如何在 Docker Ubuntu 容器中安裝軟體包？
我使用預設下載的 Ubuntu Docker 映像。我想在它的容器中找到網路介面和IP地址，所以我想安裝包含的包
ifconfig，但是為什麼我失敗了？謝謝。$ sudo docker run ubuntu apt update WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

每個
docker run命令執行一個單獨的容器，因此您的命令的效果不會持續到下一個docker run：在新容器中執行程序。
docker run使用自己的文件系統、自己的網路和自己的隔離程序樹啟動一個程序。您需要組合所有命令：
docker run -it ubuntu /bin/sh -c 'apt update && apt upgrade -y && apt install -y net-tools'添加您要從中執行的任何命令
net-tools。可能值得寫一個
Dockerfile。
