在 Ansible 问题中创建然后编辑文件 (authorized_keys)

Question

我正在使用 ansible 完成两个简单的任务。

首先我创建了一个包含内容的新文件（我执行的角色）：

- name: Add keys to authorized_keys
  blockinfile:
        owner: user
        group: user
        mode: '0600'
        create: yes
        path: /home/user/.ssh/authorized_keys
        block: |
                line if text
                other line
                more lines

第二个任务（我如何执行第二个角色）：

- name: Add more keys to authorized_keys root
  blockinfile:
        path: /home/user/.ssh/test_keys
        block: |
                other and more keys

问题是在执行第二个任务时，文件中现有的行被删除，只剩下第二个任务的行。我应该怎么做才能添加新行而不是删除现有行？

Answer 1

Q: "Existing lines in the file are deleted and only those of the second task remain. What should I do to add the new lines and not delete the existing ones?"

A：设置唯一的marker_begin和marker_end块。例如

- name: Add keys to authorized_keys
  blockinfile:
    marker_begin: "BEGIN BLOCK1"
    marker_end: "END BLOCK1"
    owner: user
    group: user
    mode: '0600'
    create: yes
    path: /home/user/.ssh/authorized_keys
    block: |
      line if text
      other line
      more lines

- name: Add more keys to authorized_keys root
  blockinfile:
    marker_begin: "BEGIN BLOCK2"
    marker_end: "END BLOCK2"
    path: /home/user/.ssh/authorized_keys
    block: |
      other and more keys
