Run Ansible adhoc commands in sequence

Question

I'm trying to run ansible adhoc commands on an ec2 instance on aws sequentially but I think its getting executed parallelly.

Something like this:

ansible aws -a "hostname"
ec2 | SUCCESS | rc=0 >>
ip-172-31-36-255

ec3 | SUCCESS | rc=0 >>
ip-172-31-45-174

ansible aws -a "hostname"
ec3 | SUCCESS | rc=0 >>
ip-172-31-45-174

ec2 | SUCCESS | rc=0 >>
ip-172-31-36-255

Hey @Thomas, by default ansible runs these commands parellely. If you want it to be executed sequencially then you need to explicitly mention it using --fork.

On adhoc command:

ansible aws -a "hostname" --forks=1

Inside the playbook:

- hosts: aws
  become: yes
  gather_facts: yes
  serial: 1
  tasks:
    - your tasks
