Enable Kubernetes on Docker Desktop for Mac

Config registry mirror for Docker daemon with https://docker.mirrors.ustc.edu.cn only if in China

Optional: config the CPU and memory for Kubernetes, 4GB RAM or more is suggested.

Preload Kubernetes images form Alibaba Cloud Registry Service, NOTE: you can modify the images.properties for your own images

./load_images.sh

Enable Kubernetes in Docker for Mac, and wait a while for Kubernetes is running

Enable Kubernetes on Docker Desktop for Windows

Config registry mirror for Docker daemon with https://docker.mirrors.ustc.edu.cn only if in China

Optional: config the CPU and memory for Kubernetes, 4GB RAM or more is suggested.

Preload Kubernetes images form Alibaba Cloud Registry Service, NOTE: you can modify the images.properties for your own images

In Bash shell

./load_images.sh

or in PowerShell of Windows

 .\load_images.ps1

NOTE: if you failed to start PowerShell scripts for security policy, please execute Set-ExecutionPolicy RemoteSigned command in PowerShell with "Run as administrator" option.

Enable Kubernetes in Docker for Windows, and wait a while for Kubernetes is running

Config Kubernetes

Optional: switch the context to docker-for-desktop (under docker ce 18.09, the conext is docker-desktop)

kubectl config use-context docker-for-desktop

Verify Kubernetes installation

kubectl cluster-info
kubectl get nodes

Deploy Kubernetes dashboard

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml

or

kubectl create -f kubernetes-dashboard.yaml

Start proxy for API server

kubectl proxy

Access Kubernetes dashboard

http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/overview?namespace=default

Config kubeconfig (Or skip)

For Mac

TOKEN=$(kubectl -n kube-system describe secret default| awk '$1=="token:"{print $2}')
kubectl config set-credentials docker-for-desktop --token="${TOKEN}"

For Windows

$TOKEN=((kubectl -n kube-system describe secret default | Select-String "token:") -split " +")[1]
kubectl config set-credentials docker-for-desktop --token="${TOKEN}"

Choose kubeconfig file (Optional)

Choose kubeconfig file, Path：

Win: %UserProfile%\.kube\config
Mac: $HOME/.kube/config

brew install kubernetes-helm

# Install Tiller into your Kubernetes cluster
helm init --upgrade -i registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.14.3 --skip-refresh

# update charts repo (Optional)
helm repo update

For Windows

# Use Chocolatey on Windows
# NOTE: please ensure you can access googleapis
choco install kubernetes-helm

# Install Tiller into your Kubernetes cluster
helm init --upgrade -i registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.14.1 --skip-refresh

# update charts repo (Optional)
helm repo update

Install Istio

More details can be found in https://istio.io/docs/setup/kubernetes/

Download Istio 1.3.3 and install CLI

curl -L https://git.io/getLatestIstio | ISTIO_VERSION=1.3.3 sh -
cd istio-1.3.3/
export PATH=$PWD/bin:$PATH

Install Istio with Helm chart

# Install the istio-init chart to bootstrap all the Istio’s CRDs
helm install install/kubernetes/helm/istio-init --name istio-init --namespace istio-system

# Verify that all Istio CRDs were committed to the Kubernetes api-server
kubectl get crds | grep 'istio.io\|certmanager.k8s.io' | wc -l

# Install the istio chart
helm install install/kubernetes/helm/istio --name istio --namespace istio-system

Check status of istio release

helm status istio

Enable automatic sidecar injection for default namespace

kubectl label namespace default istio-injection=enabled
kubectl get namespace -L istio-injection

Install Book Info sample
