Docker
如何在 ubuntu docker 鏡像上安裝 tzdata？
我在 Dockerfile 中有以下行。
RUN apt-get install -y tzdata當我執行它時，它會詢問我的輸入。在我提供我的輸入後，它就掛在那裡了。有誰知道如何解決這個問題？

僅一行：
RUN DEBIAN_FRONTEND=noninteractive TZ=Etc/UTC apt-get -y install tzdata
您可以使用
ARG和ENV指令對您有利：ARG DEBIAN_FRONTEND=noninteractive ENV TZ=Europe/Moscow RUN apt-get install -y tzdata這種方式
DEBIAN_FRONTEND只會在您建構圖像時定義，而TZ將在執行時持續存在。
