question about loop/with_items

[Edmund Cheng]

hi,

say i have in hosts file 2 nodes.

[nodes]

server1

server2

in a playbook, we do some loop for tasks.

- hosts: nodes

  <some task>

  with_items : ['apple','banana']

ansible will run it like in the below order:

server1 : apple

server2: apple

server1: banana

server2: banana

what if i want to run in this order?

server1: apple

server1: banana

server2: apple

server2: banana

Is there a good approach for this?

Check out serial, serial: 1 on the play will give you that.

Hey Kai,

thanks.. do you know why if its 1 server at a time(serial: 1), the play will behave this way?

The documentation explains this pretty well
