AlmaLinux – Made For Cloud

AlmaLinux 10 – Install docker-ce

You can read lots of blogs about this. This is the simple minimal version

Assuming you’re doing everything as root, but if you aren’t then prefix these commands with sudo as appropriate for your environment.

dnf config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
dnf install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
systemctl enable --now docker

That’s it. Done. Now if you want to allow non-root users to use docker.

 usermod -aG docker user   # user is the non-root user you want to be able to use docker

AlmaLinux 9 & Centos 9 Stream builds can now be created for oVirt Nodes

gocallag — Sun, 23 Feb 2025 02:50:24 +0000

When PR https://github.com/oVirt/ovirt-node-ng-image/pull/146 lands you will be able to build oVirt nodes using AlmaLinux 9 (new) and Centos 9 Stream (fixed).

There are still a few issues with AlmaLinux 9, not because of AlmaLinux, but because the oVirt engine force enables a bunch of Centos 9 Stream repositories breaking the system. You can get around this by basically disabling those repositories in /etc/yum.repos.d/ as they appear – bugs will be filed with the engine.

Converting from CentOS 8 to AlmaLinux 8

gocallag — Tue, 12 Jul 2022 05:06:15 +0000

This is more so that I can remember.

You need to get to the latest update level on the CentOS systems. If the systems have been unloved you will likely find that they can no longer access the repos servers.

Change the baseurl to http://vault.centos.org/, comment out the mirrorlist as per this image.

You’ll need to do this in at least :

/etc/yum.repos.d/CentOS-Linux-BaseOS.repo
/etc/yum.repos.d/CentOS-Linux-AppStream.repo

Then you can perform the required upgrade :

dnf update
dnf upgrade

Then I suggest re-booting and you can then perform the AlmaLinux migration by :

curl -O https://raw.githubusercontent.com/AlmaLinux/almalinux-deploy/master/almalinux-deploy.sh
bash almalinux-deploy.sh

Then the following should show that you’ve converted OK

cat /etc/os-release
