Meetup Melbourne August 2017 - Agile Integration with Apache Camel microservices in containers on Kubernetes
This document presents a tutorial on integrating Apache Camel with containerized environments like OpenShift and Kubernetes, emphasizing local setups using Minishift and Minikube. It covers building and deploying a demo client service, error handling strategies, and service discovery through environment variables and DNS. Additionally, it offers resources for further learning, including free books and upcoming webinars.
