boto3中不存在VPC Id

Question

我在AWS控制台中创建了一个VPC。基本上，我想创建一个python脚本，使用click指定一个VPC和一些其他CLI args。但是，当我创建一个安全组时，代码的一部分不断破坏。它抱怨VPC Id不存在时：

@click.command()
@click.option('--ami', help='What AWS AMI are you using?')
@click.option('--instancetype', help='AWS EC2 instance type')
@click.option('--vpc', help='VPC ID')
@click.option('--isweb',default=True,type=bool,help='Is this a web server')
@click.pass_context
def build(ctx,ami,instancetype,vpc,isweb):
    """ Will build out the EC2 instance """
    log.info("Building EC2...")
    log.info("Collecting Information....")
    log.info("AMI: " + ami)
    log.info("Instance Type: " + instancetype)
    log.info("VPC ID: " + vpc)
    log.info("Is this a web server: " + str(isweb))

    if isweb:
        log.info("Spinning up Web Server")
        log.info("Reading from Configuration file")

        config = configparser.RawConfigParser()
        config_path = os.getcwd() + '/config.txt'
        config.read(config_path)
        log.info("Reading from config file" + config_path)
        details_dict = dict(config.items('builder'))

        access_key = config.get('builder','aws_access_key_id')
        secret_key = config.get('builder','aws_secret_access_key')
        region = config.get('builder', 'region')
        ec2 = boto3.resource('ec2', aws_access_key_id=access_key,  aws_secret_access_key=secret_key, region_name=region)
        if ec2:
            log.info("AWS Session Created")
            sec_group = ec2.create_security_group(
                GroupName='webserver', Description='webserver', VpcId=vpc)
            sec_group.authorize_ingress(
                CidrIp='0.0.0.0/0',
                IpProtocol='tcp',
                FromPort=80,
                ToPort=80
                )

我传递的参数是vpc-它显然存在于控制台中。为什么不接受VPC id ???

Answer 1

我相信你的解决方案很简单。存储在vpc变量中的值是'vpc-id ....'。

删除单引号应该足够了。

或者，我会尝试使用客户端，看看它是否也发生在那里;

ec2 = boto3.client('ec2')

ec2.create_security_group(GroupName='webserver',Description='webserver',VpcId=vpc)

最后要检查的是区域，确保你的vpc正确。
