这篇文章将为大家详细讲解有关Dockerfile中怎么构建一个PHP镜像，文章内容质量较高，因此小编分享给大家做个参考，希望大家阅读完这篇文章后对相关知识有一定的了解。

1 搭建私有镜像仓库

1) 拉起镜像仓库docker run -d \-v /opt/registry:/var/lib/registry \-p 5000:5000 \--restart=always \--name registry \registry2）修改配置仓库是之能够被我们使用vi /etc/docker/daemon.json{"registry-mirrors": ["http://04be47cf.m.daocloud.io"],"insecure-registries":["192.168.184.130:5000"]}systemctl daemon-reload systemctl restart docker  3）测试仓库是否可用curl http://192.168.184.130:5000/v2/_catalog{"repositories":[]} 说明成功

2 创建镜像构建目录

mkdir /tmp/php

3 下载php软件包

wget http://cn2.php.net/distributions/php-7.1.5.tar.gz -P /tmp/php

4 编写Dockerfile文件

cd /tmp/phpcat Dockerfile FROM centos:7MAINTAINER swiftRUN yum install -y install epel-release && \    yum -y install git wget lrzsz vim  libxml2 libxml2-devel openssl openssl-devel curl curl-devel libjpeg-turbo libjpeg-turbo-devel libpng-devel libpng freetype-devel freetype icu libicu-devel libicu libmcrypt libmcrypt-devel libxslt libxslt-devel php-mysql && \    yum -y groupinstall "Development Tools" && \    yum provides "*/applydeltarpm" && \     yum install deltarpm -y && \       yum clean all && \    groupadd www && \    useradd -g www www   ADD php-7.1.5.tar.gz   /usr/local/src/RUN cd /usr/local/src/php-7.1.5 && \    ./configure --prefix=/usr/local/php71 \    --with-config-file-path=/usr/local/php71/etc \    --with-config-file-scan-dir=/usr/local/php71/conf.d \    --enable-fpm --with-fpm-user=www \    --with-fpm-group=www \    --with-mysql=mysqlnd \    --with-mysqli=mysqlnd \    --with-pdo-mysql=mysqlnd \    --with-iconv-dir \    --with-freetype-dir=/usr/local/freetype \    --with-jpeg-dir \    --with-png-dir \    --with-zlib \    --with-libxml-dir=/usr \    --enable-xml \    --disable-rpath \    --enable-bcmath \    --enable-shmop \    --enable-sysvsem \    --enable-inline-optimization \    --with-curl \    --enable-mbregex \    --enable-mbstring \    --with-mcrypt \     --enable-ftp \    --with-gd \    --enable-gd-native-ttf \    --with-openssl \    --with-mhash \    --enable-pcntl \    --enable-sockets \    --with-xmlrpc \    --enable-zip \    --enable-soap \    --with-gettext \    --disable-fileinfo \    --enable-opcache \    --enable-intl \    --with-xsl && \    make -j 4 && make install && \    cp /usr/local/php71/etc/php-fpm.conf.default /usr/local/php71/etc/php-fpm.conf && \    cp ./php.ini-production  /usr/local/php71/etc/php.ini && \    cp /usr/local/php71/etc/php-fpm.d/www.conf.default /usr/local/php71/etc/php-fpm.d/www.conf && \    cp ./sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm && \    chmod +x /etc/init.d/php-fpm && \    rm -rf /usr/loacl/src/php-7.1.5EXPOSE 9000CMD ["/etc/init.d/php-fpm","start"]

5 构建php镜像

docker build -t 192.168.184.130:5000/lnmp-7-php71:base .

6 查看查看已经构建的镜像并上传到私有仓库

1）查看镜像# docker imagesREPOSITORY                           TAG                 IMAGE ID            CREATED             SIZE192.168.184.130:5000/lnmp-7-php71    base                9c85344d010f        8 minutes ago       1.26GB2）给镜像打tagdocker tag  192.168.184.130:5000/lnmp-7-php71:base 192.168.184.130:5000/lnmp-7-php71:v33）上传到私有仓库docker push 192.168.184.130:5000/lnmp-7-php71:v34）查看镜像仓库 curl http://192.168.184.130:5000/v2/lnmp-7-php71/tags/list{"name":"lnmp-7-php71","tags":["base","v3","redis","redisv1","redisv2"]}

7 测试使用镜像

1) run起来一个phpdocker run -d -p 9000:9000 --name php-test 192.168.184.130:5000/lnmp-7-php71:v32）查看docker是否运行# docker ps | grep php-test5ad6cbbaf728        192.168.184.130:5000/lnmp-7-php71:v3   "/bin/sh -c '/etc/in…"   5 minutes ago       Up 5 minutes        0.0.0.0:9000->9000/tcp, 9006/tcp   php-test3）查看端口# ss -anlptu | grep 9000tcp    LISTEN     0      128      :::9000                 :::*                   users:(("docker-proxy",pid=7340,fd=4))4）查看日志# docker logs php-test -fStarting php-fpm  done

8 添加redis扩展

1）创建php-redisDocker文件目录#mkdir redis2) 以php-test 192.168.184.130:5000/lnmp-7-php71:v3为基础镜像添加redis扩展# cat Dockerfile FROM 192.168.184.130:5000/lnmp-7-php71:v3MAINTAINER swiftRUN cd /usr/local/src && \    git clone https://github.com/phpredis/phpredis.git phpredis71 && \    cd phpredis71 && \    /usr/local/php71/bin/phpize && \    ./configure  --with-php-config=/usr/local/php71/bin/php-config && \    make && make install 3) build镜像#docker build -t 192.168.184.130:5000/lnmp-7-php71:redis .4）给镜像打tag#docker tag 192.168.184.130:5000/lnmp-7-php71:redis 192.168.184.130:5000/lnmp-7-php71:redisv25）上传到私有仓库#docker push 192.168.184.130:5000/lnmp-7-php71:redisv26）创建php.ini配置文件#cat php.iniextension=redis.so7）创建测试容器验证#docker run -d -p 9006:9000 -v /root/redis/php.ini:/usr/local/php71/etc/php.ini --name php-test-redis 192.168.184.130:5000/lnmp-7-php71:redisv28）查看redis模块是否加载#docker exec -it php-test-redis bash -c  '/usr/local/php71/bin/php -m  | grep redis'redis##############################################################################################################################kill -USR2 ps -ef | grep php-fpm | grep 'master process' | grep '/usr/local/php71/etc/php-fpm.conf' | awk -F ' ' '{print $2}'###############################################################################################################################
