Functions

func AcquireApplicationLock 

func AcquireApplicationLock(appName string, owner string, reason string) (bool, error)

AcquireApplicationLock acquires an application lock by setting the lock field in the database. This method is already called by a connection middleware on requests with :app or :appname params that have side-effects.

func AcquireApplicationLockWait 

func AcquireApplicationLockWait(appName string, owner string, reason string, timeout time.Duration) (bool, error)

Same as AcquireApplicationLock but it keeps trying to acquire the lock until timeout is reached.

func ChangeQuota 

func ChangeQuota(app *App, limit int) error

ChangeQuota redefines the limit of the app. The new limit must be bigger than or equal to the current number of units in the app. The new limit may be smaller than 0, which means that the app should have an unlimited number of units.

func CreateApp 

func CreateApp(app *App, user *auth.User) error

CreateApp creates a new app.

Creating a new app is a process composed of the following steps:

  1. Save the app in the database
  2. Create the git repository using the repository manager
  3. Provision the app using the provisioner

func Delete 

func Delete(app *App, w io.Writer) error

Delete deletes an app.

func Deploy 

func Deploy(opts DeployOptions) error

Deploy runs a deployment of an application. It will first try to run an archive based deploy (if opts.ArchiveURL is not empty), and then fallback to the Git based deployment.

func ReleaseApplicationLock 

func ReleaseApplicationLock(appName string)

func SaveDiffData 

func SaveDiffData(diff string, appName string) error

func Swap 

func Swap(app1, app2 *App) error
