Hi #packer!
I am trying to learn more about Packer and Ansible. I think those too along
with Terraform, Bazel and jsonnet will be great to use!
With packer I am able to pass in a playbook.yml and an inventory file to
Ansible. However, I would like to be able to specify to ansible what host
it is currently running on, so it knows what section of the inventory file
to utilize.
I tried the `host_alias` parameter, but I then ended up with:
amazon-ebs: fatal: [master_host]: UNREACHABLE! => {"changed": false,
"msg": "Failed to connect to the host via ssh: ssh: Could not resolve
hostname master_host: nodename nor servname provided, or not known",
"unreachable": true}
Any ideas on what is the best way to tell Ansible what machine it is
provisioning through Packer?
Thank you!
Kevin
