Alibaba Cloud (AliYun)#
The AliYun
datasource reads data from Alibaba Cloud ECS. Support is
present in cloud-init
since 0.7.9.
Metadata service#
The Alibaba Cloud metadata service is available at the well known URL
http://100.100.100.200/
. For more information see Alibaba Cloud ECS
on metadata.
Configuration#
The following configuration can be set for the datasource in system
configuration (in /etc/cloud/cloud.cfg
or
/etc/cloud/cloud.cfg.d/
).
An example configuration with the default values is provided below:
datasource:
AliYun:
metadata_urls: ["http://100.100.100.200"]
timeout: 50
max_wait: 120
Versions#
Like the EC2 metadata service, Alibaba Cloud’s metadata service provides
versioned data under specific paths. As of April 2018, there are only
2016-01-01
and latest
versions.
It is expected that the dated version will maintain a stable interface but
latest
may change content at a future date.
Cloud-init
uses the 2016-01-01
version.
You can list the versions available to your instance with:
$ curl http://100.100.100.200/
Example output:
2016-01-01
latest
