查找 上的 httpd 镜像:

可以通过 Sort by 查看其他版本的 httpd,默认是最新版本 httpd:latest。
此外,我们还可以用 docker search httpd 命令来查看可用版本:
- xxx@xxx:~/apache$ docker search httpd
- NAME DESCRIPTION STARS OFFICIAL AUTOMATED

这里我们拉取官方的镜像
xxx@xxx:~/apache$ docker pull httpd
等待下载完成后,我们就可以在本地镜像列表里查到REPOSITORY为httpd的镜像。
- xxx@xxx:~/apache$ docker images httpd
- REPOSITORY TAG IMAGE ID CREATED SIZE

创建 Dockerfile
首先,创建目录apache,用于存放后面的相关东西。
xxx@xxx:~$ mkdir -p ~/apache/www ~/apache/logs ~/apache/conf
www 目录将映射为 apache 容器配置的应用程序目录。
logs 目录将映射为 apache 容器的日志目录。
conf 目录里的配置文件将映射为 apache 容器的配置文件。
进入创建的 apache 目录,创建 Dockerfile。

- COPY httpd-foreground /usr/local/bin/
- EXPOSE 80
- CMD ["httpd-foreground"]
Dockerfile文件中 COPY httpd-foreground /usr/local/bin/ 是将当前目录下的httpd-foreground拷贝到镜像里,作为httpd服务的启动脚本,所以我们要在本地创建一个脚本文件httpd-foreground
#!/bin/bashset -e# Apache gets grumpy about PID files pre-existingrm -f /usr/local/apache2/logs/httpd.pidexec httpd -DFOREGROUND
赋予 httpd-foreground 文件可执行权限。
xxx@xxx:~/apache$ chmod +x httpd-foreground
通过 Dockerfile 创建一个镜像,替换成你自己的名字。
xxx@xxx:~/apache$ docker build -t httpd .
创建完成后,我们可以在本地的镜像列表里查找到刚刚创建的镜像。
- xxx@xxx:~/apache$ docker images httpd

docker run -p 80:80 -v $PWD/www/:/usr/local/apache2/htdocs/ -v $PWD/conf/httpd.conf:/usr/local/apache2/conf/httpd.conf -v $PWD/logs/:/usr/local/apache2/logs/ -d httpd
命令说明:
-p 80:80: 将容器的 80 端口映射到主机的 80 端口。
-v $PWD/www/:/usr/local/apache2/htdocs/: 将主机中当前目录下的 www 目录挂载到容器的 /usr/local/apache2/htdocs/。
-v $PWD/conf/httpd.conf:/usr/local/apache2/conf/httpd.conf: 将主机中当前目录下的 conf/httpd.conf 文件挂载到容器的 /usr/local/apache2/conf/httpd.conf。
-v $PWD/logs/:/usr/local/apache2/logs/: 将主机中当前目录下的 logs 目录挂载到容器的 /usr/local/apache2/logs/。
查看容器启动情况:
- xxx@xxx:~/apache$ docker ps
