创建文件夹¶

mkdir -p /etc/rancher/k3s

设置镜像仓库¶

仓库文件：registries.yaml

mirrors:

cp registries.yaml /etc/rancher/k3s

基于docker环境安装¶

curl -sfL https://rancher-mirror.rancher.cn/k3s/k3s-install.sh | INSTALL_K3S_MIRROR=cn sh -s - --docker --etcd-expose-metrics=true --write-kubeconfig ~/.kube/config --write-kubeconfig-mode 644

默认基于containerd安装¶

curl -sfL https://rancher-mirror.rancher.cn/k3s/k3s-install.sh | INSTALL_K3S_MIRROR=cn sh -s - --container-runtime-endpoint tcp://0.0.0.0:10010 --etcd-expose-metrics=true --private-registry="/etc/rancher/k3s/registries.yaml" --write-kubeconfig ~/.kube/config --write-kubeconfig-mode 644 --service-node-port-range 80-65535 --node-ip 124.221.2.29 --node-external-ip 124.221.2.29 --node-name 124.221.2.29

离线安装(下载安装包)¶

INSTALL_K3S_SKIP_DOWNLOAD=true ./install.sh --etcd-expose-metrics=true --private-registry="/etc/rancher/k3s/registries.yaml" --write-kubeconfig ~/.kube/config --write-kubeconfig-mode 644 --service-node-port-range 80-65535 --node-ip 124.221.2.29 --node-external-ip 124.221.2.29

设置代理（如果需要）¶

nohup k3s kubectl proxy --address='0.0.0.0' --accept-hosts='^*$' --port=8002 &

转发dashboard¶

k3s kubectl -n kubernetes-dashboard port-forward svc/kubernetes-dashboard-kong-proxy 8443:443

操作服务¶

启动服务

systemctl start k3s

停止服务

systemctl stop k3s

停止服务

systemctl restart k3s

服务状态

systemctl status k3s

卸载¶

/usr/bin/k3s-uninstall.sh

例如¶

docker环境下安装¶

curl -sfL https://rancher-mirror.rancher.cn/k3s/k3s-install.sh | INSTALL_K3S_MIRROR=cn sh -s - --docker --etcd-expose-metrics=true --private-registry="/etc/rancher/k3s/registries.yaml" --write-kubeconfig ~/.kube/config --write-kubeconfig-mode 644 --service-node-port-range 1-65535 --node-external-ip 211.154.29.176 --node-name 211.154.29.176 --node-ip 211.154.29.176
