Run simultaneously in all servers

Is there a way that I can run a playbook that lets say patches where it will patch all hosts in a group simultaneously instead of running systematically through each individual server?

Thanks!

I bet there are better ways but what would stop you from forking a
bunch of instances?

Hi Chris,

By default, ansible will run 5 hosts in parallel at at time

https://docs.ansible.com/ansible/2.5/reference_appendices/config.html#default-forks

DEFAULT_FORKS

Description:

Maximum number of forks Ansible will use to execute tasks on target hosts.

Type:

integer

Default:

5

Ini Section:

defaults

Ini Key:

forks

Environment:

ANSIBLE_FORKS

If you want to run all the hosts in parallel, I suppose you can add the following to your ansible.cfg

[default]
forks=999

Could someone please share an Ansible Playbook that would update/upgrade a group of Ubuntu servers.

Thanks…

Very cool! Thanks! Clearly, I’m still learning ansible.
