In this note, I wanna an automatical setting up of basic things.

👉 Install Docker by following this note.

WP basic without backup #

Make a folder name mysite containing,

mysite
|-- docker-compose.yml # main file
|-- backup # contains backup files using AIO WP Migration plugins
|-- plugins # contains plugins
|-- themes # contains templates
|-- wordpress # main site's sources

In the docker-compose.yml,

version: '3.1'

services:

wordpress:
image: wordpress
restart: always
ports:
- 8080:80
environment:
WORDPRESS_DB_HOST: db
WORDPRESS_DB_USER: exampleuser
WORDPRESS_DB_PASSWORD: examplepass
WORDPRESS_DB_NAME: exampledb
volumes:
- './html/:/var/www/html/'
- './plugins/:/var/www/html/wp-content/plugins/'
- './themes/<theme>/:/var/www/html/wp-content/themes/<theme>'

db:
image: mysql:5.7
restart: always
environment:
MYSQL_DATABASE: exampledb
MYSQL_USER: exampleuser
MYSQL_PASSWORD: examplepass
MYSQL_RANDOM_ROOT_PASSWORD: '1'

Start the container,

cd mysite
docker-compose up -d
# check running containers
docker ps -a

Browse http://localhost:8080 to install wordpress by gui.

Debug #

In the case you wanna see the list of users or access to the mysql environement,

# connect to MySQL running container
docker exec -it <container_db> bash

# connect to mysql database
mysql -u wordpress -p

# list all users
SELECT host, user FROM mysql.user;

Install WP-CLI #

# Download wp-cli
curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar
# Make it executable
chmod +x wp-cli.phar
# Move it into /usr/local/bin/wp
sudo mv wp-cli.phar /usr/local/bin/wp
# Check whether the installation worked
wp --info

For example, activate all-in-one-wp-migration (already copied / placed in folder plugins)

wp plugin activate all-in-one-wp-migration --allow-root
