#ITByte: #Containerization is a way to package up an application and its dependencies so that it can run reliably across different computing environments.

This allows developers to build and deploy applications faster and more consistently, regardless of the underlying infrastructure.

@GuillaumeRossolini May I ask which OS your server runs on? What do you use for the "container"ization? (I do see Docker runs containers and they have a GUI called Docker Desktop)

Asking bc my simple setup has most staged websites in /var/www/html under a subfolder. All sites/subfolders in var/www/html are accessible tp the outside world via A DynDNS address -- mysiteexample.endofinternet.net:8008/mywebsitefolder

What Has Docker Become?

I took the time to learn quadlet and that replaced docker-compose (podman-compose) which is great, but what is hard and haven't understood is UID/GID mapping for podman. Like with root it seems to be as easy as docker but podman should be done rootless and the way to map without root is so hard. Crossing my fingers I can figure this out.

#Podman #DockerCompose #Docker #PodmanCompose #FOSS #Containers #Containerization #Linux

New post out on my workflow using Podman and Systemd to create and manage rootless containers! Hopefully y'all find this useful, I use this when deploying small apps that I want to maintain long-term without having to manage physical machines or Linux configuration.

Really exciting that we live in a world where my own infrastructure running on old Dell OptiPlex machines can be managed as easily as containers in AWS!

I took a look at the Dockerfiles for building the immich containers and I'm glad they ship it as a container image.

Wasn't looking forward to install, configure and keep the shaky nodejs stuff running say on a Ubuntu VM natively.

You are free to do that though, if you're a masochist and/or despise containers.

Take a look at the Dockerfile in their repo, run docker inspect on the builder base image mentioned there to get which distribution image they used and what they've added to it, then follow everything you see in the Dockerfile with apt or dnf, etc on your VM.

And then try to keep this Jenga tower of libraries and versions upright through every OS update.

🚀💡 "Thinking about Kubernetes" is apparently the new #zen meditation, where you channel your inner container monk while pondering a type system. 🤔✨ Meanwhile, the rest of us are left wondering if #Kubernetes is just a glorified way to say, "I wish my servers would magically do what I want." 🧙‍♂️🖥️

Giải thích ngắn gọn về mạng Docker: Các container chia sẻ mạng có thể giao tiếp với nhau qua tên (DNS). Reverse proxy (như Nginx) điều hướng traffic, còn Pangolin trên VPS cần kết nối qua cổng mạng công khai.

So, I'm thinking about spending the winter break migrating my NAS from Truenas Core to plain FreeBSD, since IX Systems shit the bed.

Truenas uses iocage, which I know is long dead. What's the current best practice for managing jails?

Tired of Docker Desktop’s license limits? 😩

If you’re building AI agents or data apps in an enterprise environment, you need containers — but Docker Desktop might not be an option.

I just published a quick guide showing how to replace Docker with Podman — fully compatible, open-source, and perfect for running your LLM-driven code safely in containers.

Fast setup, no license issues, same Docker commands.
