簡單劇本中的Ansible YAML語法錯誤

Question

我有我的第一本劇本，它失敗了。我認爲這是一個語法錯誤，但由於我不是一個編碼器，我不知道爲什麼YAML失敗？它與間距有關嗎？

以下是我有：

--- 
- name: Update all packages to the latest version 
    become: true 
    apt: 
     update_cache: yes  
     upgrade: dist 

- name: Remove useless packages from the cache 
    apt: 
     autoclean: yes 

- name: Remove dependencies that are no longer required 
    apt: 
     autoremove: yes 

ERROR! Syntax Error while loading YAML. 


The error appears to have been in '/home/pi/playbooks/update-apt.yml': line 3, column 11, but may 
be elsewhere in the file depending on the exact syntax problem. 

The offending line appears to be: 

- name: Update all packages to the latest version 
    become: true 
     ^here

首先：這不是劇本，因爲它不包含戲劇（其中必須包含hosts聲明），但任務。其次：你的縮進是非常糟糕的 - 在YAML中保持聲明正確對齊是非常重要的（也就是說，你看到的錯誤不是YAML語法錯誤，而是一個正確定義的錯誤數據導致的Ansible錯誤寫入YAML文件）。

如果你想在本地運行它，它看起來應該或多或少是這樣的：

--- 
- hosts: localhost 
    connection: local 
    tasks: 
    - name: Update all packages to the latest version 
     become: true 
     apt: 
     update_cache: yes  
     upgrade: dist 
     autoclean: yes 
     autoremove: yes
