1. Use wordpress:latest to create ssl version of wordpress container

Create Dockerfile file

FROM wordpress:latest

RUN apt-get update && \
	apt-get install -y  --no-install-recommends ssl-cert && \
	rm -r /var/lib/apt/lists/* && \
	a2enmod ssl && \
	a2ensite default-ssl

EXPOSE 80
EXPOSE 443

run

$ docker build -t ssl_wordpress:1.0 .

2. Create the folder structure
folder-structure

3. Create docker-compose.yml file

version: '3.1'
services:
  my-wordpress:
    image: ssl_wordpress:1.0
    container_name: alextechtips_wp
    restart: always
    volumes:
      - ./wordpress:/var/www/html/wp-content
    ports:
      - 80:80
      - 443:443
    links:
      - mysqlserver:mysql
    depends_on:
      - mysqlserver

  mysqlserver:
    image: mariadb:latest
    container_name: alextechtips_sql
    restart: always
    volumes:
      - ./db:/var/lib/mysql
    ports:
      - 3306:3306
    environment:
      MYSQL_ROOT_PASSWORD: password

4. Run the containers use docker-compose

$ docker-compose up -d

5. After the containers up and the WordPress setup has been run, then you need to navigate to the wp-content folder and change the owner and group to www-data, this will enable you to add new plugins and themes.
change-owner-group
because I mount the wp-content to host’s wordpress folder, so just change the folder owner and group to www-data.

$ sudo chown -R www-data:www-data wordpress
