Description of installation and use of Docker and Docker Compose to create a temporary environment for creating a new wordpress theme in vscode. The environment consist of:

• wordpress:latest
• XDebug
• mysql 5.7
• phpmyadmin
• webpack 5

You should also install the plugin PHP Debug

Each change in the scss/js files loads the generated css and js into wordpress and automatically refreshes the page view.

Main folders are:

.vscode
└── launch.json

listen for XDebug

config
├── mysqldump.js
├── postcss.config.js
├── webpack.common.js
├── webpack.dev.js
└── webpack.prod.js

Install the Docker, manual can be found here -> Docker. Linux users must also install Docker Compose separately.

git clone https://github.com/tomik23/docker-wordpress.git
cd docker-wordpress
yarn

In the created docker-wordpress folder there is docker-compose.yml Start the console and ...

docker-compose up 

all dependencies will be incurred, this may take a while.

yarn down

all docker containers will be removed

yarn dev

runs the development environment at http://localhost:3000, js/css files are generated and loaded into wordpress in the folder wp-content/themes/assets/(css|js)

yarn prod

finally generated css/js files with separate portions, in the same folder as dev wp-content/themes/assets/(css|js), but this time they are compressed

yarn dump

dumps the database,

• wordpress http://localhost:3000
• wp-admin http://localhost/wp-admin (user/password test)
• phpMyAdmin http://localhost:8001 (user root, password test)

Example configuration file docker-compose.yml:

version: '3.7'
services:

  db:
    image: mysql:5.7
    container_name: mysql
    volumes:
      - ./database:/docker-entrypoint-initdb.d
    ports:
      - 3306:3306
    restart: on-failure
    environment:
      MYSQL_ROOT_PASSWORD: test
      MYSQL_DATABASE: wp

  phpmyadmin:
    image: phpmyadmin/phpmyadmin
    container_name: phpmyadmin
    depends_on:
      - db
    ports:
      - 8001:80
    environment:
      MYSQL_ROOT_PASSOWRD: test

  app:
    container_name: wordpress
    build:
      context: ./docker/wordpress/
