Docker php—install php extensions ssh2

I am using the official php docker image as base for my application container, so the Dockerfile starts like so: 

FROM php:5.6-fpm-jessie

Later in the file I would like to have something like that: 

 RUN apt-get update \
    && apt-get install -y libssh2-1-dev libssh2-1 \
    && docker-php-ext-install ssh2

But that tells me:

/usr/src/php/ext/ssh2 does not exist

So since that is a debian (yessie) based image, only the old php5 packages are available and php7 is installed by some tricky script in the php:fpm dockerfile and it seams that all extensions are compiled within the used php executable.

How can I install more extensions in this scenario?

The easiest solution is to use install-php-extensions. It's a script that can install the required system libraries automatically, on any Docker PHP image.

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

RUN install-php-extensions ssh2

install-php-extensions can install a ton of other PHP extensions as well, not only ssh2: more details at https://github.com/mlocati/docker-php-extension-installer

In case you are using PHP >=8.0 image:

FROM php:8.0.2-fpm

RUN apt-get install -y libssh2-1-dev libssh2-1 \
    && pecl install ssh2-1.3.1 \
    && docker-php-ext-enable ssh2

The solution that worked for me on the CLI image of PHP 7.2:

FROM php:7.2-cli

RUN apt-get install -y libssh2-1 libssh2-1-dev
RUN pecl install ssh2-1.2 && docker-php-ext-enable ssh2

Build the Docker image and confirm the SSH2 extension is installed:

docker build -t example/php-build .
docker run --rm example/php-build php --ri ssh2

ssh2

SSH2 support => enabled
extension version => 1.2
libssh2 version => 1.8.0
banner => SSH-2.0-libssh2_1.8.0

For someone looking for a newer version of this for php 7.4 you'll need the following:

install dependencies

RUN apt-get update && apt-get install -y \
    ssh \
    libssh2-1 \
    libssh2-1-dev \
    wget \
    libssl-dev \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/*

# Install ssh2 extension

RUN wget -O libssh2.tar.gz https://www.libssh2.org/download/libssh2-1.9.0.tar.gz \
    && wget -O ssh2.tgz https://pecl.php.net/get/ssh2-1.2.tgz \
    && mkdir libssh2 && tar vxzf libssh2.tar.gz -C libssh2 --strip-components 1 \
    && mkdir ssh2 && tar vxzf ssh2.tgz -C ssh2 --strip-components 1 \
    && cd libssh2 && ./configure \
    && make && make install \
    && cd ../ssh2 && phpize && ./configure --with-ssh2 \
    && make && make install \
    && echo "extension=ssh2.so" >> /usr/local/etc/php/conf.d/ssh2.ini \
    && cd ../ && rm -rf libssh2.tar.gz ssh2.tgz ssh2 libssh2

The links posted here will only work up to php 7.2.

It looks like the pecl option isn't available for anything newer then PHP 6. In order to get it installed, I had to build from source. From php:7.1.27-cli I was able to get it setup with these commands - the php:7.1.27-cli image is based on debian stretch:

# install dependencies 
RUN apt-get update && apt-get install -y \
    ssh \
    libssh2-1 \
    libssh2-1-dev \
    wget \
    libssl-dev \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/*

# Install ssh2 extension
RUN wget -O libssh2.tar.gz https://www.libssh2.org/download/libssh2-1.8.1.tar.gz \
    && wget -O ssh2.tgz https://pecl.php.net/get/ssh2-1.1.2.tgz \
    && mkdir libssh2 && tar vxzf libssh2.tar.gz -C libssh2 --strip-components 1 \
    && mkdir ssh2 && tar vxzf ssh2.tgz -C ssh2 --strip-components 1 \
    && cd libssh2 && ./configure \
    && make && make install \
    && cd ../ssh2 && phpize && ./configure --with-ssh2 \
    && make && make install \
    && echo "extension=ssh2.so" >> /usr/local/etc/php/conf.d/ssh2.ini \
    && cd ../ && rm -rf libssh2.tar.gz ssh2.tgz ssh2 libssh2

Finally, this is successful. 

&& apt-get install -y libssh2-1-dev libssh2-1 \
&& pecl install ssh2 \
&& docker-php-ext-enable ssh2
