Variables

var (
	// IsLowercaseNumberHyphenNoStartHyphen is a regex for lowercase, numbers and hyphens that cannot start with a hyphen.

	IsLowercaseNumberHyphenNoStartHyphen = regexp.MustCompile(`^[a-z0-9][a-z0-9\-]*$`).MatchString
)

var ZarfSchema fs.ReadFileFS

ZarfSchema is exported so main.go can embed the schema file

Functions

func GroupFindingsByPath

func GroupFindingsByPath(findings []PackageFinding, packageName string) map[string][]PackageFinding

GroupFindingsByPath groups findings by their package path

func SupportedOS

func SupportedOS() []string

SupportedOS returns the supported operating systems.

The supported operating systems are: linux, darwin, windows.

An empty string signifies no OS restrictions.

func Validate

func Validate(ctx context.Context, baseDir, flavor string, setVariables map[string]string) error

Validate lints the given Zarf package

func ValidatePackage

func ValidatePackage(pkg v1alpha1.ZarfPackage) error

ValidatePackage runs all validation checks on the package.

Types

type LintError

type LintError struct {
	BaseDir     string
	PackageName string
	Findings    []PackageFinding
}

LintError represents an error containing lint findings.

func (*LintError) Error

func (e *LintError) Error() string

func (*LintError) OnlyWarnings

func (e *LintError) OnlyWarnings() bool

OnlyWarnings returns true if all findings have severity warning.

type PackageFinding

type PackageFinding struct {
	// YqPath is the path to the key where the error originated from, this is sometimes empty in the case of a general error
	YqPath      string
	Description string
	// Item is the value of a key that is causing an error, for example a bad image name
	Item string
	// PackageNameOverride shows the name of the package that the error originated from
	// If it is not set the base package will be used when displaying the error
	PackageNameOverride string
	// PackagePathOverride shows the path to the package that the error originated from
	// If it is not set the base package will be used when displaying the error
	PackagePathOverride string
	// Severity of finding.
	Severity Severity
}

PackageFinding is a struct that contains a finding about something wrong with a package

func CheckComponentValues

func CheckComponentValues(c v1alpha1.ZarfComponent, i int) []PackageFinding

CheckComponentValues runs lint rules validating values on component keys, should be run after templating

func ValidatePackageSchema

func ValidatePackageSchema(setVariables map[string]string) ([]PackageFinding, error)

ValidatePackageSchema checks the Zarf package in the current directory against the Zarf schema

func (PackageFinding) ItemizedDescription

func (f PackageFinding) ItemizedDescription() string

ItemizedDescription returns a string with the description and item if finding contains one.

type Severity

type Severity string

Severity is the type of finding.
