I have below inventory file:
[web]
10.0.1.0
[db]
10.0.3.0
[frontend]
10.0.5.0
[X_all:children]
web
db
frontend
Now in my playbook: I'm trying to print the hostname under X_all group in the name line.
- name: "Copying the output of Registry run to local machine from {{ hostvars[item]['inventory_hostname'] }}"
become: true
become_user: "{{ login }}"
fetch:
src: /tmp/DeploymentRegistry.txt
dest: /tmp/DeploymentRegistry-{{ inventory_hostname }}.txt
flat: yes
with_items:
- "{{ groups['X_all'] }}"
Is it even possible to add the hostname in the name line?
I tried replacing {{ hostvars[item]['inventory_hostname'] }} with inventory_hostname but it's also not working.
Regarding your requirement
I'm trying to print the hostname under test group in the name line.
take note that the group has more than one member and therefore more than one hostname, but a list of hostnames.
- name: Show hosts {{ groups['test'] }}
delegate_to: localhost
debug:
msg: "{{ item }}" # will show the group member hostname(s)
with_items:
- "{{ groups['test'] }}"
Is it even possible to add the hostname in the name line? I tried ... with inventory_hostname but it's also not working.
Yes, it is.
- name: Show host {{ inventory_hostname }}
debug:
msg: "{{ item }}"
with_items:
- "{{ groups['test'] }}"
But it will print the first hostname from list only.

I'm trying to get the inventory host group names by below process which is not working
- debug:
msg: "{{ groups['{{ item }}'] }}"
with_items: "{{ vm.stdout_lines }}"
this is what actually I'm trying to do
I will get a list of servers by a shell script
- name: Getting the servers list
shell: |
sh getServers.sh
register: vm
Then adding them into inventory by add_host
- name: Creating Logical host_group for each server
add_host:
name: "{{ item }}"
groups: ["{{item }}"]
with_items: "{{ vm.stdout_lines }}"
register: inv
Here I'm trying to get the only groups I've added in above step instead of all groups
- debug:
msg: "{{ groups['{{ item }}'] }}"
with_items: "{{ vm.stdout_lines }}"
Error is
{"msg": "The task includes an option with an undefined variable. The error was: 'dict object' has no attribute '{{ item }}'
Appreciate help on this!
Fix the syntax

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 want to create playbook that going on the entire inventory file and divide the servers to 2 groups: Windows and Linux (add-host going only on the first server on the inv)
I tried this code:
- name: Linux Group
add_host:
name: "{{ item }}"
group: LinuxGroup
when: hostvars[" {{ item }} "]['ansible_system'] == 'Linux'
with_items: "{{ ansible_play_hosts_all }} "
This code suppose to create the linux group
and I tried with other conditions of when but non was a succsess. I would like to get your help please.
PS:
I changed the code to this:
tasks:
- name: Create linux group
add_host:
name: "{{ item }}"
group: LinuxGroup
when: hostvars[item].ansible_system == 'Linux'
with_items: "{{ ansible_play_hosts_all }} "
ignore_errors: yes
- name: ping to Linux
ping:
with_items: LinuxGroup
and when I run the code the windows servers are skipped in the "Create linux group" task, but I used the module debug to print to group's items and there are the windows servers.
The fact ansible_system is a key under the host, not a list of keys. Also, conditional statements should not include jinja2 templating delimiters such as {{ }} or {% %}, use hostvars[item] instead of hostvars[ "{{ item }}" ].
Make sure gather_facts is set to true.
Note that the add_host module does not update the inventory file but updates the in-memory inventory. I have included a debug task to print the groups from the in-memory inventory of ansible.
gather_facts: true
tasks:
- name: Linux Group
add_host:
name: "{{ item }}"
group: LinuxGroup
when: hostvars[item].ansible_system == 'Linux'
with_items: "{{ ansible_play_hosts_all }}"
- debug: msg="{{ groups }}"
Below is the condition
- name: Find the image
slurp:
src: "{{ IMAGE }}"
register: slurp_results
- name: Upload image
shell: |
skopeo copy -docker-archive:{{ item }}.tar docker://{{ URL }}/TESTIMAGE
with_items: "{{ (slurp_results.content|b64decode).splitlines() }}"
The above code works.
But I would need "TESTIMAGE" also to be replaced as {{ item }} like below.
skopeo copy -docker-archive:{{ item }}.tar docker://{{ URL }}/{{ item }}
How to define 2 with_items in a single shell task with 2 different slurp results
I believe you can by using the subelements module. Here is a link. Try going by this example:
- name: Setup MySQL users, given the mysql hosts and privs subkey lists
mysql_user:
name: "{{ item.0.name }}"
password: "{{ item.0.mysql.password }}"
host: "{{ item.1 }}"
priv: "{{ item.0.mysql.privs | join('/') }}"
with_subelements:
- "{{ users }}"
- mysql.hosts
Users is referred to as item.0 and hosts as item.1 and so on.
I have an assignment to provision {{ create new hosts }} according to a given
invonteroy file,
example
[SET1]
1.1.1.1 new_ip=1.1.1.1
[SET2]
1.1.1.2 new_ip=1.1.1.2
[SET3]
1.1.1.3 new_ip=1.1.1.3
Here is the problem. The inventory file contains set of ip addresses that do not exists yet.
What I want to do
- connect to vsphere host(5.5)
- create new machines based on amount of hosts in the inventory
- change the machines ip address to match the one in the given inventory
modules like
vmware_shell
vmware_guest
requires administrative permissions which I don't have.
The only way to hack around this issue is to try and create an in memory or temporary inventory during provisioning task.
Here is my role:
- vsphere_guest:
vcenter_hostname: {{ vcenter }}
validate_certs: no
username: "{{ vsphere.username }}"
password: "{{ vsphere.password }}"
guest: "{{ item }}"
from_template: yes
template_src: Centos_base
resource_pool: "/Resources"
esxi:
datacenter: Remote
hostname: {{ esx_host }}
with_items:
- "{{ play_hosts }}"
- name: wait for power on to finish
pause: seconds=5
- name: get facts from vm
vsphere_guest:
validate_certs: False
vcenter_hostname: {{ vcenter }}
username: "{{ vsphere.username }}"
password: "{{ vsphere.password }}"
guest: "{{ item }}"
vmware_guest_facts: yes
with_items:
- "{{ play_hosts }}"
register: vm_facts
until: vm_facts.ansible_facts.hw_eth0.ipaddresses[0] is defined
retries: 10
delay: 10
- name: grab new ipaddresses
set_fact: myIp="{{ inventory_hostname }}"
- name: Add production VMs to inventory
add_host: hostname={{item.ansible_facts.hw_eth0.ipaddresses[0] }} groups=temp
new_ip={{ myIp }}
with_items: "{{ vm_facts.results }}"
ignore_errors: yes
my question:
is there any way to create a temp inventory with multiple groups and mutilple variables that matches the given inventory!?
update
I hacked a way around it:
- name: Add production VMs to inventory
add_host: hostname={{item.ansible_facts.hw_eth0.ipaddresses[0] }} groups=temp
new_ip="{{ item.ansible_facts.hw_name }}"
with_items: "{{ vm_facts.results }}"
ignore_errors: yes
this works since the machine name is equal to {{ play_host }}
