ansible: set fact with multiple values

[christia...@itsv.at]

i am writing an ansible role for setting some kind of "hostgroups" based on outputs from commands, path etc.. thing is one host can be a member of more then one of such groups, and there is the problem. how to i append multiple values to one particular fact, without using a gazillion of different variables for the groups, as this list might get really long. someone over there at stackoverflow mentioned the ternary filter, but i can not get my head around it, so some example code wold be really great.

best would be a list like this:

"itsv_hostgroup": {WBG,LNZ,...}

in this example the WBG value is overwritten by the VIE value in the end.

Ente

- shell: /usr/bin/uname -L | cut -d ' ' -f2
  register: itsv_lparname

- command: /usr/sbin/lsattr -El sys0 -a systemid -F value
  register: itsv_machine_serial

- set_fact:
        itsv_hostgroup: "LNZ"
        cacheable: true
  when: (itsv_machine_serial.stdout is match "IBM,02781A6BX") or
        (itsv_machine_serial.stdout is match "IBM,02781A6CX") or
        (itsv_machine_serial.stdout is match "IBM,02781A6DX")
- debug:
    var: itsv_hostgroup

- set_fact:
        itsv_hostgroup: "WBG"
        cacheable: true
  when: (itsv_machine_serial.stdout is match "IBM,022199BF7")
- debug:
    var: itsv_hostgroup

- set_fact:
        itsv_hostgroup: "GBG"
        cacheable: true
  when: (itsv_machine_serial.stdout is match "IBM,022199BB7")
- debug:
    var: itsv_hostgroup

- set_fact:
        itsv_hostgroup: "VIE"
        cacheable: true
  when: (itsv_machine_serial.stdout is match "IBM,022199BF7") or
        (itsv_machine_serial.stdout is match "022199BB7") or
        (itsv_machine_serial.stdout is match "IBM,02060CE6R")
- debug:
    var: itsv_hostgroup

Can you please stop hijacking other people thread and make your own.

This consider a very rude behavior.

Hopefully the moderators put you on moderation or ban you from the list.

Typo I guess list is is ["WBG","LNZ",...]

To add just do this to all of them

itsv_hostgroup: '{{ itsv_hostgroup | default([]) + ["LNZ"] }}'

The default([]) is there so it doesn't fail when itsv_hostgroup is not
defined, it will then be set to a empty list [].
And the rest just add a element to the list.

hmm....this seems a little bit sophisticated as the list of groups is much longer in reality as in my example code which has only 4, so this leads to a big variable mess. no way to reference the group names in any other way?

I don't think I understand the problem.
Your are writing gazillion variables and big variable mess, what do you
mean by that?

As I can see you only have to itsv_hostgroup and
itsv_machine_serial.stdout that's only two variable and very manageable
in Ansible.
