Support Eclipse MicroProfile Config

In  microprofile

Overview

Support Eclipse MicroProfile Config for applications deployed in WildFly. The integration uses the smallrye-config component to provide the MicroProfile Config implementation.

The code in smallrye-config and in the proposed WildFly extension has already been developed in the wildfly-microprofile-config and was used in WildFly Swarm.

This RFE moves the extension code to WildFly so that applications deployed on WildFly can also benefit from the MicroProfile Config API.

Requirements

  • Support Eclipse MicroProfile Config for any applications deployed in WildFly.

  • The extension is added to all configuration provided by WildFly (standalone and domain mode).

Implementation Plan

  • Add dependencies to smallrye-config and microprofile-config-api artifacts

  • Add a new microprofile-config-smallrye extension to provide Config support for deployments.

  • Add subsystem resources to enhance MicroProfile Config (e.g to support OpenShift ConfigMaps, store properties in WildFly configuration XML files, etc.)

Test Plan

  • smallrye-config component is passing the MicroProfile Config TCK during its release process.

  • WildFly integration test suite will be enhanced with tests that deploys Java archives which uses the MicroProfile Config API.

Community Documentation

The feature will be documented in WildFly Admin Guide (in a new MicroProfile Config section).
