Types

type Dockerfile

type Dockerfile struct {
	ExposedPorts []portConfig
	HealthCheck  *HealthCheck
	// contains filtered or unexported fields
}

Dockerfile represents a parsed Dockerfile.

func New

func New(fs afero.Fs, path string) *Dockerfile

New returns an empty Dockerfile.

func (*Dockerfile) GetExposedPorts

func (df *Dockerfile) GetExposedPorts() ([]uint16, error)

GetExposedPorts returns a uint16 slice of exposed ports found in the Dockerfile.

func (*Dockerfile) GetHealthCheck

func (df *Dockerfile) GetHealthCheck() (*HealthCheck, error)

GetHealthCheck parses the HEALTHCHECK instruction from the Dockerfile and returns it. If the HEALTHCHECK is NONE or there is no instruction, returns nil.

type ErrInvalidPort

type ErrInvalidPort struct {
	Match string
}

ErrInvalidPort means that while there was a port provided, it was out of bounds or unparseable

func (ErrInvalidPort) Error

func (e ErrInvalidPort) Error() string

type ErrNoExpose

type ErrNoExpose struct {
	Dockerfile string
}

ErrNoExpose means there were no documented EXPOSE statements in the given dockerfile.

func (ErrNoExpose) Error

func (e ErrNoExpose) Error() string

type HealthCheck

type HealthCheck struct {
	Interval    time.Duration
	Timeout     time.Duration
	StartPeriod time.Duration
	Retries     int
	Cmd         []string
}

HealthCheck represents health check options for a Dockerfile.
