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实例上附加临时分区。

我已尝试使用AWS工具并且工作：

./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

这是对的。我正在尝试使用单个短暂的实例类型（我认为它有两个）。希望它能帮助其他人。
