Description:
ansibleparallel 2023.7.26
ansible-parallel
TL;DR:
pip install ansible-parallel
ansible-parallel *.yml
Executes multiple ansible playbooks in parallel.
For my usage, running sequentially (using a site.yml containing
multiple import_playbook) takes 30mn, running in parallel takes
10mn.
Usage
ansible-parallel runs like ansible-playbook but accepts multiple
playbooks. All remaining options are passed to ansible-playbook so
feel free to run ansible-parallel --check *.yml for example.
Example
It's easy to start:
$ ansible-parallel *.yml
When it runs, it display a live update of what's going on, one line per playbook:
web.yml: TASK [common : Configure Debian repositories] *****************************
gitlab.yml: TASK [common : Configure IP failover] *************************************
staging.yml: TASK [common : Configure Debian repositories] *****************************
dev.yml: Done.
And when it's done, it prints a full report like:
# Playbook playbook-webs.yml, ran in 123s
web1.meltygroup.com : ok=51 changed=0 unreachable=0 failed=0 skipped=12 rescued=0 ignored=0

Known alternatives
ansible-pull
ansible-parallel is only good if you want to keep the push behavior of
Ansible, but if you're here you may have a lot of playbooks, and
switching to
ansible-pull
with a proper reporting system like
ARA
xargs
A quick and dirty way of doing it in 3 lines of bash:
ls -1 *.yml | xargs -n1 -P16 sh -c 'ansible-playbook "$$0" > "$$0.log"' ||:
grep -B1 "^\(changed\|fatal\|failed\):" *.log
echo *.yml.log | xargs -n1 sed -n -e '/^PLAY RECAP/,$$p'
