我正在尝试在 EKS Kubernetes 集群中设置AWS Xray Daemonset 。

问题是“xray-daemon” pod 无法以“CrashLoopBackOff”状态启动。

当我检查daemonse t pod 的日志时，显示以下错误：

Events:
Type Reason Age From Message
---- ------ ---- ---- -------
Normal Scheduled 20s default-scheduler Successfully assigned default/xray-daemon-wcnzt to ip-172-34-169-37.ap-south-1.compute.internal

重现步骤：

首先，我使用AWSXRayDaemonWriteAccess创建 IAM 服务账户

eksctl create iamserviceaccount \
    --name xray-daemon \
    --namespace default \
    --cluster eksdemo1 \
    --attach-policy-arn arn:aws:iam::aws:policy/AWSXRayDaemonWriteAccess \
    --approve \
    --override-existing-serviceaccounts

然后我尝试使用这个“xray-k8s-daemonset.yml”文件创建xray daemonset：

apiVersion: v1
kind: ServiceAccount
metadata:
  labels:
    app: xray-daemon
  name: xray-daemon
  namespace: default
  # Update IAM Role ARN created for X-Ray access
  annotations:

我确定角色 arn 是正确的（我在 AWS 控制台中检查了 arn）

该问题已通过使用“amazon/aws-xray-daemon:3.2.0”泊坞窗图像修复

“xray-k8s-daemonset.yml”中的pod 模板似乎不再适用于最新版本的“amazon/aws-xray-daemon”图像。

从映像版本3.3.0开始，有一些更改会破坏"xray-k8s-daemonset.yml"中的 xray daemonset部署。

因此，我在"xray-k8s-daemonset.yml" 中将图像"amazon/aws-xray-daemon"替换为"amazon/aws-xray-daemon:3.2.0 " 。

版本 3.2.0 工作正常，所以问题已修复

PS目前尚不清楚如何使 xray daemonset 与最新版本的“amazon/aws-xray-daemon”图像一起正常工作。

因此，仍然欢迎其他解决方案。
