Download the image required for Kubernetes from Alibaba Cloud Mirror Service
Execute the following script on your Mac
./load_images.shOn Windows, use PowerShell

TIPS :
On Mac:
If there is a problem during Kubernetes deployment, you can obtain real-time log information through the docker desktop application log:
pred= ' process matches ".*(ocker|vpnkit).*"
|| (process in {"taskgated-helper", "launchservicesd", "kernel"} && eventMessage contains[c] "docker") '
/usr/bin/log stream --style syslog --level=debug --color=always --predicate " $pred "On Windows:
If there is a problem during Kubernetes deployment, you can view the Docker log in service.txt under C:ProgramDataDockerDesktop, and log in log.txt under C:UsersyourUserNameAppDataLocalDocker
Problem diagnosis :
If you see that Kubernetes is always starting, please refer to
rm -fr '~/Library/Group Containers/group.com.docker/pki'K8S entry container method
How to enter K8s with multiple containers in a pod
kubectl --namespace=kube-system exec -it kube-dns-1336009800-15b1h --container nginx -- sh
or
kubectl --namespace=kube-system exec -it kube-dns-1336009800-15b1h -c nginx -- sh
Note: --namespace is the namespace kube-dns is the name of the pod, and -c or -container is the name of one of the containers in the pod
Optional operation: Switch the Kubernetes running context to docker-desktop (the previous version of the context was docker-for-desktop)
kubectl config use-context docker-desktopVerify Kubernetes cluster status
kubectl cluster-info
kubectl get nodeskubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.5.1/aio/deploy/recommended.yamlor
kubectl apply -f kubernetes-dashboard.yamlCheck the status of kubernetes-dashboard application
kubectl get pod -n kubernetes-dashboardEnable API Server Access Agent
kubectl proxyAccess Kubernetes dashboard via the following URL
http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/
Authorize kube-system default service account
kubectl apply -f kube-system-default.yamlFor Mac environment
TOKEN= $( kubectl -n kube-system describe secret default | awk ' $1=="token:"{print $2} ' )
kubectl config set-credentials docker-desktop --token= " ${TOKEN} "
echo $TOKENFor Windows environment
$TOKEN = (( kubectl - n kube - system describe secret default | Select - String "token : ") - split " + ")[ 1 ]
kubectl config set-credentials docker-desktop --token=" ${TOKEN} "
echo $TOKEN 
Select a token
Enter the content output from the console above
Or select the Kubeconfig file, the path is as follows:
Mac: $HOME/.kube/config
Win: %UserProfile%.kubeconfig
Click to log in and enter Kubernetes Dashboard

Istio can be installed according to the documentation https://istio.io/docs/setup/getting-started/
For example, download Istio version 1.22.1 (other newer versions can be replaced by themselves), and execute the following command:
curl -L https://istio.io/downloadIstio | ISTIO_VERSION=1.22.1 sh -
cd istio-1.22.1
export PATH= $PWD /bin: $PATHNote: The Windows environment has not been rigorously tested.
On Windows, you can manually download the Istio installation package, or copy getLatestIstio.ps1 to the directory where you want to download Istio and execute - Note: Modified according to the installation script provided by the community
