Command Line Options

The following is the output from salt-lint --help, providing an overview of the basic command line options:

usage: salt-lint [-h] [--version] [-L] [-r RULESDIR] [-R] [-t TAGS] [-T] [-v] [-x SKIP_LIST] [--nocolor] [--force-color]
                 [--exclude EXCLUDE_PATHS] [--json] [--severity] [-c C]
                 files [files ...]

positional arguments:
  files                 One or more files or paths.

optional arguments:
  -h, --help            show this help message and exit
  --version             show program's version number and exit
  -L                    list all the rules
  -r RULESDIR           specify one or more rules directories using one or more -r arguments. Any -r flags
                        override the default rules in /path/to/salt-lint/saltlint/rules, unless -R is also used.
  -R                    Use default rules in /path/to/salt-lint/saltlint/rules in addition to any extra rules
                        directories specified with -r. There is no need to specify this if no -r flags are used.
  -t TAGS               only check rules whose id/tags match these values
  -T                    list all the tags
  -v                    Increase verbosity level
  -x SKIP_LIST          only check rules whose id/tags do not match these values
  --nocolor, --nocolour
                        disable colored output
  --force-color, --force-colour
                        Try force colored output (relying on salt's code)
  --exclude EXCLUDE_PATHS
                        path to directories or files to skip. This option is repeatable.
  --json                parse the output as JSON
  --severity            add the severity to the standard output
  -c C                  Specify configuration file to use. Defaults to ".salt-lint"

Linting Salt State files

It's important to note that salt-lint accepts a list of Salt State files or a list of directories.

Docker & Podman

salt-lint is available on Dockerhub.

Example usage:

docker run -v $(pwd):/data:ro --entrypoint=/bin/bash -it warpnetbv/salt-lint:latest -c 'find /data -type f -name "*.sls" -print0 | xargs -0 --no-run-if-empty salt-lint'

On a system with SELinux, change :ro to :Z. Example below uses podman:

podman run -v $(pwd):/data:Z --entrypoint=/bin/bash -it warpnetbv/salt-lint:latest -c 'find /data -type f -name "*.sls" -print0 | xargs -0 --no-run-if-empty salt-lint'

GitHub Action

Salt-lint is available on the GitHub marketplace as a GitHub Action. The salt-lint-action allows you to run salt-lint with no additional options.

To use the action simply add the following lines to your .github/workflows/main.yml.

on: [push]

    runs-on: ubuntu-latest
    name: Salt Lint Action
    - uses: actions/checkout@v1
    - name: Run salt-lint
      uses: roaldnefs/salt-lint-action@master
        ACTION_STATE_NAME: init.sls


Configuration File

Salt-lint supports local configuration via a .salt-lint configuration file. Salt-lint checks the working directory for the presence of this file and applies any configuration found there. The configuration file location can also be overridden via the -c path/to/file CLI flag.

If a value is provided on both the command line and via a configuration file, the values will be merged (if a list like exclude_paths), or the True value will be preferred, in the case of something like quiet.

The following values are supported, and function identically to their CLI counterparts:

  - exclude_this_file
  - exclude_this_directory/
  - exclude/this/sub-directory/
  - 207
  - 208
  - formatting
verbosity: 1
    ignore: |
    ignore: 'exclude_this_file.sls'
severity: True

Pre-commit Setup

To use salt-lint with pre-commit, just add the following to your local repo's .pre-commit-config.yaml file. Prior to version 0.12.0 of pre-commit the file was hooks.yaml (now .pre-commit-config.yaml).


# For use with pre-commit.
# See usage instructions at

-   repo:
    rev: v0.6.1
      - id: salt-lint

Optionally override the default file selection as follows:

      - id: salt-lint
        files: \.(sls|jinja|tmpl)$


Currently, there is a salt-lint plugin available for the following applications:

Application GitHub Link Store/Marketplace
Visual Studio Code warpnet/vscode-salt-lint VisualStudio Marketplace
Sublime Text warpnet/SublimeLinter-salt-lint Package Control
Vim (ALE plugin) dense-analysis/ale GitHub

Fix common issues

sed might be one of the better tools to fix common issues, as shown in commands below.

Note: these commands assume your current working directory is the salt (states) directory/repository.

Fix spacing around {{ var_name }}, eg. {{env}} --> {{ env }}:\ sed -i -E "s/\{\{\s?([^}]*[^} ])\s?\}\}/\{\{ \1 \}\}/g" $(find . -name '*.sls')

Make the dir_mode, file_mode and mode arguments in the desired syntax:\ sed -i -E "s/\b(dir_|file_|)mode: 0?([0-7]{3})/\1mode: '0\2'/" $(find . -name '*.sls')

Add quotes around numeric values that start with a 0:\ sed -i -E "s/\b(minute|hour): (0[0-7]?)\$/\1: '\2'/" $(find . -name '*.sls')


The project is heavily based on ansible-lint, with the modified work by Warpnet B.V.. ansible-lint was created by Will Thames and is now maintained as part of the Ansible by Red Hat project.
