attach volumes when launch instances

[Lingfeng Xiong]

It is better to add a UI option allowing attaching volumes when launch a new instance.
Some instances need to mount the attached volume at boot time (usually software start at boot time). Without this feature, it is required to launch a instance, attach volume then reboot it to make the software to use that volume.

Hello. Could you provide some more detail and use cases where this might be important. Thank you

Hi Ankur,
For example. I installed a git server VM. The operating system is installed on a ephemeral device, but of course the repository must stay in a persistent driver. In this case, I created an volume and attach the volume to the VM.
To make my git server automatically start, I created items in /etc/fstab to mount that persistent driver. Then even my VM reboots, the software can automatically start.

However, for some reason, I need to delete the instance and recreate it from image. In Horizon, I clicked on "Launch instance" button and pick that image, then create a instance. After creation, the instance starts, and I do not have any chance to mount the volume. Then my git server starts without volume mounted, and failed.

There are two ways to solve this problem: 1. allow mounting volumes in instance creation, or 2. allow put instance to "shutdown" status after creation.

Thank you for your quick reply. Will look into it. Hopefully can get more feedback on community on the BKM to implement this.

Sounds like this should be a BP rather than a bug?
