	Host(context.Context) (string, error)                           // get host where the container port is exposed
	MappedPort(context.Context, nat.Port) (nat.Port, error)         // get externally mapped port for a container port
	Ports(context.Context) (nat.PortMap, error)                     // get all exposed ports
	SessionID() string                                              // get session id
	Start(context.Context) error                                    // start the container
	Terminate(context.Context) error                                // terminate the container
	Logs(context.Context) (io.ReadCloser, error)                    // Get logs of the container

}

ContainerProvider allows the creation of containers on an arbitrary system

type ContainerRequest ¶

type ContainerRequest struct {
	Image        string
	Env          map[string]string

	Labels       map[string]string
	BindMounts   map[string]string
	RegistryCred string
	WaitingFor   wait.Strategy
	Name         string // for specifying container name
	Privileged   bool   // for starting privileged container

	SkipReaper bool // indicates whether we skip setting up a reaper for this
}

ContainerRequest represents the parameters used to get a running container

type DeprecatedContainer ¶

	// Container ID from Docker
	ID         string
	WaitingFor wait.Strategy
	// contains filtered or unexported fields
}

DockerContainer represents a container started using Docker

GetIPAddress is deprecated and kept for backwards compat Deprecated: Use IPAddress()

func (*DockerContainer) Host ¶

func (c *DockerContainer) Host(ctx context.Context) (string, error)

}

GenericContainerRequest represents parameters to a generic container

type ProviderType ¶

type ProviderType int

ProviderType is an enum for the possible providers

const (
	ProviderDocker ProviderType = iota // Docker is default = 0
)

possible provider types

func (ProviderType) GetProvider ¶

type ReaperProvider ¶

type ReaperProvider interface {
