Having trouble installing Docker

Completely new to Fedora - so unfamiliar with dnf/rpm-ostree. Not even 100% sure what rpm-ostree is....

Anyways - https://docs.docker.com/engine/install/fedora/

 sudo dnf -y install dnf-plugins-core

 sudo dnf -y install dnf-plugins-core

appears to install without any issues, but

sudo dnf config-manager --add-repo https://download.docker.com/linux/fedora/docker-ce.repo

sudo dnf config-manager --add-repo https://download.docker.com/linux/fedora/docker-ce.repo

doesn't recognize

config-manager

config-manager

error: unrecognized subcommand 'config-manager'

Usage: yum [OPTIONS] <COMMAND>

error: unrecognized subcommand 'config-manager'

Usage: yum [OPTIONS] <COMMAND>

If I run

dnf install dng-plugins-core

dnf install dng-plugins-core

again, it seems like it's requested but not installed based off the message?

sudo dnf install dnf-plugins-core
Note: This system is image (rpm-ostree) based.
error: Package/capability 'dnf-plugins-core' is already requested

sudo dnf install dnf-plugins-core
Note: This system is image (rpm-ostree) based.
error: Package/capability 'dnf-plugins-core' is already requested

any thoughts?

Install Docker Engine on Fedora

Learn how to install Docker Engine on Fedora. These instructions cover the different installation methods, how to uninstall, and next steps.

Solution

Yup in the ticket there were docker instructions that needed to be changed slightly to work with podman. So far podman seems to be much faster than docker from my testing. If you are looking at a development machine though, Aurora or Bluefin are worth checking out. Those images come with both podman and docker preinstalled. It also has things like preinstalled virtual-machine manager etc with instructions on using homebrew

Podman comes preinstalled on Bazzite. you can pretty much replace the keyword with and with you sometimes have to change anything using volumes to have a :rw or :Z at the end though

Have a look at this ticket for reference https://github.com/ublue-os/bazzite/issues/1124#issuecomment-2110645879

I’ll look into it; thank you. I’ve considered trying podman in the past for work but never pulled the trigger. This will be a good opportunity.

Curious though, if you know anything about the “why”/errors - for my own knowledge. Will/could I have similar issues with other packages in the future?

Since I got the error in prereq packages, not docker itself

(And sorry if that’s what the ticket ref was for, driving so haven’t read through the issue)

I’m not sure I am with this machine, it’s mostly for gaming but casual dev. I don’t do much dev in my free time after work much these days anymore lol
