AWS 无法连接到终端节点 URL

Question

即使我在我的脚本和 .aws/config 文件中将区域更改为 eu-west-1b，它仍然给我这个错误，我的实例一直在 eu-west-1b 中启动，所以不确定为什么我收到此错误。

#!/usr/bin/env python3
import sys
import boto3
import time
ec2 = boto3.resource('ec2', region_name = 'eu-west-1b')
s3 = boto3.resource('s3')
keyname = 'key1.pem'
s3_resource = boto3.resource('s3')
user_data = '''#!/bin/bash
yum update -y
yum install httpd -y
systemctl enable httpd
systemctl start httpd'''

try:
        res = Resp = s3.create_bucket(ACL='private',Bucket='buket2',CreateBucketConfiguration={'LocationConstraint': 'eu-west-1b'})
        print (res)

try:
        s3_resource.Bucket('buket2').upload_file('image.jpg', 'image.jpg', ExtraArgs={'ACL': 'public-read'})


try:
        gg = ec2.create_security_group(GroupName='Server', Description = 'Serv1', VpcId='vpc-f3fs4095')

        print (gg)
except Exception as error:
    print (error)

instance = ec2.create_instances(
 ImageId='ami-03odd1b743b23e5d2',
 MinCount=1,
 MaxCount=1,
 InstanceType='t2.nano',
 KeyName = 'key1.pem',
 UserData = user_data, 
 SecurityGroupIds=[sg.group_id] 
)


from datetime import datetime, timedelta
time.sleep(600)
client = boto3.client('cloudwatch', region_name='eu-west-1b')
response = client.get_metric_statistics(
            Namespace='AWS/EC2',
            MetricName='CPUUtilization',
            Dimensions=[
                {
                'Name': 'AMIID',
                'Value': 'ami-03odd1b743b23e5d2'
                },
            ],
            StartTime=datetime.now() - timedelta(seconds=600),
            EndTime=datetime.now(),
            Period=300,
            Statistics=[
                'Average',
            ],
            Unit='Percent'
        )
print(response)

response = sg.authorize_ingress(
    IpPermissions=[
        {
            "FromPort": 22,
            "ToPort": 22,
            "IpProtocol": "tcp",
            "IpRanges": [
                {"CidrIp": "0.0.0.0/0", "Description": "Server"},
            ],
        },
        {
            "FromPort": 80,
            "ToPort": 80,
            "IpProtocol": "tcp",
            "IpRanges": [
                {"CidrIp": "0.0.0.0/0", "Description": "Server1"},
            ],
        },
    ],
)

我收到了一条很长的错误消息，但只会包含重要的部分，因为其中大部分只是指向文件，除非您也希望我包含。

Answer 1

区域名称是eu-west-1。

b 标识一个可用区：eu-west-1b

在 boto3 中创建 Resource 或 Client 时，使用不带 AZ 标识符的 Region：

ec2 = boto3.resource('ec2', region_name = 'eu-west-1')

要在特定可用区中启动 Amazon EC2 实例，请在 create_instances() 或 run_instances() 中指定：

Placement={'AvailabilityZone': 'eu-west-1b'}

或：

SubnetId = 'YOUR SUBNET ID'

“如果未指定，将根据区域的负载平衡条件自动为您选择可用区。”
