无法在Vagrant上安装Kubernetes [英] Can't install Kubernetes on Vagrant

问题描述

使用本指南在Vagrant集群上安装Kubernetes：

Use this guide to install Kubernetes on Vagrant cluster:

https://kubernetes.io/docs/getting-started-guides/kubeadm/

在（2/4）初始化您的母版，出现一些错误：

[root@localhost ~]# kubeadm init
[kubeadm] WARNING: kubeadm is in beta, please do not use it for production clusters.
[init] Using Kubernetes version: v1.6.4
[init] Using Authorization mode: RBAC
[preflight] Running pre-flight checks
[preflight] Some fatal errors occurred:
    /proc/sys/net/bridge/bridge-nf-call-iptables contents are not set to 1
[preflight] If you know what you are doing, you can skip pre-flight checks with `--skip-preflight-checks`

我检查了 / proc / sys / net / bridge / bridge-nf-call-iptables 文件内容，其中只有一个 0 。

I checked the /proc/sys/net/bridge/bridge-nf-call-iptables file content, there is only one 0 in it.

在（3/4）安装Pod网络时，我下载了 kube-flannel 文件：

https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

然后运行 kubectl apply -f kube-flannel.yml ，出现错误：

[root@localhost ~]# kubectl apply -f kube-flannel.yml
The connection to the server localhost:8080 was refused - did you specify the right host or port?

直到这里，我都不知道该怎么做。

Until here, I don't know how to goon.

我的 Vagrantfile ：

  # Master Server
  config.vm.define "master", primary: true do |master|
    master.vm.network :private_network, ip: "192.168.33.200"
    master.vm.network :forwarded_port, guest: 22, host: 1234, id: 'ssh'
  end

推荐答案

为了设置 / proc / sys / net / bridge / bridge-nf-call-iptables ，方法是编辑 /etc/sysctl.conf 。在那里，您可以添加[1]

In order to set /proc/sys/net/bridge/bridge-nf-call-iptables by editing /etc/sysctl.conf. There you can add [1]

net.bridge.bridge-nf-call-iptables = 1

然后执行

sudo sysctl -p

更改将被应用。
