centos7.5安装minikube kubernetes

前提：已安装centos7.5安装VirtualBox

Minikube是什么？
Minikube是一种方便在本地运行Kubernetes的工具. 
Minikube 是可以在VM中运行单节点的Kubernetes集群. 
Minikube是为了开发或测试在本地启动一个节点的kubernetes集群.

特点
不能启动生产集群，没有高可用性的单节点机器. 
可以工作在Windows,Linux,MacOS下

1.安装minikube

[root@localhost ~]# curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
 38.2M   38.2M            671k        ::  :: --:--:-- 1640k

2.安装kubectl

[root@localhost yum.repos.d]# curl -Lo kubectl https://storage.googleapis.com/kubernetes-release/release/v1.10.3/bin/linux/amd64/kubectl && chmod +x kubectl
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
 51.7M   51.7M           1421k        ::  :: --:--:-- 1762k
[root@localhost yum.repos.d]# mv kubectl /usr/local/bin/

此处获取稳定版本可直接在浏览器IE中输入https://storage.googleapis.com/kubernetes-release/release/stable.txt

3.配置变量

root@localhost network-scripts]# export MINIKUBE_WANTUPDATENOTIFICATION=false
[root@localhost network-scripts]# export MINIKUBE_WANTREPORTERRORPROMPT=false
[root@localhost network-scripts]# export MINIKUBE_HOME=$HOME
[root@localhost network-scripts]# export CHANGE_MINIKUBE_NONE_USER=true
[root@localhost network-scripts]# mkdir $HOME/.kube || true
mkdir: cannot create directory ‘/root/.kube’: File exists
[root@localhost network-scripts]# touch $HOME/.kube/config
[root@localhost network-scripts]# export KUBECONFIG=$HOME/.kube/config
[root@localhost network-scripts]# echo $MINIKUBE_WANTUPDATENOTIFICATION
false
[root@localhost network-scripts]# echo $MINIKUBE_WANTREPORTERRORPROMPT
false[root@localhost network-scripts]# echo $MINIKUBE_HOME
/root
[root@localhost network-scripts]# echo $CHANGE_MINIKUBE_NONE_USER
true
[root@localhost network-scripts]# ls $HOME/.kube/
config
[root@localhost network-scripts]# echo $KUBECONFIG
/root/.kube/config

4.启动minikube

[root@localhost bin]# curl -Lo kubeadm http://storage.googleapis.com/kubernetes-release/release/v1.10.0/bin/linux/amd64/kubeadm
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  149M    149M            731k        ::  :: --:--:-- 1274k
[root@localhost bin]# curl -Lo kubelet http://storage.googleapis.com/kubernetes-release/release/v1.10.0/bin/linux/amd64/kubelet
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  145M    145M           1638k        ::  :: --:--:-- 1762k

[root@localhost bin]# chmod +x ./*
[root@localhost bin]# ll

[root@localhost bin]# pwd
/usr/local/bin

[root@localhost network-scripts]# minikube start --vm-driver=virtualbox
o   minikube v0.35.0 on linux (amd64)
>   Creating virtualbox VM (CPUs=, Memory=2048MB, Disk=20000MB) ...
!   Unable to start VM: create: precreate: This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory

*   Sorry that minikube crashed. If this was unexpected, we would love to hear from you:

保证VMware设置cpu虚拟化，intel VT-x  ThinkCentre进入BIOS,设置intel virtualization technology

重新安装
