I want to execute a task only when multiple files exist . if only single file is exist i need to ignore this task. How can i achieve this.
Am unable to achieve with the below playbook
---
- name: Standardize
hosts: test
gather_facts: false
vars:
file_vars:
- {id: 1, name: /etc/h_cm}
- {id: 2, name: /etc/H_CM}
tasks:
- block:
- name: Check if both exists
stat:
path: "{{ item.name }}"
with_items: "{{ file_vars }}"
register: cm_result
- name: Move both files
shell: mv "{{ item.item }}" /tmp/merged
with_items: "{{ cm_result.results }}"
when: item.stat.exists
After check if both exist task, you can add a set fact task like this one:
- name: set facts
set_fact:
files_exist: "{{ (files_exist | default([])) + [item.stat.exists] }}"
with_items: "{{ cm_result.results }}"
And you change your move files task to:
- name: Move both files
debug:
msg: "{{ item.stat.exists }}"
with_items: "{{ cm_result.results }}"
when: false not in files_exist
You have to specify shell: mv "{{ item.item.name }}" /tmp/merged insted of shell: mv "{{ item.item }}" /tmp/merged
Check the below works?:
- name: Standardize
hosts: test
gather_facts: false
become: yes ## If needed
vars:
file_vars:
- {id: 1, name: /etc/h_cm}
- {id: 2, name: /etc/H_CM}
tasks:
- block:
- name: Check if both file exists
stat:
path: "{{ item.name }}"
with_items: "{{ file_vars }}"
register: cm_result
- debug:
var: item.stat.exists
loop: "{{ cm_result.results }}"
- name: Crate a dummy list
set_fact:
file_state: []
- name: Add true to list if file exists
set_fact:
file_state: "{{ file_state }} + ['{{ item.stat.exists }}']"
loop: "{{ cm_result.results }}"
when: item.stat.exists == true
- name: Move both files
shell: mv "{{ item.item.name }}" /tmp/merged
loop: "{{ cm_result.results }}"
when: file_state|length > 1

I want to have text file which contains name and password
name: "Peter", "Joe", "Mark"
password: "smith", "biden", "garyy"
And I have playbook like this
---
- hosts: myhosts
become: yes
remote_user: root1
become_user: root
vars_files:
- vars.yml
vars:
ansible_ssh_private_key_file: "{{key}}"
tasks:
- name: Create users
user: name="{{item.name}}" shell=/bin/bash home="/srv/{{item.name}}" groups=root generate_ssh_key=yes ssh_key_bits=2048
loop: "{{ lookup('file', 'userspasswd.txt', wantList=True)| list }}"
- name: Set password to users
shell: echo "{{item.name}}:{{item.password}}" | sudo chpasswd
no_log: True
loop: "{{ lookup('file', 'userspasswd.txt', wantList=True)| list }}"
I am getting error like this
fatal: [xxx.xxx.xxx.xxx]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'ansible.utils.unsafe_proxy.AnsibleUnsafeText object' has no attribute 'name'\n\nThe error appears to be in '/home/root1/Documents/ansiblekernel/main.yml': line 12, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n - name: Create users\n ^ here\n"}
Is there any correct way of doing this? Cause I am new to this?
Given the file
shell> cat userspasswd.txt
name: "Peter", "Joe", "Mark"
password: "smith", "biden", "garyy"
Neither wantList=True nor the filter list will help you to parse the file because it's not a valid YAML. If you can't change the structure of the file you'll have to parse it on your own.
Declare the variables
userspasswd_lines: "{{ lookup('file', 'userspasswd.txt').splitlines() }}"
userspasswd_values: "{{ userspasswd_lines|
map('split', ':')|
map('last')|
map('regex_replace', '\"', '')|
map('split', ',')|
map('map', 'trim')|
list }}"
userspasswd_dict: "{{ dict(userspasswd_values.0|
zip(userspasswd_values.1)) }}"
give
userspasswd_lines:
- 'name: "Peter", "Joe", "Mark"'
- 'password: "smith", "biden", "garyy"'
userspasswd_values:
- - Peter
- Joe
- Mark
- - smith
- biden
- garyy
userspasswd_dict:
Joe: biden
Mark: garyy
Peter: smith
Iterate the dictionary. Test it

