I am trying to list the instances on tag values of different tag keys
For eg> one tag key - Environment, other tag key - Role.
My code is given below :
import argparse
import boto3
AWS_ACCESS_KEY_ID = '<Access Key>'
AWS_SECRET_ACCESS_KEY = '<Secret Key>'
def get_ec2_instances(Env,Role):
ec2 = boto3.client("ec2", region)
reservations = ec2.describe_instances(Filters={"tag:environment" : Env, "tag:role" : Role})
for reservation in reservations["Reservations"] :
for instance in reservation["Instances"]:
print "%s" % (instance.tags['Name'])
if __name__ == '__main__':
regions = ['us-east-1','us-west-1','us-west-2','eu-west-1','sa-east-1',
'ap-southeast-1','ap-southeast-2','ap-northeast-1']
parser = argparse.ArgumentParser()
parser.add_argument('Env', default="environment", help='value for tag:environment');
parser.add_argument('Role', default="role", help='value for tag:role');
args = parser.parse_args()
for region in regions: get_ec2_instances(args.Env, args.Role)
After running this script : python script.py arg1 arg2
I am getting following error
