Como hacer 'wp package install' en wpcli docker container

Usando docker-compose con un config como

docker-compose.yml

# ...
  wpcli:
    depends_on:
      - wordpress
    image: wordpress:cli
    user: 1000:1000
    command: tail -f /dev/null
    volumes:
      - ./wordpress:/var/www/html
    environment:
        - WORDPRESS_DB_HOST=mariadb:3306
        - WORDPRESS_DB_USER=wordpress
        - WORDPRESS_DB_NAME=wordpress
        - WORDPRESS_DB_PASSWORD=${MARIADB_PASSWORD}

# ...
  wpcli:
    depends_on:
      - wordpress
    image: wordpress:cli
    user: 1000:1000
    command: tail -f /dev/null
    volumes:
      - ./wordpress:/var/www/html
    environment:
        - WORDPRESS_DB_HOST=mariadb:3306
        - WORDPRESS_DB_USER=wordpress
        - WORDPRESS_DB_NAME=wordpress
        - WORDPRESS_DB_PASSWORD=${MARIADB_PASSWORD}

Necesitas instalar el package en el container como root para evitar

wp_package_install_error.txt

Error: Composer directory '/.wp-cli/packages' for packages couldn't be created: mkdir(): Permission denied

Error: Composer directory '/.wp-cli/packages' for packages couldn't be created: mkdir(): Permission denied

Usa el siguiente comando para instalar un package

wp_package_install_root.sh

docker-compose exec -u root wpcli wp package install wp-cli/profile-command:@stable --allow-root

docker-compose exec -u root wpcli wp package install wp-cli/profile-command:@stable --allow-root
