Introduction

Docker-LAMP-CGI is a fork of Docker-LAMP by Matt Rayner. It is a docker image that include the phusion baseimage (20.04 variety), along with a LAMP stack (Apache, MySQL and PHP) all in one handy package. Compared to the upstream version, Docker-LAMP-CGI adds support to CGI scripts.

Image Versions

Component	latest
Apache	2.4.41
MySQL	8.0.26
PHP	8.0.10
phpMyAdmin	5.1.1

Using the image

On the command line

This is the quickest way

# Launch a 20.04 based image with PHP 8
docker run -p "80:80" -v ${PWD}/app:/app gdsyzxzcx/lampcgi:latest

With a Dockerfile

FROM gdsyzxzcx/lampcgi:latest

# Your custom commands

CMD ["/run.sh"]

MySQL Databases

By default, the image comes with a root MySQL account that has no password. This account is only available locally, i.e. within your application. It is not available from outside your docker image or through phpMyAdmin.

When you first run the image you'll see a message showing your admin user's password. This user can be used locally and externally, either by connecting to your MySQL port (default 3306) and using a tool like MySQL Workbench or Sequel Pro, or through phpMyAdmin.

If you need this login later, you can run docker logs CONTAINER_ID and you should see it at the top of the log.

Creating a database

So your application needs a database - you have two options...

1. PHPMyAdmin
2. Command line

PHPMyAdmin

Docker-LAMP comes pre-installed with phpMyAdmin available from http://DOCKER_ADDRESS/phpmyadmin.

NOTE: you cannot use the root user with PHPMyAdmin. We recommend logging in with the admin user mentioned in the introduction to this section.

Command Line

First, get the ID of your running container with docker ps, then run the below command replacing CONTAINER_ID and DATABASE_NAME with your required values:

docker exec CONTAINER_ID  mysql -uroot -e "create database DATABASE_NAME"

Adding your own content

The 'easiest' way to add your own content to the lamp image is using Docker volumes. This will effectively 'sync' a particular folder on your machine with that on the docker container.

The below examples assume the following project layout and that you are running the commands from the 'project root'.

/ (project root)
/app/ (your PHP files live here)
/mysql/ (docker will create this and store your MySQL data here)

In english, your project should contain a folder called app containing all of your app's code. That's pretty much it.

Adding your app

The below command will run the docker image gdsyzxzcx/lampcgi:latest interactively, exposing port 80 on the host machine with port 80 on the docker container. It will then create a volume linking the app/ directory within your project to the /app directory on the container. This is where Apache is expecting your PHP to live.

docker run -i -t -p "80:80" -v ${PWD}/app:/app gdsyzxzcx/lampcgi:latest

Persisting your MySQL

The below command will run the docker image gdsyzxzcx/lampcgi:latest, creating a mysql/ folder within your project. This folder will be linked to /var/lib/mysql where all of the MySQL files from container lives. You will now be able to stop/start the container and keep your database changes.

You may also add -p 3306:3306 after -p 80:80 to expose the mysql sockets on your host machine. This will allow you to connect an external application such as SequelPro or MySQL Workbench.

docker run -i -t -p "80:80" -v ${PWD}/mysql:/var/lib/mysql gdsyzxzcx/lampcgi:latest

Doing both

The below command is our 'recommended' solution. It both adds your own PHP and persists database files. We have created a more advanced alias in our .bash_profile files to enable the short commands ldi and launchdocker. See the next section for an example.

docker run -i -t -p "80:80" -v ${PWD}/app:/app -v ${PWD}/mysql:/var/lib/mysql gdsyzxzcx/lampcgi:latest

.bash_profile alias examples

The below example can be added to your ~/.bash_profile file to add the alias commands ldi and launchdocker.

# A helper function to launch docker container using gdsyzxzcx/lampcgi with overrideable parameters
#
# $1 - Apache Port (optional)
# $2 - MySQL Port (optional - no value will cause MySQL not to be mapped)
function launchdockerwithparams {
    APACHE_PORT=80
    MYSQL_PORT_COMMAND=""
    
    if ! [[ -z "$1" ]]; then
        APACHE_PORT=$1
    fi
    
    if ! [[ -z "$2" ]]; then
        MYSQL_PORT_COMMAND="-p \"$2:3306\""
    fi

    docker run -i -t -p "$APACHE_PORT:80" $MYSQL_PORT_COMMAND -v ${PWD}/app:/app -v ${PWD}/mysql:/var/lib/mysql gdsyzxzcx/lampcgi:latest
}
alias launchdocker='launchdockerwithparams $1 $2'
alias ldi='launchdockerwithparams $1 $2'

Example usage

# Launch docker and map port 80 for apache
ldi

# Launch docker and map port 8080 for apache
ldi 8080

# Launch docker and map port 3000 for apache along with 3306 for MySQL
ldi 3000 3306

Developing the image

Building and running

# Clone the project from Github
git clone https://github.com/kad-ecoli/docker-lamp-cgi
cd docker-lamp-cgi

# Build the images
docker build --network=host -t=gdsyzxzcx/lampcgi:latest -f ./latest/Dockerfile .

# Run the image as a container
docker run -d -p "3000:80" gdsyzxzcx/lampcgi:latest

# Sleep to allow the container to boot
sleep 30

# check container ID
docker ps | grep gdsyzxzcx/lampcgi | cut -f1 -d' '

# check container IP, where ${docker_machine_ID} is the ID obtained above
docker inspect ${docker_machine_ID) |grep IPAddress

# Curl out the contents of our new container, where ${docker_machine_ip} is the IP address obtained above
curl "http://${docker_machine_ip}:3000/"

Testing

We use docker-compose to setup, build and run our testing environment. It allows us to offload a large amount of the testing overhead to Docker, and to ensure that we always test our image in a consistent way that's not affected by the host machine.

One-line testing command

We've developed a single-line test command you can run on your machine within the docker-lamp directory. This will test any changes that may have been made, as well as comparing installed versions of Apache, MySQL, PHP and phpMyAdmin against those expected.

docker-compose -f docker-compose.test.yml -p ci build; docker-compose -f docker-compose.test.yml -p ci up -d; cd tests && ./test.sh; echo "Exited with status code: $?";

So what does this command do?

docker-compose -f docker-compose.test.yml -p ci build;

First, build that latest version of our docker-compose images.

docker-compose -f docker-compose.test.yml -p ci up -d;

Launch our docker containers (web2004-php8 etc.) in daemon mode.

cd tests && ./test.sh;

Change into the test directory and run out tests

echo "Exited with status code: $?"

Report back whether the tests passed or not
