是否有可能从OpenStack的图像创建AMI？ [英] Is it possible to create an ami from an openstack image?

问题描述

我要创建从一个正在运行的实例在OpenStack的图片

I'm creating an image from a running instance in OpenStack

nova image-create <server-name>

和我只是想知道，可这个图片被上传到EC2？或者我需要从它创建AMI？

and i'm just wondering,can this image be uploaded to ec2? Or do i need to create an ami from it?

有人能指导我如何去吗？

Can someone guide me on how to go about this?

推荐答案

一目了然，OpenStack的影像服务能够存储数字图像类型的：

glance, the openstack image service is capable of storing a number of image types:

Raw
Machine (kernel/ramdisk outside of image, a.k.a. AMI)
VHD (Hyper-V)
VDI (VirtualBox)
qcow2 (Qemu/KVM)
VMDK (VMWare)
OVF (VMWare, others)

参考： http://www.openstack.org/projects/image-service/

所以基本上。您可以上传的AMI直接OpenStack的。

So basically. You can upload AMIs to openstack directly.

例如：

KERNEL_ID=`glance image-create --name="tty-linux-kernel" --disk-format=aki --container-format=aki < ttylinux-uec-amd64-12.1_2.6.35-22_1-vmlinuz | awk '/ id / { print $4 }'`
INITRD_ID=`glance image-create --name="tty-linux-ramdisk" --disk-format=ari --container-format=ari < ttylinux-uec-amd64-12.1_2.6.35-22_1-loader | awk '/ id / { print $4 }'`
glance image-create --name="tty-linux" --disk-format=ami --container-format=ami --property kernel_id=${KERNEL_ID} --property ramdisk_id=${INITRD_ID} < ttylinux-uec-amd64-12.1_2.6.35-22_1.img

当执行图像创建针对运行实例

When performing an image-create against a running instance

图片只能从运行中的实例，如果计算配置为使用qcow2>图像，这是默认设置创建的。您可以通过添加以下行nova.conf明确允许使用qcow2图像>的：

Images can only be created from running instances if Compute is configured to use qcow2 > images, which is the default setting. You can explicitly enable the use of qcow2 images > by adding the following line to nova.conf:

不过，假设您被配置为这样，是的，它会在AMI格式输出。

But assuming you are configured as such, yes it will output in AMI format.
