Enable Kubernetes in Docker for Windows, and wait a while for Kubernetes is running ![k8s](images/k8s_win.png) ### Config Kubernetes Optional: switch the context to `docker-for-desktop` (under docker ce 18.09, the conext is `docker-desktop`) ```shell kubectl config use-context docker-for-desktop ``` Verify Kubernetes installation ```shell kubectl cluster-info kubectl get nodes ``` Deploy Kubernetes dashboard ```shell kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml ``` or ```shell kubectl create -f kubernetes-dashboard.yaml ``` Start proxy for API server ```shell 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 ```bash TOKEN=$(kubectl -n kube-system describe secret default| awk '$1=="token:"{print $2}') kubectl config set-credentials docker-for-desktop --token="${TOKEN}" ``` For Windows ```cmd $TOKEN=((kubectl -n kube-system describe secret default | Select-String "token:") -split " +")[1] kubectl config set-credentials docker-for-desktop --token="${TOKEN}" ``` #### Choose kubeconfig file (Optional) ![resource](images/k8s_credentials.png) Choose kubeconfig file, Path： ``` Win: %UserProfile%\.kube\config Mac: $HOME/.kube/config ``` Click login, go to Kubernetes Dashboard ### Install Helm Install helm following the instruction on https://github.com/helm/helm/blob/master/docs/install.md #### For Mac OS ```shell # Use homebrew on Mac brew install kubernetes-helm # Install Tiller into your Kubernetes cluster helm init --upgrade -i registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.15.1 --skip-refresh # update charts repo (Optional) helm repo update ``` #### For Windows ```shell # Use Chocolatey on Windows # NOTE: please ensure you can access googleapis choco install kubernetes-helm # Install Tiller into your Kubernetes cluster helm init --upgrade -i registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.15.1 --skip-refresh # update charts repo (Optional) helm repo update ``` ### Install Istio More details can be found in https://istio.io/docs/setup/kubernetes/ Download Istio 1.2.4 and install CLI ```bash curl -L https://git.io/getLatestIstio | ISTIO_VERSION=1.2.4 sh - cd istio-1.2.4/ export PATH=$PWD/bin:$PATH ``` Install Istio with Helm chart ```shell # Install the istio-init chart to bootstrap all the Istio’s CRDs helm install install/kubernetes/helm/istio-init --name istio-init --namespace istio-system # Verify that all Istio CRDs were committed to the Kubernetes api-server kubectl get crds | grep 'istio.io\|certmanager.k8s.io' | wc -l # Install the istio chart helm install install/kubernetes/helm/istio --name istio --namespace istio-system ``` Check status of istio release ```shell helm status istio ``` Enable automatic sidecar injection for ```default``` namespace ```shell kubectl label namespace default istio-injection=enabled kubectl get namespace -L istio-injection ``` Install Book Info sample ```shell kubectl apply -f samples/bookinfo/platform/kube/bookinfo.yaml kubectl apply -f samples/bookinfo/networking/bookinfo-gateway.yaml Confirm application is running ​```bash export GATEWAY_URL=localhost:80 curl -o /dev/null -s -w "%{http_code}\n" http://${GATEWAY_URL}/productpage ``` Delete Istio ```shell helm del --purge istio kubectl delete -f install/kubernetes/helm/istio/templates/crds.yaml -n istio-system ```
