Overview

Client package provides a client that allows to interact with the a CARAVELA's daemon sending the requests to it. It can be used as a Golang SDK for the CARAVELA's. This is the same client used in the CLI github.com/strabox/caravela/cli provided.

Types

type Client

type Client struct {
	// contains filtered or unexported fields
}

Client holds all the necessary information to interact with CARAVELA's daemon.

func NewCaravelaIP

func NewCaravelaIP(caravelaHostIP string) *Client

NewCaravelaIP creates a new client for a CARAVELA's daemon hosted in the given IP.

func NewCaravelaTimeoutIP

func NewCaravelaTimeoutIP(caravelaHostIP string, requestTimeout time.Duration) *Client

func (*Client) ListContainers

func (client *Client) ListContainers(ctx context.Context) ([]types.ContainerStatus, *Error)

ListContainers returns a slice of container status that represent all the containers that the user have running in the CARAVELA's system.

func (*Client) Shutdown

func (client *Client) Shutdown(ctx context.Context) *Error

Shutdown makes the daemon cleanly shutdown and leave the system.

func (*Client) StopContainers

func (client *Client) StopContainers(ctx context.Context, containersIDs []string) *Error

StopContainers stops and removes all the containers given by the containersIDs slice.

func (*Client) SubmitContainers

func (client *Client) SubmitContainers(c context.Context, containersConfigs []types.ContainerConfig) *Error

SubmitContainers allows to submit a set of containers that you want to deploy in the CARAVELA's system. The containers configurations are given by the containersConfigs slice.

type Configuration

type Configuration struct {
	// contains filtered or unexported fields
}

Configuration holds the configuration parameters for the CARAVELA's client.

func DefaultConfig

func DefaultConfig(caravelaInstanceIP string) *Configuration

DefaultConfig creates a new configuration structure with the default values.

func (*Configuration) CaravelaInstanceIP

func (config *Configuration) CaravelaInstanceIP() string

CaravelaInstanceIP returns the IP address to where send the API requests.

func (*Configuration) CaravelaInstancePort

func (config *Configuration) CaravelaInstancePort() int

CaravelaInstancePort returns the port to where send the API requests.

func (*Configuration) RequestTimeout

func (config *Configuration) RequestTimeout() time.Duration

RequestTimeout returns the timeout for the API requests.

func (*Configuration) SetCaravelaInstancePort

func (config *Configuration) SetCaravelaInstancePort(newPort int)

SetCaravelaInstancePort sets the port to where send the API requests.

func (*Configuration) SetRequestTimeout

func (config *Configuration) SetRequestTimeout(newReqTimeout time.Duration)

SetRequestTimeout sets the timeout for the API requests.

type Error

type Error struct {

	// Error's code.
	Code int
	// contains filtered or unexported fields
}

Error represents the errors returned by the CARAVELA's client. It implements the error interface.

func (*Error) Error

func (ce *Error) Error() string
