I’m struggling with hosts that belong to multiple host groups and have different aliases. The problem i’m facing is, that if i try to execute a task on group “all\_hosts” where each group belongs to, the task is executed for each alias and not on a ansible\_host basis.

I expect that the task is only executed once for the host. Independent of the alias.

The inventory i’m using looks like this:

[all\_hosts:children]  
group1  
group2

[group1]  
host-alias-1-group-1 ansible\_host=host-1

[group2]  
host-alias-1-group-2 ansible\_host=host-1

I can create the all\_hosts group like this:

[all\_hosts:children]  
host-alias-1-group-all ansible\_host=host-1

…but that seems like a workaround. Any advice would be appreciated.
