pre-run instructions

[funivan]

Sometimes we have to run WP CLI or other tools to configure instance. It would be nice to have something like this in the docker-entry

if [[ -f "/usr/local/bin/pre-run.sh" ]]; then
 /usr/local/bin/pre-run.sh
fi
ENTRYPOINT ["docker-entrypoint.sh"]
CMD ["apache2-foreground"]

WDYT about adding these lines into the docker-entrypoint.sh

If you need to add additional behavior before Apache runs, I'd suggest something like sh -c 'do-your-thing && exec apache2-foreground' as your container command.

When trying to wrap the commands like this, I receive the following error:

/usr/local/bin/docker-entrypoint.sh: line 99: exec: sh -c 'my-docker-entrypoint.sh && exec apache2-foreground': not found

Any further tips?

[tianon]

Can you give the exact line you ran? (docker run ... or your command: section in Compose YAML, for example)

Service description in my compose file:

  web:
    build:
      context: ./docker/web
      dockerfile: Dockerfile
    environment:
      WORDPRESS_DB_HOST: "db:3306"
      WORDPRESS_DB_NAME: ${MARIADB_DATABASE}
      WORDPRESS_DB_USER: ${MARIADB_USER}
      WORDPRESS_DB_PASSWORD: ${MARIADB_PASSWORD}
    ports:
      - "80:80"
      - "443:443"
    depends_on:
    - db

The corresponding Dockerfile:

FROM wordpress:6-php8.2-apache

COPY certs/* /etc/apache2/certs/
COPY ssl/local-ssl.conf /etc/apache2/sites-enabled/
COPY php.conf/* /usr/local/etc/php/conf.d/

# Enable SSL
RUN a2enmod ssl && service apache2 restart

# Overwrite the images script with our own, so it also sets custom envs
COPY --chown=www-data:www-data wp-config-docker.php /usr/src/wordpress/

# Add our own entrypoint script
COPY my-docker-entrypoint.sh /usr/local/bin/

CMD ["sh -c 'my-docker-entrypoint.sh && exec apache2-foreground'"]

Content of the script file:

#!/usr/bin/env bash

# Install wp-cli https://make.wordpress.org/cli/
curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar
chmod +x wp-cli.phar
mv wp-cli.phar /usr/local/bin/wp

wp elementor replace-urls https://localhost/ "$ENVIRONMENT_URL" --force --allow-root --path="/var/www/html"

Thank you for your help!

Ah, easy fix!

Replace:

CMD ["sh -c 'my-docker-entrypoint.sh && exec apache2-foreground'"]

With:

CMD my-docker-entrypoint.sh && exec apache2-foreground

Or:

CMD ["sh", "-c", "my-docker-entrypoint.sh && exec apache2-foreground"]

[saenglert]

Works like a charm! Again, thank you very much!
