This article is designed to help understand istio want to install and run bookinfo example students QuickStart
Pre-preparation
Installation k8s and helm
1, k8s installation
Modify the hostname
hostnamectl set-hostname k8s-master hostnamectl set-hostname k8s-node
Ali Cloud environment configure yum source gpg and check the configuration
docker-ce under /etc/yum.repos.d directory wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo Kubernetes under /etc/yum.repos.d directory vim kubenetes .repo [Kubernetes] name = Kubernetes Repo BaseURL = HTTPS: //mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/ gpgcheck. 1 = gpgkey = HTTPS: //mirrors.aliyun.com/kubernetes/ yum / DOC / yum-key.gpg Enabled. 1 =
gpg check the configuration
wget https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg wget https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg rpm --import rpm-package-key.gpg rpm --import yum-key.gpg
According to the official installation kubeadm example (installing version 1.15.4 k8s)
yum -y install Rocker-ce-omelet-kubeadm 1.15.4 1.15.4 1.15.4-kubectl
Set an example of environmental parameters in accordance with official
https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/install-kubeadm/
https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/create-cluster-kubeadm/
kubeadm init run with Ali cloud images
The init kubeadm \ image-repository registryaliyuncscomgooglecontainers \ pod-network-cidr = 1024400/16 And
Wherein 10.244.0.0/16 is flannel network parameters will be added
2, helm installation
1. Download and install
wget https://get.helm.sh/helm-v2.14.3-linux-amd64.tar.gz tar -zxf helm-v2.14.3-linux-amd64.tar.gz cd linux-amd64 chmod +x helm mv helm /usr/local/bin
2. Make sure you have a cluster administrator defines the role of the service account for the Tiller
kubectl apply -f https://raw.githubusercontent.com/istio/istio/release-1.3/install/kubernetes/helm/helm-service-account.yaml
3. Ali mirror installation tiller, while the repo changed to Microsoft's helm repo
helm init --upgrade -i registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.14.3 --stable-repo-url http://mirror.azure.cn/kubernetes/charts/ --service-account=tiller
Istio installation
1. Download the installation package
Reference Address: https://istio.io/docs/setup/#downloading-the-release
curl -L https://git.io/getLatestIstio | ISTIO_VERSION=1.3.1 sh - cd istio-1.3.1 export PATH=$PWD/bin:$PATH
2. Installation istio with helm install and Helm Tiller
Reference Address: https://istio.io/docs/setup/install/helm/
Use kubectl apply to install all Istio custom resource definition (CRD), and wait a few seconds for submission to the CRD in Kubernetes API server:
helm install install/kubernetes/helm/istio-init --name istio-init --namespace istio-system --set gateways.istio-ingressgateway.type=NodePort
Use the following command to verify that all 23 Istio CRD are submitted to Kubernetes api server:
kubectl get crds | grep 'istio.io' | wc -l
Select a profile, and then install the files you selected corresponds istio chart:
helm install install/kubernetes/helm/istio --name istio --namespace istio-system \ --values install/kubernetes/helm/istio/values-istio-demo.yaml \ --set gateways.istio-ingressgateway.type=NodePort
3. Run bookinfo example
Reference Address: https://istio.io/docs/examples/bookinfo/
kubectl label namespace default istio-injection=enabled
kubectl apply -f samples/bookinfo/platform/kube/bookinfo.yaml
kubectl get pods
kubectl apply -f samples/bookinfo/networking/bookinfo-gateway.yaml
export INGRESS_PORT=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.spec.ports[?(@.name=="http2")].nodePort}')
export SECURE_INGRESS_PORT=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.spec.ports[?(@.name=="https")].nodePort}')
export INGRESS_HOST=<k8s-node ip>
export GATEWAY_URL=$INGRESS_HOST:$INGRESS_PORT
Browser to access HTTP: // $ {} GATEWAY_URL / productpage
