# portainer簡易操作(二)

## 更新運作中的容器很簡單，如果你希望更新容器到最新的映像檔時候，只要按下上排快捷鍵的「Recreate」按鈕

![](/files/-Lkh5QNf7vcc193ZBkxb)

它就會問你是不是確定要下載最新映像檔重新建立更新

<div align="left"><img src="/files/-Lkh5oCZ04L9ma0Ja32k" alt=""></div>

來到 Portainer 的「images」頁面，可以發現很多黃色「Unused」沒在使用的舊映像檔，當你確認新的容器運作無誤後，直接把舊的映像檔勾選起來，然後按下「Remove」即可
