RINGKASAN

Ini mungkin bukan bug tetapi hanya sesuatu yang saya dapatkan pada versi yang lebih lama tetapi dengan Ansible 2.3 RC1 jika saya memeriksa apakah variabel yang didaftarkan oleh modul (dengan klausa when) didefinisikan dan kemudian mendapatkan nilai sub dikt itu akan gagal di 2.3 sementara di 2.2 dan di bawah ini berfungsi dengan baik. Ini secara khusus terjadi ketika modul yang mendaftarkan variabel dilewati karena alasan apa pun dan kemudian tugas berikutnya memeriksa apakah variabel tersebut ditentukan dan kemudian mendapatkan sub kunci.

LANGKAH UNTUK REPRODUKSI

Contoh pedoman

---
- name: test
  hosts: localhost
  connection: local

  tasks:
  - name: module that won't run
    stat:
      path: /apps/tmp
    register: test
    when: False

  - name: debug of var
    debug:
      var: test

  - name: test with conditional
    debug:
      msg: A
    when: test is defined and test.stat.exists
