Types

type BuildOptions

type BuildOptions struct {
	// Tags for the Docker image
	Tags []string

	// Build args to pass the 'docker build' command
	BuildArgs []string

	// Custom CLI options that will be passed as-is to the 'docker build' command. This is an "escape hatch" that allows
	// Terratest to not have to support every single command-line option offered by the 'docker build' command, and
	// solely focus on the most important ones.
	OtherOptions []string

	// Set a logger that should be used. See the logger package for more info.
	Logger *logger.Logger
}

BuildOptions defines options that can be passed to the 'docker build' command.

type ContainerInspect

type ContainerInspect struct {
	// ID of the inspected container
	ID string

	// Name of the inspected container
	Name string

	// time.Time that the container was created
	Created time.Time

	// String representing the container's status
	Status string

	// Whether the container is currently running or not
	Running bool

	// Container's exit code
	ExitCode uint8

	// String with the container's error message, if there is any
	Error string

	// Ports exposed by the container
	Ports []Port

	// Volume bindings made to the container
	Binds []VolumeBind

	// Health check
	Health HealthCheck
}

ContainerInspect defines the output of the Inspect method, with the options returned by 'docker inspect' converted into a more friendly and testable interface

func Inspect

func Inspect(t *testing.T, id string) *ContainerInspect

Inspect runs the 'docker inspect {container id}' command and returns a ContainerInspect struct, converted from the output JSON, along with any errors

func InspectE

func InspectE(t *testing.T, id string) (*ContainerInspect, error)

InspectE runs the 'docker inspect {container id}' command and returns a ContainerInspect struct, converted from the output JSON, along with any errors

type HealthCheck

type HealthCheck struct {
	// Health check status
	Status string

	// Current count of failing health checks
	FailingStreak uint8

	// Log of failures
	Log []HealthLog
}

HealthCheck represents the current health history of the container

type HealthLog

type HealthLog struct {
	// Start time of health check
	Start string

	// End time of health check
	End string

	// Exit code of health check
	ExitCode uint8
