正如標題所說，我正在嘗試將標簽應用于我的 docker 容器，以便我可以在管道的進一步步驟中參考所述容器。我想要的最終結果是能夠將我的測驗結果從容器中復制出來并發布和顯示這些結果。

在檢查構建步驟后，我可以看到該標簽尚未應用。該powershell步驟特別是docker create --name testcontainer $id變數$id為空的行，并告訴我該標簽從未應用，因此我無法再進一步。
uj5u.com熱心網友回復：
我最終弄清楚了我的問題出在哪里。我最終得到了快取的臨時容器影像。有了這些，Docker 不再運行這些步驟，所以在我在步驟中添加的程序中，但是在構建之前，我沒有從后續呼叫中得到任何東西。
最重要的是，我一直在使用FROM阻止找到我的目錄的指令來參考以前的影像。
