Ansible: deploy on multiple hosts in the same time

Question

Is it possible to run ansible playbook, which looks like this (it is an example from this site: http://docs.ansible.com/playbooks_roles.html):

- name: this i         


        

Answer 1

I played a long time with things like ls -1 | xargs -P to parallelize my playbooks runs. But to get a prettier display, and simplicity I wrote a simple Python tool to do it, ansible-parallel.

It goes like this:

pip install ansible-parallel
ansible-parallel *.yml

To answer precisely to the original question (how to run some tasks first, and the rest in parallel), it can be solved by removing the 3 includes and running:

ansible-playbook say_hi.yml
ansible-parallel load_balancers.yml webservers.yml dbservers.yml
