AnsibleのPlaybookを作成して実行していると実行前になんらかの変数を入力させたいことがある。
vars_prompt を使うと実現できる。
- name: Test
hosts: localhost
vars_prompt:
- name: "input_var"
prompt: "INPUT: "
confirm: no
private: no
default: "fish"
tasks:
- debug: msg="{{ input_var }}"試しにbeefを指定する。
.venv/bin/ansible-playbook playbook.yml
[WARNING]: Host file not found: /etc/ansible/hosts
[WARNING]: provided hosts list is empty, only localhost is available
INPUT: [fish]: beef

指定せずにENTERを押すとデフォルト値が使われる。
