when condition on a variable starting with a string value

[fanvalt]

Hello,

Actually I wrote my playbook this way to set values id the dual variable is the string value SRV:

   - set_fact:

      distrib: "{{ distribsrv }}"

      Directoryname: "{{ Directorysrv }}"

     when: dual == 'SRV'

I would like to modify the when condition to run it when dual == 'SRV1', "SRV2' ... etc, is there a way to do a when condition : when : dual like 'SRV*' ?

[fanvalt]

I wrote this:

  vars:

   services:

     - SRV

     - SRV[1:99]

   - set_fact:

      distrib: "{{ distribsrv }}"

     when: dual in services

but dual is SRV2 and the set_fact module has been ignored

[fanvalt]

if I write this, i do not get a variable list:

   - set_fact:

       services: "{{ services + item }}"

     with_sequence: count=99

   - debug: msg="sequence {{ services }}"

ok: [SRV1] => {

    "msg": "sequence SRV123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081828384858687888990919293949596979899"

}

the result expected is SRV1, SRV2, SRV3 ....

My issue is: I would like to run a task when a variable start with 'SRV' (srv1, SRV2 ...) ad I don't know how to write the condition: when: dual like 'SRV*'

I know this is weird, but can't think of something better:

- set_fact:
distrib: "{{ distribsrv }}"
Directoryname: "{{ Directorysrv }}"

when: dual | regex_replace( '^SRV.*', 'True') | bool

Cheers,
Marko

thank you I will have a look at your solution, I finally found this way to proceed otherwise:

   - set_fact:

       services: "{{ services }} + SRV{{item }}"

     with_sequence: count=5

   - set_fact:

      distrib: "{{ distribsrv }}"

     when: dual in services

TASK [debug] *******************************************************************

ok: [SRV1] => {

    "msg": "sequence SRV + SRV1 + SRV2 + SRV3 + SRV4 + SRV5"

}

Thanks a lot Marko, I used your syntax:

  dual|regex_replace('^SRV(.*)', 'True')

Did you try the following?

In your case this should be:

when: dual | search("SRV")
