SSL error while connecting to MongoDB Atlas on Alpine builds

[pukkancs]

Hi,

we are getting the below issue on the alpine image:

Fatal error: Uncaught MongoDB\Driver\Exception\InvalidArgumentException: Cannot create SSL client. SSL is not enabled in this build. in /var/www/myproject/vendor/mongodb/mongodb/src/Client.php:87

using

FROM php:7.2-fpm-alpine
WORKDIR /var/www

RUN apk add --no-cache --virtual .ext-deps \
        autoconf \
        g++ \
        make \
	pkgconf \
	libssl1.0 \
    && pecl install \
        redis \
        mongodb \
    && docker-php-ext-enable \
        redis \
        mongodb \
    && apk del .ext-deps

RUN pecl config-set php_ini /etc/php.ini

# Copy project files
COPY . /var/www/myproject/

We also tried without libssl1.0 as libressl seem to install it on the base build and several other things without being able to solve this.

Works fine on 7.2-fpm-stretch

FROM php:7.2-fpm-stretch
WORKDIR /var/www

RUN apt-get update && apt-get install --no-install-recommends -y \
        g++ \
        pkg-config \
        libssl-dev \
    && pecl install \
       mongodb \
       redis \
    && docker-php-ext-enable \
       mongodb \
       redis \
    && pecl config-set php_ini /etc/php.ini \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/*

# Copy project files
COPY . /var/www/myproject/

This is an error output by MongoDB doctrine/DoctrineMongoDBBundle#452 (comment)

The exception with message "Cannot create SSL client. SSL is not enabled in this build." originates in phongo_manager_init() when MONGOC_ENABLE_SSL is not defined.

 

FriendsOfSymfony/FOSUserBundle#2786

with apt-get install php7.2-mongodb it install it correctly with SSL and other options enabled.

 

If you have further questions you should ask the Docker Community Forums, the Docker Community Slack, or Stack Overflow. As these repositories are for issues with the image and not necessarily for questions of usability

libssl1.0 in Alpine is just the shared library (ie needed at runtime), and not the development headers needed for linking. From the output of pecl install mongodb:

configure: checking whether OpenSSL is available
checking for PHP_MONGODB_SSL... no
checking for EVP_DigestInit_ex in -lcrypto... no
configure: checking whether OpenSSL >= 1.1.0 is available
checking for OPENSSL_init_ssl in -lssl... no
configure: checking whether OpenSSL < 1.1.0 is available
checking for SSL_library_init in -lssl... no
configure: checking whether LibreSSL is available
checking for PHP_MONGODB_SSL... no
checking for EVP_DigestInit_ex in -lcrypto... no
checking for tls_init in -ltls... no
checking which TLS library to use... no
checking whether to use system crypto profile... no
checking deprecated option for whether to use system crypto profile... no

So swapping libssl1.0 to openssl-dev:

configure: checking whether OpenSSL is available
checking for PHP_MONGODB_SSL... yes

And you'll want to make sure libssl1.0 stays installed and not removed as a dependency of openssl-dev with the apk del .ext-deps.
