Playbook fails during instance creation task #9

Hello,

I followed the readme, but the playbook doesn't work.

Best regards, David

PS: "googleauth" doesn't exist on pip, pip suggests "google-auth"

davidaparicio commented 5 years ago

I found the solution in another project, in Ansible 2.7, we must add: 

metadata:
   istest: true

Source:

@rambleraptor : Will it be fixed in Ansible 2.8? How do you use it without these lines? Does exist an environment variable??

Hi David,

I encountered same problem and it seems that playbooks are not updated to current version of Ansible. Problem with gcp_compute_instance_group is this: "Unlike managed instance groups, you must create and add instances to an instance group manually". I am currently trying to switch to gce_mig, but that one requires instance templates :-)

Best Regards Peter
