Z-Push Container Image

This repository contains a Dockerfile and related Kubernetes configuration examples for deploying the Z-Push ActiveSync implementation in a containerised fashion.

Supported features

The image, as it is built now, supports the following Z-Push features:

• IMAP backend
• Autodiscover
• memcached IPC implementation
• SQL state storage (including using PostgreSQL as a backend, which is a non-standard configuration)

Configuration

Z-Push is usually configured via PHP define() calls in configuration files. The supplied container image augments a couple of these define()s with the ability to load data from environment variables. The name of the environment variables is identical to the name of the defined constant with ZPUSH prepended. For a complete list of currently overridable settings cf. kubernetes/z-push.env.

Kubernetes Example

The kubernetes/ subdirectory contains a kustomization.yaml file illustrating how to deploy a Z-Push installation into a Kubernetes cluster.
