Run a playbook with arbitrary host not in the inventory hosts list?

[Peter Loron]

Hello. I often want to run a playbook against an arbitrary host, sometimes one not defined in my inventory hosts file. Is there a way of specifying an arbitrary hostname or IP on the ansible-playbook command line to run things this way? It's a pain to have to edit the inventory each time I want to run something against a temporary machine (e.g. for testing).

Thanks.

-i 'myhost,' will define an inventory on the command line where you
can add any host/ip you want.

^ observe the , is needed even if only 1 host is defined to signify
this is a list and not a path to a file

Hi, Brian. I'm trying to run a playbook file which by definition must contain a "hosts" entry. When I run the ansible-playbook command with the "-i" flag, I get this:

> ansible-playbook -i '10.10.10.155,' -u root  do_base_packages.yaml


PLAY [dummy] ******************************************************************
skipping: no hosts matched

...where "dummy" is the hosts entry in the playbook file. The playbook file looks like this:

- hosts: dummy
  become: yes
  roles:
    - role: base
    - role: ntp
      ntp_server: [10.10.10.11, 10.10.10.12, 10.20.10.11]
      ntp_restrict:
        - "restrict 127.0.0.1"

How do I force a host on the command line without needing to define it in the playbook file or in the inventory? I'm on OSX 10.10.5 and Ansible 1.9.2.

Thanks!
