基于dockerfile制作apache镜像

• 准备工作

[root@cxr ~]# mkdir -p /opt/apache/files
[root@cxr ~]# cd /opt/apache/
[root@cxr apache]# touch Dockerfile
[root@cxr apache]# ls
dockerfile  files
[root@cxr apache]# tree
.
├── Dockerfile
└── files
    ├── apr-1.7.0.tar.gz
    ├── apr-util-1.6.1.tar.gz
    └── httpd-2.4.53.tar.gz

• 编写dockerfile文件

[root@cxr dockerfile]# vim Dockerfile


FROM centos                 //使用centos镜像

LABEL MAINTAINER='chen 1544060135@qq.com'             //打标签，你的基本信息

ADD files /usr/src

WORKDIR /usr/src/

RUN rm -rf /etc/yum.repos.d/* && 
    curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo &&

    ./configure --prefix=/usr/local/apr && make && make install && 
    cd ../apr-util-1.6.1 && 
    ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr &&

      --with-mpm=prefork && make && make install

EXPOSE 80           //写你要暴露的端口号一般只有80端口

VOLUME ["/usr/local/apache/htdocs/"]                //定义宿主机或其他容器的挂载点

CMD ["/usr/local/apache/bin/apachectl","-D","FOREGROUND"]            启动容器让apache在默认在前台运行

• 构建镜像

[root@cxr apache]# docker build -t chen1544060135/httpd:v0.1 /opt/apache/
[root@cxr apache]# docker images 
REPOSITORY              TAG       IMAGE ID       CREATED          SIZE
chen1544060135/httpd    v0.1      b81ac90ec490   53 minutes ago   717MB

• 用刚才制作的镜像创建容器

[root@cxr apache]# docker run -d -P --name httpd chen1544060135/httpd:v0.1
[root@cxr apache]# docker port httpd
80/tcp -> 0.0.0.0:49153
80/tcp -> :::49153

• 在浏览器上访问

• 上传镜像

[root@cxr apache]# docker push chen1544060135/httpd:v0.1
docker push chen1544060135/httpd:v0.1
394497b2c62e: Pushed 
394497b2c62e: Pushing  142.4MB/474.7MB
de8d6a4797f0: Layer already exists

[root@cxr apache]# 

• 在docker库查看
