If the only problem is with_items loop, replace it with: with_items: “{{ groups[‘local_vm’] }}” and you are good to go. Bare variables are not supported in with_ any more.
Ansible version 2 introduced a clean, official way to do this using delegated facts (see: http://docs.ansible.com/ansible/latest/playbooks_delegation.html#delegated-facts). when: hostvars[item][‘ansible_default_ipv4′] is not defined is a check to ensure you don’t check for facts in a host you already know the facts about — # This play will still work as intended if called with –limit “<host>” or … Read more
I think you might be just looking for the template lookup plugin: – set_fact: rendered_template: “{{ lookup(‘template’, ‘./template.j2’) }}” Usage example: template.j2 Hello {{ value_for_template }} playbook.yml — – hosts: localhost gather_facts: no connection: local vars: value_for_template: world tasks: – debug: var: rendered_template vars: rendered_template: “{{ lookup(‘template’, ‘./template.j2’) }}” The result: TASK [debug] ******************************************************************* ok: … Read more

The feature I’m describing below has been available since Ansible 2.6, but got a bugfix in v2.6.2 and another (minor) one in v2.7. To see a solution for older versions, see Paul’s answer. defaults/main/ Instead of creating defaults/main.yml, create a directory — defaults/main/ — and place all YAML files in there. defaults/main.yml → defaults/main/*.yml Ansible … Read more
Below should do the trick: – name: Install PHP Modules command: <command> with_dict: php_modules when: “‘batch’ in inventory_hostname” Note you’ll have a couple of skipped hosts during playbook run. inventory_hostname is one of Ansible’s “magic” variables: Additionally, inventory_hostname is the name of the hostname as configured in Ansible’s inventory host file. This can be useful … Read more
vars: HOST_COUNT: “{{ groups[‘maingroup’] | length }}”

Then if you want to use password authentication (do note the trailing comma): $ ansible-playbook playbook.yml -i localhost, -k In this case you also need sshpass. In case of public key authentication: $ ansible-playbook playbook.yml -i localhost, And … Read more
Faced the same issue in my project.
