how to create customized Wordpress docker image and remove default plugins and themes from official docker image

Question

you can use wp cli to do it in dokcer container instance launching.

1. We need add shell script in a official image file in /usr/local/bin/docker-entrypoint.sh. So use command 'docker cp' copy the file to local path.

2. edit local file: find the line(at 67):

    echo >&2 "Complete! WordPress has been successfully copied to $PWD"
   

3. add below shell script after that line.

    curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar
    php wp-cli.phar --info
    chmod +x wp-cli.phar
    mv wp-cli.phar /usr/local/bin/wp
    wp --info
    wp plugin list --allow-root
    wp plugin delete hello --allow-root
    wp plugin delete akismet --allow-root
    wp theme list --allow-root
    wp theme delete twentynineteen --allow-root
    wp theme delete twentytwenty --allow-root
    wp theme delete twentytwentyone --allow-root
   

4. Add below lines in your Dockerfile

    FROM wordpress:latest
   
    ADD ./wp-content /var/www/html/wp-content
    ADD ./wp-config.php /var/www/html/wp-config.php
    ADD ./vendor /var/www/html/vendor
    ADD ./docker-entrypoint.sh /usr/local/bin/docker-entrypoint.sh
   
    WORKDIR /var/www/html
    EXPOSE 80
    CMD ["apache2-foreground"]
