I am building a custom Docker image from the official php-apache image but am failing to install the v8js PECL extension.
I've tried running the same commands I have used to install other PECL extensions, such as xdebug, but had no luck -- the build fails saying that I need to install the v8 distribution. I did try doing so using some Linux commands I googled around for, but I am not familiar with Linux at all, so really have no idea how to do this myself. Unfortunately the convenience scripts provided by the php-apache devs don't help in this case.
FROM php:7.3.4-apache
# Install v8js
RUN apt-get update && apt-get install -y libv8-3.14.5
RUN pecl install v8js-2.1.0 && docker-php-ext-enable v8js
# Install xdebug.
RUN pecl install xdebug-2.7.1 && docker-php-ext-enable xdebug
# Turn on mod_rewrite module for Apache.
RUN a2enmod rewrite
# Restart Apache.
RUN service apache2 restart
# Use the default development configuration.
RUN mv "$PHP_INI_DIR/php.ini-development" "$PHP_INI_DIR/php.ini"
Trying to build an image from the above Dockerfile, the libv8-3.14.5 package installs successfully, but the next line where I run pecl install... fails with the following output:
...
checking for V8 Javascript Engine... yes, shared
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
ERROR: Service 'web' failed to build: The command '/bin/sh -c pecl install v8js-2.1.0 && docker-php-ext-enable v8js' returned a non-zero code: 1
The xdebug extensions installs just fine, using the exact same command as you can see.
If anyone more familiar with Linux could help me out I'd appreciate the help.
