Hello,
I tried to initialize a list and attach it to local host. I want to add to
the list across plays so that the hostname of each host that failed is
added to list but it seems that this does not work new list = old list +
new hostname of host that failed. Even if there are 3 hosts that failed the
list at the end of the play only contains one host. Here is my script, the
list is called continents.
---
- name: Create a array that persists across plays
hosts: localhost
gather_facts: no
tasks:
- name: create an array
set_fact:
continents: []
- name: see if array persists persists
hosts: all
become: yes
gather_facts: no
tasks:
- name: Get hostname
shell: |
hostname -f
register: host
- name: set a global variable
set_fact: my_global_var={{ host.stdout }}
- name: debug2
debug: var=my_global_var
- name: pre array
debug: var=hostvars['localhost'].continents
- block:
- name: invoke tasks that wil cause at least 2 hosts to fail
include_tasks: task.yml
vars:
nr: 10
n1: 10
rescue:
- name: list hostnames that failed
debug:
var: hostvars[inventory_hostname].my_global_var
- name: append to list
set_fact:
continents: "{{ hostvars['localhost'].continents + [
my_hostname_var ] }}"
delegate_to: localhost
delegate_facts: true
- name: post array
debug: var=hostvars['localhost'].continents
