Today I tried Docker Compose with rootless Podman 3.4.4, and the happy news is that it works 🎉. Podman (and Rootless) had compose support since version 3.0, However I’ve never had luck with it. I’ve tried it again today and it works perfectly. Here are the steps to run compose files using podman rootless. Ditch Docker and install Podman instead. Start the rootless Podman daemon systemctl --user start podman.socket Install compose (download the binary from the release page and put it in a folder figuring in you PATH) curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o ~/.local/bin/docker-compose Get the podman socket path systemctl --user status podman.socket # probably will be in /run/user/userid/podman/podman.sock Get a compose file (get it from awesome compose repo, or make your own) curl https://raw.githubusercontent.com/docker/awesome-compose/master/gitea-postgres/docker-compose.yaml -o docker-compose.yaml Run the compose file docker-compose -H unix:/run/user/1000/podman/podman.sock up And here you are, Hoooray! no need for root to run a docker-compose file! ...

Hello again 👋 I passed CKAD exam last week and here are some takeways Takeways: It is not about prep, it is about how much do you know kubernetes (at the Developer level) and how much do you understand its different concepts. The exam is not hard, in the contrary if you know your Kubernetes, it is the best way to validate you skills and knowledge. It is worth every penny in that sense. You should know how to use a Unix shell (Bash) and also Vim. You should be able to navigate through the filesystem, create files delete files, also know how to edit text using vim. You should be familiar with Kubernetes docs (in particular the kubectl cheat sheet page), and know where to find things. You can use this bookmark list for your chrome. The LF gives 2 killer.sh CKAD simulated exams. I took one, didn’t have a good score, but it helped me to know what to expect. Take your time to read the questions! And if you don’t know the answer flag the question and move on! Learn kubectl imperative commands (run, expose. create …), and keep in mind that you can copy-paste from docs. You have 2 tries, so don’t worry. Use a mouse or a touchpad with the middle button, it will make your life easier, since the terminal does not support copy-paste with (CTRL-C, CTRL-V). You can use CTRL-SHIFT-C and CTRL-SHIFT-V but I prefer not to, to avoid triggering browser keyboard shortcuts.

THS: The Holy Setup - It is series of blog posts about my computer setup. Road to the Valhalla Treat your dotfiles better Life in the Web It’s been a long time since I wrote something in the blog. A lot of things happened since my last blogpost. One of the interesting things that I’ve been into is working on my new setup. This post is the first of a series of articles about my new setup. I’ll share with you the things I added to (and removed from) my workflow, and how they benefited me. ...

It’s not about data, it’s about attention. Most people believe that facebook is selling data to advertisers, and this not true, at least not for small non-governmental advertisers. What facebook is selling is our attention not our data. Facebook uses our data to help match the us to the right products (ads), but it does not actually sell it (our data). Let’s say I use a feed blocker browser extension, will facebook still make money out of me ? No !! Because I won’t see ads, they won’t be able to ship my attention to their clients (advertisers). ...

Hello Again, Throughout the 4 previous months I got the chance to work on php applications again. This time not as a developer, but as an operator. I spent a good part of my internship trying to deploy, run and optimize php apps on my local environment and on the cloud. This post will be in many parts (3 or more). This part will be a sort of introduction to the php ecosystem. We’ll try to build a general overview on the different ways we can deploy a php application. And in the next parts we’ll dive deeper on the process and go through the different solution in the market. ...

Containers are not secure ! I am kidding ! they are pretty secure but they are dangerous and one reason why they are is because they require root privileges to run. Why ? OKey Okey let’s take a look at this: sudo docker run -v /:/hostfs ubuntu rm -rf /hostfs You figured why running docker (container runtime) as root is dangerous ? Running your container runtime as root is the most dangerous thing you can do, because escaping the container barrier (container runtime vulnerability) will make the attacker root and Slat 3enbi. ...

I spent the last week at @ABConseils (The company hosting my internshipi ✌) trying to deploy a two-tier web application (frontend/backend) inside containers. Everything was working fine except for recaptcha. For some reason I couldn’t get it to work on my local setup. I spent two days (on and off) trying to. After struggling a bit with this recaptcha problem I met with the team, and we agreed that in order to test what have been done, we will temporarily remove recaptcha from my local environement and reintegrate it later in next stages. ...
