無法替換docker中的軟件源碼Ubuntu鏡像

Question

我在docker上安裝了Ubuntu 14.04鏡像。該鏡像帶有Ubuntu官方軟件源碼。由於我在中國，無法連接到這些服務器，因此我必須編輯etc/apt/source.list用vi或vim替換軟件源。但是，Ubuntu映像不會與兩個編輯器中的任何一個一起提供。如果我嘗試 來安裝編輯器，那麼我必須更改軟件源。我怎麼解決這個問題？

Answer 1

如下您可以創建一個派生泊塢窗圖像：

Dockerfile

FROM ubuntu:14.04 
COPY ./sources.list /etc/apt/ 

sources.list（我在中國使用這些之前，他們的工作很好，跟你喜歡的人替換）

創建這些文件後，您可以通過運行來構建映像，例如：

docker build --tag ubuntu:14.04-cn 

並在您的項目中使用它，如果您需要將其上傳到碼頭集線器，則需要相應地更改名稱。

此外，我建議您直接在圖像中安裝所需的軟件，這樣您不必在每次啓動容器時都安裝依賴項，因爲無論如何您都在構建圖像。
