add_host - add a host (and alternatively a group) to the ansible-playbook in-memory inventory
Synopsis
- 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.
- This module is also supported for Windows targets.
Options
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 |
Examples
# 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 (Ansible <= 1.9) - add_host: hostname: "{{ new_ip }}" ansible_ssh_host: "{{ inventory_hostname }}" ansible_ssh_port: "{{ new_port }}" # add a host alias that we reach through a tunnel (Ansible >= 2.0) - add_host: hostname: "{{ new_ip }}" ansible_host: "{{ inventory_hostname }}" ansible_port: "{{ new_port }}" - name: Ensure inventory vars are set to the same value as the inventory_hostname has (close to pre 2.4 behaviour) add_host: hostname: charlie inventory_dir: "{{inventory_dir}}"
Notes
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.
- Windows targets are supported by this module.
- The alias ‘host’ of the parameter ‘name’ is only available on >=2.4
- Since Ansible version 2.4, the
inventory_dir
variable is now set toNone
instead of the ‘global inventory source’, because you can now have multiple sources. An example was added that shows how to partially restore the previous behaviour.
