如何启动minikube? [英] How to start minikube?
问题描述
我在Thinkpad X201i的Linux机器上的Lubuntu 16.04上安装了minikube.
I installed minikube on my Linux box Lubuntu 16.04 on a Thinkpad X201i.
这是我完整的安装步骤:
Here are my complete install steps:
Download and install the minikube server
cd programs/install/bin
curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64;
chmod +x minikube;
Download and install the kubectl client
cd programs/install/bin
curl -Lo kubectl https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl
chmod +x kubectl;
Install the libraries libvirt and qemu-kvm
sudo apt-get install libvirt-bin qemu-kvm
(NOTE: For Ubuntu 17.04 change the group to libvirt)
sudo usermod -a -G libvirtd $(whoami)
newgrp libvirtd
Install Docker Machine
cd /home/stephane/programs/install/bin
curl -L https://github.com/docker/machine/releases/download/v0.12.2/docker-machine-`uname -s`-`uname -m` > docker-machine;
chmod +x docker-machine
Install the KVM driver for Docker Machine
cd /home/stephane/programs/install/bin
curl -L https://github.com/dhiltgen/docker-machine-kvm/releases/download/v0.10.0/docker-machine-driver-kvm-ubuntu16.04 > docker-machine-driver-kvm;
chmod +x docker-machine-driver-kvm
在系统重新启动时，群集似乎已启动:
On system reboot, the cluster seems to be started:
$ kubectl cluster-info
Kubernetes master is running at http://localhost:8080
$ minikube ip
$
对此我感到很惊讶，因为我没有为其启动创建任何服务.
I'm surprised about that, since I did not create any service for it to start.
如果启动了，那为什么没有IP?
And if it is started, then why is there no IP ?
我在/etc/init.d/目录中查找:
$ ll -t /etc/init.d/*virt*
-rwxr-xr-x 1 root 17K août 23 14:47 /etc/init.d/libvirt-guests*
-rwxr-xr-x 1 root 5,9K août 11 07:50 /etc/init.d/libvirt-bin*
-rwxr-xr-x 1 root 4,0K août 11 07:50 /etc/init.d/virtlockd*
-rwxr-xr-x 1 root 3,9K août 11 07:50 /etc/init.d/virtlogd*
$ ll -t /etc/init.d/docker
-rwxr-xr-x 1 root 3,8K mai 4 23:36 /etc/init.d/docker*
它不能是启动我的minikube的docker守护进程，因为我的docker中没有映像:
It can't be the docker deamon that starts my minikube as there are no image in my docker:
$ docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
起初，我正在考虑手动启动它.
At first, I was thinking of manually starting it.
但是，当我这样做时，它表示尝试启动，但是由于查找不存在的图像而失败:
But when I do so, it shows an attempt to start, but fails as it looks up an image that does not exist:
$ minikube start --vm-driver kvm
Starting local Kubernetes v1.7.5 cluster...
Starting VM...
E0912 18:23:37.989448 24423 start.go:143] Error starting host: Error starting stopped host: virError(Code=38, Domain=18, Message='Cannot access storage file '/root/.minikube/machines/minikube/boot2docker.iso' (as uid:64055, gid:129): Aucun fichier ou dossier de ce type').
我配置了BIOS并启用了虚拟化，并且确实启用了加速功能
I configured the BIOS and enabled the Virtualization and I do have accelaration enabled:
$ sudo /usr/sbin/kvm-ok
INFO: /dev/kvm exists
KVM acceleration can be used
我承认我将库安装在非标准目录位置:
/home/stephane/programs/install/bin
I admit I installed the libraries in a non standard directory location:
/home/stephane/programs/install/bin
一些不同命令的输出:
$ egrep -c '(vmx|svm)' /proc/cpuinfo
4
$ virsh list --all
ID Nom État
----------------------------------------------------
它仍然说它正在运行:
$ kubectl cluster-info
Kubernetes master is running at http://localhost:8080
尽管无法连接:
$ kubectl cluster-info dump
The connection to the server localhost:8080 was refused - did you specify the right host or port?
为什么最后两个类似的命令给出相反的信号?
Why are these last two similar commands, giving such opposite signal ?
更新:我在rm -rf ~/.minikube/cache命令中键入了几次，然后在minikube start --vm-driver kvm命令中键入了几次，今天看来可以使用了:
UPDATE: I typed in the rm -rf ~/.minikube/cache command followed by the minikube start --vm-driver kvm command a few times, and today it seemed to work:
$ minikube start --vm-driver kvm
Starting local Kubernetes v1.7.5 cluster...
Starting VM...

推荐答案
看看docker守护进程(docker ps)上运行的容器，kubernetes肯定在那里运行.
Have a look to the containers running on your docker daemon (docker ps), kubernetes is certainly running there.
我从未在Linux上测试过minikube，所以不确定，但是在Windows上，它作为Linux vm中的容器运行.
I never tested minikube on linux so I'm not sure, but on windows, it runs as containers inside a linux vm.
