Ansible：将 yaml 文件从远程位置读取到变量中

Question

I want to read a yaml file on the remote location with Ansible and store the content to a variable which can be used my playbook during its runtime. Is this possible?

Answer 1

In respect to the comment of Zeitounator and the slurp _module examples, as well the set_fact _module

---
- hosts: test.example.com
  become: no
  gather_facts: no

  tasks:

  - name: Slurp remote YAML file
    slurp:
      src: "/home/{{ ansible_user }}/test.yaml"
    register: result

  - name: Set variable with result
    set_fact:
      SLURPED: "{{ result['content'] | b64decode }}"

  - name: Show variable
    debug:
      msg: "{{ SLURPED }}"

Answer 2

Run a command to output the content of the file (eg curl if you are fetching over http or cat if the file is on a local filesystem), then feed it to from_yaml :

- name: "Read yaml file"
  ansible.builtin.shell: "cat /path/to/file.yaml"
  register: result
  
- name: "Parse yaml into variable"
  set_fact:
    my_yaml: "{{ result.stdout | from_yaml }}"

You can then access the yaml via the my_yaml variable.
