机器需要准备。在 CI 中，这可以通过 molecule/default/prepare.yml 完成：

---
- name: Prepare
  hosts: all
  become: true
  gather_facts: false

  roles:
    - role: buluma.bootstrap
    - role: buluma.cron

  post_tasks:
    - name: 创建日志目录
      ansible.builtin.file:
        path: "{{ item }}"
        state: directory
        mode: "0755"
      loop:
        - /var/log/example
        - /var/log/example-frequency
        - /var/log/example-keep
        - /var/log/example-compress
        - /var/log/example-copylog
        - /var/log/example-copytruncate
        - /var/log/example-delaycompress
        - /var/log/example-script
        - /var/log/example-sharedscripts
        - /var/log/example-dateyesterday

    - name: 创建日志文件
      ansible.builtin.copy:
        dest: "{{ item }}"
        content: "example"
        mode: "0644"
      loop:
        - /var/log/example/app.log
        - /var/log/example-frequency/app.log
        - /var/log/example-keep/app.log

角色变量

变量的默认值在 defaults/main.yml 中设置：

---
# logrotate 的默认文件

# 日志轮换的频率，可以是 daily（每日）、weekly（每周）或 monthly（每月）。
logrotate_frequency: weekly

# 保留多少个文件。
logrotate_keep: 4

# 是否应压缩轮换的日志文件？
logrotate_compress: true

# 在日志文件名上使用日期扩展
logrotate_dateext: false

# 轮换日志文件的用户/组（如果找到则由特定操作系统的变量加载，也可以手动设置）
logrotate_user: "{{ _logrotate_user[ansible_distribution] | default(_logrotate_user['default']) }}"
logrotate_group: "{{ _logrotate_group[ansible_distribution] | default(_logrotate_group['default']) }}"

# 设置服务的状态
logrotate_service_state: "started"
logrotate_service_enabled: true
