Multiple wordpress with Docker Compose

• Simple example for hosting multiple wordpress site with docker compose
• Use docker-compose to manage site

Prerequisite

• envsubst is required
• On Ubuntu, execute apt-get install envsubst

Set up

• Clone repo: git clone https://github.com/nathando/docker-multi-wp.git
• Go to folder: cd docker-multi-wp
• Make .sh file executable sudo chmod a+x *.sh

Usage

Create new wordpress site

• Use ./docker-new.sh command with following syntax:
  ./docker-new.sh site_name wp_username wp_password wp_databasename wp_root_password
  Fill in your information for site name, username, password, etc. accordingly.
  Note: All variables should contain no space, or covered by double quotes (i.e. wp_ninja or "WP Ninja")

Start and manage with docker compose

• Use ./docker-cmd.sh just like how you use docker compose normally except we need an extra param for sub folder. all keyword will be used if you want to execute on all subfolders
• For example, to start all wordpress up: ./docker-cmd.sh all up -d
• Or to stop all wordpress: ./docker-cmd.sh all stop
• Or to stop a single wordpress: ./docker-cmd.sh [0]_wp_ninja stop

You can now access localhost:8000, localhost:8001, localhost:800x for the wordpress sites added

How it works

• The ./docker-new.sh command will fill in the pre-made template to generate a site folder in wps
• This will mark a site with index based on existing number of subfolders in wps, the subfolder's name will be in this format [$index]$site_name.
• We will run separate docker-compose on each sub folder instead of a single docker-compose for all. This makes each container independent of each others

Example of a site structure:

wps
-- [0]wp_ninja
-- -- docker-compose.yml
-- -- wp.env
-- -- db.env
-- -- storage/
