Docker busybox 镜像工具

busybox 本身集成了300多个常用工具命令. 用于日常开发,维护.也是体积比较小. 但是 busybox 本身不支持 curl,很遗憾,所以有了衍生品.

.1. busybox

原生的 busybox, 大小718K左右,不及1M大小.

本身采用 apt-get install 安装工具

.2. progrium/busybox

官方地址: https://hub.docker.com/r/progrium/busybox

支持创建自己的镜像,安装,采用 opkg-install 安装软件.

FROM progrium/busybox
RUN opkg-install curl bash git
CMD ["/bin/bash"]

.3. Alpine

.3.1. Alpine 替换国内源

# 查看镜像源
cat /etc/apk/repositories

http://dl-cdn.alpinelinux.org/alpine/v3.11/community

# 替换阿里云
sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories

# 替换科技大学
sed -i 's/dl-cdn.alpinelinux.org/mirrors.ustc.edu.cn/g' /etc/apk/repositories

# 替换清华源
sed -i 's/dl-cdn.alpinelinux.org/mirrors.tuna.tsinghua.edu.cn/g' /etc/apk/repositories

.3.2. Dockerfile

RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.tuna.tsinghua.edu.cn/g' /etc/apk/repositories
RUN apk add --no-cache gcc musl-dev linux-headers

.3.3. 升级&安装软件

# 升级
apk update
apk upgrade

# 安装 bash
apk add --no-cache bash

# 安装 bash 文档
apk add bash-doc

# 安装 bash 自动化命令行
apk add bash-completion zsh vim curl

# 改变当前环境 Bash

.4. sgfoot/busybox

基于 alpine:3.15.4 构建 busybox 工具箱。

.4.1. 支持常用命令

  1. curl 是一款很强大的http命令行工具
  2. wget 是一个下载文件的工具
  3. bash 支持数组
  4. nc 在网络工具中有“瑞士军刀”美誉
  5. nc ip port
  6. nc -l 9999 > a.tgz 开启监听
  7. nc ip port < a.tgz 发送数据
  8. ping 用来作为网络可用性的检查
  9. nslookup 查询域名信息的一个非常有用的命令
  10. traceroute 用于追踪数据包在网络上的传输时的全部路径
