'How to install ZeroMQ for PHP on an Alpine Linux container?

To be able to push notifications via WebSockets from PHP using Ratchet, I need to install ZeroMQ as stated in the documentation. However I didn't find any information about how to do it for Alpine Linux. Most of the time what we can find is with apt-get, for example here. Same about the Docker images (Dockerfile) available on Docker hub.

Since the dependencies and their name seem different, how to do it with Alpine?

For those who face the same situation, I finally found how to do it:

FROM php:7-cli-alpine
RUN apk add autoconf gcc libzmq zeromq-dev zeromq coreutils build-base
RUN pecl install zmq-beta \
   && docker-php-ext-enable zmq

In php:8.0-fpm-alpine, pecl install zmq-beta threw an error and failed to compile, so I used this command:

FROM php:8.0-fpm-alpine
ENV COMPOSER_ALLOW_SUPERUSER 1
RUN set -eux && \
  apk add --update-cache --no-cache libzmq zeromq-dev zeromq && \
  apk add --update-cache --no-cache --virtual=.build-php-dependencies \
  autoconf gcc coreutils build-base git && \
  git clone https://github.com/mkoppanen/php-zmq.git && \
  cd php-zmq && \
  phpize && \
  ./configure && \
  make && \
  make install && \
  docker-php-ext-enable zmq && \
  apk del .build-php-dependencies
