~> Note: Images can become deprecated after a while; run
`aliyun ecs DescribeImages` to find one that exists.

~> Note: Since WinRM is closed by default in the system image. If you are
planning to use Windows as the base image, you need enable it by userdata in
order to connect to the instance, check
[alicloud_windows.json](https://github.com/hashicorp/packer/tree/master/builder/alicloud/examples/basic/alicloud_windows.json)
and
[winrm_enable_userdata.ps1](https://github.com/hashicorp/packer/tree/master/builder/alicloud/examples/basic/winrm_enable_userdata.ps1)
for details.

See the
[examples/alicloud](https://github.com/hashicorp/packer/tree/master/builder/alicloud/examples)
folder in the packer project for more examples.
