docker php7.2-fpm can't install imap module

Question

I\'m having problems trying to get imap working with my docker-compose.

Here is what my php dockerfile looks like.

FROM php:7.2-fpm

RUN apt-get upda         


        

Answer 1

Actual in 2020 for PHP 7.4 and PHP 8 on Linux Alpine

RUN apk add imap-dev krb5-dev
RUN docker-php-ext-configure imap --with-kerberos --with-imap-ssl \
        && docker-php-ext-install imap \
        && docker-php-ext-enable imap

Here is a PHP 7 cli working answer, posted on the official library here

FROM php:7-cli-alpine

RUN set -xe && \
    apk add --update --no-cache \
        imap-dev \
        openssl-dev \
        krb5-dev && \
    (docker-php-ext-configure imap --with-kerberos --with-imap-ssl) && \
    (docker-php-ext-install imap > /dev/null) && \
    php -m | grep -F 'imap'
