That was brilliant Kai, it worked for me very well.
To add some more info, i did it like this:
Playbook:
- template: src=/opt/report.txt dest=/opt/reports/linux_report.txt
delegate_to: 127.0.0.1
run_once: true
Report.txt
List of linux hosts checked:
{% for i in play_hosts %}
{{ i }}: Username - {{ hostvars[i].ansible_user }}, Hostname - {{
hostvars[i].ansible_host }}
{% endfor %}
Check if OS version is {{linuxDistribution}} version
{{linuxDistributionVersion}}
{% for i in play_hosts %}
{% if linuxDistribution == hostvars[i].ansible_distribution and
linuxDistributionVersion == hostvars[i].ansible_distribution_version %}
{{ i }}: Success - OS version - {{linuxDistribution}} version
{{linuxDistributionVersion}}
{% else %}
{{ i }}: Failed - Found OS version {{ hostvars[i].ansible_distribution }}
version {{hostvars[i].ansible_distribution_version }}against required
{{linuxDistribution}} version {{linuxDistributionVersion}}
{% endif %}
{% endfor %}
