查看Docker容器信息的方法和实现步骤

查看 Docker 容器信息

Docker 是一种轻量级的容器技术，可以提供快速、可移植、可扩展的应用程序部署环境。要查看 Docker 容器信息，可以使用以下步骤：

• 1. 查看所有容器

  可以使用 docker ps -a 命令来查看所有容器，包括正在运行的容器和已停止的容器：

  $ docker ps -a
  CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                      PORTS               NAMES
  d7d5e7c9c2b7        ubuntu              "/bin/bash"              5 minutes ago       Exited (0) 5 minutes ago                       dreamy_mcclintock
      

• 2. 查看容器详细信息

  可以使用 docker inspect <容器 ID> 命令来查看容器的详细信息，例如：

  $ docker inspect d7d5e7c9c2b7
