This is what I use for developing standard WordPress sites. It can also be used for hosting the site, but I recommend using a proper host. Configured to use SSL in all environments.
First, create an .env to the project root, using .env_sample as base.
Read on.
wordpress/ Bedrock style WordPress installation, managed by Composer.
Create an .env file using .env_sample as base.
Run composer install in the directory, and make changes to the config as you see fit in config/ directory. Most is configured with .env later on.
letsencrypt/ Scripts for certificates.
Run ./letsencrypt/letsencrypt/letsencrypt-init.sh yourdomain.com BEFORE running docker-compose up for the first time. Follow the script.
If you're running locally, you might want to run ./letsencrypt/letsencrypt/self-signed-init.sh yourdomain.com.
If you ignore the above advice, Nginx will not start.
nginx/ Contains nginx configuration. Duh.
Create .conf and .inc files from the template.* files using envsubst, sed, or any other text editor. Replace ${SITE_URL} with your domain, without www.
Next, create entries to your computers hosts file.
127.0.0.1 yoursite.com
When everything is configured, run docker-compose up.
docker-compose exec wordpress bash, cd wordpress, and run any command you want.
Should work out of the box. Use Mercator if you need to have different domains, and follow the official guide: https://wordpress.org/support/article/create-a-network/
