How to enable HTTP/2 for CLOUD RUN app [php-apache] .

My docker file :

FROM php:8.1.0-apache

RUN a2enmod rewrite

RUN docker-php-ext-install mysqli pdo pdo_mysql

# Install system dependencies for GD with WebP support
RUN apt-get update && apt-get install -y \
    libjpeg-dev \
    libpng-dev \
    libwebp-dev \
    && rm -rf /var/lib/apt/lists/*
# Configure and install the GD extension with WebP support
RUN docker-php-ext-configure gd --with-jpeg --with-webp
RUN docker-php-ext-install -j$(nproc) gd

RUN docker-php-ext-install -j "$(nproc)" opcache

RUN set -ex; \
 { \
    echo "; Cloud Run enforces memory & timeouts"; \
    echo "memory_limit = 256M"; \
    echo "max_execution_time = 0"; \
    echo "; File upload at Cloud Run network limit"; \
    echo "upload_max_filesize = 128M"; \
    echo "post_max_size = 128M"; \
    echo "max_file_uploads = 200"; \
    echo "; Configure Opcache for Containers"; \
    echo "opcache.enable = On"; \
    echo "opcache.validate_timestamps = Off"; \
    echo "; Configure Opcache Memory (Application-specific)"; \
    echo "opcache.memory_consumption = 256"; \
 } > "$PHP_INI_DIR/conf.d/cloud-run.ini"

# Copy in custom code from the host machine.
WORKDIR /var/www/html
COPY . .

RUN chown -R www-data:www-data /var/www/html/

RUN sed -i 's/80/${PORT}/g' /etc/apache2/sites-available/000-default.conf /etc/apache2/ports.conf

RUN mv "$PHP_INI_DIR/php.ini-development" "$PHP_INI_DIR/php.ini"

Server name : YOUR-SERVICE-NAME-YOUR-PROJECT-ID.run.app

use this:

`FROM php:8.1.0-apache

RUN a2enmod rewrite

RUN docker-php-ext-install mysqli pdo pdo_mysql

RUN apt-get update && apt-get install -y
libjpeg-dev
libpng-dev
libwebp-dev
&& rm -rf /var/lib/apt/lists/*

RUN docker-php-ext-configure gd --with-jpeg --with-webp
RUN docker-php-ext-install -j$(nproc) gd

RUN docker-php-ext-install -j "$(nproc)" opcache

RUN set -ex;
{
echo "memory_limit = 256M";
echo "max_execution_time = 0";
echo "upload_max_filesize = 128M";
echo "post_max_size = 128M";
echo "max_file_uploads = 200";
echo "opcache.enable = On";
echo "opcache.validate_timestamps = Off";
echo "opcache.memory_consumption = 256";
} > "$PHP_INI_DIR/conf.d/cloud-run.ini"

WORKDIR /var/www/html
COPY . .

RUN chown -R www-data:www-data /var/www/html/

Set Apache to listen on Cloud Run $PORT

RUN echo "Listen ${PORT}" > /etc/apache2/ports.conf
RUN sed -i "s|<VirtualHost .*|<VirtualHost *:${PORT}>|g" /etc/apache2/sites-available/000-default.conf

RUN mv "$PHP_INI_DIR/php.ini-development" "$PHP_INI_DIR/php.ini"
`
