A Linter for Your Playbooks
ansible-lint reads your playbooks and roles, then flags risky patterns and style issues before they ever touch a server. 🔍
Run It Locally First
Point ansible-lint at a file or a whole project and it returns a list of findings, each tied to a rule and a line.
ansible-lint playbook.yml
ansible-lint .Rules Encode Best Practice
Each rule captures one community best practice, like avoiding bare command when a real module exists.
The Exit Code Is the Gate
The real power: ansible-lint returns a non-zero exit code when it finds problems, which lets CI stop the build automatically.
Profiles Set the Bar
A profile picks how strict you are, from min up to production, so teams can raise the bar over time.
ansible-lint --profile productionConfigure with .ansible-lint
Drop an .ansible-lint file at your project root to set the profile and tune rules in one shared place.
profile: production
exclude_paths:
- .cache/Skip a Rule on Purpose
List rule names under skip_list when a warning truly does not apply, so the team agrees to ignore it on purpose.
skip_list:
- yaml[line-length]
- no-changed-whenInline Noqa for One Line
Need to silence just one task? Add a noqa comment on that line instead of disabling the rule everywhere.
- command: /usr/bin/make # noqa: no-changed-whenIt Lints YAML Too
ansible-lint also runs yamllint under the hood, so bad indentation and trailing spaces get caught alongside Ansible rules.
Pin It for Reproducibility
Pin an ansible-lint version in your requirements so every developer and the CI runner judge the code by the same rules.
