以下是使用Ansible调用OpenStack API批量部署云主机的步骤:
1. 安装OpenStack SDK
在Ansible控制节点上安装OpenStack SDK,可以使用pip命令进行安装:
```
pip install openstacksdk
```
2. 配置OpenStack连接信息
在Ansible控制节点上创建一个OpenStack配置文件,例如openstack.ini,其中包含OpenStack连接信息:
```
[auth]
auth_url = http://<OpenStack IP>:5000/v3
username = <OpenStack用户名>
password = <OpenStack密码>
project_name = <OpenStack项目名称>
user_domain_name = Default
project_domain_name = Default
```
3. 创建Ansible Playbook
创建一个Ansible Playbook,例如deploy_instances.yaml,用于批量部署云主机。以下是一个示例Playbook:
```
---
- name: Deploy instances
hosts: localhost
gather_facts: false
vars:
image_name: "Ubuntu 18.04"
flavor_name: "m1.small"
network_name: "private"
security_group_name: "default"
keypair_name: "mykey"
count: 3
name_prefix: "test"
tasks:
- name: Authenticate with OpenStack
os_auth:
cloud: default
- name: Get image ID
os_image_info:
name: "{{ image_name }}"
register: image
- name: Get flavor ID
os_flavor_info:
name: "{{ flavor_name }}"
register: flavor
- name: Get network ID
os_network_info:
name: "{{ network_name }}"
register: network
- name: Get security group ID
os_security_group_info:
name: "{{ security_group_name }}"
register: security_group
- name: Create instances
os_server:
name: "{{ name_prefix }}-{{ item }}"
image: "{{ image.results[0].id }}"
flavor: "{{ flavor.results[0].id }}"
network: "{{ network.results[0].id }}"
security_groups: "{{ security_group.results[0].id }}"
key_name: "{{ keypair_name }}"
with_sequence: count
```
在Playbook中,我们首先使用os_auth模块进行OpenStack身份验证。然后,我们使用os_image_info、os_flavor_info、os_network_info和os_security_group_info模块获取所需资源的ID。最后,我们使用os_server模块创建指定数量的云实例,并使用with_sequence循环迭代。
4. 运行Ansible Playbook
使用ansible-playbook命令运行Playbook:
```
ansible-playbook deploy_instances.yaml -i openstack.ini
```
这将使用openstack.ini文件中的连接信息连接到OpenStack,并创建指定数量的云实例。
注意:在运行Playbook之前,请确保已经创建了相应的OpenStack密钥对,以便可以在创建云实例时使用。
