Я хочу установить kubernetes на centos 7. Я установил kubeadm и использую kubeadm для установки kubernetes. kubeadm init ошибка:
error execution phase preflight: [preflight] Some fatal errors occurred:
[ERROR FileContent--proc-sys-net-bridge-bridge-nf-call-iptables]: /proc/sys/net/bridge/bridge-nf-call-iptables does not exist
[ERROR SystemVerification]: failed to parse kernel config: unable to load kernel module: "configs", output: "", err: exit status 1
[ERROR SystemVerification]: unsupported graph driver: vfs
[preflight] If you know what you are doing, you can make a check non-fatal with `--ignore-preflight-errors=...`
затем я запускаю команду mkdir /proc/sys/net/bridge и получаю ошибку mkdir: cannot create directory ‘/proc/sys/net/bridge’: No such file or directory. Как исправить?
