不可用动态文件名发送电子邮件

Question

我需要使用Ansible从远程服务器复制日志文件，重命名它们并通过电子邮件作为附件发送。

我创造了这个剧本：

---
 - hosts: WebAccessServers
   vars:
    date: "{{ lookup('pipe', 'date +%Y%m%d') }}"
   tasks:
     - name: copy web access log file from Web servers to Ansible Server and rename it
       fetch:
        src: /var/www/html/mywebapp/logs/access.log
        dest: /tmp/{{ date }}_{{ inventory_hostname }}_access.log
        flat: yes
        ignore_errors: true
        delegate_to: localhost

 - hosts: localhost
   vars:
    date: "{{ lookup('pipe', 'date +%Y%m%d') }}"
   tasks:
     - name: create variable for the attachments
       shell: "ls /tmp/{{ date }}_*.log"
       register: command_output
     - debug: msg="{{ command_output.stdout_lines }}"

     - name: Send Emails to a bunch of users, with Playbook Report as an attachment.
       mail:
        host: mysmtp.mydomain.com
        port: 25
        subject: Ansible Playbook Report
        body: This is an Email generated using Ansible after execution of task.
        from: ansibbe@gmydomain.com (Ansible Automates)
        to:
        - John Brown <j.ba@mydomain.com>
        attach:
        - "{{  command_output.stdout_lines }}"
        headers:
        - Reply-To=ansible@domain.com
        - X-Special="Write something special about this Email"
        charset: us-ascii

如果运行它，就会收到以下输出：

ignored=0 localhost : ok=3 changed=1 unreachable=0 failed=1

在电子邮件中动态和递归地分配附加内容的最佳方法是什么？谢谢你的支持。马可

这是我的工作解决方案：

 - hosts: myapp
   vars:
    date: "{{ lookup('pipe', 'date +%Y%m%d') }}"
   tasks:
     - name: copy access_allowed log file from MyApp servers

     - name: Ansible delete log file
       shell: sudo rm -rf /var/www/html/myapp/logs/access*.log

     - name: Send Emails to a bunch of users, with Playbook Report as an attachment.
       mail:
        host: my.smtp.local
        port: 25

        attach: "{{ command_output.stdout_lines | join(',') }}"
        headers:
        - Reply-To=ansible@mydomain.com
        - X-Special="Write something special about this Email"
        charset: us-ascii

     - name: Ansible delete log file
       shell: sudo rm -rf /tmp/*access*.log

  tasks:

    - name: Create variable for the attachments
      shell: "ls *.log"
      register: log_files
    - debug: msg="{{ log_files.stdout_lines | list | join(',') }}"

- name: Email logs
  community.general.mail:

        attach: "{{ log_files.stdout_lines | list | join(',') }}"
