type Client interface {
	client.APIClient
	ExtractNetworksForContainer(containerName string) (map[string]*network.EndpointSettings, error)
	ConnectContainerToNetworks(containerName string, settings map[string]*network.EndpointSettings) error
	AttachNetwork(containerName string, networkName []string) error
	StopAndRemoveDockerContainer() error
	GetContainerID() string
	SetContainerID(containerID string)
	NetworkExists(network string) (bool, error)

	HasRelativePath(c *Compose) bool
	ForceAbsolutePath(c *Compose, basePath string) error

	GetNetworkInfo(compose *Compose) *NetworkInfo

	CreateNetwork(network string) error
	MakeNetworkExternal(c *Compose) error
	SetKeployNetwork(c *Compose) (*NetworkInfo, error)
	ReadComposeFile(filePath string) (*Compose, error)
	WriteComposeFile(compose *Compose, path string) error
}

func New

func New(logger *zap.Logger) (Client, error)

type Compose

type Compose struct {
	Version  string    `yaml:"version,omitempty"`
	Services yaml.Node `yaml:"services,omitempty"`
	Networks yaml.Node `yaml:"networks,omitempty"`
	Volumes  yaml.Node `yaml:"volumes,omitempty"`
	Configs  yaml.Node `yaml:"configs,omitempty"`
	Secrets  yaml.Node `yaml:"secrets,omitempty"`
}

Compose structure to represent all the fields of a Docker Compose file

type Impl

type Impl struct {
	nativeDockerClient.APIClient
	// contains filtered or unexported fields
}

func (*Impl) AttachNetwork

func (idc *Impl) AttachNetwork(containerName string, networkNames []string) error

func (*Impl) ConnectContainerToNetworks

func (idc *Impl) ConnectContainerToNetworks(containerName string, settings map[string]*network.EndpointSettings) error

func (*Impl) CreateNetwork

func (idc *Impl) CreateNetwork(networkName string) error

CreateNetwork creates a custom docker network of type bridge.

func (*Impl) ExtractNetworksForContainer

func (idc *Impl) ExtractNetworksForContainer(containerName string) (map[string]*network.EndpointSettings, error)

ExtractNetworksForContainer returns the list of all the networks that the container is a part of. Note that if a user did not explicitly attach the container to a network, the Docker daemon attaches it to a network called "bridge".

func (*Impl) ForceAbsolutePath

func (idc *Impl) ForceAbsolutePath(c *Compose, basePath string) error

ForceAbsolutePath replaces relative paths in bind mounts with absolute paths

func (*Impl) GetContainerID

func (idc *Impl) GetContainerID() string

GetContainerID is a Getter function for containerID

func (*Impl) GetHostWorkingDirectory

func (idc *Impl) GetHostWorkingDirectory() (string, error)

GetHostWorkingDirectory Inspects Keploy docker container to get bind mount for current directory

func (*Impl) GetNetworkInfo

func (idc *Impl) GetNetworkInfo(compose *Compose) *NetworkInfo

GetNetworkInfo CheckNetworkInfo returns information about network name and also about whether the network is external or not in a docker-compose file.

func (*Impl) HasRelativePath

func (idc *Impl) HasRelativePath(compose *Compose) bool

HasRelativePath returns information about whether bind mounts if they are being used contain relative file names or not

func (*Impl) MakeNetworkExternal

func (idc *Impl) MakeNetworkExternal(c *Compose) error

MakeNetworkExternal makes the existing network of the user docker compose file external and save it to a new file

func (*Impl) NetworkExists

func (idc *Impl) NetworkExists(networkName string) (bool, error)

NetworkExists checks if the given network exists locally or not

func (*Impl) ReadComposeFile

func (idc *Impl) ReadComposeFile(filePath string) (*Compose, error)

func (*Impl) SetContainerID

func (idc *Impl) SetContainerID(containerID string)

SetContainerID is a Setter function for containerID

func (*Impl) SetKeployNetwork

func (idc *Impl) SetKeployNetwork(c *Compose) (*NetworkInfo, error)

SetKeployNetwork adds the keploy-network network to the new docker compose file and copy rest of the contents from existing user docker compose file

func (*Impl) StopAndRemoveDockerContainer

func (idc *Impl) StopAndRemoveDockerContainer() error

StopAndRemoveDockerContainer will Stop and Remove the docker container

func (*Impl) WriteComposeFile

func (idc *Impl) WriteComposeFile(compose *Compose, path string) error

type NetworkInfo

type NetworkInfo struct {
	External bool
	Name     string
}
