`--org` flag
`NULLSTONE_ORG` env var
`~/.nullstone/<profile>/org` file

Functions

func GetOrg

func GetOrg(c *cli.Context, profile config.Profile) string

func GetProfile

func GetProfile(c *cli.Context) string

func SetupProfileCmd

func SetupProfileCmd(c *cli.Context) (*config.Profile, api.Config, error)

Types

type ErrMultipleAppsFound

type ErrMultipleAppsFound struct {
	AppName    string
	StackNames []string
}

func (ErrMultipleAppsFound) Error

func (e ErrMultipleAppsFound) Error() string

type NsFinder

type NsFinder struct {
	Config api.Config
}

NsFinder is an object that provides a consistent querying approach for nullstone objects through the CLI It provides nice error messages that are tailored for the user flow of CLI commands

func (NsFinder) GetApp

func (f NsFinder) GetApp(appName string, stackName string) (*types.Application, error)

GetApp searches for an app by app name and optionally stack name If only 1 app is found, returns that app If many are found, will return an error with matched app stack names

func (NsFinder) GetAppAndWorkspace

func (f NsFinder) GetAppAndWorkspace(appName, stackName, envName string) (*types.Application, *types.Workspace, error)

This retrieves the app and workspace stackName is optional -- If multiple apps are found, this will return an error

func (NsFinder) GetWorkspace

func (f NsFinder) GetWorkspace(stackName, blockName, envName string) (*types.Workspace, error)
