Create a k8s standalone environment using minikube

Tip

This blog post mainly records how to use the centos system to install minikube in a local environment. It fills in a lot of problems that may result in failed image download during the installation process, mainly using kubernete 1.12.1, for other different versions, the method is the same.

1. Download the deployment installation package

 
Wget https://storage.googleapis.com/minikube/releases/v0.30.0/minikube-linux-amd64mv minikube-linux-amd64/usr/bin/minikubewget https://dl.k8s.io/v1.12.1/kubernetes-server-linux-amd64.tar.gztar XF kubernetes-server-linux-amd64.tar.gz & CD kubernetes/Server/bin/CP kubectl kubeadm kubelet/usr/local/bin/
 

2. Install docker

UploadDocker-ce-17.03.2.ce-1.el7.centos.x86_64.rpmAndDocker-ce-selinux-17.03.2.ce-1.el7.centos.noarch.rpmTo the server, run the following command to install docker:

Yum install docker-ce-selinux-17.03.2.ce-1.el7.centos.noarch.rpm-yyum install docker-ce-17.03.2.ce-1.el7.centos.x86_64.rpm-y
 

Start the docker service and set docker to start automatically:

 
Systemctl start dockersystemctl enable docker
 

3. Download the docker image of kubernetes

Create the following script:

 
VI auto_pull_images.sh
 

Add the following content to the script:

#! /Bin/bashimages = (kube-proxy-amd64: v1.12.1 kube-scheduler-amd64: v1.12.1 kube-controller-manager-amd64: v1.12.1 kube-apiserver-amd64: v1.12.1 etcd-amd64: 3.2.24 pause-amd64: 3.1 kubernetes-dashboard-amd64: v1.10.0 k8s-dns-sidecar-amd64: 1.14.8 k8s-dns-kube-dns-amd64: 1.14.8k8s-dns-dnsmasq-nanny-amd64: 1.14.8) for imagename in $ {images [@]}; do docker pull mirrorcontainers/$ imagename docker tag mirrorgoogleiners/$ imagename k8s.

IO/k8s-minikube/storage-provisioner: v1.8.1docker RMI registry.cn-hangzhou.aliyuncs.com/anoy/storage-provisioner:v1.8.1

Run the script:

 
Sh auto_pull_images.sh
 

After the script runs successfully, run the following command to confirm that the image is downloaded to the local device:

4. Start the service

Start minikube Cluster

 
Minikube start -- VM-driver = none -- registry-mirror = https://registry.docker-cn.com -- kubernetes-version v1.12.1
 

Start dashboard:

 
Minikube dashboard
 

Add an external access proxy for the dashboard. The IP address here is the local system IP Address:

 
Kubectl proxy -- Port = 8001 -- Address = '10. 0.0.2 '-- accept-hosts =' ^ .*'&
 

Access the dashboard through URL: http: // 10.0.0.2: 8001/API/V1/namespaces/Kube-system/services/HTTP: kubernetes-dashboard:/Proxy.
