 MessageBroker. What I basically did was to create simple clients for all three products (basically a Kafka client and JMS client which was used for Oracle and WS02) and I installed all products with basic configuration (as they can be downloaded). Ok for Weblogic I extended the heap to 2048Mb and used a G1 GC as it was configured with the lowest amount when shipped out. The testclient was pretty simple basically a thread which send always the same message (String “Hello World” attached with an incremented number) to the messaging product. This thread always run 60s and then stopped the test. As expected Apache Kafka ruled the others with a bit more then 75 Mio messages send and stored in a minute. WS02 scored second with at about 1 Mio messages and Oracle Weblogic at the end with a bit more then 100k messages. That was really interesting to see. Especially the huge difference between those two JMS implementations. Would be quite interesting why this difference is that huge. I may check the different default configurations and try to align them. Maybe I’ll also extend the test and run it on clusters of the products…



OSB threading and local proxies

OSB threading and local proxies


The last days I investigated a lot into the osb 11G (Oracle ESB) threading model during my work. I found a few quite nice articles about that topic but sadly they’re mostly not really covering these topic together with local proxies (proxy with transport local or at least http proxies which are hosted on the same nodes). If you’re not familar with threading in OSB I recomment to read those articles first because I base my assumptions and thoughts on those. My main sources are:

Got Android 2.3.7 on my X10 mini

Got Android 2.3.7 on my X10 mini


Hey finally I got Android 2.3.7 working on my Sony Ericsson X10 mini. Which is currently not official supportet and I guess it will never be supported by Sony Ericsson. So I used a custom rom build by CyanogenMod (http://www.cyanogenmod.com). It was not such easy because there was no 1:1 howto and I had to search multiple howto’s (programs and kernels as well) for each step. In the meantime I fleshed with a wrong kernel what leads to system freeze during bootup and was much trouble to flash it back, because it didn’t let me into flash mode. So this post is also not a all in one howto but it lists all needed steps with corresponding links to the howto’s for the details and hopefully it will help others to got it working easier then for me.

hat 600W an 4 Ohm, zwei schaltbare 8" und ein regelbare Horn und ist seit gestern die neue Box unter meinem Ampeg AP-3550 und SVT-IIP. Aber von

vorne… nach ca. 4 Monaten Diskussionen mit Hans (Hans Struck = Eigentümer von FMC), viel lesen zu FMC Boxen auf bassic.ch und schluss endlich reiner Wartezeit aufgrund der Terminplanung von Hans war es gestern endlich so weit und ich konnte nach Ingolstadt fahren und meine Box in Empfang nehmen. Kleiner Tip am Rande: Wenn ihr die Möglichkeit habt fahrt auf jeden Fall persönlich in Ingolstadt vorbei. Wieso? Naja Hans ist super nett und erklärt euch alles rund um die Boxen - aus erster Hand - führt sie selber vor und gibt ansonsten noch jede Menge persönliche Erfahrungen und Tips zu den eigenen Boxen.

Schweinegrippe
Mon, 16 Nov 2009 08:47:11 +0100

Schweinegrippe


… werden die ganzen Schweine eigentlich auch geimpft? Sonst frag ich mich nur wie die Impfaktion überhaupt die "Pandemie" eindämmen soll… meiner Meinung nach die unsinnigste Aktion überhaupt :)


Gut auch, dass von der WHO extra die Pandemie Definition geändert wurde, was unter anderem aus diesem Interview hervorgeht:


Spiegel online


Wie dem auch sei: Meiner Meinung nach die best organisierteste PR-Aktion überhaupt… und das bittere alle machen mit.


P.s. meines Wissens nach ist die Schweinegrippe bisher nur von Mensch zu Mensch übertragen worden aber die Idee die Schweine mit zu impfen fand ich irgendwie witzig.

