This helps get a 10,000 foot view of any EC2 instances running across all EC2 regions.
import boto3
#list regions
client = boto3.client('ec2')
regions = [region['RegionName'] for region in client.describe_regions()['Regions']]
print("Listing EC2 instances for each region....\n")
for i in regions:
print()
print(i)
print('---------')
Region = i
client = boto3.client('ec2', region_name=i)
response = client.describe_instances()
for reservation in response["Reservations"]:
for instance in reservation["Instances"]:
print(instance["InstanceId"])
Output looks like this:
~ $ python3.7 list_ec2_instances_in_all_regions.py Listing EC2 instances for each region.... eu-north-1 --------- ap-south-1 --------- eu-west-3 --------- eu-west-2 --------- eu-west-1 --------- ap-northeast-2 --------- ap-northeast-1 --------- sa-east-1 --------- ca-central-1 --------- ap-southeast-1 --------- ap-southeast-2 --------- eu-central-1 --------- us-east-1 --------- i-0336a147dc021b4d7 us-east-2 --------- us-west-1 --------- i-0dcccceea80e060e6 i-05b88a70f526dd8e8 us-west-2 --------- ~ $
