NextDNS + DNSMasq DHCP and local names

Took me a little bit a while to figure out so here is some documentation, My router from my ISP which is generally pretty good, doesn’t support local dns names which is annoying in itself. Combined with NextDNS, I have no way to identify the devices on my network. So there I went configured dnsmasq on my tiny raspbery-pi : port=5353 no-resolv interface=eth0 except-interface=lo listen-address=::1,192.168.0.3 no-dhcp-interface= bind-interfaces cache-size=10000 local-ttl=2 log-async log-queries bogus-priv server=192....

batzconverter – A multiple timezone converter

I do write a lot of scripts to automate my day to day workflow, some of them I just wrote for 3h to save me 5mn time only once and some others I write in about 5mn but save me hours and hour of productivity. The script showed today, that I am proud of because of its usefulness and probably not of its code, is called “batzconverter” available on https://github.com/chmouel/batzconverter. What the script is trying to solve is when you work with your team spread around 3/4 timezones, how do you schedule a meeting easily....

Building packages for multiple distros on launchpad with docker

I have been trying to build some packages for the ubuntu distros for a new program I have released, gnome-next-meeting-applet In short, it what quite painful! if you are quite new to the launchpad and debian packaging ways (which I wasn’t and yet It took me some time to figure out) you can get quite lost. I got to say that the fedora copr experience is much smoother. After a couple of frustrated google and stackoverflow searches and multiple tries I finally figured out a script that builds and upload properly to launchpad via docker to make it available to my users....

Tekton yaml templates and script feature

Don’t you love “yaml”, yes you do ! or at least that’s what the industry told you to love! When you were in school your teacher told you about “XML” and how it will solve all the industry problems (and there was many in the late 90s). But you learned that you hate reaching to your "<" and" ">" keys and rather have something else. So then the industry came up with “json” so computer or yourself can talk to each others, that’s nice for computers but actually not so nice for yourself it was actually a lie and was not made for yourself to read and write but only for comptures....

Deploying minishift on a remote laptop.

Part of my new job working with Fabric8 is to having it deployed via minishift. Everything is nice and working (try it it’s awesome https://fabric8.io/guide/getStarted/gofabric8.html) as long you deploy it on your local workstation. The thing is that my desktop macosx laptop has only 8GB of RAM and is not very well up to the task to get all the services being deployed when I have my web browser and other stuff hogging the memory....

Getting a letsencrypt SSL certificate for the OpenShift console and API

By default when you install an OpenShift install it would automatically generate its own certificates. It uses those certificates for communication between nodes and as well to automatically auth the admin account. By default those same certificates are the one provided for the OpenShift console and API. Since it is auto generated you will when connecting to the website with you webbrowser get an ugly error message : and as the error message says that’s not very secure #sadpanda....

How to view openshift router (haproxy) stats

After you have installed your fancy openshift install and that it kicked the haproxy router automatically after install you may want to see the stats of the router. The HAproxy stats are exposed on the port 1936 where the router is located (usually on the master node) so first you need a way to access it. You can open it via your firewall (not ideal) or you can just port forward the port to your workstation via SSH :...
