You need to create a static `inventory` file that corresponds to your `Vagrantfile` machine definitions:

```
controller ansible_connection=local
node1 ansible_host=172.17.177.21 ansible_ssh_private_key_file=/vagrant/.vagrant/machines/node1/virtualbox/private_key
node2 ansible_host=172.17.177.22 ansible_ssh_private_key_file=/vagrant/.vagrant/machines/node2/virtualbox/private_key

[nodes]
node[1:2]
```

And finally, you also have to create an [`ansible.cfg` file](https://docs.ansible.com/intro_configuration.html#openssh-specific-settings) to fully disable SSH host key checking. More SSH configurations can be added to the `ssh_args` parameter (e.g. agent forwarding, etc.)

```
[defaults]
host_key_checking = no

[ssh_connection]
ssh_args = -o ControlMaster=auto -o ControlPersist=60s -o UserKnownHostsFile=/dev/null -o IdentitiesOnly=yes
```