Currently working as a Service Designer…


… for at last nearly a year now I am working in (I think) one of the biggest SOA projects in Germany. My task ist to design services. So for now I don’t have to code them. The main goal of this services is to make all services busines object modell (BOM) alligned and to provide process automation. For the design we use UML activity diagrams and we write a service-documentation in MS word which describe how to use this services…

MS-Project under Linux
Wed, 17 Sep 2008 08:47:11 +0100

MS-Project under Linux


For those who need to work with MS-Projectfiles under Linux I’ve found something interesting. There is a program called OpenProject which enables you to open and view MS-Projectfiles. In another blog I found some informations, that it does not include all features offered by MS-Project but for my requirements it was good enough. So I think this could be a good alternativ to the commercial ones.

Recommendations to read (Part 1)


First of all there is the new book from my mum. Its called 'Raubkind' and written in german. Here is the description of this book (currently only in german):




Die Fantasie des Protagonisten Jakob schafft Handlungen, vernetzt Beziehungen oder lässt sie bröckeln, bindet oder entbindet Schicksale. "Raubkind" ist das Puzzle-Buch dieses seelenfrustrierten Beobachters, der sich in den virtuellen Lebensgeschichten der Anderen impliziert, um sich jedes Mal neu zu erfahren und korrigieren; die Geschichte eines meist sukzessiv (hinein)gleitenden Ichs mit mehreren Stimmen, Namen und Biografien, knappe Anatomie menschlicher/gesellschaftlicher Unvollkommenheit. Der mit dem Debütpreis des Ludwigsburger Pop-Verlags für 2008 ausgezeichnete Erstlingsroman der Lyrikerin und Prosaautorin Barbara-Marie Mund ist ein Szenario existentieller Sehnsucht nach dem verlorenen Etwas, in einem stetigen Wechselspiel von abgründiger Wirklichkeit und Projektion, von Schatten, Irrlichtern und Irrkreisen.

Working with Smooks

Working with Smooks


Currently I’am workin in a project in Dresden. My part is placed in the ETL (Extract Transform Load) process and I have to do the transform part. So we have to transform XML and CSV files. Some of this files are about 200 Mbyte and we have decided to use Smooks ([HIER DER LINK]). Smooks is a framework to analyse or transform data (not only XML).
To handle a transformation with Smooks you have to create a configuration file in XML. On the project side you can find lots of basic examples which are very useful to get started. What I missed where some more complex mapping examples for the XML-to-Java conversion. So I’ve desided to create one. Basic mapping of XML is not very hard. But my problem was that I had to map elements with the same name which are placed under subelements. Here is an sample XML file:



ServiceMix :: FTP Component
Tue, 09 Sep 2008 08:47:11 +0100

ServiceMix :: FTP Component


So in the project I talked from in the post before we maybe want to use ServiceMix as something like an transfer/routing server. So I looked at the ftp component to be able to get data from servers which are not running on the same machine (now at todays point it seems like that the other servers will bring us the data, so we don’t need ftp, but earlier this was not clear). So the basic configuration of an ftp component is easily done and you find enough documentation to get started. But I want to try the filter property which must be of the type "java.io.FileFilter" so this means we have to create/use an class which implements the FileFilter interface. But how can we add the class to our configuration and how we get maven to compile this class during packaging our component? Here is my solution its something like combining the ftp component with the bean component:

Installing Latex on Gentoo (with bibtex and nomencl)


I installed a second time my Gentoo system with Latex. I need bibtex and nomencl for my diploma thesis, so I have to install an extra package.




Insert tetex USE-FLAG into make.conf


emerge texlive


emerge texlive-latexextra




The last step is needed for extra packages like nomencl…





Impressions from India

Impressions from India


First time as we arrive in Kalkutta, my first thougth was: “what a huge sauna”, temperature at 28° and a humidity at ca. 80%. Now we had to wait for 7 or 8 hours for our domestic flight to Bhubaneshwar. The time we spend with talking and trinking tea… as we arrived in Bhubaneshwar one guy from the university tooks us up. From airport we drove to the hotel to fresh us up and change clothes. After that we drove to university to met the vice chancellor and some other professors. This takes about an hour or something like that. After that we met the students of the exchange program and started the Java courses. At lunch we was at the dining house of the university. What was not much more, then an dump, what is much different from so called “mensa” on german universities. In the evening we fall early in our bets because of the jet-lag.

