一、搭建NGINX

1.1创建新的dockerfile

cd /mydockerfile/
mkdir myrydf
cd myrydf/

1.2优化NGINX安装

# 进入容器安装NGINX数据
docker run -it rockylinux:9 
[root@8fd80d4ab610 /]# dnf install nginx# 安装完选择n不继续安装打成镜像，方便后面实验
docker commit -a "laowang" -m "rknew9" 8fd80d4ab610 rknew9
#输出如下： 
sha256:bae1105f6e4a7f8339e2c158b3eb6b343edebd77b279e5a8bcb60209da77894b

1.3准备相应文件

# 导入dist文件到myrydf
dist.tar.gz# 主机安装NGINX拷贝配置文件到myrydf
dnf install -y nginx
cp /etc/nginx/nginx.conf /mydockerfile/myrydf/# 修改nginx.conf文件为如下9 daemon off;39         listen       88;42         root         /dist;45         include /etc/nginx/default.d/*.conf;46         location / {47            root /dist;48            index index.html index.htm;49         }

1.4写入dockerfile

# 写入dockerfile
cat >/mydockerfile/myrydf/Dockerfile<<LW
# 指定基础镜像为rknew9
FROM rknew9
# 运行安装NGINX
RUN dnf install nginx -y
# 解压文件到/下
ADD dist.tar.gz /
# 拷贝文件到目标目录
COPY nginx.conf /etc/nginx/nginx.conf
# 指定端口为88
EXPOSE 88
# 启动NGINX
CMD ["/usr/sbin/nginx","-c","/etc/nginx/nginx.conf"]
LW

1.5构建镜像

docker build -t ryui .
#输出如下： 
[+] Building 0.0s (9/9) FINISHED                                       docker:default=> [internal] load build definition from Dockerfile                             0.0s=> => transferring dockerfile: 331B                                             0.0s=> [internal] load metadata for docker.io/library/rknew9:latest                 0.0s=> [internal] load .dockerignore                                                0.0s=> => transferring context: 2B                                                  0.0s=> [1/4] FROM docker.io/library/rknew9:latest                                   0.0s=> [internal] load build context                                                0.0s=> => transferring context: 2.39kB                                              0.0s=> CACHED [2/4] RUN dnf install nginx -y                                        0.0s=> CACHED [3/4] ADD dist.tar.gz /                                               0.0s=> [4/4] COPY nginx.conf /etc/nginx/nginx.conf                                  0.0s=> exporting to image                                                           0.0s=> => exporting layers                                                          0.0s=> => writing image sha256:6f36c8187afb90810361db8dd5f88f369eb1e78140a7f8d8bab  0.0s=> => naming to docker.io/library/ryui                                          0.0s

1.6启动容器

docker run -d -P ryui:latest # 查看端口号
docker ps -l
CONTAINER ID   IMAGE         COMMAND                  CREATED         STATUS         PORTS                                       NAMES
