问题描述:
kube-proxy-arg如何在/etc/rancher/k3s/config.yaml添加多个参数？
kube-proxy-arg: proxy-mode=ipvs,masquerade-all=true 的方式不正确
复现步骤:
- 安装 K3s 的命令:
安装方式如下
mkdir -p /etc/rancher/k3s/
cat > /etc/rancher/k3s/config.yaml <<EOF
write-kubeconfig-mode: 644
write-kubeconfig: /root/.kube/config
token: "token-12345"
cluster-cidr: 192.168.0.0/16
service-cidr: 172.18.0.0/16
kubelet-arg: eviction-hard=imagefs.available<25%,memory.available<25%,nodefs.available<25%
kube-proxy-arg: proxy-mode=ipvs
EOF
K3S_CONFIG_FILE=/etc/rancher/k3s/config.yaml curl -sfL http://rancher-mirror.cnrancher.com/k3s/k3s-install.sh | INSTALL_K3S_MIRROR=cn sh -
可以正常安装启动
如果修改配置文件把kube-proxy-arg: proxy-mode=ipvs 改成kube-proxy-arg: proxy-mode=ipvs,masquerade-all=true
重启k3s服务就无法启动
附加上下文/日志:
/var/log/messages日志提示如下
Error: failed validate: KubeProxyConfiguration.Mode.ProxyMode: Invalid value: "ipvs masquerade-all=true": must be iptables,ipvs,userspace or blank (blank means the best-available proxy [currently iptables])
