当工作负载以 User ID (UID) 1337
运行时,会出现此消息。应用程序的 Pod 不应该以
User ID (UID) 1337
运行,因为 istio-proxy 容器默认以 UID 1337
运行。
当使用相同的 UID 运行您的容器应用时,将导致它的 iptables
配置冲突。

User ID (UID) 1337
保留用于 Sidecar Proxy。

示例
探讨设置为 securityContext.runAsUser
的 Deployment
如何使用 UID 1337
在 Pod 级别或容器级别运行:
{{< text yaml >}} apiVersion: apps/v1 kind: Deployment metadata: name: deploy-con-sec-uid labels: app: helloworld version: v1 spec: replicas: 1 selector: matchLabels: app: helloworld version: v1 template: metadata: labels: app: helloworld version: v1 spec: securityContext: runAsUser: 1337 containers: - name: helloworld image: docker.io/istio/examples-helloworld-v1 securityContext: runAsUser: 1337 resources: requests: cpu: "100m" imagePullPolicy: IfNotPresent #Always ports: - containerPort: 5000 {{< /text >}}
如何修复
由于 User ID (UID) 1337
是为 Sidecar 代理保留的,所以您可以为您的工作负载使用除了
1337
以外的 User ID (UID),例如 1338
。
{{< text yaml >}} apiVersion: apps/v1 kind: Deployment metadata: name: deploy-con-sec-uid labels: app: helloworld version: v1 spec: replicas: 1 selector: matchLabels: app: helloworld version: v1 template: metadata: labels: app: helloworld version: v1 spec: securityContext: runAsUser: 1338 containers: - name: helloworld image: docker.io/istio/examples-helloworld-v1 securityContext: runAsUser: 1338 resources: requests: cpu: "100m" imagePullPolicy: IfNotPresent #Always ports: - containerPort: 5000 {{< /text >}}
