PHP Docker install pecl V8JS (Debian Buster) - php

Question

I tried to install V8JS with this Dockerfile
FROM php:7.3-cli-buster
RUN apt-get update -y --fix-missing && apt-get upgrade -y;
# Install v8js
RUN apt-get install -y libv8-dev
RUN pecl install v8js
RUN docker-php-ext-enable v8js
but I got a configuration error:
checking for V8 files in default path... not found
configure: error: Please reinstall the v8 distribution ERROR:
`/tmp/pear/temp/v8js/configure
--with-php-config=/usr/local/bin/php-config --with-v8js' failed The command '/bin/sh -c pecl install v8js' returned a non-zero code: 1
full cli output:

How to resolve configuration error (due to lack of a path to the V8 files I guess) and install V8JS on PHP Docker FROM Debian Buster?
EDIT
Dockerfile from #saulotoledo answer works :)
Building image takes approx 60-90 min and the image size is 5.47GB vs base image (FROM) 7.3-cli-buster 367MB
to build Dockerfile php with V8JS copy the code from #saulotoledo answer and paste it into the file named Dockerfile
Then run in the same directory this command:
docker build --tag "test-php-js" .
Then run container this way:
docker run -it --rm --entrypoint="" --name="php-v8js" test-php-js /bin/sh
you should be logged into terminal of php-cli, type:
php -m
and you should see a list of enabled extensions including v8js
type:
php --ri v8js
to see some details, something like:
V8 Javascript Engine => enabled
V8 Engine Compiled Version => 7.4.288.21
V8 Engine Linked Version => 7.4.288.21
Version => 2.1.1
and now the cherry part you all have been waiting for - type:
php -r "(new V8Js())->executeString(\"print('Hello' + ' from JS ' + 'World!')\", 'basic.js');";
to see php running js code with V8JS support :D
Hello from JS World!
Note that I needed to put extra backslash \ in front of every JS doublequote " for the php -r command. But that's only due to running JS from php in cli mode as oneliner.
Normally you don't need that
See an official PHP documentation example
Does anyone know if it is possible to install and enable V8JS extension without building it from its source but by using Debian Buster package and PECL as I tried at the beginning?

Answer 1

Edit:
That should solve your issue (note that I am compiling it manually):
FROM php:7.3-cli-buster
ENV V8_VERSION=7.4.288.21
RUN apt-get update -y --fix-missing && apt-get upgrade -y;
# Install v8js (see https://github.com/phpv8/v8js/blob/php7/README.Linux.md)
RUN apt-get install -y --no-install-recommends \
libtinfo5 libtinfo-dev \
build-essential \
curl \
git \
libglib2.0-dev \
libxml2 \
python \
patchelf \
&& cd /tmp \
\
&& git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git --progress --verbose \
&& export PATH="$PATH:/tmp/depot_tools" \
\
&& fetch v8 \
&& cd v8 \
&& git checkout $V8_VERSION \
&& gclient sync \
\
&& tools/dev/v8gen.py -vv x64.release -- is_component_build=true use_custom_libcxx=false
RUN export PATH="$PATH:/tmp/depot_tools" \
&& cd /tmp/v8 \
&& ninja -C out.gn/x64.release/ \
&& mkdir -p /opt/v8/lib && mkdir -p /opt/v8/include \
&& cp out.gn/x64.release/lib*.so out.gn/x64.release/*_blob.bin out.gn/x64.release/icudtl.dat /opt/v8/lib/ \
&& cp -R include/* /opt/v8/include/ \
&& apt-get install patchelf \
&& for A in /opt/v8/lib/*.so; do patchelf --set-rpath '$ORIGIN' $A;done
# Install php-v8js
RUN cd /tmp \
&& git clone https://github.com/phpv8/v8js.git \
&& cd v8js \
&& phpize \
&& ./configure --with-v8js=/opt/v8 LDFLAGS="-lstdc++" \
&& make \
&& make test \
&& make install
RUN docker-php-ext-enable v8js
Old answer:
I believe you need to compile the V8 manually. I am not sure yet why the libv8-dev is not enough. Since that does not work, you need to compile it because it is a requirement.
That said, this link may be helpful. But the official compilation instructions are presented here. After a few tests I noticed you need to add libtinfo5 (and maybe libtinfo-dev, to be safe, but you may try it without it) to your apt-get install, otherwise the ninja build in the instructions will fail.
After using that compilation instructions in your Dockerfile, the V8 will compile properly. After that you will still have some trouble with the pecl installation. Unfortunately I had to stop investigating the problem for now, the compilation takes some time. However, the following links may help you to solve your problem:
This one if you still have trouble compiling with ninja
This one presents another Dockerfile for compiling V8, but the base image is different and needs some adaptation.
I hope it helps. If you manage to have a working Dockerfile please share with us later. If I have some time later to investigate it and I have some progress I will edit my answer.

Answer 2

Thanks to saulotoledo I created example image that takes 950MB vs 398MB base image (php:7.3-cli-buster)
It works also with PHP FPM, just change
FROM php:7.3-cli-buster to FROM php:7.3-fpm-buster if you want FPM version.
Dockerfile
FROM php:7.3-cli-buster
ENV V8_VERSION=7.4.288.21
# php:7.3-cli-buster 398MB
RUN apt-get update -y --fix-missing && apt-get upgrade -y;
# Install required CLI tools
RUN apt-get install -y --no-install-recommends \
libtinfo5 libtinfo-dev \
build-essential \
curl \
git \
libglib2.0-dev \
libxml2 \
python \
patchelf
# Install V8, PHP's V8Js
RUN cd /tmp \
\
&& git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git --progress --verbose \
&& export PATH="$PATH:/tmp/depot_tools" \
\
&& fetch v8 \
&& cd v8 \
&& git checkout $V8_VERSION \
&& gclient sync \
&& tools/dev/v8gen.py -vv x64.release -- is_component_build=true use_custom_libcxx=false \
\
&& cd /tmp/v8 \
&& ninja -C out.gn/x64.release/ \
&& mkdir -p /opt/v8/lib && mkdir -p /opt/v8/include \
&& cp out.gn/x64.release/lib*.so out.gn/x64.release/*_blob.bin out.gn/x64.release/icudtl.dat /opt/v8/lib/ \
&& cp -R include/* /opt/v8/include/ \
&& for A in /opt/v8/lib/*.so; do patchelf --set-rpath '$ORIGIN' $A;done \
\
&& cd /tmp \
&& git clone https://github.com/phpv8/v8js.git \
&& cd v8js \
&& phpize \
&& ./configure --with-v8js=/opt/v8 LDFLAGS="-lstdc++" \
&& make \
&& make test \
&& make install \
\
&& docker-php-ext-enable v8js \
\
&& rm -rf "/tmp/v8" \
&& rm -rf "/tmp/depot_tools"
# Image size after removing source files 950MB

This works without compiling v8 - it is very fast. Using distro packaged nodejs library. You can use current official php docker image
RUN apt-get install -y libnode-dev \
&& cp -s /usr/lib/x86_64-linux-gnu/libv8* /usr/local/lib/ \
&& cp -rs /usr/include/node/* /usr/local/include/ \
&& pecl install v8js \
&& echo "extension=v8js.so" > /usr/local/etc/php/conf.d/v8js.so
