下面是我的脚本，基于这篇文章和其他地方的各种技巧。脚本比长命令行更容易理解(至少对我来说)。

脚本假设凭据概要文件存储在文件~/中。Aws /凭证看起来像这样:

[default]
aws_access_key_id = foobar
aws_secret_access_key = foobar

[work]
aws_access_key_id = foobar
aws_secret_access_key = foobar

脚本:

您可以使用cli的云资源枚举工具(跨地区、跨账号扫描)- https://github.com/scopely-devops/skew

经过简单配置后，您可以使用以下代码列出所有美国AWS区域中的所有实例(假设123456789012是您的AWS帐号)。

from skew import scan

arn = scan('arn:aws:ec2:us-*:123456789012:instance/*')
for resource in arn:
    print(resource.data)

我认为目前在AWS GUI中无法做到这一点。但是这里有一种方法可以用AWS CLI列出所有地区的所有实例:

for region in `aws ec2 describe-regions --region us-east-1 --output text | cut -f4`
do
     echo -e "\nListing Instances in region:'$region'..."
     aws ec2 describe-instances --region $region
done

从这里开始(如果你想看完整的讨论)

另外，如果你得到一个

必须指定一个区域。您也可以通过运行“aws configure”来配置您的区域。

你可以通过aws配置set region us-east-1来实现，谢谢@Sabuncu的评论。

更新

现在(2019年)cut命令应该应用在第4个字段:cut -f4

我创建了一个开源脚本，可以帮助您列出所有AWS实例。https://github.com/Appnroll/aws-ec2-instances

这是脚本的一部分，列出了一个配置文件的实例，并使用jq进行json解析，将它们记录到postgreSQL数据库中:

DATABASE="aws_instances"
TABLE_NAME="aws_ec2"
SAVED_FIELDS="state, name, type, instance_id, public_ip, launch_time, region, profile, publicdnsname"
# collects the regions to display them in the end of script
REGIONS_WITH_INSTANCES=""

for region in `aws ec2 describe-regions --output text | cut -f3`
do
   # this mappping depends on describe-instances command output
   INSTANCE_ATTRIBUTES="{
        state: .State.Name,
        name: .KeyName, type: .InstanceType,
        instance_id: .InstanceId,
        public_ip: .NetworkInterfaces[0].Association.PublicIp,
        launch_time: .LaunchTime,
        \"region\": \"$region\",
        \"profile\": \"$AWS_PROFILE\",
        publicdnsname: .PublicDnsName
   }"

   echo -e "\nListing AWS EC2 Instances in region:'$region'..."
   JSON=".Reservations[] | ( .Instances[] | $INSTANCE_ATTRIBUTES)"
   INSTANCE_JSON=$(aws ec2 describe-instances --region $region)

   if echo $INSTANCE_JSON | jq empty; then
      # "Parsed JSON successfully and got something other than false/null"
      OUT="$(echo $INSTANCE_JSON | jq $JSON)"

      # check if empty
      if [[ ! -z "$OUT" ]] then
        for row in $(echo "${OUT}" | jq -c "." ); do
          psql -c "INSERT INTO $TABLE_NAME($SAVED_FIELDS) SELECT $SAVED_FIELDS from json_populate_record(NULL::$TABLE_NAME, '${row}') ON CONFLICT (instance_id)
            DO UPDATE
            SET state = EXCLUDED.state,
            name = EXCLUDED.name,
            type = EXCLUDED.type,
            launch_time = EXCLUDED.launch_time,
            public_ip = EXCLUDED.public_ip,
            profile = EXCLUDED.profile,
            region = EXCLUDED.region,
            publicdnsname = EXCLUDED.publicdnsname
            " -d $DATABASE
        done

        REGIONS_WITH_INSTANCES+="\n$region"
      else
        echo "No instances"
      fi
   else
        echo "Failed to parse JSON, or got false/null"
   fi
done

来自VPC Dashboard:

首先进入“VPC面板” 然后找到正在运行的实例并展开“查看所有区域”。在这里你可以找到所有区域的运行实例:

EC2全球视角:

您还可以使用AWS EC2全局视图来查看资源摘要 和每个区域的资源计数。
