Isito 部署

方法一：使用 istioctl 部署

# tar -zxvf istio-1.20.0-linux-amd64.tar.gz
# cd istio-1.20.0/bin/
# cp -rp istioctl /usr/bin/
# istioctl version
# istioctl profile list

# istioctl install --manifests=manifests/

# kubectl get pods -A

# Istio 默认启用自动 Sidecar 注入，为 default 命名空间打上标签 istio-injection=enabled。
# kubectl label namespace default istio-injection=enabled

配置更新

# istioctl upgrade --manifests=manifests/

卸载

# istioctl uninstall --purge

部署bookinfo示例

Bookinfo 应用分为四个单独的微服务：

Bookinfo 应用分为四个单独的微服务：

• productpage ：productpage 微服务会调用 details 和 reviews 两个微服务，用来生成页面。
• details ：这个微服务包含了书籍的信息。
• reviews ：这个微服务包含了书籍相关的评论。它还会调用 ratings 微服务。
• ratings ：ratings 微服务中包含了由书籍评价组成的评级信息。
• reviews 微服务有 3 个版本：

v1 版本不会调用 ratings 服务。
v2 版本会调用 ratings 服务，并使用 1 到 5 个黑色星形图标来显示评分信息。
v3 版本会调用 ratings 服务，并使用 1 到 5 个红色星形图标来显示评分信息。

# kubectl apply -f samples/bookinfo/platform/kube/bookinfo.yaml

要确认 Bookinfo 应用程序正在运行，请通过某个 pod 中的 curl 命令向其发送请求，例如来自 ratings：

# kubectl exec -it $(kubectl get pod -l app=ratings -o jsonpath='{.items[0].metadata.name}') -c ratings -- curl productpage:9080/productpage | grep -o "<title>.*</title>"

部署BookIno-Gateway

为应用程序定义入口网关
# kubectl apply -f /root/istio-1.20.0/samples/bookinfo/networking/bookinfo-gateway.yaml
# kubectl get gateway
# kubectl get svc -n istio-system istio-ingressgateway -o yaml 

访问测试服务

# curl <INGRESS-IP>:<INGRESS-PORT>/productpage
# curl 192.168.61.241:30526/productpage

方法二：使用 Istio Operator 部署

[root@cubestduio istio-1.20.0]# istioctl operator init
Installing operator controller in namespace: istio-operator using image: docker.io/istio/operator:1.20.0
Operator controller will watch namespaces: istio-system
✔ Istio operator installed
