| + | ==== How to Create and Use Custom Facts in Ansible ==== | ||
| + | |||
| + | Custom facts (local facts) are the variables which are declared on ansible managed host. Custom facts are declared in ini or json file in the /etc/ansible/facts.d directory on managed host. File names of custom facts must have .fact extension. | ||
| + | |||
| + | https://www.linuxtechi.com/create-use-custom-facts-in-ansible/ | ||
| + | |||
| + | |||
| + | Get the value of a variable Ex: var1 | ||
| + | <cli prompt='#'> | ||
| + | opensuse:~ # ansible -i "node2," all -e "var1=toto" -m debug -a 'msg={{ var1 }}' | ||
| + | </cli> | ||
| + | |||
| + | ===== Ansible inventory ===== | ||
| + | |||
| + | <cli prompt='$'> | ||
| + | $ ansible --version | grep 'config file' | ||
| + | config file = /home/tux/.ansible.cfg | ||
| + | $ ansible-config dump --only-changed | ||
| + | DEFAULT_BECOME(/home/tux/.ansible.cfg) = True | ||
| + | DEFAULT_BECOME_METHOD(/home/tux/.ansible.cfg) = sudo | ||
| + | DEFAULT_HOST_LIST(/home/tux/.ansible.cfg) = ['/home/tux/ | ||
| + | inventory'] | ||
| + | DEFAULT_REMOTE_USER(/home/tux/.ansible.cfg) = ansible | ||
| + | </cli> | ||
| + | |||
| + | List all hosts, use the keyword **all**. To specify all host not in a group use **ungrouped** | ||
| + | <cli prompt='$'> | ||
| + | $ ansible all --list-hosts | ||
| + | hosts (21): | ||
| + | green.example.com | ||
| + | blue.example.com | ||
