Static files don’t fully deploy on a docker-based deployment

I’m having trouble implementing the deploy strategy described in e.g. https://info2.magento.com/rs/585-GGD-959/images/The%20New%20Magento%202.2%20Deployment%20Capabilities%20%26%20Patterns.pdf

I build a docker image ready to be deployed as shown on pages 8 or 9 of the document, using a fresh magento + composer.json + own modules + own themes + env.php + config.php + an initial sql dump. This is used in docker compose to create a local env.

When I start the env I see the site without styles, due to many static files being missing. For example /static/version1643293995/frontend/Magento/luma/es_ES/css/print.css.

I can generate the missing statics if I log into the running container and run bin/magento setup:static-content:deploy -f, but this clearly defeats the purpose of this deployment.

I would appreciate any hint on what I’m missing here.

Thanks!

The Dockerfile is as follows:

# syntax = docker/dockerfile:1.3
FROM ${REGISTRY}/magento-base:2.4.3

ENV APACHE_DOCUMENTROOT="/opt/magento"
ENV MAGENTO_HOME="/opt/magento"

# COPY DATA
COPY --chown=www-data:www-data magento/ /opt/magento/
RUN chown -R www-data:www-data /opt/magento/pub/* /opt/magento/var/*

# Build

RUN composer update --no-cache 
    && bin/magento setup:di:compile 
    && bin/magento setup:static-content:deploy -f 

COPY --chown=www-data:www-data files/ /

WORKDIR /opt/magento
