Docker busybox usage and common operating system images

Busybox is a software toolbox that integrates hundreds of commonly used linux commands and tools in linux. In many cases, we may need to install some virtual systems, including some environment configurations, so we need to download some operating system images, such as ubuntu and centos.
1. busybox image.
First query the image:
Docker search busybox

[Root @ niaoyun43442 yum. repos. d] # docker search busybox

Download Image: docker pull docker. io/busybox

[Root @ niaoyun43442 yum. repos. d] # docker pull docker. io/busybox

You can directly use docker run-ti busybox to create a container and perform the following operations.
Create the container busyboxtest based on the busybox image:

[Root @ niaoyun43442 yum. repos. d] # docker run-RTL -- name busyboxtest docker. io/busybox/bin/sh
Bytes
[Root @ niaoyun43442 yum. repos. d] # docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
79e34ddeaf6d docker. io/busybox "/bin/sh" 4 seconds ago Up 3 seconds busyboxtest
Go to the container and enter bin to view common commands:

[Root @ niaoyun43442 yum. repos. d] # docker exec-ti busyboxtest/bin/bash
/# Cd bin/
/Bin # ls

2. Operating system
You can use docker search osname to view images. For example:
Docker search centos
Docker search ubuntu
And so on. After creating a container based on the image, the container can be used normally. You can also encapsulate the container to form a new image template.

Note:
(1) official images are generally relatively small and only common components are installed. They are universal and have better plasticity. We recommend that you download this image for Configuration Optimization.
(2) some images uploaded by individuals or organizations have a wide range of content and are suitable for test handeners, but may not be suitable for their production environments.
