【打工日常】使用docker部署linux-command解析搜索工具

一、linux-command介绍

linux-command工具是一个非盈利性的工具，里面记录了550 个 Linux 命令，内容包含 Linux 命令手册、详解、学习，是值得收藏的 Linux 命令速查手册。内容来自网络和网友的补充。

二、本次实践介绍

1. 本次实践简介

本次实践部署环境为个人测试环境

2. 本地环境规划

本次实践环境规划：docker快速拉取linux-command镜像，然后后台启动linux-command镜像

启动镜像后的名字	IP地址	容器镜像版本	操作系统版本
linux-command	192.168.20.8	latest	ubuntu 22.04

三、检查本地Docker环境

检查Docker版本：docker version
root@WellDone:/home/goodjob# docker version

  GitCommit:        v1.1.11-0-g4bccb38
 docker-init:
  Version:          0.19.0
  GitCommit:        de40ad0
root@WellDone:/home/goodjob#

2. 检查Docker服务状态

检查Docker服务状态，确保Docker服务正常运行

systemctl status docker

root@WellDone:/home/goodjob/Downloads# systemctl status docker

四、部署linux-command镜像

1. 下载linux-command镜像
docker pull wcjiang/linux-command

root@WellDone:/home/goodjob# docker pull wcjiang/linux-command
Using default tag: latest
latest: Pulling from wcjiang/linux-command
66075c0cb3a1: Pull complete 
d3b8bfc32667: Pull complete

Status: Downloaded newer image for wcjiang/linux-command:latest
docker.io/wcjiang/linux-command:latest

root@WellDone:/home/goodjob# docker images
REPOSITORY                                           TAG        IMAGE ID       CREATED         SIZE

wcjiang/linux-command                                latest     bc7bd37fedce   2 weeks ago     59.3MB

2. 创建容器
使用docker快速创建linux-command的容器。
完整创建过程：

a.启动一个linux-command的测试容器。

docker run -d  --name linux-command --restart always  -p 6868:3000 wcjiang/linux-command:latest

b.启动完毕后查看下是否启动正常

root@WellDone:/home/goodjob# docker ps
CONTAINER ID   IMAGE                                                       COMMAND                   CREATED         STATUS        PORTS                                       NAMES
4a36b9f7a146   wcjiang/linux-command:latest                                "/busybox httpd -f -…"   2 seconds ago   Up 1 second   0.0.0.0:6868->3000/tcp, :::6868->3000/tcp   linux-command                               "./server"                3 seconds ago   Up 2 seconds   0.0.0.0:1234->8999/tcp, :::1234->8999/tcp   docker-ui

c.容器启动正常，访问
http://ip:6868

3. 检查容器运行状态
检查容器的运行状态，确保服务的正常运行。
docker ps
root@WellDone:/home/goodjob# docker ps
CONTAINER ID   IMAGE                                                       COMMAND                   CREATED         STATUS        PORTS                                       NAMES
4a36b9f7a146   wcjiang/linux-command:latest
