Types

type Container

type Container interface {
	GetContainerID() string                                         // get the container id from the provider
	Endpoint(context.Context, string) (string, error)               // get proto://ip:port string for the first exposed port
	PortEndpoint(context.Context, nat.Port, string) (string, error) // get proto://ip:port string for the given exposed port
	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
	Name(context.Context) (string, error)                           // get container name
}

Container allows getting info about and controlling a single container instance

func GenericContainer

func GenericContainer(ctx context.Context, req GenericContainerRequest) (Container, error)

GenericContainer creates a generic container with parameters

type ContainerProvider

type ContainerProvider interface {
	CreateContainer(context.Context, ContainerRequest) (Container, error) // create a container without starting it
	RunContainer(context.Context, ContainerRequest) (Container, error)    // create a container and start it
}

ContainerProvider allows the creation of containers on an arbitrary system

type ContainerRequest

type ContainerRequest struct {
	Image        string
	Env          map[string]string
	ExposedPorts []string // allow specifying protocol info
	Cmd          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

type DeprecatedContainer interface {
	GetHostEndpoint(ctx context.Context, port string) (string, string, error)
	GetIPAddress(ctx context.Context) (string, error)
	LivenessCheckPorts(ctx context.Context) (nat.PortSet, error)
	Terminate(ctx context.Context) error
}

DeprecatedContainer shows methods that were supported before, but are now deprecated Deprecated: Use Container

type DockerContainer

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

DockerContainer represents a container started using Docker

func (*DockerContainer) Endpoint

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

Endpoint gets proto://host:port string for the first exposed port Will returns just host:port if proto is ""

func (*DockerContainer) GetContainerID

func (c *DockerContainer) GetContainerID() string

func (*DockerContainer) Host

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

Host gets host (ip or name) of the docker daemon where the container port is exposed Warning: this is based on your Docker host setting. Will fail if using an SSH tunnel You can use the "TC_HOST" env variable to set this yourself

func (*DockerContainer) Logs

Logs will fetch both STDOUT and STDERR from the current container. Returns a ReadCloser and leaves it up to the caller to extract what it wants.

func (*DockerContainer) MappedPort

func (c *DockerContainer) MappedPort(ctx context.Context, port nat.Port) (nat.Port, error)

MappedPort gets externally mapped port for a container port

func (*DockerContainer) Name

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

Name gets the name of the container.

func (*DockerContainer) PortEndpoint

func (c *DockerContainer) PortEndpoint(ctx context.Context, port nat.Port, proto string) (string, error)

PortEndpoint gets proto://host:port string for the given exposed port Will returns just host:port if proto is ""

func (*DockerContainer) Ports

func (c *DockerContainer) Ports(ctx context.Context) (nat.PortMap, error)

Ports gets the exposed ports for the container.

func (*DockerContainer) SessionID

func (c *DockerContainer) SessionID() string

SessionID gets the current session id

func (*DockerContainer) Start

func (c *DockerContainer) Start(ctx context.Context) error

Start will start an already created container

func (*DockerContainer) Terminate

func (c *DockerContainer) Terminate(ctx context.Context) error

Terminate is used to kill the container. It is usally triggered by as defer function.

type DockerProvider

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

DockerProvider implements the ContainerProvider interface

func NewDockerProvider

func NewDockerProvider() (*DockerProvider, error)

NewDockerProvider creates a Docker provider with the EnvClient

func (*DockerProvider) CreateContainer

func (p *DockerProvider) CreateContainer(ctx context.Context, req ContainerRequest) (Container, error)

CreateContainer fulfills a request for a container without starting it

func (*DockerProvider) RunContainer

func (p *DockerProvider) RunContainer(ctx context.Context, req ContainerRequest) (Container, error)

RunContainer takes a RequestContainer as input and it runs a container via the docker sdk

type GenericContainerRequest

type GenericContainerRequest struct {
	ContainerRequest              // embedded request for provider
	Started          bool         // whether to auto-start the container
	ProviderType     ProviderType // which provider to use, Docker if empty
}

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

func (t ProviderType) GetProvider() (ContainerProvider, error)

GetProvider provides the provider implementation for a certain type

type Reaper

type Reaper struct {
	Provider  ReaperProvider
	SessionID string
	Endpoint  string
}

Reaper is used to start a sidecar container that cleans up resources

func NewReaper

func NewReaper(ctx context.Context, sessionID string, provider ReaperProvider) (*Reaper, error)

NewReaper creates a Reaper with a sessionID to identify containers and a provider to use

func (*Reaper) Connect

func (r *Reaper) Connect() (chan bool, error)

Connect runs a goroutine which can be terminated by sending true into the returned channel

func (*Reaper) Labels

func (r *Reaper) Labels() map[string]string

Labels returns the container labels to use so that this Reaper cleans them up

type ReaperProvider

type ReaperProvider interface {
	RunContainer(ctx context.Context, req ContainerRequest) (Container, error)
}

ReaperProvider represents a provider for the reaper to run itself with The ContainerProvider interface should usually satisfy this as well, so it is pluggable
