## 1. About Docker
Docker is an open source application container engine that allows developers to package their applications and dependencies into a portable image that can then be distributed to any popular Linux or Windows machine, as well as virtualization. Containers are completely sandboxed and have no interface with each other.

About Drupal
Drupal is an open source content management Framework (CMF) written in PHP. It consists of a content management system (CMS) and a PHP development Framework (Framework). It has won the World’s Best CMS Award for many years running and is the most famous WEB application based on PHP. At the end of 2011, 13,802 WEB experts worked on Drupal development; Drupal is used by 729,791 web designers in 181 languages in 228 countries. Famous cases include: The United Nations, the White House, the Department of Commerce, the New York Times, Warner, Disney, Fedex, SONY, Harvard University, Ubuntu, etc.

Drupal runtime environment
Apache (Recommended)
You can use Apache’s mod_rewrite to extend Drupal’s Clean url. In Drupal8, clean urls are turned on by default and cannot be turned off, so in order for Drupal to work properly, Mod_rewrite needs to be installed and enabled.
The virtual host must be configured to include AllowOverride All to allow Drupal. Htaccess files to work.
Database
MySQL 5.5.3/MariaDB 5.5.20/Percona Server 5.5.8 or higher with PDO and an InnoDB-compatible primary storage engine,
PostgreSQL 9.1.2 or higher with PDO,
SQLite 3.6.8 or who
PHP
Drupal 8: PHP 5.5.9 or higher
Three steps to get
See the configuration environment, many beginners will be discouraged. Thanks to Docker’s image and container technology, we can save ourselves the trouble of configuring the environment. Moreover, the environment can be identical to the live environment, saving us the trouble of deployment and maintenance.
Installing the Drupal8 runtime environment with Docker is a three-step process that requires two containers to be installed.
Step 1 Install the database
On the command line, enter the following command:
docker run \
-e MYSQL_ROOT_PASSWORD=admin \
-e MYSQL_DATABASE=drupal8 \
-e MYSQL_USER=drupal8 \
-e MYSQL_PASSWORD=drupal8 \
-v mariadb:/var/lib/mysql \
-d \
--name mariadb \
mariadb
Copy the codeThe first line means to create the container, the second through sixth lines are the database configuration parameters, -d is to run the container in the background, –name gives the container a name, and the last line is the image name.
The full understanding is to create a container named Mariadb running in the background from the Mariadb image, following the specified database configuration parameters. If there is no mariadb image locally, the container is automatically pulled from the Docker Hub.
The running results are as follows:
Unable to find image 'mariadb:latest' locally
latest: Pulling from library/mariadb

Copy the codeStep 2 install the web server and Drupal source code
On the command line, enter the following command:
docker run \
--name drupal8 \
--link mariadb:mysql \
-p 80:80 \
-d \
drupal
Copy the codeThe drupal image creates a container named Drupal8 that runs in the background. If no drupal image is available locally, the container is automatically pulled from the Docker Hub and then created. — Link connection named mariadb container (created in the first step), take a link named mysql, which will be used in the third installment of Drupal installation. Remember that! -p maps port 80 of the container to port 80 of the host. Then the browser of the host can directly access localhost.
The running results are as follows:
Unable to find image 'drupal:latest' locally
latest: Pulling from library/drupal

Copy the codeSince we did not specify a version number for the image when we installed the container, the latest version is automatically pulled, which means the latest version of the image.
After installing both containers, we can view containers and images in Docker. View containers:

Type localhost in the browser of the host machine (which is our current computer) to start the Drupal installation page. Note the database connection configuration:
