# PostfixAdmin
[![Docker Pulls](https://img.shields.io/docker/pulls/volkerraschek/postfixadmin)](https://hub.docker.com/r/volkerraschek/postfixadmin)
[![Artifact Hub](https://img.shields.io/endpoint?url=https://artifacthub.io/badge/repository/volker-raschek)](https://artifacthub.io/packages/search?repo=volker-raschek)
This is an alternative project to build a container image for
[PostfixAdmin](https://github.com/postfixadmin/postfixadmin).
The main goal of this alternative image is to support a kubernetes deployment via helm. Furthermore, the container image
support configuring via [environment variables](#supported-environment-variables).
To deploy PostfixAdmin via `helm` checkout the repository on
[artifacthub.io](https://artifacthub.io/packages/helm/volker-raschek/postfixadmin) for more details.
## Supported environment variables
This list is an overview over some important environment variables. The environment variables are composed on the key of
the PHP configuration with the prefix `POSTFIXADMIN_`. You can take an example
[configuration](https://github.com/postfixadmin/postfixadmin/blob/master/config.inc.php) from the upstream project.
