Here is my main.yml
---
- name: Gathering VCenter facts
vmware_vm_info:
hostname: "{{ vcenter_server }}"
username: "{{ vcenter_user }}"
password: "{{ vcenter_pass }}"
validate_certs: false
register: vcenter_facts
delegate_to: localhost
- debug:
var: vcenter_facts.virtual_machines
- name: Find all test-vms to run IO
set_fact:
vm_ip: "{{ item.ip_address }}"
loop: "{{ vcenter_facts.virtual_machines }}"
when: item.guest_name is regex("test_vm*")
- name: print vm_ip variable value
debug:
var: vm_ip
- name: Mount 16TB dropbox in each test vm
shell: mount-16tb-dropbox.sh
args:
chdir: /usr/local/bin/
with_items: "{{ vm_ip }}"
And here is the recap:

I am not able to loop through all the ip_address
variable (i.e. 192.168.202.12
, 192.168.202.13
, 192.168.202.14
).
It just reads the last item (i.e. 192.168.202.14
).
What am I possibly doing wrong with set_fact
that it is not reading all the variable and performing the set of tasks that follows?

Answers
This should give all the IP. You correctly assumed where the code may need correction. In the code,
vm_ip
variable was overwritten by each loop and the last IP remained. What you need is a list and then append each IP to the list.Alternative solution using
Jinja2 filters
.An alternate solution using
json_query
Note:
to_json | from_json
is a workaround for a bug between ansible and jmespath so that all values can be converted to real strings and can be used with the jmespathcontains
function.
