  1. RUN a CONTAINER (I) Start new container from an image:  docker run IMAGE_NAME (II) And assign it a name:  docker run --name CONTAINER _NAME IMAGE_NAME (III) To map a port:  docker run -p HOST_PORT:CONTAINER_PORT IMAGE (IV) To MAP all port:  docker run -P IMAGE_NAME (V) And Start a Container in background:  docker run -d IMAGE_NAME (VI) And Assign it a HOST NAME:  docker run --hostname HOSTNAME IMAGE_NAME (VII) And add a DNS entry or HOST entry in /etc/hosts file:  docker run  --add-host  HOSTNAME:IP IMAGE (VIII) And map a local directory (volume) to a container:  docker run -v HOST_DIR:TARGET_DIR IMAGE_NAME (IX)   ALL IN ONE Example :  docker run --name my_container -p 80:80 -v /home/data/:/var/www/html/--add-host test.ac.in:10.246.10.6 --hostname nginx_host -d nginx 2.

  FIRST METHOD Before we install Drupal, we need to deploy MySQL. This is easily done with Docker by running the following command. In this command, replace “MYSQL-NAME” with a name for your MySQL Docker container. Also, replace “MYSQL-PASSWORD” with a new password for the container’s MySQL instance. Record both of these for later. docker run --name MYSQL-NAME -e MYSQL_ROOT_PASSWORD=MYSQL-PASSWORD -d mysql:latest Deploying and Configuring Drupal with Docker Our next step is to deploy a Drupal Docker container, connect it to your MySQL container, and finish configuring Drupal. Follow these steps. Run the following command. Replace “DRUPAL-NAME” with a name for your Drupal container. Replace “MYSQL-NAME” and “MYSQL-PASSWORD” with the values you used for your MySQL Docker container in the previous section. docker run --name DRUPAL-NAME --link MYSQL-NAME:mysql -p 8080:80 -e MYSQL_USER=root -e MYSQL_PASSWORD=MYSQL-PASSWORD -d drupal Go to  http://YOUR.VPS.IP:8080/  in ...
