PHP官方docker镜像分类

• php:-cli
  

• php:-apache
  

• php:-fpm
  

• php:-alpine
  

制定适合生产环境的镜像

为何要定制

官方镜像缺少常见扩展 以php:8.0.8-fpm-alpine3.13为例

定制步骤

• 新建目录
  以/root/docker为例
  mkdir php/conf.d -p
  新建Dockerfile 输入

FROM php:8.0.8-fpm-alpine3.13

LABEL maintainer="leo leo2768@163.com"

# 设置apk源为国内镜像源
RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.ustc.edu.cn/g' /etc/apk/repositories
COPY ./conf.d/ $PHP_INI_DIR/conf.d/

ENV TZ "Asia/Shanghai"
ENV TERM xterm
# 默认关闭opcode
ENV OPCODE 0

# 添加用户
RUN addgroup -g 1000 -S www && adduser -s /sbin/nologin -S -D -u 1000 -G www www
# 指定扩展版本
ENV PHPREDIS_VERSION 5.3.4

# 拷贝配置文件
COPY  www.conf /usr/local/etc/php-fpm.d/www.conf

RUN mv "$PHP_INI_DIR/php.ini-production" "$PHP_INI_DIR/php.ini"

新建www.conf 输入

[www]
user = www
group = www
listen = 0.0.0.0:9000
pm = dynamic
pm.max_children = 6
pm.start_servers = 4
pm.min_spare_servers = 1
pm.max_spare_servers = 5

在conf.d下新建date.ini 输入

date.timezone = Asia/Shanghai

在conf.d下新建opcode.ini 输入

opcache.enable= 0
enable_clopcache.enable_cli=1
opcache.revalidate_freq=60
opcache.max_accelerated_files=100000
opcache.validate_timestamps=1

新建build.sh 输入

#/bin/bash
docker build -t php8-swoole-yaf-redis-amqp:latest .

目录结构如下：

.
|-- build.sh
|-- conf.d
|   |-- date.ini
|   `-- opcode.ini
|-- Dockerfile
`-- www.conf

执行sh build.sh
结果：
