[Question] How to implement `contains` in hostgroup assign where clause

[lutin-malin]

Question

Hello,

I'm trying to replicate a manually made hostgroup configuration like below :

using the icinga_hostgroup module.

I've tried two notations, 'contains' and 'in' and none is rendering properly.

contains notation :

- name:  Icinga configure hostgroups
  telekom_mms.icinga_director.icinga_hostgroup:
    object_name: custom_hostgroup
    assign_filter: 'host.vars.custom_field contains "my_var_value"'

Deployment fails

[2025-03-07 11:04:43 +0100] critical/config: Error: syntax error, unexpected T_IDENTIFIER, expecting '}'
Location: in [[stage]/zones.d/director-global/hostgroups.conf]: 30:35-30:42
[[stage]/zones.d/director-global/hostgroups.conf]: object HostGroup "custom_hostgroup" {
[[stage]/zones.d/director-global/hostgroups.conf]:     assign where host.vars.custom_field  contains my_var_value == 1
                                                                                                                                             ^^^^^^^^

we can see that the assign criteria is suffixed with == 1, which is obviously invalid

note : playing with postman targeting directly the director API, i can confirm that submitting the contains syntax as above is converted by the API itself to var contains value == 1, so issue should not be related to the ansible module icinga_hostgroup

in notation

- name:  Icinga configure hostgroups
  telekom_mms.icinga_director.icinga_hostgroup:
    object_name: custom_hostgroup
    assign_filter: '"my_var_value" in host.vars.custom_field'

which ends up in
` assign where null in 1``

[2025-03-06 18:29:23 +0100] critical/config: Error: Invalid right side argument for 'in' operator: 1
Location: in [[stage]/zones.d/director-global/hostgroups.conf: 30:18-30:26
[[stage]/zones.d/director-global/hostgroups.conf]: 
[[stage]/zones.d/director-global/hostgroups.conf]: object HostGroup "custom_hostgroup" {
[[stage]/zones.d/director-global/hostgroups.conf]:     assign where null in 1
                                                                                                 ^^^^^^^^^

Could you help me to achieve the proper assign where clause ?

Hi @lutin-malin,
try with the assign filter written with the equal sign, applied to your case is like this:

- name:  Icinga configure hostgroups
  telekom_mms.icinga_director.icinga_hostgroup:
    object_name: custom_hostgroup
    assign_filter: '"my_var_value"=host.vars.custom_field'

It worked for me in service_apply and in service_set
Let me know if it works for you too
