Quick post for starting a VM inside libvirt as a non-root user. Also contains some useful snippets. I want to start an alpine virt iso (from here) inside kvm through libvirt. But I am sick to run all my virsh commands prefixed with sudo. DISCLAIMER: This will contain some of my conclusions with my partial understanding of those tools. I am quite sure that all of this can be improved, but I don’t have time to invest on this for the moment. Read More...
DISCLAIMER: This is now fixed in git new releases and does not need to be done anymore. I use an old version of alpine in order to have an unpached version of git. I ran into an interesting issue lastly. I wanted to mount a volume inside a container and clone a repo in it. I also wanted to avoid messing with the permissions and pass my user to the container as well. Read More...
Recently, I had to build some project involving a lot of files. Two choices were possible: use a script to build use a Makefile I ended up with a Makefile, which is the best solution I think. As the script has to generate a bunch of files from “source” files. (I have to confess also, I have been a bit influenced by jessfraz with those tweets: here and here) This project also learned me some tricks which can be reused, here is a little list Read More...
For a personal project I want to iPXE boot alpine. I did not found any step by step guide, so I ended up testing multiple solutions until it works. This post is a “copy” of the answer I made here for the netboot.xyz project.
To fix this issue I used a bunch of thread and resources but here are the three main entry used:

Want to understand a bit of how all those things work? Great! I will show you how to boot a container from the internet only through systemd-nspawn Thanks to the CoreOS team (love those guys) a new hub for storing container now exists: quay. The other good news is the ACI, the container image format defined in the App Container (appc) spec. Read More...
I recently messed up my laptop (do not play with /etc/apt/preferences too much!),
and I had to reinstall my distro. I checked my previous article
and noticed some missing informations. So here is a second article of things
I needed to fixup when installing LMDE on my Macbook.
Here is just a small reminder of common bash shortcuts for everyday use: Ctrl + A Go to the beginning of the line you are currently typing on Ctrl + E Go to the end of the line you are currently typing on Ctrl + L Clears the Screen, similar to the clear command Ctrl + U Clears the line before the cursor position. If you are at the end of the line, clears the entire line. Read More...
Here are some options and command I use with curl when dealing with stuff I have to develop. curl -si <ip> # -s is the silent flag, it removes the progress # -i displays the headers curl -X POST -H "Content-Type: application/json" -u "admin:admin" -d '{}' <ip> # -X set up the http method (here POST) # -H set up an header, format is: "header_name: value" # -u support for Basic Auth, format is: "user:password" # -d set up data to send to the server I mostly use those options, the -s is really interesting when you want to grep the content.

I will not install VirtualBox! That’s all (nor VMWare, don’t be ridiculous). But I really like Vagrant, and use it every time I need something closer to a running machine. So, I dig up the internet and found that there is an unofficial support of libvirt. Installation I do not remember where I found the documentation to do this or if I did it by myself, so no link here, just what I do in order to make this work. Read More...
Jenkins is everywhere now, but I really don’t like it. So I am looking at a replacement from day to day. I discovered Gogs an I though that a CI is also a good use case for the Golang language. And I finally found Drone (which was not really difficult as it is mentionned in a ticket on gogs github). So I decided to make them work together in order to test that. Read More...
