EC2实例-在启动时附加临时驱动器

Question

我正在尝试使用boto在我的ec2实例上附加短暂的分区。

我用AWS工具试过了，并做了以下工作：

./ec2-run-instances ami-018c9568 --instance-type m2.4xlarge --availability-zone us-east-1a -n 1 -k my_keypair -g sg-11111111 -b "/dev/xvdb=ephemeral0" -b "/dev/xvdc=ephemeral1" -b "/dev/xvdd=ephemeral2" -b "/dev/xvde=ephemeral3"

当我用boto尝试它时，它不起作用：

mapping = BlockDeviceMapping() eph0 = BlockDeviceType() eph1 = BlockDeviceType() eph2 = BlockDeviceType() eph3 = BlockDeviceType() eph0.ephemeral_name = 'ephemeral0' eph1.ephemeral_name = 'ephemeral1' eph2.ephemeral_name = 'ephemeral2' eph3.ephemeral_name = 'ephemeral3' mapping['/dev/xvdb'] = eph0 mapping['/dev/xvdc'] = eph1 mapping['/dev/xvdd'] = eph2 mapping['/dev/xvde'] = eph3

Answer 1

这是正确的。我正在用一个短暂的实例类型进行实验(我以为它有两个)。希望它能帮助其他人。
