ansible 增長本機/etc/hosts 下hostsname 與IP

 

 

---
- hosts: all
  vars:
     IP: "{{ ansible_eth0['ipv4']['address'] }}"
  tasks:
    - name: 將原有的hosts文件備份
      shell: mv /etc/hosts /etc/hosts_bak

    - name: 將ansible端的hosts複製到各自機器上
      copy: src=/root/hosts dest=/etc/ owner=root group=root mode=0644

    - name: 在新的hosts文件後面追加各自機器內網ip和hostname
      lineinfile: dest=/etc/hosts line="{{IP}}  {{ansible_hostname}}"
