如何使用Ansible一对一地部署在所有GCP实例上？

Question

I'm looking for a solution to deploy my code on all GCP instances of an instance group with ansible. I would list all instances of an instance group and deploy on them one by one to avoid service interruptions. Any idea ?

Thanks Thomas

I found the solution. You must add the "serial" key :

serial: <number>|"<number>%"

It sets how many hosts at a time to run at a time. The default is to run tasks on all of a play's machines at once.
