docker-lamp

This installs a basic LAMP stack - a popular combination of open source software components, used to build dynamic web sites.

Components

The stack comprises the following components:

Name	Version	Description
Ubuntu	see docker-lamp-base	Operating system
MySQL	see docker-lamp-base	Database
Apache	see docker-lamp-base	Web server
PHP	see docker-lamp-base	Scripting language

Usage

Basic Example

Start your image binding host port 8080 to port 80 (Apache Web Server) in your container:

sudo docker run -d -p 8080:80 dell/lamp

Test your deployment:

curl http://localhost:8080/

Advanced Example 1

To start your image with:

• A data volume (which will survive a restart) for the PHP application files, in folder /app on the host. Note that, if the folder does not exist or is empty, a simple default site will be created.
• Ports 80, 443 (Apache Web Server) and 3306 (MySQL) exposed.
• A specific MySQL password.

Do:

sudo docker run -d -p 80:80 -p 3306:3306 -p 443:443 -v /app:/var/www/html \
-e MYSQL_PASS=mypass dell/lamp

You can access Apache from your browser:

http://localhost

OR

https://localhost (You must accept the SSL certificate first)

You can test your new MySQL admin password:

mysql -u admin -pmypass -h127.0.0.1 -P3306

Advanced Example 2

To start your image with:

• Two data volumes (which will survive a restart or recreation of the container). The MySQL data is available in /data/mysql on the host. The PHP application files are available in /app on the host.
• Ports 80, 443 (Apache Web Server) and 3306 (MySQL) exposed
• A named container (lamp)

Do:

sudo docker run -d -p 80:80 -p 3306:3306 -p 443:443 -v /app:/var/www/html \
-v /data/mysql:/var/lib/mysql --name lamp dell/lamp

Administration

Connecting to MySQL

The first time that you run your container, a new user admin with all privileges will be created in MySQL with a random password. To get the password, check the logs of the container.

sudo docker logs <container_id>

You will see an output like the following:

====================================================================
You can now connect to this MySQL Server using:

  mysql -u admin -p47nnf4FweaKu -h<host> -P<port>

Please remember to change the above password as soon as possible!
MySQL user 'root' has no password but only allows local connections
=====================================================================

In this case, 47nnf4FweaKu is the password allocated to the admin user.

You can then connect to MySQL:

mysql -u admin -p47nnf4FweaKu -h127.0.0.1 -P3306

Note that the root user can't be used for connections from outside the container. Please use the admin user instead.

Updating the Application

The PHP application files are available at path /var/www/html on the host. If you are not using a host volume, you will need to use nsenter to attach to the container.

Connecting to MySQL from the Application

The bundled MySQL server has a root user with no password for local connections. Simply connect from your PHP code with this user:

<?php
$mysql = new mysqli("localhost", "root");
echo "MySQL Server info: ".$mysql->host_info;
?>
