AWS X-RAY [错误] 发送分段批处理失败，原因是：NoCredentialProviders：链中没有有效的提供程序。 已弃用

Question

I'm using X-Ray Daemon with Fargate. Unfortunately in the logs of the daemon I see errors like:

[Error] Sending segment batch failed with: NoCredentialProviders: no valid providers in chain. Deprecated. For verbose messaging see aws.Config.CredentialsChainVerboseErrors Warn] Delaying sending of additional batches by 0 seconds

AWS X-Ray works with IAM: permission: AWSXrayFullAccess

I already checked:

• https://github.com/aws-samples/aws-xray-fargate
• https://docs.amazonaws.cn/en_us/xray/latest/devguide/xray-guide.pdf

Answer 1

You should check you role permissions role, I used the same for execution & taskRoleArn. my role contained these policies

• arn:aws:iam::aws:policy/AmazonEC2ContainerRegistryReadOnly
• arn:aws:iam::aws:policy/CloudWatchAgentServerPolicy
• arn:aws:iam::aws:policy/service-role/AmazonECSTaskExecutionRolePolicy
• arn:aws:iam::aws:policy/AWSXRayFullAccess

and also check trust relationships for role. my used:

• ecs-tasks.amazonaws.com
• ecs.amazonaws.com
• c2.amazonaws.com

Answer 2

I got this error when my version of the x-ray deamon was old.

Follow this as guidance to update your x-ray deamon if it is running on ECS:

https://docs.aws.amazon.com/xray/latest/devguide/xray-daemon-ecs.html

Answer 3

XRay daemon is missing credentials needed to authenticate with XRay server. You can pass credentials to XRay daemon in several ways, but the most common are:

1. through environment variables AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
2. through ~/.aws/credentials file (see https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-files.html )

I'm guessing option 1 will be easier with fargate.

Of course you need to generate the key in IAM, see: https://docs.aws.amazon.com/powershell/latest/userguide/pstools-appendix-sign-up.html

The user you'll create the access key for will need to have permissions to use XRay (AWSXrayFullAccess should do).
