snappy
$ sudo zypper --gpg-auto-import-keys refresh
$ sudo zypper dup --from snappy
$ sudo zypper install snapd
2.After installing snapd, enable the systemd unit that manages the main snap communication socket
$ sudo systemctl enable --now snapd.socket
3.Start-up Confirmation
$ sudo systemctl is-active snapd.socket
active
$ sudo systemctl status snapd.socket

4.Create a symbolic link between /var/lib/snapd/snap and /snap
$ sudo ln -s /var/lib/snapd/snap /snap
5.Check snapd and snap command line tool versions
$ snap version
snap 2.76-0.el9
snapd 2.76-0.el9
series 16
ol 9.8
kernel 6.12.0-205.92.4.2.el9uek.x86_64
architecture amd64
6.Install Package
As an example, we will install MicroK8s, a Kubernetes environment building tool developed by Canonical
$ sudo snap install microk8s --classic
microk8s (1.35/stable) v1.35.6 from Canonical✓ installed
7.Check installed packages
$ snap list
オプション「--all」で、無効になっているパッケージも表示することができる
$ snap list --all

MicroK8s is a small, fast, secure, certified Kubernetes distribution that installs on just about
any Linux box. It provides the functionality of core Kubernetes components, in a small footprint,
scalable from a single node to a high-availability production multi-node cluster. Use it for
offline developments, prototyping, testing, CI/CD. It's also great for appliances - develop your
IoT apps for K8s and deploy them to MicroK8s on your boxes.
