PHP&MySQL范例精解_创建、修改、重用-docker环境搭建-3.准备php-gd

准备php

拉取php镜像,因为书本是针对php5的,我们就不拉取7的了

docker pull php:5.6-fpm

选择这个php:5.6-fpm,而不是php:5.6-fpm-alpine3.8是想安装gd更方便点

创建临时容器

docker run -d --rm --name tmp-php-fpm php:5.6-fpm

进入容器

localhost:~ jjkkll$ bash -c "clear && docker exec -it tmp-php-fpm sh"

可以找到相应的目录,上次找到目录位置用的php:7.2.12-fpm-alpine3.8的镜像,发现这个位置是一样的.

/var/www/html
/usr/local/etc/

将配置放到容器外

若要将配置放到容器外,可以在容器外,拷贝容器里的配置

docker cp tmp-php-fpm:/usr/local/etc/  /Users/jjkkll/Documents/2020-book-read/7302195625/docker/php-5.6-fpm-etc/

可以在相应目录下看到配置已经拷贝到外面了

localhost:~ jjkkll$ tree -N /Users/jjkkll/Documents/2020-book-read/7302195625/docker/php-5.6-fpm-etc/
/Users/jjkkll/Documents/2020-book-read/7302195625/docker/php-5.6-fpm-etc/
└── etc
    ├── pear.conf
    ├── php
    │   ├── conf.d
    │   ├── php.ini-development
    │   └── php.ini-production
    ├── php-fpm.conf

    └── php-fpm.d
        ├── docker.conf
        ├── www.conf
        └── zz-docker.conf

启动时docker run命令里加上-v参数指定即可:

-v /Users/jjkkll/Documents/2020-book-read/7302195625/docker/php-5.6-fpm-etc/etc/:/usr/local/etc/

制作包含gd的镜像

准备sources.list

国内更新包的速度太慢,改成163的镜像:

/Users/jjkkll/Documents/2020-book-read/7302195625/docker/php-5.6-fpm-gd/sources.list,文件内容:

deb http://mirrors.163.com/debian/ stretch main non-free contrib
deb http://mirrors.163.com/debian/ stretch-updates main non-free contrib
deb http://mirrors.163.com/debian/ stretch-backports main non-free contrib
deb-src http://mirrors.163.com/debian/ stretch main non-free contrib
deb-src http://mirrors.163.com/debian/ stretch-updates main non-free contrib
deb-src http://mirrors.163.com/debian/ stretch-backports main non-free contrib
deb http://mirrors.163.com/debian-security/ stretch/updates main non-free contrib
deb-src http://mirrors.163.com/debian-security/ stretch/updates main non-free contrib

Dockerfile

准备Dockerfile文件

/Users/jjkkll/Documents/2020-book-read/7302195625/docker/php-5.6-fpm-gd/Dockerfile,文件内容:

FROM php:5.6-fpm
COPY Dockerfile /
COPY sources.list /
RUN  mv /etc/apt/sources.list /etc/apt/sources.list.bak && mv /sources.list /etc/apt/
RUN apt-get update && apt-get install -y \
        libfreetype6-dev \
        libjpeg62-turbo-dev \
        libpng-dev \
    && docker-php-ext-configure gd --with-freetype --with-jpeg \
    && docker-php-ext-install -j$(nproc) gd

进入目录,创建镜像

docker build -t php-5.6-fpm-gd ./Dockerfile-php-5.6-fpm-gd