I want to create multiple logical volumes with a variable file but it return a sintax error found character that cannot start any token, I have tried in different ways but still doesn't work
main.yml
---
- name: playbook for create volume groups
hosts: localhost
become: true
tasks:
- include_vars: vars.yml
- name: Create a logical volume
lvol:
vg: vg03
lv: "{{ item.var1 }}"
size: "{{ item.var2 }}"
with_items:
- { var1: "{{ var_lv_name }}", var2: "{{ var_lv_size }}" }
vars.yml
var_lv_name:
- lv05
- lv06
var_lv_size:
- 1g
- 1g
Use with_together. Test it first. For example,
- debug:
msg: "Create lv: {{ item.0 }} size: {{ item.1 }}"
with_together:
- "{{ var_lv_name }}"
- "{{ var_lv_size }}"
gives (abridged)
msg: 'Create lv: lv05 size: 1g'
msg: 'Create lv: lv06 size: 1g'
Optionally, put the declaration below into the file vars.yml
var_lv: "{{ var_lv_name|zip(var_lv_size) }}"
This creates the list
var_lv:
- [lv05, 1g]
- [lv06, 1g]
Use it in the code. The simplified task below gives the same results
- debug:
msg: "Create lv: {{ item.0 }} size: {{ item.1 }}"
loop: "{{ var_lv }}"
The previous answer it's totally correct but In my humble opinion we should be getting into the new way to do the things with loop and filters.
Here's my answer:
---
- name: playbook for create volume groups
hosts: localhost
gather_facts: no
become: true
vars_files: vars.yml
tasks:
- name: Create a logical volume
lvol:
vg: vg03
lv: "{{ item[0] }}"
size: "{{ item[1] }}"
loop: "{{ var_lv_name | zip(var_lv_size) | list }}"
In this answer you're using the new way to use loops with keyword loop and using filters like zip and turning the result into a list type for iteration in the loop.
my host_vars file has about 5k lines of yml code. So I would like to have separate yml files - one file per one service.
Simplified example:
user#test $ cat production/split_configs/a.example.net.yml
my_array:
- a.example.net
user#test $ cat production/split_configs/b.example.net.yml
my_array:
- b.example.net
user#test $ cat webhosts.yml
- hosts: myservers
pre_tasks:
- name: merge ansible arrays
tags: always
delegate_to: localhost
block:
- name: find config files
find:
paths: production/configs/
patterns: '*.yml'
register: find_results
- name: aaa
debug:
msg: "{{ find_results.files }}"
- name: bbb
debug:
msg: "{{ item.path }}"
with_items: "{{ find_results.files }}"
- name: ccc
debug:
msg: "{{ lookup('file', 'production/configs/a.example.net.yml') }}"
- name: ddd
debug:
msg: "{{ lookup('file', item.path) }}"
loop: "{{ find_results.files }}"
tasks:
- name: eee
debug:
msg: "{{ my_array }}"
The goal is to merge content of both arrays an print the merged content in task eee:
my_array:
- a.example.net
- b.example.net
Task aaa print informations about files (path, mode, uid, ...) - it works.
Tasks bbb, and ddd print nothing. I do not understand why.
Task ccc print content of file. But the path is written in playbook :-(
After load files I need to merge them. My idea is to use something like set_fact: my_array="{{ my_array + my_array }}" in task with with_items: "{{ find_results.files }}". Is it good idea? Or how better I can do it?
For example, the tasks below do the job
- include_vars:
file: "{{ item }}"
name: "my_prefix_{{ item|regex_replace('\\W', '_') }}"
with_fileglob: production/split_configs/*
- set_fact:
my_vars: "{{ my_vars|d({})|
combine(lookup('vars', item),
recursive=True,
list_merge='append') }}"
loop: "{{ q('varnames', 'my_prefix_.*') }}"
give
my_vars:
my_array:
- a.example.net
- b.example.net
You can use the simple cat commnd to merge the files into the one file and later include var file for example -
- raw: "cat production/split_configs/* >my_vars.yml"
- include_vars: file=my_vars.yml name=my_vars
will give you the result -
my_vars:
my_array:
- a.example.net
- b.example.net
I have trying to extend the VG via ansible passing the pvname by variable, however I really don't understand why is not working.
Below you can see my code.
Variable file:
new_disk:
- diskname: /dev/sdc
pvname: /dev/sdb1, dev/sdc1
vgname: datavg
lvm_settings:
- lv_name: datalv
lv_size: +100%FREE
fs_name: ansible_fs_test
lvpath: /dev/mapper/datavg-datalv
filesystem_type: ext4
tasks file:
include_vars: "{{ vm_name }}.yml"
- name: First disk partition settings
block:
- name: Create a new primary partition
community.general.parted:
device: "{{ item.diskname }}"
number: 1
state: present
with_items: "{{ new_disk }}"
register: partition_status
rescue:
- name: Debug messages to check the error
debug:
msg: "{{ partition_status }}"
- name: Extending the Volume Group
community.general.lvg:
vg: "{{ vgname }}"
pvs: "{{ pvname }}"
pvresize: yes
Below, you can see the error message:

