How to install LDAP in Docker php-fpm alpine - php

Question

any idea how can i install the php Ldap extension in dockerfile
FROM php:7.2-fpm-alpine
i tried the following
RUN docker-php-ext-configure ldap --prefix=/usr/local/php --with-ldap=/usr/lib/i386-linux-gnu
RUN docker-php-ext-install ldap
but when i build docker , i get the error message
configure: error: Cannot find ldap.h
ERROR: Service 'php' failed to build: The command '/bin/sh -c docker-php-ext-install ldap' returned a non-zero code: 1
PS: it is alpine so 'apt-get' wont work here, instead 'apk add'

Answer 1

If you are experiencing configure: error: Cannot find ldap.h
try to add this line in your Alpine based Dockerfile
RUN apk add ldb-dev libldap openldap-dev

Answer 2

You need to use openldap-dev to have the ldap.h file to install ldap with the docker-php-ext-install script.
Something like this works:
FROM php:8.0.2-fpm-alpine
RUN apk update \
&& apk add --no-cache --virtual .build-dependencies-in-virtual-world openldap-dev \
&& docker-php-ext-install ldap \
&& docker-php-ext-enable ldap \
&& apk del .build-dependencies-in-virtual-world
For me, I used this my Laravel project:
My Dockerfile for a Laravel app
I had to use line 5 because id get this if I don't:
Undefined constant "LdapRecord\Models\Attributes\LDAP_ESCAPE_FILTER"

This is working for me:
FROM php:7.4.9-fpm-alpine3.12
COPY --from=mlocati/php-extension-installer /usr/bin/install-php-extensions /usr/bin/
# Install PHP extensions
RUN install-php-extensions ldap

fixed with the following dockerfile :
FROM php:7.2-fpm-alpine
# Install composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
# lumen packages
RUN apk add openldap-back-mdb

RUN docker-php-ext-install intl soap
RUN docker-php-ext-install mbstring tokenizer mysqli pdo_mysql json hash iconv
RUN apk --update --no-cache add php7-ldap libldap php-ldap openldap-clients openldap openldap-back-mdb
RUN apk add --no-cache ldb-dev

#RUN docker-php-ext-configure ldap --prefix=/usr/local/php --with-ldap=/usr/lib/libldap.so

ARG DOCKER_PHP_ENABLE_LDAP
RUN echo -n "With ldap support: " ; if [[ "${DOCKER_PHP_ENABLE_LDAP}" = "on" ]] ; then echo "Yes"; else echo "No" ; fi && \

# Enable LDAP
RUN if [ "${DOCKER_PHP_ENABLE_LDAP}" != "off" ]; then \
# Dependancy for ldap \
apk add --update --no-cache \
libldap && \
# Build dependancy for ldap \
apk add --update --no-cache --virtual .docker-php-ldap-dependancies \

docker-php-ext-configure ldap && \
docker-php-ext-install ldap && \

else \

You can try the ldb-dev alpine package.`
FROM php:7.2-fpm-alpine
RUN apk add --no-cache ldb-dev
