// Implements support for running the storage node as a Windows Service.
|
|
//
|
|
// The Windows Service can be created with sc.exe, e.g.
|
|
//
|
|
// sc.exe create storagenode binpath= "C:\Users\MyUser\storagenode.exe run --config-dir C:\Users\MyUser\"
|
|
//
|
|
// The --config-dir argument can be omitted if the config.yaml is available at
|
|
// C:\Windows\System32\config\systemprofile\AppData\Roaming\Storj\Storagenode\config.yaml
