Behind the scenes

How are identified applicable files

  • File extensions: .yml, .yaml
  • Detected file content (regex): apiVersion: tekton

How the linting is performed

  • tekton-lint is called one time by identified file (file CLI lint mode)

Example calls

tekton-lint myfile.yml

Help content

Usage:
tekton-lint <path-to-yaml-files>

Options:
$ tekton-lint --watch                # Run tekton-lint in watch mode
$ tekton-lint --version              # Show version number
$ tekton-lint --help                 # Show help
$ tekton-lint --color / --no-color   # Forcefully enable/disable colored output
$ tekton-lint --format               # Format output. Available formatters: vscode (default) | stylish | json
$ tekton-lint --quiet                # Report errors only - default: false
$ tekton-lint --max-warnings <Int>   # Number of warnings to trigger nonzero exit code - default: -1

Examples:
# Globstar matching
$ tekton-lint '**/*.yaml'

# Exact file path
$ tekton-lint my-pipeline.yaml my-task.yaml

# Multiple glob patterns
$ tekton-lint path/to/my/pipeline.yaml 'path/to/my/tasks/*.yaml'
