1.以centos7作为基础镜像
2.安装好ip，vim，ping命令
3.编译安装nginx（编写脚本）
4.使用指定的配置文件nginx.conf
5.启动容器的时候启动nginx
6.网站的网页上传到容器里：
1.直接做到镜像里
2.使用数据卷挂载使用
/usr/local/nginx1/conf
需要哪些东西？
1.nginx的安装脚本 install_nginx.sh -->源码
https://nginx.org/download/nginx-1.23.1.tar.gz
2.Dockerfile3.编译安装nginx的配置文件
第一步：新建文件夹nginx
[root@manger mynginx]# mkdir nginx
[root@manger mynginx]# cd nginx/
第二步：下载nginx源码包
[root@manger nginx]# wget https://nginx.org/download/nginx-1.23.1.tar.gz

[root@manger nginx]# ls
nginx-1.23.1.tar.gz第三步：编写一键安装nginx的脚本
[root@manger nginx]# cat install_nginx.sh
#!/bin/bash
#解决依赖关系
yum install -y zlib zlib-devel openssl openssl-devel pcre pcre-devel gcc gcc-c++ autoconf automake make
#新建/nginx目录
mkdir -p /nginx
#进入/nginx
cd /nginx
#解压下载的nginx源码包
tar xf nginx-1.23.1.tar.gz
cd nginx-1.23.1
#编译前配置
./configure --prefix=/usr/local/nginx1 --with-threads --with-http_ssl_module --with-http_stub_status_module --with-stream
#编译
make
#编译安装
make install第四步：编写Dockerfile
[root@manger nginx]# cat Dockerfile
FROM centos:7
ENV NGINX_VERSION 1.23.1
ENV AUTHOR jack
ENV PATH=/usr/local/nginx1/sbin:$PATH
LABEL maintainer="jack<[email protected]>"
RUN mkdir /nginx
COPY . /nginx
WORKDIR /nginx
RUN set -ex; \
bash install_nginx.sh; \
yum install vim iputils net-tools iproute -y
EXPOSE 80
STOPSIGNAL SIGQUIT
CMD ["nginx","-g","daemon off;"]
[root@manger nginx]# ls
Dockerfile install_nginx.sh nginx-1.23.1.tar.gz第五步：制作镜像
[root@manger nginx]# docker build -t sancnginx:1.0 .

[root@manger nginx]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE

[root@manger nginx]# docker run -d -p 4477:80 --name sanc-nginx-1 sancnginx:1.0
d7cb44d1db8c8245fdfc14d9d060ca274527b28ebe5bc63d2231e5a05f199eae
[root@manger nginx]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

第八步：把编译安装nginx的配置文件从容器里拷贝出来
[root@manger nginx]# docker cp sanc-nginx-1:/usr/local/nginx1/conf/nginx.conf .
Successfully copied 4.61kB to /mynginx/nignx/.
[root@manger nginx]# ls
Dockerfile install_nginx.sh nginx-1.23.1.tar.gz nginx.conf
第九步：修改nginx.conf配置文件;修改Dockerfile
[root@manger nginx]# vim nginx.conf
worker_processes 2;
events {
worker_connections 4096;
}
server {
listen 8080;
server_name localhost;
[root@manger nginx]# cat Dockerfile
FROM centos:7
ENV NGINX_VERSION 1.23.1
ENV AUTHOR jack
ENV PATH=/usr/local/nginx1/sbin:$PATH
LABEL maintainer="jack<[email protected]>"
RUN mkdir /nginx
COPY . /nginx
WORKDIR /nginx
RUN set -ex; \
bash install_nginx.sh; \
yum install vim iputils net-tools iproute -y
EXPOSE 8080
COPY ./nginx.conf /usr/local/nginx1/conf
STOPSIGNAL SIGQUIT
CMD ["nginx","-g","daemon off;"]
第十步：重新制作镜像
[root@manger nginx]# docker build -t sancnginx:1.1 .

[root@manger nginx]# docker images

第十一步：创建卷
[root@manger nginx]# docker volume create sc
sc
[root@manger nginx]# docker volume ls
DRIVER VOLUME NAME
local sc
local test-vol
[root@manger nginx]# docker volume inspect sc
[
{
"CreatedAt": "2023-07-11T17:32:36+08:00",
"Driver": "local",
"Labels": null,
"Mountpoint": "/var/lib/docker/volumes/sc/_data",
"Name": "sc",
"Options": null,
"Scope": "local"
}
]
[root@manger nginx]# cd /var/lib/docker/volumes/sc/_data/
[root@manger _data]# echo "hello world,welcome to changshasanchuang" >>index.html
[root@manger _data]# ls
index.html
[root@manger _data]# cat index.html
hello world,welcome to changshasanchuang
第十二步：使用新制作的镜像启动容器并且使用卷挂载
[root@manger nginx]# docker run -d --name sanc-nginx-2 -p 3388:8080 --mount source=sc,target=/usr/local/nginx1/html sancnginx:1.1
0796781cfcd6bc20e548b3c79cf1d61bec1f4b83f678738c4a7480fd19c3b146