Do you know have any idea why is not working?
I really appreciate your help and time

For it works that way:

I have to update sudoers.d multiple user files with few lines/commands using ansible playbook
users.yml
user1:
- Line1111
- Line2222
- Line3333
user2:
- Line4444
- Line5555
- Line6666
main.yml
- hosts: "{{ host_group }}"
vars_files:
- ../users.yml
tasks:
- name: Add user "user1" to sudoers.d
lineinfile:
path: /etc/sudoers.d/user1
line: '{{ item }}'
state: present
mode: 0440
create: yes
validate: 'visudo -cf %s'
with_items:
- "{{ user1 }}"
The above one is working only for user1..
If I want to also include user2 --> How to change the file name : path: /etc/sudoers.d/user1
I tried below and its not working :
Passing below users as variable to main.yml while running
users:
- "user1"
- "user2"
- name: Add user "{{users}}" to sudoers.d
lineinfile:
path: /etc/sudoers.d/{{users}}
line: '{{ item }}'
state: present
mode: 0440
create: yes
validate: 'visudo -cf %s'
with_items:
- "{{ users }}"
So, basically I want to pass in users to a variable {{users}} as user1 and user2 and wanted to use the lines for each user from users.yml and add it to respective user files (/etc/sudoers.d/user1 and /etc/sudoers.d/user2).
So /etc/sudoers.d/user1 should look like
Line1111
Line2222
Line3333
and /etc/sudoers.d/user2 should look like
Line4444
Line5555
Line6666
Try to add quotes:
users:
- "user1"
- "user2"
- name: "Add user {{users}} to sudoers.d"
lineinfile:
path: "/etc/sudoers.d/{{users}}"
line: "{{ item }}"
state: present
mode: 0440
create: yes
validate: 'visudo -cf %s'
with_items:
- "{{ users }}"
As per Ansible Documentation on Using Variables:
YAML syntax requires that if you start a value with {{ foo }} you quote the whole line, since it wants to be sure you aren’t trying to start a YAML dictionary. This is covered on the YAML Syntax documentation.
This won’t work:
- hosts: app_servers
vars:
app_path: {{ base_path }}/22
Do it like this and you’ll be fine:
- hosts: app_servers
vars:
app_path: "{{ base_path }}/22"
