Place file contents in email body in Ansible - ansible

Question

I have a playbook that checks hard drive space on a group of servers, sends out an email, and it attaches a file containing the output contents. Is there a way to place the contents of the file in the body itself? I would like the file contents to be able to be seen at a glance in the email. The content would be the registered variable, result.
The current tasks:
---
- name: Check for output file
stat:
path: /tmp/ansible_output.txt
register: stat_result
delegate_to: localhost
- name: Create file if it does not exist
file:
path: /tmp/ansible_output.txt
state: touch
mode: '0666'
when: stat_result.stat.exists == False
delegate_to: localhost
- name: Check hard drive info
become: yes
become_user: root
shell: cat /etc/hostname; echo; df -h | egrep 'Filesystem|/dev/sd'
register: result
- debug: var=result.stdout_lines
- local_action: lineinfile line={{ result.stdout_lines | to_nice_json }} dest=/tmp/ansible_output.txt
- name: Email Result
mail:
host: some_email_host
port: some_port_number
username: my_username
password: my_password
to:
- first_email_address
- second_email_address
- third_email_address
from: some_email_address
subject: My Subject
body: <syntax for file contents in body here> <--- What is the syntax?
attach:
/tmp/ansible_output.txt
run_once: true
delegate_to: localhost
- name: Remove Output File
file:
path: /tmp/ansible_output.txt
state: absent
run_once: true
delegate_to: localhost
Edit: I tried
body: "{{ result.stdout_lines | to_nice_json }}"
but it only sends me the output of the first host in the group.

Ok, I figured it out. I created a directory, files, and sent the output to a file in that directory using the {{ role_path }} variable. In the body portion of the email task, I used the lookup plugin to grab the contents of the file.
Here is the updated playbook with the original lines commented out:
---
- name: Check for output file
stat:
#path: /tmp/ansible_output.txt
path: "{{ role_path }}/files/ansible_output.txt"
register: stat_result
delegate_to: localhost
- name: Create file if it does not exist
file:
#path: /tmp/ansible_output.txt
path: "{{ role_path }}/files/ansible_output.txt"
state: touch
mode: '0666'
when: stat_result.stat.exists == False
delegate_to: localhost
- name: Check hard drive info
become: yes
become_user: root
shell: cat /etc/hostname; echo; df -h | egrep 'Filesystem|/dev/sd'
register: result
- debug: var=result.stdout_lines
#- local_action: lineinfile line={{ result.stdout_lines | to_nice_json }} dest=/tmp/ansible_output.txt
- local_action: lineinfile line={{ result.stdout_lines | to_nice_json }} dest="{{ role_path }}/files/ansible_output.txt"
- name: Email Result
mail:
host: some_email_host
port: some_port_number
username: my_username
password: my_password
to:
- first_email
- second_email
- third_email
from: some_email_address
subject: Ansible Disk Space Check Result
#body: "{{ result.stdout_lines | to_nice_json }}"
body: "{{ lookup('file', '{{ role_path }}/files/ansible_output.txt') }}"
#attach:
#/tmp/ansible_output.txt
attach:
"{{ role_path }}/files/ansible_output.txt"
run_once: true
delegate_to: localhost
- name: Remove Output File
file:
#path: /tmp/ansible_output.txt
path: "{{ role_path }}/files/ansible_output.txt"
state: absent
run_once: true
delegate_to: localhost
Now, my email contains the attachment, as well as the contents in the body, and I didn't have to change much in the playbook. :-)
