如何在RHEL VM上運行minikube？

Question

有沒有辦法在RHEL VM（Hypervisor）上運行Kubernetes minikube？或者有沒有其他方法可以通過單個VM來試用Kubernetes？

要在RHEL CentOS VM上運行minikube，需要先安裝docker和virtualbox，然後再安裝minikube和and kubectl。由於minikube也在虛擬機中運行，因此您需要使用嵌套虛擬化，因此您需要確保在RHEL CentOS VM的BIOS中啓用虛擬化。

一旦你的虛擬機啓動並以root身份運行，SSH和運行以下命令：這裏

# Install docker dependencies 
yum install -y yum-utils device-mapper-persistent-data lvm2 

# Add Docker repo 
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo 
yum install -y docker-ce epel-release wget 
cd /etc/yum.repos.d/ 
wget http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo 
yum update 

重新啓動你的虛擬機，並確保虛擬化在BIOS

# Install EPEL repo, Minikube kubectl etc. 
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm 
yum --enablerepo=epel install dkms 
yum groupinstall "Development Tools" 
yum install -y kernel-devel VirtualBox-5.2 
curl -LO 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 
sudo mv ./kubectl /usr/local/bin/kubectl 
curl -Lo minikube https://storage.googleapis.com/minikube/releases/v0.23.0/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/ 
sudo /sbin/vboxconfig 

# Start the minikube cluster 
minikube start --vm-driver=virtualbox SERVICE_CLUSTER_IP_RANGE="X.X.X.X/24" --container-runtime=docker --extra-config kubelet.EnableCustomMetrics=true 

# Start the dashboard 
minikube dashboard
