Learn how to optimize Ansible playbooks for better performance. Parallel execution, caching, and best practices.
Optimized playbooks run faster and are more maintainable. This guide covers optimization techniques.
# ansible.cfg
[defaults]
forks = 10
host_key_checking = False
# Playbook
- hosts: all
serial: 5 # Run on 5 hosts at a time
tasks:
- name: Install packages
apt:
name: "{{ item }}"
loop:
- nginx
- python3
# ansible.cfg
[defaults]
fact_caching = jsonfile
fact_caching_connection = /tmp/ansible_facts
fact_caching_timeout = 3600
# Use modules instead of shell
- name: Install package
apt:
name: nginx
state: present
# Instead of: shell: apt-get install nginx
# Use handlers
handlers:
- name: restart nginx
systemd:
name: nginx
state: restarted
tasks:
- name: Update config
template:
src: nginx.conf.j2
dest: /etc/nginx/nginx.conf
notify: restart nginx
Optimize playbooks by using modules, enabling caching, and running tasks in parallel for better performance.
For Ansible Playbook Optimization: Writing Efficient Playbooks, define pre-deploy checks, rollout gates, and rollback triggers before release. Track p95 latency, error rate, and cost per request for at least 24 hours after deployment. If the trend regresses from baseline, revert quickly and document the decision in the runbook.
Keep the operating model simple under pressure: one owner per change, one decision channel, and clear stop conditions. Review alert quality regularly to remove noise and ensure on-call engineers can distinguish urgent failures from routine variance.
Repeatability is the goal. Convert successful interventions into standard operating procedures and version them in the repository so future responders can execute the same flow without ambiguity.
