docker run -p 80:80 --name web -d httpd

Запустить образ apache (httpd) с маппингом 80 порта контейнера на 80 порт хоста, и с назначением контейнеру имени web

docker run -p 80:80 --name web -d -v $PWD/htdocs:/usr/local/apache2/htdocs httpd

Аналогично предыдущему примеру, но папка $PWD/htdocs локальной машины монтируется в /usr/local/apache2/htdocs контейнера
