Let's assume (ha!) you've got a shell task that loops over a list of servers, and for any server with port 9090 open it prints "{{item}} running 9090" to its stdout. And that you register that to "fake" to match the code below.

---
- name: Working with registered data
  hosts: localhost
  gather_facts: no
  vars:
    fake:
      results:
        - item: server1
          stdout: ""
        - item: server2
          stdout: ""
        - item: server3
          stdout: "server3 running 9090\n"
        - item: server4
          stdout: ""
        - item: server5
          stdout: "server5 running 9090\n"
  tasks:
    - name: task1 pick the first server running 9090
      debug:
        msg: "{{ fake.results | selectattr('stdout', 'search', 'running 9090') | 
first }}"

    - name: task2 pick all servers running 9090
      debug:
        msg: "{{ fake.results | selectattr('stdout', 'search', 'running 9090') | 
map(attribute='item') }}"


That produces the following output:

TASK [task1 pick the first server running 9090] ********************************
task path: /home/utoddl/ansible/register-games.yml:19
ok: [localhost] => {
    "msg": "server3"
}

TASK [task2 pick all servers running 9090] *************************************
task path: /home/utoddl/ansible/register-games.yml:25
ok: [localhost] => {
    "msg": [
        "server3",
        "server5"
    ]
}

HI,
I have a list of servers that only part of them are running port 9090.
I need to create two tasks, each should loop the server's hostnames. the first task should define inside a register the first server hostname that was found running port 9090 , the second task should define in a register all server's hostnames that are running port 9090. If no server is running port 9090 the tasks should fail

I have nc installed on the server and i thought about using a shell with the command "nc -zv {{ item}} 9090

But I don't know how to filter the relevant answers

For example:
server1
server2
server3 running 9090
server4
server5 running 9090

- The first task should include in a register server 3 *or* server 5 hostname - The second task should include in a register server 3 *and *server 5 hostname
