Implementations§

Source§

impl BlueGreenManager

Source

pub fn new(config: BlueGreenConfig) -> Result<Self, ApplicatorError>

新しい Manager を作成

Source

pub fn config(&self) -> &BlueGreenConfig

設定を取得

Source

pub fn state(&self) -> ServerState

現在のサーバー状態を取得

Source

pub fn active_endpoint(&self) -> String

現在リクエストを送るべきエンドポイントを取得

状態に応じて適切なサーバーを返す:

  • Active: アクティブサーバー
  • Starting: 旧サーバー(まだ稼働中)
  • Releasing: 新サーバー(既に稼働中)
  • Down: アクティブサーバー(実際は利用不可)
Source

pub fn standby_endpoint(&self) -> String

Standby(次に起動する側)のエンドポイントを取得

Source

pub async fn start(&self, loras: &[PathBuf]) -> Result<(), ApplicatorError>

初期起動(Blue を起動)

Source

pub async fn switch_with_new_lora( &self, new_lora: &Path, ) -> Result<(), ApplicatorError>

新しい LoRA を追加して切り替え

Source

pub async fn switch_with_loras( &self, loras: &[PathBuf], ) -> Result<(), ApplicatorError>

指定した LoRA セットで切り替え

§状態遷移
Active → Starting → Active → Releasing → Active
         (新起動)   (切替)   (旧停止)

Starting/Releasing 中もリクエストは処理可能(ダウンタイムなし)

Source

pub async fn switch_with_model( &self, model: &TrainedModel, ) -> Result<(), ApplicatorError>

TrainedModel を使って切り替え

Source

pub async fn stop_all(&self) -> Result<(), ApplicatorError>

両サーバーを停止

Source

pub fn loaded_loras(&self) -> Vec<PathBuf>

現在ロード済みの LoRA 一覧を取得

Source

pub fn is_blue_active(&self) -> bool

Blue がアクティブかどうか

Source

pub fn switching_behavior(&self) -> &SwitchingBehavior

切り替え中の挙動設定を取得

Source

pub async fn wait_until_available(&self) -> Result<(), ApplicatorError>

サーバーが利用可能になるまで待機(Waiting モード用)

Starting/Releasing 状態でもリクエスト可能なので、この関数は 主に Down 状態からの回復待機に使用。

SwitchingBehavior::WaitForReady の場合、利用可能になるまで待機。 SwitchingBehavior::FailImmediately の場合は即座に結果を返す。
