在Ansible中并行执行本地主机任务
在Ansible中并行执行本地主机任务
提问于 2022-09-19 11:33:12
我使用community.vmware.vmware_guest_powerstate集合来启动VM。
问题是一个VM所需的时间是2-5秒，这使得我想启动50个VM时效率很低.
有什么办法并行吗？
剧本：
- hosts: localhost
gather_facts: false
collections:
- community.vmware
vars:
certvalidate: "no"
server_url: "vc01.x.com"
username: "{{ lookup('ansible.builtin.env', 'API_USER', default=Undefined) }}"
password: "{{ lookup('ansible.builtin.env', 'API_PASS', default=Undefined) }}"
tasks:
- name: "setting state={{ requested_state }} in vcenter"
community.vmware.vmware_guest_powerstate:
username: "{{ lookup('ansible.builtin.env', 'API_USER', default=Undefined) }}"
password: "{{ lookup('ansible.builtin.env', 'API_PASS', default=Undefined) }}"
hostname: "{{ server_url }}"
datacenter: "DC1"
validate_certs: no
name: "{{ item }}"
state: "powered-on"
loop: "{{ hostlist }}"这是Ansible的输出：(每一行可以花费2-5秒.)

试试这个..。
- hosts: all
gather_facts: false
collections:
- community.vmware
vars:
certvalidate: "no"
server_url: "vc01.x.com"
username: "{{ lookup('ansible.builtin.env', 'API_USER', default=Undefined) }}"
password: "{{ lookup('ansible.builtin.env', 'API_PASS', default=Undefined) }}"
tasks:
- name: "setting state={{ requested_state }} in vcenter"
community.vmware.vmware_guest_powerstate:
username: "{{ username }}"
password: "{{ password }}"
hostname: "{{ server_url }}"
datacenter: "DC1"
validate_certs: no
name: "{{ inventory_hostname }}"
state: "powered-on"
delegate_to: localhost然后用主机列表作为库存并使用叉子运行它：
-i x1.com，x2.com，x3.com，.-叉子10 play.yml
