# Installing

Install Ansible-lint to apply rules and follow best practices with your
automation content.

!!! note

    Ansible-lint does not currently support installation on Windows systems.

!!! warning

    Ansible-lint does not support any installation methods that are not mentioned in
    this document. Before raising any bugs related to installation, review all of
    the following details:

    - You should use the installation methods outlined in this document only.
    - You should upgrade the Python installer (`pip` or `pipx`) to the latest
      version available from pypi.org. If you use a system package manager, you
      will need to upgrade the installer to a newer version.
    - If you are installing from a git zip archive, which is not supported but
      should work, ensure you use the main branch and the latest version of pip and
      setuptools.
    - If you are installing Ansible-lint within a container or system package, you
      should not report the issue here. Contact the relevant container or package
      provider instead.
    - If you are using [poetry](https://python-poetry.org/), read this
      [discussion](https://github.com/ansible/ansible-lint/discussions/2820#discussioncomment-4400380).

    Pull requests to improve installation instructions are welcome. Any new issues
    related to the installation will be closed and locked.

For a container image, we recommend using
[creator-ee](https://github.com/ansible/creator-ee/) which includes
`ansible-dev-tools` (it combines critical Ansible development packages into a
unified Python package). If you have a use case that the `creator-ee` container
doesn't satisfy, please contact the team through the
[discussion](https://github.com/ansible/ansible-lint/discussions) forum.

You can also run Ansible-lint on your source code with the
[Ansible-lint GitHub action](https://github.com/marketplace/actions/run-ansible-lint)
instead of installing it directly.

## Installing the latest version

{{ install_from_adt("ansible-lint") }}

You can install the most recent version of Ansible-lint with the [pip3] or
[pipx] Python package manager. Use [pipx] to isolate Ansible-lint from your
current Python environment as an alternative to creating a virtual environment.

```bash
# This also installs ansible-core if it is not already installed
pip3 install ansible-lint
```

!!! note

    If you want to install the exact versions of all dependencies that were used to
    test a specific version of ansible-lint, you can add `lock` extra. This will
    only work with Python 3.10 or newer. Do this only inside a virtual environment.

    ```bash
    pip3 install "ansible-lint[lock]"
    ```

## Installing on Fedora and RHEL

You can install Ansible-lint on Fedora, or Red Hat Enterprise Linux (RHEL) with
the `dnf` package manager.

```bash
dnf install ansible-lint
```

!!! note

    On RHEL, `ansible-lint` package is part of "Red Hat Ansible Automation
    Platform" subscription, which needs to be activated.

## Installing from source code

**Note**: `pip>=22.3.1` is required for installation from the source repository.
Please consult the [PyPA User Guide] to learn more about managing Pip versions.

```bash
pip3 install git+https://github.com/ansible/ansible-lint
```

## Installing Ansible Lint as a GitHub Action

To use the action simply create a file `.github/workflows/ansible-lint.yml` with
content similar to the example below:

```yaml
# .github/workflows/ansible-lint.yml
name: ansible-lint
on:
  pull_request:
    branches: ["stable", "release/v*"]
jobs:
  build:
    name: Ansible Lint # Naming the build is important to use it as a status check
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Run ansible-lint
        uses: ansible/ansible-lint@main
        # optional (see below):
        with:
          args: ""
          setup_python: "true"
          working_directory: ""
          requirements_file: ""
```

All the arguments are optional and most users should not need them:

- `args`: Arguments to be passed to ansible-lint command.
- `setup_python`: If python should be installed. Default is `true`.
- `working_directory`: The directory where to run ansible-lint from. Default is
  `github.workspace`. That might be needed if you want to lint only a subset of
  your repository.
- `requirements_file`: Path to the requirements.yml file to install role and
  collection dependencies.

Due to limitations on how GitHub Actions are processing arguments, we do not
plan to provide extra options. You will have to make use of
[ansible-lint own configuration file](https://ansible.readthedocs.io/projects/lint/configuring/)
to alter its behavior.

To also enable [dependabot][dependabot] automatic updates, the newer versions of
ansible-lint action you should create a file similar to
[.github/dependabot.yml][.github/dependabot.yml]

[.github/dependabot.yml]:
  https://github.com/ansible/ansible-lint/blob/main/.github/dependabot.yml#L13-L19
