Has anyone managed to use Blackfire together with Swoole? I've been trying to set it up for a few days, but without success.

I'm calling the following script in the PHP-CLI Swoole Dockerfile:

#!/usr/bin/env bash



# @see https://blackfire.io/docs/up-and-running/installation



set -e



apt-get update

apt-get install -y gnupg --no-install-recommends



# Configure the Debian Repository

wget -q -O - https://packages.blackfire.io/gpg.key | apt-key add -

echo "deb http://packages.blackfire.io/debian any main" | tee /etc/apt/sources.list.d/blackfire.list

apt-get update



# Install and Configure the Agent

echo "$(date '+%Y-%m-%d %H:%M:%S,%3N') $(tput bold)$(tput setaf 4)INFO$(tput sgr0) Install and Configure the Agent."

apt-get -o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold" install blackfire

blackfire agent:config --server-id=MY-SERVER-ID --server-token=MY-SERVER-TOKEN

/etc/init.d/blackfire-agent restart



# Install the PHP Probe

echo "$(date '+%Y-%m-%d %H:%M:%S,%3N') $(tput bold)$(tput setaf 4)INFO$(tput sgr0) Install the PHP Probe."

apt-get -o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold" install blackfire-php



# Clear

My Answer:
Dockerfile
FROM php:7.4-cli

# Install Blackfire
RUN version=$(php -r "echo PHP_MAJOR_VERSION.PHP_MINOR_VERSION;") \
&& curl -A "Docker" -o /tmp/blackfire-probe.tar.gz -D - -L -s https://blackfire.io/api/v1/releases/probe/php/linux/amd64/$version \
&& tar zxpf /tmp/blackfire-probe.tar.gz -C /tmp \
&& mv /tmp/blackfire-*.so $(php -r "echo ini_get('extension_dir');")/blackfire.so \
&& echo "extension=blackfire.so" > $PHP_INI_DIR/conf.d/blackfire.ini \
&& rm /tmp/blackfire-probe.tar.gz

# Install Swoole
RUN pecl install swoole && docker-php-ext-enable swoole

CMD ["php", "-S", "0.0.0.0:8000"]


Make sure to replace `PHP_MAJOR_VERSION` and `PHP_MINOR_VERSION` with the appropriate values for your PHP version. Also, ensure that you have the necessary permissions to install extensions in your Docker container.

After building and running your Docker container, you should be able to use Blackfire together with Swoole. Let me know if you encounter any issues.
