K3s: Installation Fails on Fedora 33 IOT Edition

[seanmalloy]

Environmental Info:
K3s Version: v1.18.9+k3s1

Node(s) CPU architecture, OS, and Version: uname -a Linux localhost.localdomain 5.8.15-301.fc33.aarch64 rancher/k3s#1 SMP Thu Oct 15 15:56:58 UTC 2020 aarch64 aarch64 aarch64 GNU/Linux

Cluster Configuration: Single node on Raspberry Pi 4 Running Fedora 33 IOT Edition

Describe the bug:

The k3s installer is failing with the below error on when run on Fedora 33 IOT Edition. Fedora 33 IOT uses the rpm-ostree package manager, not yum. Therefore all yum commands will fail when run on Fedora 33 IOT Edition because yum is not installed.

root@localhost ~]# curl -sfL https://get.k3s.io | sh -
[INFO]  Finding release for channel stable
[INFO]  Using v1.18.9+k3s1 as release
[INFO]  Downloading hash https://github.com/rancher/k3s/releases/download/v1.18.9+k3s1/sha256sum-arm64.txt
[INFO]  Skipping binary downloaded, installed k3s matches hash
main: line 484: yum: command not found

Steps To Reproduce:

Run the k3s installer on Fedora 33 IOT as the root user.

Expected behavior:

I expected the k3s installation script to successfully run on Fedora 33 IOT edition.

Actual behavior:

The installation fails because the install script is trying to run a yum command, but the yum command is not installed.

Additional context / logs:

Looks like I might need to manually install the SELinux RPM packages using rpm-ostree before running the installer script, and then set INSTALL_K3S_SKIP_SELINUX_RPM to true during the install.

Let me know if there if there would be any interest in updating the installer to support rpm-ostree.

We do not support Fedora 33 IOT, and thus I have a PR incoming with additional logic to prevent trying to auto-install the selinux RPMs on Fedora systems
