Question

我一直在学习terraform，并且一直在使用仪表板。

我有以下文件会生成一个仪表板。

resource "aws_cloudwatch_dashboard" "main" {
  dashboard_name = "sample_dashboard"
  dashboard_body = <<EOF
{
  "widgets": [
    ${templatefile("${path.module}/cpu.tmpl", { ids = aws_instance.web[*].id })},
    ${templatefile("${path.module}/network.tmpl", { ids = aws_instance.web[*].id })}
  ]
}
EOF
}

这是cpu模板文件。

{
  "type": "metric",
  "x": 0,
  "y": 0,
  "width": 12,
  "height": 6,
  "properties": {
    "metrics": ${jsonencode([for id in ids : ["AWS/EC2","CPUUtilization","InstanceId", "${id}"]])},
    "period": 300,
    "stat": "Average",
    "region": "us-east-1",
    "title": "EC2 Instance CPU"
  }
}

这里有网络模板文件。

{
  "type": "metric",
  "x": 12,
  "y": 0,
  "width": 12,
  "height": 6,
  "properties": {
    "metrics": ${jsonencode([for id in ids :
                  ["AWS/EC2", "NetworkIn", "InstanceId", "${id}"]
                ])},
    "period": 300,
    "stat": "Average",
    "region": "us-east-1",
    "title": "EC2 Instance Network"
  }
}

一切正常，我得到以下信息中心。

我遇到的问题是尝试在for循环中添加另一个指标时出现错误。

{
  "type": "metric",
  "x": 12,
  "y": 0,
  "width": 12,
  "height": 6,
  "properties": {
    "metrics": ${jsonencode([for id in ids :
                  ["AWS/EC2", "NetworkIn", "InstanceId", "${id}"],
                  ["AWS/EC2", "NetworkOut", "InstanceId", "${id}"]
                ])},
    "period": 300,
    "stat": "Average",
    "region": "us-east-1",
    "title": "EC2 Instance Network"
  }
}

我收到以下错误消息。

对函数“ templatefile”的调用失败：./network.tmpl:9,70-71：无效的“ for”表达式； “ for”结束后的多余字符表达..

一如既往，在此先感谢您的帮助。

解决该问题的一种方法是concat您的指标：
