Hello, I've been using CentOS 7 for a few months to run my HPC applications as a learning project during the pandemic. Initially, I thought it could be my daily operating system, but I soon faced challenges with some OpenSource tools needing newer dependencies. After discovering Docker, Moby, and Podman, I decided to adopt containers for these needs. Now, all my commercial software runs smoothly in a CentOS7 environment powered by the latest Fedora 33. Have you experienced similar setups? Stay safe and have a great day!

Absolutely, I use Docker for my servers—it's a smart way to keep everything organized and tidy.

Other container solutions exist beyond Docker and Podman. I've tried Docker once, but I favor full containers with LXD.

I understand this approach isn't the standard Docker way, but it delivers native speed for CPU-intensive, GPU, and memory-heavy apps without the VM overhead or the need to enable GPU passthrough. For example, if I were using SolidWorks, I'd opt for a VM with GPU passthrough instead.

Running applications inside Docker is built-in without extra cost, unless you restrict resources like CPU or memory via cgroups. It offers great convenience for consistent and stable builds, which I mainly rely on during deployments.

LXD-containers differ from VMs, which means my remark isn't directly connected to my previous statement.

LXD supports using VM images as well, which is why I mentioned it first. Should I consider if LXC containers can access host directories, GPU, and display GUI from the host? I’m thinking about giving it a try.

Certainly, I've noticed precise render durations across different setups—CentOS 7 bare installation versus CentOS 7 Docker image. Yes

Host directories and devices are straightforward. Configuring it to show GUI applications on your desktop is a bit more challenging and less intuitive compared to Docker, making LXD-containers a better option if you prefer simplicity. Conversely, while the initial setup may be more complex, LXD-containers offer greater functionality, so the outcome depends on your priorities.
