Create a playbook called hwreport.yml that produces an output file called /root/

hwreport.txt on all managed nodes with the following information:

------------------------------------------------------------------------------------------------------

--> Inventory host name

--> Total memory in MB

--> BIOS version

--> Size of disk device vda

--> Size of disk device vdb

Each line of the output file contains a single key-value pair.

* Your playbook should:

--> Download the file hwreport.empty from the URL http://classroom.example.com/

hwreport.empty and

save it as /root/hwreport.txt

--> Modify with the correct values.

note: If a hardware item does not exist, the associated value should be set to NONE

----------------------------------------------------------------------------------------------

while practising you to create these file hear. But in exam have to download as per

questation.

hwreport.txt file consists.

my_sys=hostname

my_BIOS=biosversion

my_MEMORY=memory

my_vda=vdasize

my_vdb=vdbsize

AExplanation:
Solution as:
# pwd
/home/admin/ansible
# vim hwreport.yml
- name:
hosts: all
ignore_errors: yes
tasks:
- name: download file
get_url:
url: http://classroom.example.com/content/ex407/hwreport.empty
dest: /root/hwreport.txt
- name: vdasize
replace:
regexp: 'vdasize'
replace: '{{ ansible_facts.devices.vda.size }}'
dest: /root/hwreport.txt
register: op1
- debug:
var: op1
- name: none
replace:
regexp: 'vdasize'
replace: NONE
dest: /root/hwreport.txt
when:
op1.failed == true
- name: vdbsize
replace:
regexp: 'vdbsize'
replace: '{{ ansible_facts.devices.vdb.size }}'
dest: /root/hwreport.txt
register: op2
- debug:
var: op2
- name: none
replace:
regexp: 'vdbsize'
replace: NONE
dest: /root/hwreport.txt
when:
op2.failed == true
- name: sysinfo
replace:
regexp: '{{item.src}}'
replace: '{{item.dest}}'
dest: /root/hwreport.txt
loop:
- src: 'hostname'
dest: '{{ ansible_facts.fqdn }}'
- src: 'biosversion'
dest: '{{ ansible_facts.bios_version }}'
- src: 'memory'
dest: '{{ ansible_facts.memtotal_mb }}'
:wq!

This is a solid approach, but I'm not sure about the error handling part.

Wait, does it really set values to NONE if the hardware is missing?

I think the URL in the playbook is wrong.

Totally agree, but what if vdb doesn't exist?

Sounds straightforward, just need to pull the right facts.

I recall we had to use a loop for replacing multiple values in a file, so I hope I can remember how to set that up correctly in this playbook.

I feel confident about downloading the file with get_url, but I’m worried I might mix up the variables for memory and BIOS version in the output.

I think we did a similar question where we had to check for device sizes, but I’m not clear on how to handle the "NONE" value if a device doesn’t exist.

I remember we practiced creating playbooks that gather system information, but I’m a bit unsure about the exact syntax for the replace module.

This exam question looks pretty straightforward, but I want to make sure I don't miss anything. I'm going to carefully read through the requirements one more time to make sure I understand exactly what I need to do. Then I'll start building out the playbook step-by-step.

Okay, I think I've got a good strategy for this. First, I'll use the get_url module to download the hwreport.empty file. Then, I'll use the replace module to swap out the placeholders with the actual system facts. And if any of the hardware items don't exist, I'll set the value to "NONE". Feels like a good plan!

Hmm, I'm a bit confused about the part where we need to set the values to "NONE" if the hardware item doesn't exist. Not sure how to handle that properly in the playbook. Might need to do some research on the Ansible replace module.

This looks like a pretty straightforward task. I think I can handle this - just need to download the file, replace the placeholders with the actual system information, and save the output. Shouldn't be too difficult.

The playbook looks great, but I'm a little worried about the `ignore_errors` setting. What if something goes wrong during the execution, and we miss important information in the output file? Maybe we could add some error handling instead.
