docker || nginx镜像制作

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.Dockerfile

3.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

2023-07-11 16:06:45 (7.52 KB/s) - 已保存 “nginx-1.23.1.tar.gz” [1104352/1104352])

[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 .
[+] Building 136.0s (10/10) FINISHED                                                      docker:default

 => [4/5] WORKDIR /nginx                                                                            0.0s
 => [5/5] RUN set -ex;  bash /nginx/install_nginx.sh;  yum install vim iputils net-tools iproute  129.2s
 => exporting to image                                                                              2.1s
 => => exporting layers                                                                             2.1s
 => => writing image sha256:cdd45d93df0329061058c3ad763e0067c61b65d6641c2cbfcd11c4a1ae67cda7        0.0s 
 => => naming to docker.io/library/sancnginx:1.0                                                    0.0s 

[root@manger nginx]# docker images                                                                       
REPOSITORY   TAG       IMAGE ID       CREATED             SIZE                                           
sancnginx    1.0       cdd45d93df03   27 seconds ago      627MB

第六步：使用制作的镜像启动一个容器

[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
d7cb44d1db8c   sancnginx:1.0   "nginx -g 'daemon of…"   2 seconds ago       Up 1 second        0.0.0.0:4477->80/tcp, :::4477->80/tcp   sanc-nginx-1

第七步：测试访问

http://192.168.2.140:4477/

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 .

 => => transferring context: 15.49kB                                                                0.0s
 => CACHED [2/5] RUN mkdir /nginx                                                                   0.0s

 => [4/5] WORKDIR /nginx                                                                            0.0s
 => [5/5] RUN set -ex;  bash /nginx/install_nginx.sh;  yum install vim iputils net-tools iproute  241.9s
 => exporting to image                                                                              2.3s
 => => exporting layers                                                                             2.3s
 => => writing image sha256:099da6fe30d76ec400ebe70e1d38479ea4ed52757d4f8b89ed99dfe24705ea17        0.0s 
 => => naming to docker.io/library/sancnginx:1.1                                                    0.0s 
[root@manger nginx]# docker images                                                                       
REPOSITORY   TAG       IMAGE ID       CREATED              SIZE                                          
sancnginx    1.1       099da6fe30d7   About a minute ago   627MB

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

[root@manger nginx]# docker ps
CONTAINER ID   IMAGE           COMMAND                   CREATED          STATUS          PORTS                                       NAMES
0796781cfcd6   sancnginx:1.2   "nginx -g 'daemon of…"   6 seconds ago    Up 5 seconds    0.0.0.0:3388->8080/tcp, :::3388->8080/tcp   sanc-nginx-2

第十三步：测试访问

http://192.168.2.140:4477/
