what is minikube
minikube is a tool to quickly start a virtual machine on a local laptop to build a kubernets single-node kubernetes cluster. Because of some network reasons, I use the minikube modified by Alibaba Cloud here.
Install
First of all, you have to make sure that virtualbox is installed locally. If you are using linux, even virtualbox can directly support the installation of k8s on the host without installation. Then install curl -Lo minikube http://kubernetes.oss-cn-hangzhou.aliyuncs.com/minikube/releases/v0.25.2/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/it. Now execute minikube versionit. If the version of minikube can be displayed, the installation is successful.
The first k8s cluster in my life
The next step is to create a cluster minikube start --vm-driver=virtualbox --registry-mirror=https://registry.docker-cn.com--vm-driver means what virtual machine are you using, because I use virtualbox, so the parameter is virtualbox and --registry-mirror must be added, you know in China
➜ temp minikube start --vm-driver=virtualbox --registry-mirror=https://registry.docker-cn.com

Kubectl is now configured to use the cluster.
Loading cached images from config file.
If you don't have kubectl installed, there will be a prompt saying that kubectl is not installed, then install it, but you need to use the proxy to find a way to download the binary file first proxychains wget https://storage.googleapis.com/kubernetes-release/release/v1.9.4/bin/linux/amd64/kubectl, then give the executable permission chmod +x kubectl, move the path sudo mv kubectl /usr/bin, and then kubectl versionverify whether it is After success, let kubectl use the minikube configuration file and kubectl config use-context minikubethen view the cluster informationkubectl cluster-info
➜ .kube kubectl cluster-info
Kubernetes master is running at https://192.168.99.100:8443
To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
After that, you can visit the ip:8443 of your master node to see if it is successful, and you can also open virtualbox to see if there is a virtual machine called minikube running
Then you check if the containers in the cluster are runningkubectl get pods --all-namespaces
➜ temp kubectl get pods --all-namespaces
NAMESPACE NAME READY STATUS RESTARTS AGE
kube-system kube-addon-manager-minikube 1/1 Running 0 3m
kube-system kube-dns-7cd4f8cd9f-mtkqk 3/3 Running 0 2m
kube-system kubernetes-dashboard-7b7c7bd496-9m9cf 1/1 Running 0 2m
kube-system storage-provisioner 1/1 Running 0 2m
If it is normal, then the status is running, otherwise it shows that the container is being created, which means that there may be some problems with the network. Then use the command minikube dashboardto view the address of your k8s dashboard, which is usually opened directly in the default browser.
