amazon-web-services - 如何在 Terraform 中为 stepfunction 启用 CloudWatch 日志记录和 X 射线？

问题描述

在 AWS 控制台中，我们可以轻松地为步进函数状态机启用 cloudwatch 日志记录和 X-ray，但我希望我的资源完全由 Terraform 管理，来自此页面：https ://registry.terraform.io/providers/hashicorp/aws/最新的/docs/resources/sfn_state_machine

目前看来 Terraform 不支持此功能（另请参阅：https ://github.com/hashicorp/terraform-provider-aws/issues/12192 ）

有谁知道是否有任何解决方法可以实现这一目标？我真的很希望能够同时启用来自 Terraform 的 cloudwatch 日志和 X 射线。我找不到太多这方面的信息。请问有人可以帮忙吗？非常感谢。

解决方案

更新：这是最近发布的功能3.27.0（2021 年 2 月 5 日）

对应文档链接：sfn_state_machine#logging

您可以包装用于在terraform null_resource中启用日志记录的命令，如链接问题Enabling Step Function Logging To CloudWatch #12192中所示，如下所示：

先决条件：

aws-cli/2.1.1

之前：


    {
    "stateMachineArn": "arn:aws:states:us-east-1:1234567890:stateMachine:mystatemachine",
    "name": "my-state-machine",
    "status": "ACTIVE",
    "definition": "{\n  \"Comment\": \"A Hello World example of the Amazon States Language using an AWS Lambda Function\",\n  \"StartAt\": \"HelloWorld\",\n  \"States\": {\n    \"HelloWorld\": {\n      \"Type\": \"Pass\",\n      \"End\": true\n    }\n  }\n}\n",
    "roleArn": "arn:aws:iam::1234567890:role/service-role/StepFunctions-MyStateMachine-role-a6146d54",
    "type": "STANDARD",
    "creationDate": 1611682259.919,
    "loggingConfiguration": {
        "level": "OFF",
        "includeExecutionData": false
    }
}

resource "aws_sfn_state_machine" "sfn_state_machine" {
  name     = "mystatemachine"
  role_arn = "arn:aws:iam::1234567890:role/service-role/StepFunctions-MyStateMachine-role-a6146d54"

  definition = <<EOF
{
  "Comment": "A Hello World example of the Amazon States Language using an AWS Lambda Function",
  "StartAt": "HelloWorld",
  "States": {
    "HelloWorld": {
      "Type": "Pass",
      "End": true
    }
  }
}
EOF
}

resource "aws_cloudwatch_log_group" "yada" {
  name = "/aws/vendedlogs/states/myloggroup"
}

resource "null_resource" "enable_step_function_logging" {
      triggers = {
    state_machine_arn  = aws_sfn_state_machine.sfn_state_machine.arn
    logs_params=<<PARAMS
    {
        "level":"ALL",
        "includeExecutionData":true,
        "destinations":[
            {
                "cloudWatchLogsLogGroup":{
                    "logGroupArn":"${aws_cloudwatch_log_group.yada.arn}:*"
                    }
                }
            ]
            }
    PARAMS
    }
  provisioner "local-exec" {
    command = <<EOT
set -euo pipefail

aws stepfunctions update-state-machine --state-machine-arn ${self.triggers.state_machine_arn}  --tracing-configuration enabled=true --logging-configuration='${self.triggers.logs_params}'

EOT
    # interpreter = ["bash"]
  }
}

之后：

{
    "stateMachineArn": "arn:aws:states:us-east-1:1234567890:stateMachine:mystatemachine",
    "name": "mystatemachine",
    "status": "ACTIVE",
    "definition": "{\n  \"Comment\": \"A Hello World example of the Amazon States Language using an AWS Lambda Function\",\n  \"StartAt\": \"HelloWorld\",\n  \"States\": {\n    \"HelloWorld\": {\n      \"Type\": \"Pass\",\n      \"End\": true\n    }\n  }\n}\n",
    "roleArn": "arn:aws:iam::1234567890:role/service-role/StepFunctions-MyStateMachine-role-a6146d54",
    "type": "STANDARD",
    "creationDate": 1611687676.151,
    "loggingConfiguration": {
        "level": "ALL",
        "includeExecutionData": true,
        "destinations": [
            {
                "cloudWatchLogsLogGroup": {
                    "logGroupArn": "arn:aws:logs:us-east-1:1234567890:log-group:/aws/vendedlogs/states/myloggroup:*"
                }
            }
        ]
    }
}
