managah/wordpress

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

docker pull managah/wordpress:[tag]

Supported tags:

• php7.3-apache
• php7.4-apache
• php8.0-apache
• php8.1-apache

latest won't work so you always have to specify a tag.

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.
