Kubeadm初始化报错Swap解决

[ERROR Swap]: running with swap on is not supported. Please disable swap
[preflight] If you know what you are doing, you can make a check non-fatal with `--ignore-preflight-errors=...`

swapoff  -a
sed -ri 's/.*swap.*/#&/' /etc/fstab

在kubeadm初始化时增加--ignore-preflight-errors=Swap参数，注意Swap中S要大写
kubeadm init --ignore-preflight-errors=Swap

sed -i 's/KUBELET_EXTRA_ARGS=/KUBELET_EXTRA_ARGS="--fail-swap-on=false"/' /etc/sysconfig/kubelet
