First Time Fedora

Just read the news that Fedora released 37, with the (almost) latest Linux kernel 6.0.7. That’s very brave and new, I must try it!

I heard that you must upgrade your system for at most 9 months, and I think this is not a problem for me, I don’t have any severe business running on any server, all my servers are dev-only.

The software packager dnf has a very new repo of packages, e.g. for neovim I can just run dnf install neovim and it will install the latest one to my system. I can’t imagine when using Ubuntu.

packages installed

• zsh
• neovim
• make cmake gcc-c++
• htop
• util-linux-user

After maybe 4 hours of using of the Fedora Desktop, I installed a server image instead to further check the difference from Ubuntu.

Fedora CoreOS(Dec-2022)

When I was reviewing my cloud services and VM usage found that my AWS EC2 3 years Reserved Instances was about to expired, I didn’t use it as much as I expected, it’s a t3.small instance and the disk doesn’t come with the reserved plan hence I attached 16GB disk to is, the total cost is about $11/month and I mainly used it for my proxy service.

Since I am more comfortable with GCP now, so I will replace it with a GCP VM. The normal compute engine prices are similar since my requirements are very clear now: just a proxy server to serve my normal daytime usage. So I will go with a SPOT VM, which is so cheap and I don’t have anything to lose if it suddenly is deleted, and I only need it in the daytime.

It takes several hours to finalize a script like this, it’s mainly because CoreOS only accept ed25519 type ssh key, and you need to know the default username core.

But after login in and trying to install tools with dnf or yum, just released that both are not installed and that is intended. But it has docker installed! Now I just need the core user to use docker by sudo usermod -aG docker $USER and I can almost do anything on it.
