Setting up WordPress, MySQL, Nginx proxy and SSL certificates in Docker

Tue, 03 Aug 2021 00:00:00 +0500

building and running the docker setup
- mysql
- wordpress
- nginx proxy
- auto-renewing SSLs
we’ll have a data folder where we’ll keep the files/data we need to mount inside docker containers as volumes
wordpress and database will be our directories for the WordPress site and the MySQL database files. These will be in the user’s home directory (and not in the data folder)
we’ll have a .env file for the secrets. .env in the project’s root is picked up by Docker automatically. You can reference environment variables inside docker-compose.yml like you reference bash variables: ${MYSQL_PASSWORD}

Installing packages globally

If you are installing packages globally as the root user, you get the EACCES: permission denied error. Which is why it is recommended that you install node with a version manager, like nvm. (Or manually change the default directory for npm)

You don’t need to install the long manual way, docker.io is already provided as a package in the Ubuntu repos and the version is fairly up to date (19.03.8-0ubuntu1 as of this writing, which is the latest version). You can check which version comes with the commandapt info docker.io
