# Packages can be installed from any enabled yum repo on the image.
# RPMfusion repos are available by default in ublue main images
# List of rpmfusion packages can be found here:
# https://mirrors.rpmfusion.org/mirrorlist?path=free/fedora/updates/39/x86_64/repoview/index.html&protocol=https&redirect=1

# this installs a package from fedora repos
dnf install -y kubernetes1.32 kata-containers cri-o1.32 dbus dbus-daemon dbus-broker
dnf remove -y moby-engine docker-cli

# Use a COPR Example:
#
# dnf5 -y copr enable ublue-os/staging
# dnf5 -y install package
# Disable COPRs so they don't end up enabled on the final image:
# dnf5 -y copr disable ublue-os/staging
