AWS Synthetics Canaryで実際に動くlambdaのArnを調べる

コンソールからだと見つけられないのでAWS CLIからjqで調べる。
フィルターは(それほど長いわけではないが) 別ファイルにして実行

$ aws synthetics describe-canaries | jq -f canary-lambda.txt`
[
  {
    "Name": "example-canary",
    "Function": "arn:aws:lambda:ap-northeast-1:xxxx:function:example-canary-xxxxx:1",
    "Role": "arn:aws:iam::xxxx:role/example-canary-ExecutionRole",
    "Code": {
      "SourceLocationArn": "arn:aws:lambda:ap-northeast-1:xxxx:layer:example-canary-xxxx:1",
      "Handler": "index.handler"
    },
    "RuntimeVersion": "syn-nodejs-puppeteer-3.4"
  }
]
