Ansible Docker-为组中的每个主机编写

Question

# hosts
[webserver]
192.168.88.100
192.168.88.101
192.168.88.102

# playbook.yml
- hosts: localhost
  tasks:
  - docker_compose:
      docker_host: tcp://192.168.88.100:2375

Answer 1

我想你可以这样做：

# playbook.yml
- hosts: webserver
  tasks:
  - docker_compose:
      docker_host: "tcp://{{ ansible_eth0.ipv4.address }}:2375"
    delegate_to: localhost

{{ansible_eth0.ipv4.address}}允许您获取主机的ip地址。

delegate_to:localhost允许您将localhost指定为执行任务的主机。
