Functions

func DetectSyntax

func DetectSyntax(r io.Reader) (string, string, bool)

func ParseDirectives(r io.Reader) map[string]string

func WithInternalName(name string, a ...interface{}) llb.ConstraintsOpt

Types

type ConvertOpt

type ConvertOpt struct {
	Target       string
	MetaResolver llb.ImageMetaResolver
	BuildArgs    map[string]string
	Labels       map[string]string
	SessionID    string
	BuildContext *llb.State
	Excludes     []string
	// IgnoreCache contains names of the stages that should not use build cache.
	// Empty slice means ignore cache for all stages. Nil doesn't disable cache.
	IgnoreCache []string
	// CacheIDNamespace scopes the IDs for different cache mounts
	CacheIDNamespace string
	ImageResolveMode llb.ResolveMode
	TargetPlatform   *specs.Platform
	BuildPlatforms   []specs.Platform
	PrefixPlatform   bool
	ExtraHosts       []llb.HostIP
	ForceNetMode     pb.NetMode
}

type HealthConfig

type HealthConfig struct {
	// Test is the test to perform to check that the container is healthy.
	// An empty slice means to inherit the default.
	// The options are:
	// {} : inherit healthcheck
	// {"NONE"} : disable healthcheck
	// {"CMD", args...} : exec arguments directly
	// {"CMD-SHELL", command} : run command with system's default shell
	Test []string `json:",omitempty"`

	// Zero means to inherit. Durations are expressed as integer nanoseconds.
	Interval    time.Duration `json:",omitempty"` // Interval is the time to wait between checks.
	Timeout     time.Duration `json:",omitempty"` // Timeout is the time to wait before considering the check to have hung.
	StartPeriod time.Duration `json:",omitempty"` // The start period for the container to initialize before the retries starts to count down.

	// Retries is the number of consecutive failures needed to consider a container as unhealthy.
	// Zero means inherit.
	Retries int `json:",omitempty"`
}

HealthConfig holds configuration settings for the HEALTHCHECK feature.

type Image

type Image struct {
	specs.Image

	// Config defines the execution parameters which should be used as a base when running a container using the image.
	Config ImageConfig `json:"config,omitempty"`
}

Image is the JSON structure which describes some basic information about the image. This provides the `application/vnd.oci.image.config.v1+json` mediatype when marshalled to JSON.

func Dockerfile2LLB

func Dockerfile2LLB(ctx context.Context, dt []byte, opt ConvertOpt) (*llb.State, *Image, error)

type ImageConfig

type ImageConfig struct {
	specs.ImageConfig

	Healthcheck *HealthConfig `json:",omitempty"` // Healthcheck describes how to check the container is healthy
	ArgsEscaped bool          `json:",omitempty"` // True if command is already escaped (Windows specific)

	//	NetworkDisabled bool                `json:",omitempty"` // Is network disabled
	//	MacAddress      string              `json:",omitempty"` // Mac Address of the container
	OnBuild     []string          // ONBUILD metadata that were defined on the image Dockerfile
	StopTimeout *int              `json:",omitempty"` // Timeout (in seconds) to stop a container
	Shell       strslice.StrSlice `json:",omitempty"` // Shell for shell-form of RUN, CMD, ENTRYPOINT
