I have stored checksum of local and remote files in two different variables. Now I want to compare those checksum and fail if they don't match. Below is code.
- name: Get cksum some of files copied locally
stat:
path : "{{ item.src }}/{{ item.file }}"
checksum_algorithm: sha1
delegate_to: localhost
with_items: "{{ files }}"
register: local_files
- name: Get cksum of remote files
stat:
path : "{{ item.dest }}/{{ item.file }}_{{ item.package }}_NEW"
checksum_algorithm: sha1
with_items: "{{ files }}"
register: remote_files
- name : Compare local and remote cksums. Fail if not matched
debug:
msg="Checksum don't match"
failed_when: item[0].results.stat.checksum != item[1].results.stat.checksum
with_items:
- "{{ local_files.results }}"
- "{{ remote_files.results }}"
When I run this, I get below error.
FAILED! => {"failed": true, "msg": "The conditional check 'item[0].results.stat.checksum != item[1].results.stat.checksum' failed. The error was: error while evaluating conditional (item[0].results.stat.checksum != item[1].results.stat.checksum): dict object has no element 0"}
How can I correct it to compare checksum?
Do this:
- name: Get cksum some of files copied locally
stat:
path : "{{ item.src }}/{{ item.file }}"
delegate_to: localhost
with_items: "{{ files }}"
register: local_files
- name: Get cksum of remote files
stat:
path : "{{ item.dest }}/{{ item.file }}"
with_items: "{{ files }}"
register: remote_files
- name: Compare local and remote cksums. Fail if not matched
fail:
msg: "Checksum don't match"
when: item[0].stat.checksum != item[1].stat.checksum
with_together:
- "{{ local_files.results }}"
- "{{ remote_files.results }}"

I am performing a grep with multiple items.
---
- hosts: my_host
gather_facts: false
vars:
my_list:
- whatever
- something
tasks:
- name: grep for item in search path
shell: "grep -rIL {{ item }} /tmp"
register: the_grep
loop: "{{ my_list }}"
- debug:
msg: "{{ item.stdout_lines }}"
loop: "{{ the_grep.results }}"
Depending on the result, multiple files could match.
msg:
- /tmp/something.conf
- /tmp/folder/file.txt
Q: How would I configure Ansible to loop over the items in stdout_lines?
The use case I'm solving is to delete .ini sections based on the item, but in this case, Ansible doesn't loop over the stdout_lines.
- name: remove stanza from ini file
ini_file:
path: "{{ item.stdout_lines }}"
section: "{{ item.item }}"
mode: '0600'
state: absent
loop: "{{ the_grep.results }}"
when: item.stdout_lines | length > 0
It seems that this doesn't work, but configuring item.stdout_lines[0] gives the partially expected result, since Ansible will use only the first item in that list. But ofc, not the 2nd and so on.
Perhaps there's a prettier answer, but solved it by using with_nested and creating a json_query:
- name: remove stanza from ini file
ini_file:
path: "{{ item.0 }}"
section: "{{ item.1.item }}"
mode: '0600'
state: absent
with_nested:
- "{{ the_grep | json_query('results[].stdout_lines[]') }}"
- "{{ the_grep.results }}"
I faced problems when I don't know how to pass many variables in with_items:
I have these vars:
- vars:
paths:
- /tmp/tecom/python3/
- /tmp/tecom/pip/
- /tmp/tecom/psycopg2/
- /tmp/tecom/docker/
- /tmp/tecom/postgresql/
files:
- python3.tar
- pip.tar
- psycopg2.tar
- docker.tar
- postgresql.tar
And I have the task that should extract the archives:
- name: unarchive "{{ item }}"
unarchive:
src: "{{ item }}"
dest: # should take the paths above. Every path should match it's own `.tar` file.
with_items: "{{ files }}"
Every path should match its own .tar file.
For example,
- debug:
msg: "unarchive {{ item }} to {{ _path }}"
loop: "{{ files }}"
vars:
_path: "{{ path }}/{{ item|splitext|first }}/"
path: /tmp/tecom
files:
- python3.tar
- pip.tar
- psycopg2.tar
- docker.tar
- postgresql.tar
gives (abridged)
msg: unarchive python3.tar to /tmp/tecom/python3/
msg: unarchive pip.tar to /tmp/tecom/pip/
msg: unarchive psycopg2.tar to /tmp/tecom/psycopg2/
msg: unarchive docker.tar to /tmp/tecom/docker/
msg: unarchive postgresql.tar to /tmp/tecom/postgresql/
Q: "How do I unarchive those files to the folders?"
A: Use the expressions as appropriate, e.g.
- name: "unarchive {{ item }}"
unarchive:
src: "{{ item }}"
dest: "{{ path }}/{{ item|splitext|first }}/"
loop: "{{ files }}"

It's up to you where you put the variables files and path. See Variable precedence: Where should I put a variable?
I'm looking for a way to sync files between 2 hosts in ansible. The scenario is as follows. I have a CSV file which contains 3 columns indicating directories which needs to be synced between 2 servers. the first 2 columns indicate the source and target servers and the third column indicates the directory
source, target, directory
src01, tgt02, dir0003
src02, tgt05, dir0004
src10, tgt68, dir1022
I found this answer for syncing files between 2 hosts - How to copy files between two nodes using ansible
Is there any way to parameterize this using a csv config file?
