All in one Wordpress Dockerfile: Wordpress + Nginx + MySQL + SSL

Forked from (https://github.com/cowfox/docker-wordpress-nginx-fpm-cache-ssl). Added local MySQL to Dockerfile and config for an all in one solution.

Docker file with related scripts and config files to help build a Docker container that runs the following pieces out-of-the-box:

PHP-FPM.
Nginx with fastcgi-cache and fastcgi_cache_purge.
Opcache.
MySQL
Wordpress with the latest version.

Also, it provides the following optional scripts:

Add existing SSL cert files into Nginx config.
Auto-generate SSL cert and add into Nginx config. It is done through letsencrypt (https://letsencrypt.org/)
Auto-download a pre-defined list of Wordpress plugins.

Usage

The docker image comes with the default CMD script - init.sh, which mainly does:

Set up default env. variables, such as DB host name, DB access info, etc.
Modify the wp-config.php based on the env. variables.
Update Server Name to all other config files.
Start supervisord service.

It takes five env. variables:

SERVER_NAME - the server name that serves the Wordpress.
DB_DATABASE - the local MySQL database name
DB_PASSWORD - the root Mysql password
WP_PASSWORD - the password of the Mysql username that accesses to the database.

If using docker run CMD to build the container, be sure to use --env to add these variables.

Docker Compose

When using docker compose config file docker-compose.yml to build the containers, it would be much simpler. If using link between wordpress and mysql containers, the init.sh script can automatically get the DB access info by using the link environment variables.

Seems that link can only work with version 1 of docker compose config file.

The docker compose config file would be like this.

wordpress:
  image: snapturtle/docker-wordpress-ssl-nginx-mysql
  environment:
    SERVER_NAME: "example.com"
  ports:
    - "80:80"
    - "443:443"

Please note: when linking the mysql DB, be sure to assign it with an alias db, since init.sh script uses it to load the link environment variables.

Optional Scripts

When container being built, all the three optional scripts will be copied to /addon/ folder inside the container.

/addon/wp-install-plugins.sh - It helps download a pre-defined list of Wordpress plugins, in the variable PLUGINS. By default, it only has nginx-helper in the list. When using this script, it is recommended to modify this script (you can grab it from Github) and then mount it back to the container when building it.
/addon/ssl.sh - It helps add existing SSL cert file to Nginx config. The script uses there ENV. variables.
- SSL_TRUSTED_CERT_FILE - The file path to the trusted cert file. The path must be inside the container.
- SSL_CERT_FILE - The file path to the cert file.
- SSL_CERT_KEY_FILE - The file path to the private key file.
/addon/letsencrypt/ssl-letsencrypt.sh - It help auto-generate the letsencrypt SSL cert and add to Nginx config. The script uses there ENV. variables.
- LE_WEBROOT - The web root that letsencrypt uses. By default, it is /tmp/letsencrypt-auto.
- LE_INI_FILE - The file path to the ini files that used to generate the SSL cert. By default, it is /letsencrypt-le.ini.
- LE_ACME_FILE - The file path to the location block of ACME Challenge that letsencrypt uses. By default, it is /nginx-acme.challenge.le.conf.

For the file letsencrypt-le.ini and nginx-acme.challenge.le.conf, you can check the Github repo (/config/addon/) for example.

Customize it

Besides the above scripts and sample files, Github repo also ships with the config files that Nginx uses, like nginx.conf, site config, SSL config, etc. If needed to modify them, just git clone from Github, modify them and then do docker image build on your side.
