I have followed the directions on the k3s official site, but cannot seem to get rid of the errors around selinux. ```auto [ec2-user]$ INSTALL_K3S_SKIP_DOWNLOAD=true INSTALL_K3S_EXEC="--write-kubeconfig-mode 644" INSTALL_K3S_SKIP_SELINUX_RPM=true INSTALL_K3S_SELINUX_WARN=true INSTALL_K3S_EXEC="--disable traefik" ./install.sh [INFO] Skipping k3s download and verify [INFO] Skipping installation of SELinux RPM [WARN] Failed to find the k3s-selinux policy, please install: dnf install -y container-selinux dnf install -y https://rpm.rancher.io/k3s/stable/common/centos/8/noarch/ [INFO] Creating /usr/local/bin/kubectl symlink to k3s [INFO] Creating /usr/local/bin/crictl symlink to k3s [INFO] Creating /usr/local/bin/ctr symlink to k3s [INFO] Creating killall script /usr/local/bin/k3s-killall.sh [INFO] Creating uninstall script /usr/local/bin/k3s-uninstall.sh [INFO] env: Creating environment file /etc/systemd/system/k3s.service.env [INFO] systemd: Creating service file /etc/systemd/system/k3s.service [INFO] systemd: Enabling k3s unit Created symlink /etc/systemd/system/multi-user.target.wants/k3s.service → /etc/systemd/system/k3s.service.

@acatkrom Hi, just tried your notes/links on openSUSE MicroOS, with some of the leg work done via combustion… All good here… but I did install the k3s-selinux rpm and a seed-token during the combustion run, and added node ip address to the EXEC options; ```bash INSTALL_K3S_SKIP_DOWNLOAD=true INSTALL_K3S_SKIP_SELINUX_RPM=true INSTALL_K3S_SELINUX_WARN=true \ > INSTALL_K3S_EXEC="--write-kubeconfig-mode 644 --disable traefik --node-ip=192.xxx.xxx.141 --node-external-ip=192.xxx.xxx.141" \ > /root/bin/install.sh [INFO] Skipping k3s download and verify [INFO] Skipping installation of SELinux RPM [INFO] Creating /usr/local/bin/kubectl symlink to k3s [INFO] Creating /usr/local/bin/crictl symlink to k3s [INFO] Creating /usr/local/bin/ctr symlink to k3s [INFO] Creating killall script /usr/local/bin/k3s-killall.sh [INFO] Creating uninstall script /usr/local/bin/k3s-uninstall.sh [INFO] env: Creating environment file /etc/systemd/system/k3s.service.env [INFO] systemd: Creating service file /etc/systemd/system/k3s.service [INFO] systemd: Enabling k3s unit Created symlink /etc/systemd/system/multi-user.target.wants/k3s.service → /etc/systemd/system/k3s.service.

Thanks!! A little more background the machine is running RHEL 8.8 on aws I did install k3s-selinux as shown in the link, before trying to install k3s Going through the logs, and researching it seemed to be erroring out because nm-cloud-setup.service was up, so I disabled that service with `sudo systemctl disable nm-cloud-setup.service` I restarted the k3s service with `sudo systemctl restart k3s.service` ```auto [ec2-user@ip-~]$ kubectl get all NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE service/kubernetes ClusterIP 10.43.0.1 443/TCP 16h ``` Next big question is “what is the nm-cloud-setup service” and “do we need it” ---
