How to specifying multiple groups in a playbook hosts specification?

By design, Ansible executes just one play at a time. Your playbook consists of two plays (the two items in the root-level YAML list defined by the playbook file).

Method 1
The following patterns address one or more groups. Groups separated by a colon indicate an “OR” configuration. This means the host may be in either one group or the other:

Method 2
You can exclude groups as well, for instance, all machines must be in the group webservers but not in the group phoenix:

Method 3
You can also specify the intersection of two groups. This would mean the hosts must be in the group webservers and the host must also be in the group staging:

Method 4
You can also specify the intersection of two groups. This would mean the hosts must be in the group webservers and the host must also be in the group staging: The below configuration means “all machines in the groups ‘webservers’ and ‘dbservers’ are to be managed if they are in the group ‘staging’ also, but the machines are not to be managed if they are in the group ‘phoenix’ … whew!

Method 5
You can also use variables if you want to pass some group specifiers via the “-e” argument to ansible-playbook, but this is uncommonly used:
