Working with Docker Toolbox

现在我们来看一下如何在 Windows 上使用 Docker Toolbox 处理 Docker 容器。第一步是启动 Docker Toolbox 应用程序,在安装 Docker 工具箱时,会在桌面上创建该应用程序的快捷方式。

Let’s now look at how Docker Toolbox can be used to work with Docker containers on Windows. The first step is to launch the Docker Toolbox application for which the shortcut is created on the desktop when the installation of Docker toolbox is carried out.

接下来,启动 Docker 工具箱时,您将看到正在进行配置。

Next, you will see the configuration being carried out when Docker toolbox is launched.

docker toolbox launched

完成后,您将看到 Docker 已配置并启动。您将获取一个 Docker 交互式外壳。

Once done, you will see Docker configured and launched. You will get an interactive shell for Docker.

为了测试 Docker 是否正常运行,我们可以使用 Docker run command 下载并运行一个简单的 HelloWorld Docker container

To test that Docker runs properly, we can use the Docker run command to download and run a simple HelloWorld Docker container.

Docker run command 的工作原理如下 −

The working of the Docker run command is given below −

docker run

此命令用于在 Docker 容器中运行命令。

This command is used to run a command in a Docker container.

Syntax

docker run image

Options

  1. Image − This is the name of the image which is used to run the container.

Return Value

输出将在所需容器中运行命令。

The output will run the command in the desired container.

Example

sudo docker run hello-world

此命令将下载 hello-world 映像(如果当前不存在),并将 hello-world 作为容器运行。

This command will download the hello-world image, if it is not already present, and run the hello-world as a container.

Output

当我们运行上述命令时,我们将获得以下结果-

When we run the above command, we will get the following result −

docker container

如果您想在 Windows 上运行 Ubuntu OS,可以使用以下命令下载 Ubuntu 映像 −

If you want to run the Ubuntu OS on Windows, you can download the Ubuntu Image using the following command −

Docker run –it ubuntu bash

此处,您通过 –it 选项告诉 Docker 以交互方式运行命令。

Here you are telling Docker to run the command in the interactive mode via the –it option.

ubuntu image

在输出中,您可以看到 Ubuntu 映像已下载并运行,然后您将以 root 用户身份登录 Ubuntu 容器。

In the output you can see that the Ubuntu image is downloaded and run and then you will be logged in as a root user in the Ubuntu container.
