Functions

func ConfigPath

func ConfigPath() string

ConfigPath returns the path to the user config file

Types

type Client

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

Client provides authenticated API access for creating, listing, and destroying database servers.

func NewClient

func NewClient(cfg *Config) (*Client, error)

NewClient creates a mktmpio Client using credentials loaded from the user config stored in ~/.mktmpio.yml

func (Client) Attach

func (c Client) Attach(id string) (io.ReadWriteCloser, error)

Attach creates a remote shell for the instance identified by `id` and then returns a Reader and a Writer for communicating with it via a pseudo-TTY. The bytes read from the channel will include TTY control sequences. This type of connection is most appropriate for connecting directly to a local TTY.

func (Client) AttachStdio

func (c Client) AttachStdio(id string) (io.WriteCloser, io.Reader, io.Reader, error)

AttachStdio creates a remote shell for the instance identified by `id` and returns an io.WriteCloser for that shell's stdin and an io.Reader for each of stdout and stderr on that shell. This is for non-interactive shells, like one would use for piping a script into a shell or for piping the output from.

func (Client) Create

func (c Client) Create(service string) (*Instance, error)

Create creates a server of the type specified by `service`.

func (Client) Destroy

func (c Client) Destroy(id string) error

Destroy shuts down and deletes the server identified by `id`.

func (Client) List

func (c Client) List() ([]Instance, error)

List generates retrieves a list of curently running instances

func (*Client) SetLogger

func (c *Client) SetLogger(logger *log.Logger)

SetLogger sets the logger to be used for verbose logging of errors

type Config

type Config struct {
	Token string
	URL   string `yaml:",omitempty"`
	// contains filtered or unexported fields
}

Config contains the user config options used for accessing the mktmpio API.

func DefaultConfig

func DefaultConfig() *Config

DefaultConfig returns a configuration with only the default values set

func EnvConfig

func EnvConfig() *Config

EnvConfig returns a configuration with only values provided by environment variables

func FileConfig

func FileConfig(cfgPath string) *Config

FileConfig returns a configuration with any values provided by the given YAML config file

func LoadConfig

func LoadConfig() *Config

LoadConfig loads the configuration stored in `~/.mktmpio.yml`, returning it as a Config type instance.

func (*Config) Apply

func (c *Config) Apply(b *Config) *Config

Apply creates a new Config with non-empty values from the provided Config overriding the options of the base Config

func (*Config) Save

func (c *Config) Save(cfgPath string) error

Save stores the given configuration in ~/.mktmpio.yml, overwriting the current contents if the file exists.

func (Config) String

func (c Config) String() string

type Instance

type Instance struct {
	ID             string
	Host           string
	Port           int
	Error          string
	RemoteShell    shell
	Type           string
	Username       string
	Password       string
	ContainerShell []string
	// contains filtered or unexported fields
}

Instance represents a server that has been created on the mktmpio service.

func (*Instance) Cmd

func (i *Instance) Cmd() *exec.Cmd

Cmd returns an exec.Cmd that is pre-populated with the command, arguments, and environment variables required for spawning a local shell connected to the remote server.

func (*Instance) Destroy

func (i *Instance) Destroy() error

Destroy the server on the mktmpio service

func (*Instance) LoadEnv

func (i *Instance) LoadEnv() error

LoadEnv modifies the current environment by setting environment variables that contain the host, port and credentials required for connecting to the remote server represented by the Instance.
