Alibaba Cloud Compute Services Guide
|

====================================

Introduction
|
|
````````````
|
|
|
|
Ansible contains several modules for controlling and managing Alibaba Cloud Compute Services (Alicloud). This guide
|
|
explains how to use the Alicloud Ansible modules together.
|
|
|
|
All Alicloud modules require ``footmark`` - install it on your control machine with ``pip install footmark``.
|
|
|
|
Cloud modules, including Alicloud modules, execute on your local machine (the control machine) with ``connection: local``, rather than on remote machines defined in your hosts.
|
|
|
|
Normally, you'll use the following pattern for plays that provision Alicloud resources::
|
|
|
|
- hosts: localhost
|
|
connection: local
|
|
vars:
|
|
- ...
|
|
tasks:
|
|
- ...
|
|
|
|
.. _alicloud_authentication:
|
|
|
|
Authentication
|
|
``````````````
|
|
|
|
You can specify your Alicloud authentication credentials (access key and secret key) by passing them as
|
|
environment variables or by storing them in a vars file.
|
|
|
|
To pass authentication credentials as environment variables::
|
|
|
|
export ALICLOUD_ACCESS_KEY='Alicloud123'
|
|
export ALICLOUD_SECRET_KEY='AlicloudSecret123'
|
|
|
|
To store authentication credentials in a vars_file, encrypt them with :ref:`Ansible Vault<vault>` to keep them secure, then list them::
|
|
|
|
---
|
|
alicloud_access_key: "--REMOVED--"
|
|
alicloud_secret_key: "--REMOVED--"
|
|
|
|
Note that if you store your credentials in a vars_file, you need to refer to them in each Alicloud module. For example::
|
|
|
|
- ali_instance:
|
|
alicloud_access_key: "{{alicloud_access_key}}"
|
|
alicloud_secret_key: "{{alicloud_secret_key}}"
|
|
image_id: "..."
|
|
|
|
.. _alicloud_provisioning:
|
|
|
|
Provisioning
|
|
````````````
|
|
|
|
Alicloud modules create Alicloud ECS instances, disks, virtual private clouds, virtual switches, security groups and other resources.
|
|
|
|
You can use the ``count`` parameter to control the number of resources you create or terminate. For example, if you want exactly 5 instances tagged ``NewECS``,
|
|
set the ``count`` of instances to 5 and the ``count_tag`` to ``NewECS``, as shown in the last task of the example playbook below.
|
|
If there are no instances with the tag ``NewECS``, the task creates 5 new instances. If there are 2 instances with that tag, the task
|
|
creates 3 more. If there are 8 instances with that tag, the task terminates 3 of those instances.
|
|
|
|
If you do not specify a ``count_tag``, the task creates the number of instances you specify in ``count`` with the ``instance_name`` you provide.

max_bandwidth_out: 50
|
|
vswitch_id: '{{ created_vsw.vswitch.id}}'
|
|
register: create_instance
|
|
|
|
In the example playbook above, data about the vpc, vswitch, group, and instances created by this playbook
|
|
are saved in the variables defined by the "register" keyword in each task.
|
|
|
|
Each Alicloud module offers a variety of parameter options. Not all options are demonstrated in the above example.
|
|
See each individual module for further details and examples.