Endorsement:: Gentto Linux on my AMD 64 X2 4200+ Worksation


Last weekend I’ve found some time to build a linux system for my home workstation (until then I only used a Win XP Installation). After my first tries to reinstall the system with a ubuntu (7.10) installation a view months earlier (a year before there was a Debian/unstable version running on it). I now decided to use a distribution which is not so much “mainstream”. So first I played around with Open Solaris from Sun but sadly, in my opinion, it is an to early release and there are much things I like to use on my Linux desktop which are not supported in the current release. So finally my decision was to use Gentoo. I had planned to use it some years ago, but in that time I thought, that my Unix skills are to low to make it work…



Working with maven and servicemix
Fri, 25 Jul 2008 08:47:11 +0100

Working with maven and servicemix


During my evaluation of servicemix, creating artifacts with maven fucks up. Much commands which must be known or if not, you have to look at servicemix FAQs and so on. So I eased up the use by creating a little shell script which allows me to create project directorys, ServiceUnits and ServiceAssemblies. To use the script you need Maven2.x (I’ve used version 2.0.8) because the script encapsulates all maven commands which are needed to do create the named units. So here it is:



My cousin is under the 'cap'...

My cousin is under the 'cap'…


… transfering german sayings into english roxx 🙂 Jear last weakend we (Kim, Rainer, Kerstin and me) were at the wedding of my cousin Anne. I think it was the loveliest wedding were I ever was invited (ok, that aren’t so much but I think for the coming weddings it will be hard to beat that). But let me start on the beginning.


I started in Mannheim at 5:33 pm and had much luck because there was an ICE accident on Thursday evening (I think it was there, maybe it was ealier) and much of the ICE’s coming from Cologne has a delay. So even the ICE what I decided to use. But my luck was, that the ICE which was schedduled for 16.33 had one hour delay so it arrives when I was at Manheim main station 🙂 It was a little bit cramed but I was in and started to go to Ulm. Where I arrived at ca. 7.13 pm. Sadly I missed my follow up train that should bring me to Herbrechtingen. So I had to wait for 45 minnutes. When I was there my cousin Florian picks me up there an we drove to the hotel where I had booked a room. At the evening we were in a pizzeria in the same town (What a funny evening 😀 don’t give Rainer a flapper). On satuarday was the wedding. So after breakfirst we drove to the church in Herbrechtingen.



What the fuck is an Enterprise Service Bus (ESB)
Wed, 09 Jul 2008 08:47:11 +0100

What the fuck is an Enterprise Service Bus (ESB)


Today we’ve thought about an ESB. We started by decomposing the whole term of Enterprise Service Bus:


Enterprise – What is an enterprise? So in my opinion an enterprise is a organisation, which creates output or an service or something like that.
Service – What is an service? I think we will use here a commonly used definition:
“A unit of work done by a service provider to achieve desired end results for a service consumer.”
Bus – What is an Bus? A bus is a vehicle, that stops at the bus stop when there are people that like to come in or go out of the bus.
So well what do we have at all? A bus, which drives in service of an enterprise. This means it might carry people from home to the company where they work (in other direction too). So this is an ESB. So what are the enterprises which offer an ESB? One of them is SAP from germany/Waldorf:

Customized my Blog


As you can see, I’ve customized my blog and created my own theme… which is not finished at all, but for the first time it will fit my requirements. Also I’ve added a plugin which enables the blog to highlight source code from different programming languages. This plugin is called wp-syntax. Here are some examples:
First of all PHP:



<?php
function hello($strName) {
 echo "Hello $strName";
}
?>
