uses: huntridge-labs/argus/.github/actions/linter-dockerfile@1.12.2

Validate Dockerfiles using Hadolint.

Overview

This action checks Dockerfiles for best practices and common issues. It uploads results as artifacts that can be aggregated by the linting summary action.

Usage

- name: Checkout code
  uses: actions/checkout@v6

- name: Run Dockerfile linting
  uses: huntridge-labs/argus/.github/actions/linter-dockerfile@1.12.2
  with:
    fail_on_issues: false

Inputs

Input	Description	Required	Default
fail_on_issues	Fail the job if issues are found	No	false
fail_on_tool_error	Fail the job when the linter tool itself errors (a crash — argus exit code 2), independent of fail_on_issues. Tool errors are always surfaced in the job log, status table, and PR comment; this only makes them block.	No	false
paths	Paths to search for Dockerfiles (space-separated)	No	.
config_file	Path to Hadolint configuration file	No	''
ignore_rules	Hadolint rules to ignore (comma-separated)	No	''

Outputs

Output	Description
issues_count	Number of linting issues found
tool_status	Whether the linter tool ran cleanly: ok, or error when the tool itself crashed (argus exit code 2).
