Docker：无法安装 php intl extension when using php:fpm-alpine 官方镜像

Question

I am setting up very basic Docker container for a PHP and Zend framework project. I am using official Docker image php:fpm-alpine . Container is running successfully and I am able to see my application. In order for Zend to work I need PHP intl extention. When I add RUN docker-php-ext-install intl command in DockerFile extention is not installed successfully.

DockerFile code

FROM php:fpm-alpine

WORKDIR /usr/share/nginx/html

RUN docker-php-ext-install mysqli pdo pdo_mysql intl

Any help or recommendation is much appreciated. Thanks in advance.

Answer 1

The installation of intl extension is failing because a dependency is missing for it. Please update your Dockerfile with following and it should work.

FROM php:fpm-alpine    
WORKDIR /usr/share/nginx/html
RUN apk add icu-dev 
RUN docker-php-ext-install mysqli pdo pdo_mysql
RUN docker-php-ext-configure intl && docker-php-ext-install intl
