Answer 1

The 2019 way and probably the 2020 way of installing memcached to your Docker PHP container is the way described on https://hub.docker.com/_/php

FROM php:latest
RUN pecl install memcached \
    && docker-php-ext-enable memcached

FROM php:5.6-cli
RUN apt-get update && apt-get install -y libmemcached-dev zlib1g-dev \
    && pecl install memcached-2.2.0 \
    && docker-php-ext-enable memcached

Answer 2

You can achieve this with only 3 short lines of code. Here is an example for PHP7.4-FPM (Check the attached github link for guidance on other image variants and versions)

Dockerfile:

FROM php:7.4-fpm

COPY --from=mlocati/php-extension-installer /usr/bin/install-php-extensions /usr/bin/

RUN install-php-extensions mysqli pdo_mysql

As of the posting of this response the plugin supports up to 80 PHP Extensions which I find it supper amazing. You can get more info on this github repository

Answer 3

RUN docker-php-ext-install mbstring pdo pdo_mysql \

That code can do install any extension you want in this case mysql pdp driver but the Dockerfile should have base of FROM php:7.1.8-apache

Answer 4

Seems to be a bug in phpize (https://bugs.php.net/bug.php?id=53571).

I added the following to docker-php-ext-configure:

/usr/local/bin # diff -u docker-php-ext-configure.bak docker-php-ext-configure
--- docker-php-ext-configure.bak
+++ docker-php-ext-configure
@@ -54,5 +54,6 @@

 set -x
 cd "$ext"
+[[ ! -f "config.m4" && -f "config0.m4" ]] && mv config0.m4 config.m4
 phpize
 ./configure "$@"

I had the same problem a while ago. I started a container and typed the ext-install command into this container. Once I found all the dependencies, I wrote them into the Dockerfile.

Example:

RUN apt-get update && apt-get install -y \
libmcrypt-dev \
&& docker-php-ext-install -j$(nproc) mcrypt

There is a dependency that libmcrypt-dev needed before you can run docker-php-ext-install mcrypt

I've checked my older Dockerfiles and found something which might help you

FROM php:5.6-apache

RUN apt-get update && apt-get install -y \
        libfreetype6-dev \
        libjpeg62-turbo-dev \
        libmcrypt-dev \
        libpng12-dev \
    libicu-dev \
     libxml2-dev \
    vim \
        wget \
        unzip \
        git \
    && docker-php-ext-install -j$(nproc) iconv intl xml soap mcrypt opcache pdo pdo_mysql mysqli mbstring \
    && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
    && docker-php-ext-install -j$(nproc) gd
