Thank you so much for this.
I have now been able to use thesame login in my ansible role, and it
appears to work.
- name Unreachable servers
set_fact:
down: "{{ ansible_play_hosts_all | difference(ansible_play_hosts)}}"
- name: Set Execution File and parameters
set_fact:
scriptfile: "{{ansible_user_dir}}\\scripts\\host_check.ps1"
params: "-servername '{{the_host_name}}' -response var_ping.failed
-unreachable_hosts {{ down }}"
- name: Execute script
win_command: powershell.exe "{{scriptfile}}" "{{params}}"
when: inventory_hostname == {{ db_server_host }}
I do however have some questions. My playbook runs against hosts defined in
my inventory, in this case what I want to achieve is a situation where the
unreachable hosts is passed onto a powershell script right at the end and
at once. So for example, 100 hosts, 10 were unreachable. The playbook
should gather the 10 unreachable hosts, and pass the list of hosts in an
array format to a powershell script or as a json data type.
All I want to do is be able to process the list of unreachable servers from
my powershell script.
At the moment, I get
[ "server1", "server2" ]
MY script will work with a format like this "server1","server2"
Lastly.The process of logging the unreachable servers at the end, only
needs to happen once to a specific server which does the logging to a
database. I created a task to do this as seen above.
db_server_host is being passed as a extra variables from ansible tower. The
reason i added the when is that I only want it to run on the DB server and
not on every host. I get the error The conditional check inventory_hostname
== {{ db_server_host }} failed. The error was error while evaluating
conditional inventory_hostname == {{ db_server_host }}
'mydatabaseServerName' is undefined
