Use variables to create new hosts and groups in inventory for use in later plays of the same playbook. Takes variables so you can define the new hosts more fully.
parameter | required | default | choices | comments |
---|---|---|---|---|
groups |
no | The groups to add the hostname to, comma separated. aliases: groupname, group | ||
name |
yes | The hostname/ip of the host to add to the inventory, can include a colon and a port number. aliases: hostname, host |
# add host to group 'just_created' with variable foo=42 - add_host: name={{ ip_from_ec2 }} groups=just_created foo=42 # add a host with a non-standard port local to your machines - add_host: name={{ new_ip }}:{{ new_port }} # add a host alias that we reach through a tunnel - add_host: hostname={{ new_ip }} ansible_ssh_host={{ inventory_hostname }} ansible_ssh_port={{ new_port }}
Note
This module bypasses the play host loop and only runs once for all the hosts in the play, if you need it to iterate use a with_ directive.
