Types

type Client

type Client interface {
	dockerclient.ContainerAPIClient
	dockerclient.ImageAPIClient
}

Client specifies the Docker client API interface required by docker driver

type Driver

type Driver struct {
	// ExternalHost is a ip/hostname that function containers will be exposed with, and that is reachable to Dispatch.
	ExternalHost string
	// RetryTimeout specifies the maximum amount of time we should spend retrying calls to docker.
	RetryTimeout time.Duration
	// contains filtered or unexported fields
}

Driver implements a FaaSDriver using Docker daemon. It's a simple driver without scaling or fault tolerance and is not recommended for production usage. It's goal is to provide a simple driver for demos, PoCs, and development use cases.

func New

func New(dockerClient Client) *Driver

New creates a new Docker driver

func (*Driver) Create

func (d *Driver) Create(ctx context.Context, f *functions.Function) error

Create creates new Docker container for a particular function. Currently, there is 1:1 mapping for a function.

func (*Driver) Delete

func (d *Driver) Delete(ctx context.Context, f *functions.Function) error

Delete deletes the function container.

func (*Driver) GetRunnable

func (d *Driver) GetRunnable(e *functions.FunctionExecution) functions.Runnable

GetRunnable creates runnable representation of the function
