!Docker Build ![Donate]([] ![Tweet]([]

Do not use this LEMP in Production. For production, use adhocore/phpfpm then compose a stack using individual nginx, redis, mysql etc images.

adhocore/lemp is a minimal single container LEMP full stack for local development.

If you want to use PHP7.4 on LEMP stack then head over to adhocore/lemp:7.4.

It is quick jumpstart for onboarding you into docker based development. The download size is just about ~360MB which is tiny ***ing how much tools and stuffs it contains.

The docker container adhocore/lemp is composed of:

*: It is actually MariaDB 10.4.17.

Usage

Install docker in your machine. Also recommended to install docker-compose.

sh
# pull latest image
docker pull adhocore/lemp:8.0

# or if you use php 7.4, replace 8.0 with 7.4:
docker pull adhocore/lemp:7.4

# Go to your project root then run
docker run -p 8080:80 -p 8888:88 -v `pwd`:/var/www/html --name lemp -d adhocore/lemp:8.0

# In windows, you would use %cd% instead of `pwd`
docker run -p 8080:80 -p 8888:88 -v %cd%:/var/www/html --name lemp -d adhocore/lemp:8.0

# If you want to setup MySQL credentials, pass env vars
docker run -p 8080:80 -p 8888:88 -v `pwd`:/var/www/html \
  -e MYSQL_ROOT_PASSWORD=*** -e MYSQL_DATABASE=appdb \
  -e MYSQL_USER=dbuser -e MYSQL_PASSWORD=*** \
  --name lemp -d adhocore/lemp:8.0
  # for postgres you can pass in similar env as for mysql but with PGSQL_ prefix

After running container as above, you will be able to browse localhost:8080!

The database adminer will be available for mysql and postgres.

The mailcatcher will be available at localhost:8888 which displays mails in realtime.

Stop container

To stop the container, you would run:

sh
docker stop lemp

(Re)Start container

You dont have to always do docker run as in above unless you removed or lost your lemp container.

Instead, you can just start when needed:

sh
docker start lemp

PRO If you develop multiple apps, you can create multiple lemp containers with different names.

eg: docker run -p 8081:80 -v $(pwd):/var/www/html --name new-lemp -d adhocore/lemp:8.0

With Docker compose

Create a docker-compose.yml in your project root with contents something similar to:

yaml
# ./docker-compose.yml
version: '3'

services:
  app:
    image: adhocore/lemp:8.0
    # For different app you can use different names. (eg: )
    container_name: some-app
    volumes:
      # app source code
      - ./path/to/your/app:/var/www/html
      # db data persistence
      - db_data:/var/lib/mysql
      # Here you can also volume php ini settings
      # - /path/to/zz-overrides:/usr/local/etc/php/conf.d/zz-overrides.ini
    ports:
      - 8080:80
    environment:
      MYSQL_ROOT_PASSWORD: supersecurepwd
      MYSQL_DATABASE: appdb
      MYSQL_USER: dbusr
      MYSQL_PASSWORD: securepwd
      # for postgres you can pass in similar env as for mysql but with PGSQL_ prefix

volumes:
  db_data: {}

Then all you gotta do is:

sh
# To start
docker-compose up -d

# To stop
docker-compose stop

As you can see using compose is very neat, intuitive and easy. Plus you can already set the volumes and ports there, so you dont have to type in terminal.

MySQL Default credentials

• root password: *** (if MYSQL_ROOT_PASSWORD is not passed)
• user password: *** (if MYSQL_USER is passed but MYSQL_PASSWORD is not)

PgSQL Default credentials

• postgres password: *** (if PGSQL_ROOT_PASSWORD is not passed)
• user password: *** (if PGSQL_USER is passed but PGSQL_PASSWORD is not)

Accessing DB

In PHP app you can access MySQL db via PDO like so:

php
$db = new PDO(
    'mysql:host=127.0.0.1;port=3306;dbname=' . getenv('MYSQL_DATABASE'),
    getenv('MYSQL_USER'),
    getenv('MYSQL_PASSWORD')
);

You can access PgSQL db via PDO like so:

php
$pdb = new PDO(
    'pgsql:host=127.0.0.1;port=5432;dbname=' . getenv('PGSQL_DATABASE'),
    getenv('PGSQL_USER'),
    getenv('PGSQL_PASSWORD')
);

Nginx

URL rewrite is already enabled for you.

Either your app has public/ folder or not, the rewrite adapts automatically.

PHP

For available extensions, check adhocore/phpfpm#extension.

Testing mailcatcher

sh
# open shell
docker exec -it lemp sh

# send test mail
echo "\n" | sendmail -S 0 test@localhost

Then you will see the new mail in realtime at http://localhost:8888.

Or you can check it in shell as well:

sh

curl 0:88/messages
