ansible Jinja template loop - ansible

Question

I'm attempting to loop through a registered variable in a Jinja template via an Ansible playbook. Here is my task:
- name: Check if ports are open | inventory ports
wait_for:
host: "{{ item.name }}"
port: "{{ item.port }}"
state: started
delay: 0
timeout: 5
ignore_errors: true
loop: "{{ server_facts.server_port|default (server_port) }}"
register: server_port_check
Then here is the output:
"server_port_check.results": [
{
"state": "started",
"port": 636,
"search_regex": null,
"match_groups": [],
"match_groupdict": {},
"path": null,
"elapsed": 0,
"invocation": {
"module_args": {
"host": "dc.domain.com",
"port": 636,
"state": "started",
"delay": 0,
"timeout": 5,
"connect_timeout": 5,
"active_connection_states": [
"ESTABLISHED",
"FIN_WAIT1",
"FIN_WAIT2",
"SYN_RECV",
"SYN_SENT",
"TIME_WAIT"
],
"sleep": 1,
"path": null,
"search_regex": null,
"exclude_hosts": null,
"msg": null
}
},
"failed": false,
"changed": false,
"item": {
"name": "dc.domain.com",
"port": 636
},
"ansible_loop_var": "item"
},
{
"state": "started",
"port": 4505,
"search_regex": null,
"match_groups": [],
"match_groupdict": {},
"path": null,
"elapsed": 0,
"invocation": {
"module_args": {
"host": "server01",
"port": 4505,
"state": "started",
"delay": 0,
"timeout": 5,
"connect_timeout": 5,
"active_connection_states": [
"ESTABLISHED",
"FIN_WAIT1",
"FIN_WAIT2",
"SYN_RECV",
"SYN_SENT",
"TIME_WAIT"
],
"sleep": 1,
"path": null,
"search_regex": null,
"exclude_hosts": null,
"msg": null
}
},
"failed": false,
"changed": false,
"item": {
"name": "server01",
"port": 4505
},
"ansible_loop_var": "item"
}
],
"_ansible_verbose_always": true,
"_ansible_no_log": false,
"changed": false
}
When I'm able to grab what I want with the following task:
- name: debugging
debug:
msg:
- "{{ server_port_check.results.0.item.name }}"
- "{{ server_port_check.results.0.port }}"
- "{{ server_port_check.results.0.state }}"
How do I loop over this in a template. I've been doing the following (or different variations):
{% for results in server_port_check.results %}
Host: {{ item.name }}
Port: {{ port }}
Status: {{ state }}
{% endfor %}
The playbook fails with
The task includes an option with an undefined variable

Answer 1

The item of your for loop, is the .0 of your debug task.
So:
{% for result in server_port_check.results %}
Host: {{ result.item.name }}
Port: {{ result.port }}
Status: {{ result.state }}
{% endfor %}
