一、安装
cat > k3s.start.sh << \EOF
./k3s server --docker \
--disable traefik \
--kubelet-arg cgroup-driver=systemd \
--node-ip 192.168.37.101 \
--node-name node1
EOF
二、获取配置
ln -s /etc/rancher/k3s/k3s.yaml .kube/config
三、卸载
cat > k3s-uninstall.sh << \EOF
#!/bin/sh
set -x
[ $(id -u) -eq 0 ] || exec sudo $0 $@
/usr/local/bin/k3s-killall.sh
if command -v systemctl; then
systemctl disable k3s
systemctl reset-failed k3s
systemctl daemon-reload
fi
if command -v rc-update; then
rc-update delete k3s default
fi
rm -f /etc/systemd/system/k3s.service
rm -f /etc/systemd/system/k3s.service.env
remove_uninstall() {
rm -f /usr/local/bin/k3s-uninstall.sh
}
trap remove_uninstall EXIT
if (ls /etc/systemd/system/k3s*.service || ls /etc/init.d/k3s*) >/dev/null 2>&1; then
set +x; echo 'Additional k3s services installed, skipping uninstall of k3s'; set -x
exit
fi
rm -rf /etc/rancher/k3s
rm -rf /run/k3s
rm -rf /run/flannel
rm -rf /var/lib/rancher/k3s
rm -rf /var/lib/kubelet
rm -f /usr/local/bin/k3s
rm -f /usr/local/bin/k3s-killall.sh
if type yum >/dev/null 2>&1; then
yum remove -y k3s-selinux
rm -f /etc/yum.repos.d/rancher-k3s-common*.repo
elif type zypper >/dev/null 2>&1; then
uninstall_cmd="zypper remove -y k3s-selinux"
if [ "${TRANSACTIONAL_UPDATE=false}" != "true" ] && [ -x /usr/sbin/transactional-update ]; then
uninstall_cmd="transactional-update --no-selfupdate -d run $uninstall_cmd"
fi
$uninstall_cmd
rm -f /etc/zypp/repos.d/rancher-k3s-common*.repo
fi
