启动 Loki pod 时出现授权错误

Question

今天早上我发现 Loki 在 EKS 集群中停止工作

在 loki pod 日志中，我看到以下内容：

level=error ts=2022-04-07T10:44:43.298418416Z caller=table_manager.go:233 msg="error syncing tables" err="WebIdentityErr: failed to retrieve credentials\ncaused by: RequestError: send request failed\ncaused by: Post \"https://sts.us-east-2.amazonaws.com/\": dial tcp XXX.XXX.XXX.XXX:443: i/o timeout"

ServiceAccount 存在且未更改
IAM 角色存在且未更改
与 Loki 和 prometheus 相关的仪表板停止工作（prometheus 与 thanos 一起工作）

示例值文件 - 通过 flux 进行部署：

Answer 1

因此，问题出在 AWS 的 IAM 角色中。我更改了设置并添加了

                "arn:aws:dynamodb:us-east-2:${data.aws_caller_identity.current.account_id}:table/loki_/index/*",
            "arn:aws:dynamodb:us-east-2:${data.aws_caller_identity.current.account_id}:table/loki_",
            "arn:aws:s3:::${var.aws_s3_loki_storage}/*",
            "arn:aws:s3:::${var.aws_s3_loki_storage}"
