I am curious if there is any mechanism to perform synchronous tasks among a group of nodes (or nodes in a role, etc.)
There is one example online to perform rolling updates to a group of web servers, one at a time. This makes perfect sense, since in this case you don't want to shut down all of them to keep the service up. But in another scenario, where I need to shut down all the service nodes, upgrade database schema, upgrade software code, and then restart the nodes.. So, I want to have a play book that can do: - stop all nodes in a group/role - perform db migration - perform software upgrade for all nodes - start service one by one Is there a way to do this?
