Minikube：mount（2）系统调用失败：连接被拒绝

时间：2019-07-23 20:44:22

标签： macos kubernetes minikube

试图将本地驱动器安装到我的minikube主机上（似乎是对此thread的复制，但未提供解决方案...）

使用：

OSX 10.14.3和minikube（使用HyperVisor）

$ minikube mount --ip 192.168.64.5 --v=7 ~/Documents/projects/docker_storage/tf:/mnt/vda1/data/tf

期望挂载映射从local：host映射，但是连接被拒绝。可能是某些防火墙或代理问题？

2 个答案:

答案 0 :(得分：0)

简而言之，可能的解决方案是将minikube更新为最新版本。您可能还需要使用minikube delete命令删除minikube VM，并使用brew upgrade && brew cask upgrade

更新其他软件，例如docker

update2 ：可能出现连接问题的另一个原因是因为使用了错误的ufs服务器IP，该IP通常是特定虚拟子网中的主机IP地址，这对于不同的虚拟环境是不同的。对于hyperkit vm-driver，它是192.168.64.1，对于虚拟盒vm-driver，它是192.168.99.1，因为我已经更改了virtualbox网络默认IP子网（192.168.56.0/24）。完全不指定--ip参数的情况下，它也可以正常工作。请查看下面的详细信息。

其余的答案包含使用不同的vm-drivers和minikube参数的实验结果。

因此，将文件夹共享到minikube VM在 OSX v10.14.3 和 minikube v0.35.0 上效果很好。我已经针对--vm-driver=virtualbox和--vm-driver=hyperkit进行了测试。

更新：我还使用了最新版本的minikube（ v1.2.0 ）和vm-driver-{{1} }和hyperkit，它的工作方式与旧版minikube完全相同，如下所述。日志消息略有不同。

以下是结果：

您必须安装virtualbox才能使用virtualbox vm-driver运行minikube： 
virtualbox

-vm-driver = virtualbox：

$ brew cask install virtualbox
$ brew cask install virtualbox-extension-pack

未指定--ip的共享文件夹：

$ minikube start   # --vm-driver=virtualbox is default
我在单独的终端窗口中运行这些命令，因为在使用它时必须保持ufs服务器运行。 
$ minikube mount --v=7 /Users/some_username/temp/minikube/mkshared/:/mnt/mkshared

?  Mounting /Users/some_username/temp/minikube/mkshared/ into /mnt/mkshared on the minikube VM
?  This daemon process needs to stay alive for the mount to be accessible ...

请注意，ufs服务器IP地址是自动检测到的。我在下一个实验中使用它作为命令行参数--ip的值。

指定了--ip的共享文件夹：

host-vm$ minikube ssh
minikube-vm# mount

访问共享文件夹中的现有内容以及创建新文件都可以正常工作，在minikube VM中创建文件后，即可在主机目录中同时使用这些文件。

由于我在Fedora 32上遇到过类似的问题，因此我将其留在这里：

mount failed: mount with cmd /bin/bash -c "sudo mount -t 9p -o dfltgid=$(grep ^docker: /etc/group | cut -d: -f3),dfltuid=$(id -u docker),msize=262144,port=38811,trans=tcp,version=9p2000.L 192.168.39.1 /data/pvtheme" : /bin/bash -c "sudo mount -t 9p -o dfltgid=$(grep ^docker: /etc/group | cut -d: -f3),dfltuid=$(id -u docker),msize=262144,port=38811,trans=tcp,version=9p2000.L 192.168.39.1 /data/pvtheme": Process exited with status 32
stdout:

stderr:
mount: /data/pvtheme: mount(2) system call failed: Connection refused.

我通过以下评论解决了问题：https://github.com/kubernetes/minikube/issues/4726#issuecomment-510217223

这是一个firewalld问题：

$ sudo firewall-cmd --permanent --zone=libvirt --add-rich-rule='rule family="ipv4" source address="192.168.39.0/24" accept'

$ sudo firewall-cmd --reload

更改后，这是我的firewalld配置：

firewall-cmd --zone=libvirt --list-all
libvirt (active)
  target: ACCEPT
  icmp-block-inversion: no
  interfaces: crc virbr0 virbr1
  sources: 
  services: dhcp dhcpv6 dns ssh tftp
  ports: 
  protocols: icmp ipv6-icmp
  masquerade: no
  forward-ports: 
  source-ports: 
  icmp-blocks: 
  rich rules: 
    rule family="ipv4" source address="192.168.39.0/24" accept
    rule priority="32767" reject
