Interview › Infrastructure as Code (Terraform, Ansible)
How do you integrate Ansible into CI/CD and keep playbooks tested?
Infrastructure as Code (Terraform, Ansible) · Advanced level
Answer
I integrate Ansible into CI/CD by linting YAML and Ansible rules, testing roles with Molecule or ephemeral instances, running check mode where useful, scanning secrets, requiring code review, and using controlled credentials for production runs.
Technical explanation
Molecule can test roles with containers or VMs before merge.
CI should run syntax checks, linting, and targeted test scenarios.
Production execution should be auditable and use locked dependencies.
Prefer idempotent modules over shell so repeated runs are safe and change reporting is meaningful.
Separate reusable role logic from inventory-specific variables so the same automation works across environments.
Run lint, syntax checks, check mode where useful, and staged rollouts before production-wide changes.
Hands-on example
1. Add Ansible safety checks for: How do you integrate Ansible into CI/CD and keep playbooks tested?
2. CI commands:
ansible-playbook --syntax-check site.yml
ansible-lint .
yamllint .
ansible-playbook -i inventory/stage site.yml --check --diff
3. Avoid state: latest in production unless the rollout is explicitly an upgrade window. Prefer pinned versions or approved repositories:
- name: Install approved app version
ansible.builtin.package:
name: myapp-1.8.4
state: present
4. For mixed fleets, drive differences through group_vars, host_vars, and facts rather than copied playbooks.
5. Gate production runs behind review and record playbook version, inventory, operator, and output artifact.
