Hello Everyone, i have a role “x” that uses two default vars: (roles/x/defaults/main.yml) server1var: server1 server2var: server2 based on these vars, tasks are executed on server1 or server2 now I have a playbook that executes some tasks and then includes role “x”: tasks: - name: fetch file from remote server fetch: src: … dest: … - name: copy file to remote server copy: src: … dest: … - include\_role: name: x In this playbook the two vars from /roles/x/defaults/main.yml are also present with different values. vars: server1var: server3 server2var: server4 Is it possible that the tasks executed by “include\_role” take the vars from the current playbook? All tasks that gets executed by the include\_role should be executed with the vars server1var: server3 server2var: server4 instead of the default vars: server1var: server1 server2var: server2 Can anyone tell me how i can do that? is it just like this maybe? - include\_role: name: x vars: server1var: server3 server2var: server4 What is the best way to this? Thank you for your time and help in advance. ---

Yes. It's possible. For example > cat roles/role\_x/defaults/main.yml server1var: server1 server2var: server2 > cat roles/role\_x/tasks/main.yml - debug:     var: server1var > cat playbook.yml - hosts: localhost   tasks:     - include\_role:         name: role\_x     - include\_role:         name: role\_x       vars:         server1var: server3 > ansible-playbook playbook.yml TASK [include\_role : role\_x] \*\*\*\* TASK [role\_x : debug] \*\*\*\* ok: [localhost] =\> { "server1var": "server1" } TASK [include\_role : role\_x] \*\*\*\* TASK [role\_x : debug] \*\*\*\* ok: [localhost] =\> { "server1var": "server3" } > Can anyone tell me how i can do that? > is it just like this maybe? > >     - include\_role: >         name: x >       vars: >         server1var: server3 >         server2var: server4 Yes. This is the best way. FWIW, there are issues.

Thank you very much for the help. I have found out that the problem is caused by a random generator. Its not the include\_role task itself (thats why I opened the question in first place) I have two lists and building a new list excluding the items from list1 (which is something like “server1”, “server2”…) vars: list1: - “{{file\_content.server1var}}” - “{{file\_content.server2var}}” list2: - server1 - server2 - server3 - server4 - server5 - server6 tasks: - name: generate newlist based on difference between list1 and list2 set\_fact: newlist: “{{ list2 | difference(list1) }}” - name: set fact random2 set\_fact: randomserver: “{{ newlist | random }}” ##This for example shows me server2 when i run the play one time### - name: show randomnode debug: msg: “{{randomnode}}” … ##Now im using that randomnode variable for the include\_role## - include\_role: name: x vars: server1var: server3 server2var: “{{randomserver}}” This is the task in role “x”: - name: ping the servers ping: when: inventory\_hostname == server1var or inventory\_hostname == server2var ###Now im expecting that “server2var” will be “server2”, but its kinda random what happens there### ###For example: sometimes its get executed on 4 servers, 3 servers, 2 servers, 1 server. The only Server that is consistent is server1var (whhich is “server1”)### Maybe you have an idea what might cause that problem? I saw in your github examples, that you already used random filter. ---

Well I actually found the problem. I had to set run\_once:yes in the following part: - name: set fact random2 set\_fact: randomserver: “{{ newlist | random}}” run\_once: yes Now I get the correct Servers Anyway, Thank you for your help Mr. Botka.
