一，查看容器（假设你有一个名为 `my_app_container` 的容器）。

  1. 查看所有容器（包括已停止的）

docker ps -a

输出示例：

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

123456789abc my_app_image "npm start" 2 hours ago Up 2 hours 3000/tcp my_app_container

def4567890ab another_image "python app.py" 3 days ago Exited (0) 3 days ago another_container

  1. 获取容器的详细信息

docker inspect my_app_container

输出示例（部分）：

  1. 获取容器的IP地址

docker inspect -f '{{ .NetworkSettings.IPAddress }}' my_app_container

输出示例：

172.17.0.2

  1. 查看容器的日志输出

docker logs --tail 100 -f my_app_container

输出示例：

> my_app@1.0.0 start

> node app.js
