我创建了一个开源脚本，可帮助您列出所有 AWS 实例。 https://github.com/Appnroll/aws-ec2-instances
这是脚本的一部分，它列出了一个配置文件的实例，将它们记录到 postgreSQL 数据库中，并使用jq 进行 json 解析：
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
