ansible-playbook -- 变量传递

ansible-playbook -- 变量传递

variable变量：在/etc/ansible/hosts添加以下行：
[dbsrvs]
101.xxx.xxx.102 ansible_ssh_user=root http_port=8888
101.xxx.xxx.101ansible_ssh_user=root http_port=9999

编写一个yaml文件：
- hosts: dbsrvs
  remote_user: root
# 定义playbook变量
  vars:
  - pbvars: playbook variables
  tasks:
# 此处是命令行变量
  - name: command line variables
    copy: content={{ cmdvar }} dest=/tmp/cmd.var
# 此处是playbook变量
  - name: playbook variables
    copy: content={{ pbvars }} dest=/tmp/pb.var
# 此处是host inventory变量
  - name: host inventory variables
    copy: content={{ http_port }} dest=/tmp/hi.var

执行:ansible-playbook -e cmdvar=command_line_variable_testing   vars.yaml
 

执行结果，在两台受控主机上写入了传入命令行参数、host inventory参数以及playbook传递的变量：