Yes. It's possible. In the first play read the CSV file and create group of targets. Use the new group in the second play and loop the synchronize module. For example the playbook
- hosts: localhost
tasks:
- read_csv:
path: db.csv
register: my_db
- add_host:
hostname: "{{ item.target }}"
groups: my_targets
my_list: "{{ my_db.list }}"
loop: "{{ my_db.list }}"
- hosts: my_targets
tasks:
- debug:
msg: "Copy {{ item.directory }} from {{ item.source }} to {{ inventory_hostname }}"
loop: "{{ my_list|json_query(query) }}"
vars:
query: "[?target == '{{ inventory_hostname }}']"
- name: Copy
synchronize:
src: "{{ item.directory }}"
dest: "{{ item.directory }}"
delegate_to: "{{ item.source }}"
loop: "{{ my_list|json_query(query) }}"
vars:
query: "[?target == '{{ inventory_hostname }}']"
(not tested)
gives
"msg": "Copy dir0004 from src02 to tgt05"
"msg": "Copy dir0003 from src01 to tgt02"
"msg": "Copy dir1022 from src10 to tgt68"
I have several files that I need to backup in different directories. I have tried the code below and not working for me.
vars:
file_vars:
- {name: /file1}
- {name: /etc/file2}
- {name: /etc/file/file3}
tasks:
- name: "Checking if config files exists"
stat:
path: "{{ item.name }}"
with_items: "{{ file_vars }}"
register: stat_result
- name: Backup Files
copy: src={{ item.name }} dest={{ item.name }}{{ ansible_date_time.date }}.bak
with_items: "{{ file_vars }}"
remote_src: yes
when: stat_result.stat.exists == True
The problem is the condition
when: stat_result.stat.exists == True
There is no attribute stat_result.stat. Instead, the attribute stat_result.results is a list of the results from the loop. It's possible to create a dictionary of files and their statuses. For example
- set_fact:
files_stats: "{{ dict(my_files|zip(my_stats)) }}"
vars:
my_files: "{{ stat_result.results|json_query('[].item.name') }}"
my_stats: "{{ stat_result.results|json_query('[].stat.exists') }}"
Then simply use this dictionary in the condition
when: files_stats[item.name]
Below is a shorter version which creates the dictionary more efficiently
- set_fact:
files_stats: "{{ dict(stat_result.results|
json_query('[].[item.name, stat.exists]')) }}"
Please try using below worked for me:
---
- name: Copy files
hosts: localhost
become: yes
become_user: root
vars_files:
- files.yml
tasks:
- name: "Checking if config files exists"
stat:
path: "{{ item }}"
with_items: "{{ files }}"
register: stat_result
- name: Ansible
debug:
msg: "{{ stat_result }}"
- name: Backup Files
copy:
src: "{{ item }}"
dest: "{{ item.bak }}"
with_items: "{{ files }}"
when: stat_result == "True"
and files.yml will look like:
---
files:
- /tmp/file1
- /tmp/file2
you can check you playbook syntax using below command:
ansible-playbook copy.yml --syntax-check
Also you do dry run your playbook before actual execution.
ansible-playbook -i localhost copy.yml --check
I am trying to run win_find with variables for "paths" to find temp files (e.g. c:\users\public\appdata\local\temp) but when I pass it to debug I get the error message
"FAILED! => {"msg": "'dict object' has no attribute 'files'"}"
I have tried swapping the "register" and "with_items" lines but that seems to make no difference at all.
- hosts: windows-02
vars:
dir: \AppData\Local\Temp\
tasks:
- name: find user directories
win_find:
paths: c:\users
recurce: yes
file_type: directory
get_checksum: no
register: user_dir
- name: debug 1
debug:
msg: "{{ item.path + dir }}"
loop: "{{ user_dir.files }}"
- name: find temp files
win_find:
paths: "{{ item.path + dir }}"
recurce: yes
hidden: yes
get_checksum: no
register: files_to_delete
with_items: "{{ user_dir.files }}"
- name: debug
debug:
msg: "{{ item }}"
loop: "{{ files_to_delete.files }}"
- name: remove
win_file:
path: "{{ item.path }}"
state: absent
with_items: "{{ files_to_delete.files }}"
I expect to get a list of files to be deleted which will be passed to the "win_files" module. Instead I'm getting the error message
"FAILED! => {"msg": "'dict object' has no attribute 'files'"}"
There is a typo in win_find module, it is recurse: yes
Please find the below code whcih worked for me
---
- name: Find files
win_find:
paths: "{{paths}}"
age: "{{duration}}"
register: log_files
- name: Delete the files
win_file:
path: "{{item.path}}"
state: absent
with_items: "{{log_files.files}}"
Also files_to_delete will not have files_to_delete.files as it is in loop. It will have files_to_delete.results
So, it appears that win_find, at least in my case, does not return files when using "when_items". I got around this by creating a list of paths and passing it into the "paths" parameter of the module.
Here is my code:
- hosts: "{{ host }}"
vars:
dir: \AppData\Local\Temp\
temp_paths: []
line_break: \n
tasks:
- name: find user directories
win_find:
paths: c:\users
recurse: no
file_type: directory
get_checksum: no
register: user_dir
- name: debug 1
debug:
msg: "{{ item.path + dir }}"
loop: "{{ user_dir.files }}"
- name: set temp path
set_fact: temp_paths="{{temp_paths + [ item.path + dir ] }}"
when: item.path != 'C:\\users\\Public'
with_items: "{{ user_dir.files }}"
- name: find temp files
win_find:
paths: "{{ temp_paths }}"
recurse: True
patterns: '*'
hidden: False
get_checksum: False
register: files_to_delete
# ignore_errors: yes
- name: debug
debug:
msg: "{{ item.path }}"
loop: "{{ files_to_delete.files }}"
- name: remove
win_file:
path: "{{ item.path }}"
state: absent
with_items: "{{ files_to_delete.files }}"
