求教：使用AWS cli 如何創建系統盤為SSD的EC2 ？
uj5u.com熱心網友回復：
在block-device-mappings顯示指定使用gp2（ssd）的硬碟作為根設備（/dev/xvda）
aws ec2 run-instances --image-id=ami-146e2a7c --key-name=你的秘鑰 --instance-type=t2.micro --block-device-mappings="[{\"DeviceName\":\"/dev/xvda\",\"Ebs\":{\"DeleteOnTermination\":true,\"VolumeSize\":8,\"VolumeType\":\"gp2\"}}]"
不同的image根設備路徑不一樣
下面的命令查看image的根設備路徑，下面的RootDeviceName欄位
aws ec2 describe-images --image-ids ami-146e2a7c
