用php5.6安装debian stretch

Question

We are using laravel based on php version 5.6, few days ago Debian removed jessie version (8) so we need to upgrade that to 9, but the issue is its hard to use Debian 9 without php5.6 as scripts like docker-php-ext-install does not seem to work there. i attach my section of the installation in the docker-file. Would appreciate if there is a solution to this

I have tried to install the pdo_mysql without the docker-php-ext-install but it fails cannot locate that..

FROM debian:9.0
RUN apt-get update \
&& apt-get -y install \
    apt-transport-https apt-utils \
    lsb-release \
    ca-certificates \
    wget \
    mcrypt \
    libmcrypt-dev \
    git-core \
    unzip \
&& wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg \
&& echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/php.list \
&& apt-get update \
&& apt-get -y install gnupg2 php5.6-cli php5.6-fpm \
&& apt-get update \
&& docker-php-ext-install \
    mbstring \
    pdo_mysql \
    mcrypt bcmath\
&& update-alternatives --install /usr/bin/php php /usr/bin/php5.6 90 \
&& update-alternatives --set php /usr/bin/php5.6

And this is the end of the build call :

Reading package lists...
/bin/sh: 1: docker-php-ext-install: not found

Answer 1

docker-php-ext-install is a command provided by official php images. You will find it only on those images or images based on those.

Official docker php images providing php 5.6 still exist on the docker hub:

wget -qO- https://registry.hub.docker.com/v1/repositories/php/tags | jq '.[].name' | grep -P '^"5\.6(?!\.)'

 "5.6" "5.6-alpine" "5.6-alpine3.4" "5.6-alpine3.7" "5.6-alpine3.8" "5.6-apache" "5.6-apache-jessie" "5.6-apache-stretch" "5.6-cli" "5.6-cli-alpine" "5.6-cli-alpine3.4" "5.6-cli-alpine3.7" "5.6-cli-alpine3.8" "5.6-cli-jessie" "5.6-cli-stretch" "5.6-fpm" "5.6-fpm-alpine" "5.6-fpm-alpine3.4" "5.6-fpm-alpine3.7" "5.6-fpm-alpine3.8" "5.6-fpm-jessie" "5.6-fpm-stretch" "5.6-jessie" "5.6-stretch" "5.6-zts" "5.6-zts-alpine" "5.6-zts-alpine3.4" "5.6-zts-alpine3.7" "5.6-zts-alpine3.8" "5.6-zts-jessie" "5.6-zts-stretch" 

Furthermore, those images are built on top of debian 9:

docker run --rm php:5.6 cat /etc/os-release

 PRETTY_NAME="Debian GNU/Linux 9 (stretch)" NAME="Debian GNU/Linux" VERSION_ID="9" VERSION="9 (stretch)" ID=debian HOME_URL="https://www.debian.org/" SUPPORT_URL="https://www.debian.org/support" BUG_REPORT_URL="https://bugs.debian.org/" 

and provide the docker-php-ext-install command:

docker run --rm php:5.6 which docker-php-ext-install

 /usr/local/bin/docker-php-ext-install 

---

I suggest you use one of those official image as the base for your Dockerfile.

FROM php:5.6-fpm
RUN apt-get update \
    && apt-get -y install \
        libmcrypt-dev \
        mcrypt \
    && docker-php-ext-install \
        bcmath \
        mbstring \
        mcrypt \
        pdo_mysql
