ndthuan/wordpress repository overview

⁠ndthuan/wordpress

docker pull ndthuan/wordpress

WordPress Docker image with easy-to-customize PHP and sSMTP configs.

⁠Problems this image attempts to solve

You want to deploy a number of WP containers with slightly different PHP configs but you don't want to create a new ini file or a new Dockerfile for each of them. You want to change it by specifying some environment variables.

With this image, you can:

• change basic but important PHP configs like post limit, upload limit, session storage...
• configure sSMTP to send emails from a Docker container. When combined with something like Gmail SMTP, it ensures maximum email deliverability.

⁠The base image

This image is based on the standard image wordpress:php7.3-apache. Packaged WP version is 5.2 but it can be upgraded to the latest version using WP's update tool without an issue.
