DevNexus-2017

Slide deck and code samples for the Modern Service Management With Consul and Vault session, presented at DevNexus 2017.

Framework-agnostic config management demo

A demo of using Consul and Vault to manage configuration properties across multiple environments, and multiple applications within each (including local development, loading from a properties file instead of Consul/Vault).
Allows for separation between "non-secret" properties that can be managed by developers (e.g. JDBC URL's), versus "secret" properties that should be managed only be authorized persons (e.g. usernames/passwords). Works with any JVM application.

• config-properties - Properties files, and a batch processor that syncs the non-secret properties with Consul.
• config-client-lib - Client library that loads properties from Consul and Vault.
• config-sample-app - Demo web app, using the client library to load properties.

Spring Cloud Config demo

A Spring-specific demo of using Spring Cloud Config to manage configuration properties. Uses a "composite environment repository" (coming in the next GA release)... which allows "non-secret" properties to be stored in Git, and "secret" properties stored in Vault.

• spring-config-properties - Properties files.
• spring-config-server - Instance of Spring Cloud Config Server, configured as a composite environment repository.
• spring-config-sample-app - Demo Spring Boot app, using the Spring Cloud Config Client to load properties.

TLS Security with Vault as a CA demo

• kafka-tls-demo - Instructions for configuring Kafka with Vault, sample message producer and consumers.

Vault client

• vault-java-driver - An open-source Java client for Vault, used by the demos above.
